Operating Instructions for Thermoline Plant Growth Cabinet Model Number TPG-5000-TH-Co2/TPG-6000-TH-Co2. Location. Locate the cabinet on a firm level surface, in a well-ventilated area. The base of the cabinet is fitted with castors to allow ease of movement, and once in position it can be fixed and levelled, using the lock-down feet provided adjacent to the castors on the base frame. To adjust the level, use a spanner to undo the screws until the head of the screws raise the cabinet off the ground. It is important that the cabinet is levelled reasonably accurately, in order for water to drain out of the drain tube at the rear of the cabinet. (Use a spirit level if necessary.) Connection of Services. All services should enter the cabinet through the roof. All penetrations have been made in the sheet metal and are labelled accordingly. Refrigeration & Installation of Remote Air Cooled Condenser. The refrigeration compressor and receiver are located in the control enclosure. Hot gas and liquid connection are fitted with shut off valves that are located in this enclosure. The termination points are at the roof of the cabinet and are labelled accordingly. An air-cooled condenser is supplied with the chamber, which has to be located in a suitable position, preferably outside the building. Please remember that the condenser location should be selected taking into account: Solar radiation. The potential for the build up of debris, such as leaves, paper etc. Ease of access for cleaning. A Qualified Technician should perform installation of the Remote Air Cooled Condenser. Failure to do this may result in premature failure of the refrigeration system. Installation of the Remote Air Cooled Condenser consists of: 1. Making connections for the hot gas and liquid lines between the cabinet and the external condenser. Use ½ inch copper pipe for both hot gas and liquid. Do not open Ball Valves. 2. Pressure test for leaks. Then evacuate the refrigerant lines. (Use Schrader connectors). 3. Then charge the lines with R507 refrigerant. Use a Liquid charge. 4. Open all four ball valves. 5. Making electrical connections between the electrical terminations in the controls enclosure and the key isolating switch on the Remote Air Cooled Condenser. Check Fan Rotation. 1. Once the remote Air Cooled Condenser is installed, plug the Main Power Supply Lead in to a suitable power supply and turn on the Main switch. 2. Open the Electrical Enclosure door and make sure the Air Circulating Motors (Black Coloured Motor) are turn in the direction as shown by the arrow on the Motor. If the Motor is turning in the opposite direction. Disconnect the Main Power Supply Lead and swap Active Line 1 with Active Line 2. This will cause the motor to rotate in the opposite (correct) direction. 4
Electrical. The chamber is supplied with a flexible power lead with a 32 amp, 5-pin male plug attached. This needs to be plugged into a 415-volt, 3 phase and Neutral, 32 amps supply socket. Water Supply. Protruding from the roof is a ¼ copper tube attached to a standard hose connector. This is labelled Water In. Connect the water supply accordingly. Water should preferable be filtered and maintained with a neutral ph level. Condensate Drain & Overflow At the rear of the cabinet, on the control enclosure end, there is a 25mm diameter stainless tube. This is the condensate drain, which takes water away from the inside floor of the cabinet. A P trap drain is supplied and needs to be fitted. This P trap drain also connects to the Humidifier drain. Light Loft Ventilation. Two 300mm-diameter spigot s are provided on top of the chamber, so that the hot air exhausted from the light loft can be directed out of the building, using flexible circular duct. The inlet to the light loft is the spigot with the removable filter. The inlet filter should be cleaned at regular intervals. If they become blocked, a safety thermostat located in the loft air stream will turn off the lamps. Thermoline High Light Intensity Plant Growth Cabinets. The Thermoline High Light Intensity Plant Growth Chamber has been designed to provide a controlled environment of temperature, humidity, and lighting, to simulate growth conditions. Limitations of the cabinet are as follows, Temperature Humidity Co2 Lighting 5.0ºC to 45.0ºC 20%RH to 90%RH (Temperature Dependant) Ambient plus 50PPM to 3000PPM. (Optional) Up to 1000µmols (Approx.) at 1 Metre from light source. Theory of Operation. The plant growth chamber can be regarded as comprising of five main areas; these are as follows, Main growth area (workspace). Conditioning area. Light loft area. Control enclosure area. Sensor Housing Main growth area. Conditioned air (temperature and humidity controlled air) enters the growth area vertically, through a series of slots in the floor panels. The floor panels are made from stainless steel to prevent corrosion, and are fabricated in the shape of a Top-Hat section for strength. The floor can be adjusted in height using the Crank Arm at the front and rear of the cabinet. (See Paragraph Operating Guidelines for a Hydraulic Adjustable Shelf). 5
Conditioning area. Once the air has passed through the growth area, it returns to the conditioning area, through the return air panel at the top of the Main Growth area. This area contains the following components that are used to maintain the set temperature and humidity of the air: The cooling evaporator coil. The dehumidifying evaporator coil. The humidifier inlet. The air heating elements. The circulating fans. Air passes over each of the various components to be either heated or cooled, and to be either humidified or dehumidified. The air is then returned to the growth area by the circulating fans for the whole cycle to begin again. Four centrifugal fan wheels provide air circulation. These wheels are driven by externally mounted motors, which are inside the control enclosure. Air from the fans is forced into the sub-floor area this has the effect of pressurising the area below floor level, to enable the air to enter the growth area at an even rate. Light loft area. This area is separated from the main growth area by two layers of glass. Cool air is drawn into the light loft fan area through the air inlet filter on the end of the cabinet, over the discharge lamps control gear, by a centrifugal fan deck. The air is then forced through the light loft area, across the lamps, and is then exhausted to atmosphere through a spigot on the top of the cabinet. Eight high intensity, High Pressure Sodium, discharge lamps, plus eight-halogen globes provide lighting. HID 1. 4 x 1000 watt HPS lamps. (Lamps 1, 4, 5 & 8) HID 2. 2 x 1000 watt HPS lamps. (Lamps 3 & 7) HID 3. 2 x 1000 watt HPS lamps. (Lamps 2 & 6) Incandescent. 8 x 100 watt incandescent/halogen lamps. For lamp configuration see drawing at the rear of this manual. The lamps can be easily changed, with access through the hinged doors on both sides of the light loft. Model No of High Pressure Sodium Lamps: GE Lighting LU 1000/110/T/40. Alternate Metal Halide Lamp: Osram HQI-T-1000/D. GE Lighting SPL-1000 Controls enclosure area. This area contains the following, Operators control panel. (Mounted on the front) Electrical control panel. Humidifier steam generator. Refrigeration compressor, pressure controls, solenoids, etc. Miscellaneous other controls (water solenoids, etc.) Sensor Housing. Inside the 'Main Workspace' you will notice a stainless steel box hanging form the centre of the cabinet. This box contains the temperature and humidity sensor and a small aspirating fan. When the cabinet is running and controlling the set temperature and humidity, it is very important that the 'Sensor Box' is adjusted up or down to be in close proximity to the plant material. This way the controlled temperature and humidity will most resemble the location of the Plant Material. 6
Safety Controls and Interlocks There are a number of safety controls fitted to Thermoline Plant Growth Chambers, some of which are available to the operator and others, which are factory preset, as follows. High Temperature Safety This Safety is incorporated into the STAR-700 Touchscreen Controller. It is set so that if the Actual Temperature deviates the Safe Operating Value (SOV) or the Programmed Set Value (PSV) by more than 5.0degC then all sources of heating will be isolated. This includes the Lights. Low Temperature Safety This Safety is incorporated into the STAR-700 Touchscreen Controller. It is set so that if the Actual Temperature deviates the Safe Operating Value (SOV) or the Programmed Set Value (PSV) by less than 5.0degC then all sources of cooling will be isolated. As the cooling is isolated to protect Plant Material from Frost burn it also means that there is no form of heat removal, so the lights are also isolated. Element Safety Thermostat. (Not operator adjustable). This thermostat measures the air temperature adjacent to the air heating elements. If aircirculating fans fail or airflow is impaired by the placement of samples, this thermostat prevents the element from overheating. Light Loft Safety Thermostat. (Not operator adjustable). This thermostat measures the air temperature in the light loft. If there is a loft ventilation fan failure or if a dirty inlet filter or a blockage impairs airflow through the loft and lamp control gear, it will turn the lights off until the area cools down. Humidifier Safety Thermostat (not operator adjustable). This thermostat measures the temperature adjacent to the heating elements in the humidifier (steam generator). If there is an interruption to water supply (and level interlock fails), this thermostat switches off the heating elements and they remain switched off until it is manually reset. Water Level Interlock. The humidifier tank is fitted with two float switches. The upper level float switch operates a solenoid valve in the water supply, to maintain a constant level in the humidifier supply tank. The lower level float switch is interlocked with the humidity control circuit, such that if the water level falls below this float switch, power to the heating elements is switched off. If the humidity function is turned on and the water level falls below the lower float switch, the Humid Off indicator will illuminate. Electrical Circuit Breakers. These circuit breakers protect the electrical system against major damage from electrical faults. If they are tripped for any reason, determine the cause and rectify the fault before resetting. Refrigeration High & Low Pressure Safety. (Not operator adjustable) This pressure switch shuts down the refrigeration system if the refrigerant pressure is above or below the compressor s operating range. 7
Crankcase Pressure Regulator. (Not operator adjustable). This mechanical regulating device has two functions and are as follows, 1. It prevents the pressure of the refrigerant gas returning to the compressor from rising above its stated tolerance. 2. It provides some degree of refrigeration capacity regulation to balance the heating and cooling systems. Head Pressure Control. (Not operator adjustable) This pressure switch operates the fan on the refrigeration condenser, to maintain the refrigerant pressure when the surrounding ambient air temperature is appreciably lower than the internal chamber operating temperature. Compressor Liquid Injection Thermostat. The temperature sensor of this device is attached to the refrigerant line returning to the compressor. If the temperature of this line becomes hot, because of a high chamber temperature or a long period of system bypass, liquid refrigerant is injected into this suction line to cool the gas returning to the compressor. Alarm Indicators. Inside the electrical enclosure on the main component board are some indictsing lights. These lights indicate the following conditions High Pressure Safety: Low Pressure Safety: Thermal Overload Loft Safety Humid Trip Safety: Indicates a High Pressure occurrence within the Refrigeration system. This is a manual resetting device. If it continually trips seek advice from a qualified Refrigeration Technician. Indicates a Low Pressure occurrence within the Refrigeration system. This is a manual resetting device. If it continually trips seek advice from a qualified Refrigeration Technician. Indicates that the Compressor has had an overcurrent situation. If it continually trips seek advice from a qualified Refrigeration Technician. Indicates a high temperature situation within the light loft. Usually indication that the Light Loft Fan has failed. This indicates an over temperature occurrence within the Humidifier Tank. This is a manually resetting device. 8
Safe Operating Value (SOV). STAR-700 TOUCHSCREEN OPERATING GUIDELINES. On initial Power up the STAR-700 Touchscreen shows the Screen Saver page. See Below Image. On Initial power up cabinet controls the Safe Operating Value only. The Touchscreen is fitted with a Security Screensaver to stop unauthorised access to the controlling parameters. This Security Screensaver becomes active if the Touchscreen has not been touched for more than 5minutes or if power is cycled. To exit out of the Security Screensaver simply press the Press to Log In & Exit Screensaver Button. The User Access window will appear. To exit out of the Security Screensaver and enter into the Main Menu Screen use the following passcodes: User Number: 1 Passcodes: 1111 These passcode should only be given to Authorised Personnel. To enter the User Number and/or the Passcode simply press the Numeric Window and the Numeric Keyboard will be displayed. Simply enter the User Number and/or the Password and press enter. Once you have pressed enter press the screen anywhere above the Login Button and the Main Menu screen will appear. When in the Main Menu Screen you will notice that the indicator in the top right corner states that the Diurnal/Program Cycle is Off. The Values below the heading Safe Operating Value are the current set values and the controller will start to control these values. During Safe Operating Value control, the Lights can only be manually operated by using the drop down menu underneath the heading Lights (SOV). The Lights SOV is a manual operation of the Lights, in the ON mode they are continually on and in the OFF mode they are continually off. To operate the Lights on a Diurnal/Program Cycle the operator will need set up the Diurnal/Program Cycle. To change the Safe Operating Value simply touch the Operating Value box. A popup numeric keypad is displayed. Type in the new value and press enter. The cabinet will automatically control the new Safe Operating Value. The Safe Operating Value has been designed to be set by the operator to a safe condition that will not cause damage to any of the Research, Experimental and/or Plant Material within the cabinet, in the event of a power failure. If the controller is operating in Diurnal/Program Cycle mode and there is a power failure, on resumption of power the Diurnal/Program Cycle mode will stop and the cabinet will be controlled at the Safe Operating Value.

Program/Diurnal Set-Up. The STAR 700 has a 250 segment Programmer. The 250 segments are split between 25 Programs (10 Segments per program). The Program Set-Up is securely protected by means of a user name and password. By pressing the Thermoline Logo the Login Screen appears. The Username is 02 and the Password is 2222. Once the Password is entered the next touch of the screen needs to be the Program Set-Up button. If the screen is touch anywhere but the Program Set-Up button the password will be reset and will need to be re-entered. Once the Program Set-Up button has been pressed then the Program Set-Up screen is displayed. Main Screen with Login Screen showing Login Screen Diurnal/Program Set Up Screen. The above screen shows the Program set-up page. This consists of 25 programs having a total of 250segments (10segments per program). Program 1: Segments 1-10 Program 2: Segments 11-20 Program 3: Segments 21-30 Program 4: Segments 31-40 (etc) Program 25: Segments 241-250. 11
Each program can be set as an independent program or can be linked to create one large or multiple large programs. This is achieved by not using an End segment in a particular program. For example if your program requires the use of 15 segments we can use the 10 segments of Program 1 and the first 5 segments of Program 2 making Segment 15 (5 th Segment of Program 2) an End Segment type. We would then start program 1 and as the program runs through the first 10 segments of program 1 and because there is no end segment in Program 1 it continues to run program 2 until it find the end segment at segment 15. When linking multiple Programs, to use more than 10 segments, the programs need to be sequential. By pressing on Program 1 the following screen is displayed. The below example is a Diurnal cycle of 40degC and 40% day and 10degC and 80% Night. Assuming that 40degC is at midday this program has been written to start at 25degC and 60%RH assuming that the day condition of 40degC and 40%RH is Midday then this program would need to be started by the operator at 6am. Program 1 Segment 1-5 Program 1 Segment 6-10 12
The following is a description of what each of the items in the Program are and what function they perform. Segment Type: Jump To: Jump Cycle: Temperature: Humidity: Co2: Hours: Minutes: Seconds: End Action: G Soak Temp The segment type can either be a Time, Jump To, or End type. Time: This determines that the segment is a period of time. The time is set in Hours, Minutes and Seconds. Jump To: This allows the program to repeat a predetermined set of segments. By selecting the Jump To parameter in segment type and then entering a segment value at the Jump To parameter, will tell the program were to jump back to. At Jump Cycle enter how many times it jumps back to or repeats the predetermined set of segments. See Example on next page. End: This tells the program when to end. There has to be an end segment. Failure to enter an end segment will cause the controller to indefinitely dwell at the last segment. The operator would enter the segment number that the program will jump back to. This value is ignored if the segment is set to either a Time or End Segment. The operator would enter a value here as to how many times the Jump To repeats itself. A value of 0 will continually repeat the Jump To segments until the operator ends the Program Cycle manually. This value is ignored if the Segment Type is set to either a Time or End Segment. The operator would enter the Temperature they require the cabinet to achieve. This value is ignored if the segment s Step Type is Jump To. The operator would enter the Humidity they require the cabinet to achieve. This value is ignored if the segment s Step Type is Jump To. The operator would enter the Co2 they require the cabinet to achieve. This value is ignored if the segment s Step Type is Jump To. The operator would enter the required length of time for the segment in Hours. This value is ignored if the segment Step Type is set to either Jump To or End. The operator would enter the required length of time for the segment in Minutes. This value is ignored if the segment Step Type is set to either Jump To or End. The operator would enter the required length of time for the segment in Seconds. This value is ignored if the segment Step Type is set to either Jump To or End. This value determines what will happen when the program ends. It can be set to SOV, which stops the program from operating and controls the Safe Operating Values. Or it can be set to dwell, in which case it will continue to control the Temperature, Humidity and Co2 of the last Time segment. This is the Guaranteed Soak Parameter and is only visible if the Guaranteed Soak is enabled. This parameter is generally not used on the Climatron range of Plant Growth Cabinets as it can extend the time of a Diurnal Program effectively making the Diurnal Cycle longer than 24hours. The Guaranteed Soak allows the Program to maintain its Programmed Temperature Value for the duration of the Segment Time by automatically placing the Program into a holding pattern and not allowing the program to proceed if the Actual Temperature Value deviates the Programmed Temperature Value by a predetermined value. Once the Actual Temperature Value is within the predetermine range then the Program will automatically continue. 13
G Soak Humidity G Soak CO 2 This is the Guaranteed Soak Parameter and is only visible if the Guaranteed Soak is enabled. This parameter is generally not used on the Climatron range of Plant Growth Cabinets as it can extend the time of a Diurnal Program effectively making the Diurnal Cycle longer than 24hours. The Guaranteed Soak allows the Program to maintain its Programmed Humidity Value for the duration of the Segment Time by automatically placing the Program into a holding pattern and not allowing the program to proceed if the Actual Humidity Value deviates the Programmed Humidity Value by a predetermined value. Once the Actual Humidity Value is within the predetermine range then the Program will automatically continue. This is the Guaranteed Soak Parameter and is only visible if the Guaranteed Soak is enabled. This parameter is generally not used on the Climatron range of Plant Growth Cabinets as it can extend the time of a Diurnal Program effectively making the Diurnal Cycle longer than 24hours. The Guaranteed Soak allows the Program to maintain its Programmed CO 2 Value for the duration of the Segment Time by automatically placing the Program into a holding pattern and not allowing the program to proceed if the Actual CO 2 Value deviates the Programmed CO 2 Value by a predetermined value. Once the Actual CO 2 Value is within the predetermine range then the Program will automatically continue. Lighting/Event Outputs. At each segment page there is a Lighting/Events button. By pressing this button the display shows Eight events that can be turned ON and OFF for each segment. The First Event which is generally labelled Lights is what turns the lights ON and/or Off. A total number of Eight Lighting/Event Outputs are available, however only the required hardware is fitted per cabinet. Program 1 Lighting/Event Segment 1-5 14
Program 1 Lighting/Event Segment 6-10 Program Features. There are a few other features of the program that cannot be changed but are described below. Guaranteed Soak: This is a tolerance value, set at +/-2.0degC, and guarantees that the Program Set Values for Temperature only are reached. If during a program cycle the Actual Temperature deviates the Program Set Value (PSV) by more than +/-2.0degC the program will be put into a hold mode until the Actual Temperature is within the PSV. There is no Guaranteed Soak on the Humidity Value or the Co2 value. These values can deviate without the program going into a hold mode. Program Start Value: The Program starts at whatever the Actual Temperature, Humidity and Co2 are. If when starting the program the Actual Temperature is more than +/-2.0degC from Segment 1 s PSV the Guaranteed Soak value will hold the program until it reaches Segment 1 s target temperature. Power Failure: In the event of a power failure the Program Cycle will end. On resumption of power the cabinet will control the Safe Operating Values. 15
Starting the Diurnal/Program. The following screen shows the Diurnal/Program Set-Up screen. Once the desired program has been set up then the operator will need to enter the desired program number value into Start Program Number. Once the desire value has been entered the operator can then start the program by using the drop down menu. The following describes the item and the function of the parameters in the drop down menu. End The end parameter is what stops a current running program from operating Start The Start parameter is what starts the program that is entered into the Start Program Number. Pause The Pause Parameter will simply pause the program at its present point. It will hold this point until the resume parameters is selected. If the Start parameter is selected while a program is in pause it can restart the program from the beginning. Resume The Resume parameter will resume a program after it has been paused. Diurnal/Program Set Up Screen. Note: The Program can be Started, Stopped, Paused and Resumed in the Main Menu Screen. However you cannot select the Program Number in the Main Menu Screen. When the program is operating the Start Program Number value disappears and the Program Number Running value appears. The Program Running Number is a read only value just to give the operator and understanding of which program is operating. To change the Program that is running the operator will need to End the program to change the Start Program Number. This can only be performed in the Program Set-Up page. 16

This screen is for the sole purpose of our service technicians or service contractors. This is a password protected screen and is only accessible by authorised Thermoline Technicians or Authorised Thermoline Contract Technicians. 24
Diagnostics Screen. The Diagnostics screen is simply a screen to help the operator when problems may occur. For example if the STAR-700 is operating a Program Cycle and there is a cycle of Power, the STAR-700 usually reverts back to SOV mode. However as power loss may occur due to storms and lighting strike and possibly construction work, the disruptive power supply may cause interference with the communication cable and cause the STAR-700 Controller to turn the control actions for Temperature, Humidity and CO 2 Off. The Diagnostic screen allows the Authorised operator to turn the Temperature, Humidity and CO 2 functions back on again. It also shows the percentage output of each control function. This is a good diagnostic tool if the cabinet is not operating correctly. Diagnostic Screen. Contact Screen The Image Below is the Thermoline Contact Page. Contact Screen. Service Screen.

Regular Checks and Maintenance. Owing to the conditions under which the chamber will operate, some regular checks need to be performed, as follows, The humidifier is continuously evaporating water to produce steamer humidity control. This will leave behind deposits of mineral salts inside the tank, which will eventually form a crust around the elements and may cause premature failure of the elements. It is important that the tank is flushed regularly to reduce this effect. A drain valve is fitted to the humidifier tank to allow it to be emptied. With the power turned off open this valve to drain the tank, and then close it before turning on the power. The water will automatically fill the tank with fresh water. The frequency of this action will depend upon the type of water used and the temperature and humidity conditions set for the plant growth chamber. No water should be allowed to build up in the base of the chamber (below the floors). The floor drain should be checked regularly for blockages. The air intake filter for the light loft should be cleaned regularly, to stop a build up of dust on the light loft glass. Failure to clean this filter could also result in a reduced flow of cool air across the lights, and a subsequent shutdown of the lights because of lack of ventilation. The filter simply pulls out of the intake vent located on the roof above the electrical controls enclosure on the end of the cabinet. Light intensities should be checked with a light meter, and lamps replaced if necessary. The glass between the loft area and the growth area may need cleaning occasionally, as dust build-up will reduce light intensity. The high intensity discharge lights are High Pressure Sodium Lamps: GE Lighting LU 1000/110/T/40. Alternate Metal Halide Lamp: Osram HQI-T-1000/D. GE Lighting SPL- 1000. Intensity at delivery time is nominally 1000µmol/m²/sec. at 1 metre down from lamps (all lamps on) As the refrigeration runs continuously, there is a constant airflow being drawn through the Remote Air Cooled Condenser. Make sure that the Remote Air Cooled Condenser is check and cleaned at regular intervals. It is most important that a regular check of the state of the condenser is performed and any build up of material, which would impair airflow, removed. 26

Operating Guidelines for a Hydraulic Adjustable Shelf. The Thermoline Plant Growth Cabinet has been fitted with a Hydraulic Adjustable Shelf/Floor System. This enables the operator to adjust the height of the shelf by 400mm without the need to remove plants or open the door. Shelf/Floor Adjustment. To adjust the shelves simply turn the Shelf Adjustment Arm. A clockwise rotation will raise the shelf and anti-clockwise will lower the shelf. The Hydraulic adjustment allows for 400mm of adjustment without the need to open the doors or remove any Plant s. If more than 400mm of adjustment is needed then the Plant s will need to be removed from the cabinet and the Stainless Steel floor removed. Once the Floor has been removed the Front and Back Floor supports can be removed and raised to the next support level. There are 3 support levels at 300mm centres. This allows for a total of 1000mm of shelf adjustment within the cabinet (See Photos at the end of this document). Please note that the Floor Supports are front and back specific. The Front Support has two blanking plenums that fit between the access doors. This is to prevent the air circulation from short cycling. When adjusting the Shelf Height in an anti-clockwise direction (Lowering the Shelf) you may find that the shelf is not lowering at the same rate at which you are adjusting the arm. This is due to the Hydraulic oil slowly purging back in to the Purge cylinder. Do not be concerned as it will eventually catch up. This will be less noticeable when loaded with plants as the weight helps with the purge of oil. When adjusting the shelf in a clockwise direction (Raising the Shelf) please take great care not to allow the product on the shelf to touch the Glass Roof. Any hard or sharp items could cause the glass to break. As the hydraulic oil in the shelf system is affected by Temperature, you will notice movement of the shelf height. The shelf height will move between 10-15 mm throughout the 5.0degC to 45.0degC range. Loading the Shelf/Floor. When placing Plant on the floor please load the plant in an even and uniform manner determined by weight not volume. The reason for this is that the four hydraulic rams are connected to one common plunge cylinder. If the Plants are placed unevenly by weight you will find that the floor may not be level. Do not overload the floor. The maximum Total weight that the Hydraulic Shelf system can hold is 300kg. Do not exceed this limit. 28
