5 Health and Safety This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance..0 HOW THE CALOREX SERIES 3 VARIHEAT SYSTEM WORKS. The Calorex SERIES 3 VARIHEAT range consists of models: 600/900/00/500. The model number increases in relation to the recirculated air flow from model 600 at 000 m³/h to model 500 at 300 m³/h. 600 and 900 models are fitted with constant flow fans and deliver the optimum airflow, self compensating for pressure differentials in the system. All models are fitted with either one or two console fixing service panels These allow for the console to be fixed to the Variheat 3. These service panels can be fitted on any face of the machine. When optional fresh air box is fitted, all models have the facility to exhaust a percentage of the recirculating air and introduce a slightly lesser amount of fresh air (slight differential creates a negative pressure on pool hall to localise pool environment and protect the building fabric). An optional negative pressure box is also available. This exhausts a percentage of the circulating air without introducing fresh air to the pool hall. Optional, factory fitted frost protection kits are available, for use when the fresh air box is fitted. These kits protect the LPHW from freezing by closing the dampers to min when the ambient temperature is below 6ºC. The first kit controls the machine dampers. A second kit controls the machine dampers and also a remote damper fitted by the customer in the installation ductwork. All AW models are fitted with a fully controlled low pressure hot water air heating battery and a pool water heat exchanger. Provision is made for an external heat source to be initiated by the SERIES 3 VARIHEAT controller. All AW models have air and water heat exchangers recovering energy from the refrigerated dehumidification process. These are also fully controlled with priority given to water. Page 3 SD37360 SUE

6 THE CALOREX SERIES 3 VARIHEAT RANGE. FEATURES :- All versions have removable drip trays for easy cleaning. Control panel can be mounted remotely up to a maximum of 0 metre cable length. Models fitted with a fresh air box or a negative pressure box have motor driven louvres on the exhaust and fresh air dampers. Optional electrical resistance air heater boxes ranging from 6kW to 8kW. The power to each model in the range is fed in via din rail mounted terminal blocks located in the electric box of the unit. CONTROL PANEL. (All Models) Note AA Models do not have a water temperature controller, and do not include a time clock unless fitted with LPHW. The panel has the following features,. Relative Humidity Controller, with red light to indicate dehumidification demand.. Air Temperature Controller, with red light to indicate air heating demand. 3. Water Temperature Controller, with red light to indicator water heating demand.. Fresh Air Switch, with MAX, AUTO and MIN positions (for use with fresh air module or negative pressure box). 5. Economy Switch to select between water heating only or full function on AW versions. 6. On/Off Switch. TE with the switch in the OFF position the machine is still live and mains lamp and clock are energised. 7. Air/Water switch, can be set to give priority to either water heating or air heating. 8. Time clock to control occupied/unoccupied timings with battery back up and manual override. 9. Indicator lights :- Power on Fault Defrost Auto Dehumidification Air heating Water heating (if applicable).

7 . OPERATION When the SERIES 3 VARIHEAT is connected to the mains supply via an isolator and the isolator is energised, the MAINS light on the side of the electric box will illuminate indicating mains ON and time clock will start to run. The time clock has a battery reserve fitted which when charged will run for 00 hours so that isolating the machine for short periods will not affect the time clock settings. The SERIES 3 VARIHEAT unit is switched on to normal operation by an ON (I)/OFF (O) switch on the control panel. When switched on the red indicator light will illuminate and digital controllers will light up. Note digital water controller will be the only controller to light up when in economy mode. Providing that the controls are set to the correct parameters; nominally 60% RH, 8ºC air temperature, 6ºC water temperature and fresh air switch set to AUTO, then the machine will operate automatically. The unoccupied temperature is set on the digital air controller and will be switched at the time set on the time clock. As the unit operates, the indicator lights will show the state of the control conditions, ie dehumidification, heat to air and heat to water. Other indicator lights are :- Yellow for Fault (high or low refrigerant trip or soft start fault if fitted). Yellow for Defrost Green to indicate automatic operation. See section 3.0 for control panel symbols. PARAMETER CONTROLLERS Each parameter, Relative Humidity, Water Temperature and Air Temperature is sensed within the machine and the signal is taken to the relevant digital controller. RH & Water Temperature controllers have two switching channels, also the Air Temperature controller for AA units without room heating: OUT which is set from the front panel, OUT which is factory pre-set. The Air Temperature digital controller for units with room heating has three switching channels, one of which is for setting OCCUPIED/UCCUPIED air temperature. Each channel has a switching differential which is also factory pre-set. None of the factory settings should be tampered with. When the re-settable channel is adjusted all other settings and differentials automatically follow at the correct relationship. Nominal set point values & diffs RH% = 60% diff 3% Air temperature = 8ºC diff 0.5 ºC Water temperature = 6ºC diff 0. ºC Please note: on AA machines with no fresh air box or RCU, in occupied mode dehumidification stops once the Air temperature is.5ºc above set point. TIME CLOCK The time clock setting determines the OCCUPIED/UCCUPIED periods and is set to match the operators requirements regarding opening and closing times for the pool and possible times where the pool is covered. The two settings are OCCUPIED or day time, and UCCUPIED or night time (covered). The most obvious action of this change is to lower the pool hall air temperature to a determined level to conserve air heating energy. This lowering of temperature is allowable because of the quiescent, and ideally covered, condition of the pool. Pool water occupied = (no pool cover) Pool water unoccupied O = (pool covered) Page 5 SD37360 SUE

12 . PLUMBING POOL WATER The Calorex SERIES 3 VARIHEAT should be connected as shown in section 3.0. If an existing heater is being retained then the VARIHEAT should be connected between the filter and the existing heater. Pool water connections on the machine are BSPM stubs. The unit is supplied with off each of the following PVC fittings - BSPFx M F x ½ M ½ x 50mm F Suitable breakable couplings, isolation, and drain down valves should be installed in the pool water inlet/outlet pipes local to VARIHEAT unit. The heat exchanger in the VARIHEAT unit will, on small pools, take the full flow rate of the recirculation system. On larger pools a bypass or separate auxiliary pump may be necessary. This method can also be used to reduce energy consumption, by the installation of a two speed or auxiliary pump by-passing the main pump/filter to satisfy pool water heating and dehumidification without the need for the main pump to be running. When the pipework installation is complete the circulating pump should be switched on and the system checked for leaks. Also check the filter gauge to see that there is not excessive back pressure. CONDENSATE DRAIN The condensate driptray in the VARIHEAT unit collects the water removed by the dehumidification process, It is therefore necessary to ensure that the VARIHEAT unit is placed on a level plinth so that the condensate can run away and not overflow the edges of the driptray inside the machine. All SERIES 3 VARIHEATS have a 3/ BSPM threaded condensate drain connection. The drain pipe should run away with adequate fall to waste ie / per foot min. and must incorporate a U trap & tun dish. BOILER PLUMBING The boiler connections on the machine are :- 3/ BSPM on AW600/900 BSPM on AW00/500 for connecting the boiler water flow and return. Suitable breakable couplings, isolation, and drain down valves should be installed in the boiler water flow and return pipes local to the VARIHEAT unit. Water and air LPHW circuits internal to Calorex Heat Pump should be bled for air pockets. (Bleed valves fitted to unit). Refer to the boiler manufacturers instructions before designing the pipework system. IMPORTANT GENERAL CONDITIONS. Do not route water pipes across service access panels or air inlet/outlets.. The water circuits to and from the VARIHEAT unit should be capable of maintaining the specified water flow limits required by the machine. 3. All pipe work must be adequately supported with allowance for expansion and contraction especially with regard to the plastic pipe work.. It is recommended that when installing water systems the last connections to be made should be adjacent to the VARIHEAT unit to avoid undue stresses on the unit connections. 5. All pool purifying devices and chemical injection systems must be fitted down stream of the VARIHEAT unit with a non-return valve to prevent concentrated chemicals back feeding into the heat exchangers. 6. The practice of dosing chemicals direct into skimmer basket must not be allowed as this would result in concentrated corrosive liquids passing over vulnerable metal components. 7. Water quality must be maintained not only relating to solids, etc but for ph between , and if pool water is saline at a maximum concentration of 8mg/litre. 8. See Warranty Exclusions section 6.0 for total list of water quality limits. Page 0 SD37350 SUE

13 . DETERMINING WATER FLOW Flow Meter Method (see pool water schematics) Ensure isolation valves A and B and bypass valve C are fully open. Slowly close down bypass valve C until correct flow rate is shown on the flow meter (see section.0). Remove handle and lock off valve C. Differential Pressure Method By simply installing two filter pressure indicating gauges, one on the inlet and one on the outlet of the heat pump, and a locking type gate bypass valve in the bypass line, the flow rate through the heat pump can be accurately determined by the difference in the readings of the gauges. This pressure drop is proportional to flow. Flow rate should be set at the maximum differential with a clean filter fitted, this differential pressure will drop as the filter becomes dirty. Provided the filter is cleaned before the minimum differential is reached then no problems should be encountered (standard system only) Setting up the differential When the installation is complete, the procedure for setting the flow rate through the heat pump using two gauges is as follows :-. With the heat pump switched off, ensure isolation valves A, B and bypass valve C are fully open.. Switch on water circulating pump. 3. Note the water system pressure on both gauges - they should read the same, but because of manufacturing tolerance they may read different. For example :- with a water system pressure of 5mhd the gauge on the inlet may read 5 and the outlet gauge 5.5 therefore there is a static error difference of 0.5mhd.. Gradually close the bypass valve C until there is a difference in pressure between the two gauges that is equal to the required pressure drop (see section.0) observing any static error on the gauges before beginning this process. 5. Lock the bypass valve, or render it tamper proof when correct setting is achieved. 6. See section.0 for correct pool water pressure drop. Page SD37360 SUE

16 . ELECTROLYTIC CORROSION IN SWIMMING POOLS Electrolytic corrosion will occur when dissimilar metals that are in contact with each other create a potential difference between themselves. Sometimes separated by a conductive substance known as an electrolyte, the dissimilar metals will create a small voltage (potential difference) that allows the ions of one material to pass to the other. Just like a battery, ions will pass from the most positive material to the more negative material. Anything more than 0.3 volts can cause the most positive material to degrade. A swimming pool with its associated equipment can create this effect. The pool water being an ideal electrolyte and components of the filtration circuit, heating system, steps, lights etc providing the dissimilar metals needed to complete the circuit. Whilst these small voltages are rarely a safety threat, they can create premature failure through corrosion. Not dissimilar to corrosion through oxidation, electrolytic corrosion can cause complete failure of a metallic material in a very short period of time. In order to prevent this type of corrosion all metallic components in contact with swimming pool water should be bonded together using 0mm² bonding cable. This includes non-electrical items such as metal filters, pump strainer boxes, heat exchangers, steps and handrails. It is highly recommended that bonding be retrofitted to existing pools, which may not be protected by this system. Page SD37350 SUE

17 .5 ELECTRICAL INSTALLATION ELECTRICAL SAFETY It is important to ensure that all aspects of the installation comply with the latest I.E.E. Regulations. It is also important to ensure that any remote devices which terminate within the pool hall are of the type and voltage as specified in the latest I.E.E. Regulations. The machine should be installed in accordance with EMC00/08/EC. PROTECTED SUPPLY Whilst not mandatory, Calorex recommend that an R.C.C.B. is always fitted or that the supply is to local electricity authority recommendations, and that all ducting is bonded in accordance with these regulations. The supply to the machine should incorporate fuses or motor rated circuit breakers (type GU, FAZC) to specified rating (see data sheet) H.R.C. fuses are recommended. An isolator must be fitted within clear view of the machine and not more than metres away. The isolator must have a minimum of 3mm air gap when in the off position. INCONSTENT ELECTRICAL SUPPLY. The following limits of operation must not be exceeded if Calorex machines are to be guaranteed either in performance or warranty terms :- Voltage single phase - 07V min, 53V max Voltage three phase - 360V min, 0V max Frequency - 7.5Hz min, 5.5Hz max. N.B The voltage must be measured at the heat pump mains terminals with all the fans/compressors running at the rated condition. Please note that AW00/500 three phase machines are fitted with a phase rotation relay and will not run if the phases are connected incorrectly or if the voltage is 5% less than 00V (30V) for a three phase 50Hz machine CORRECT CABLE SIZING The cable supplying electricity to a machine with a given load must increase in cross sectional area (CSA) as the length increases in order that the voltage drop within the cable does not exceed recommended limits. Cable sizing should be calculated by an approved electrician with due consideration to I.E.E. and local codes of practice. If resistance heaters are fitted an extra power supply will be required to the terminal blocks inside the heater box, see data sheet for supply amps and fuse size.

19 .5. TES ON TERMINAL BLOCK CONNECTIONS TE - Remote occupied/unoccupied These contacts (from terminals 0 & ) are to enable the air temperature set back facility to be remotely overridden. Please note that in unoccupied mode on AW machines, water heating does not take place unless there is a demand for dehumidification. There is a Vac output from these terminals and closing a remote switch will enable the unit to regain the normal operating air temperature for when the pool is in use. This can be done via a voltage free pool cover switch or some other form of voltage free switch. If this facility is used then the time clock (if fitted) on the control panel of the unit should be set to the unoccupied (o) position. (See note on time clock and switch settings, section 3..). If these terminals are fitted on versions without time clocks then they MUST BE LINKED. TE - Pool pump start -AW only (see also section 3..) These are voltage free contacts (from terminals 8 & 9) rated at 3() Amp at 30 Volts. If the pool water pump is to be run via an external time clock then these connections should go across the switching contacts of the external time clock to ensure that, if dehumidification demand occurs the pool water pump will start. The pool water pump will exceed the one amp inductive rated current of these contacts therefore a contactor or relay should be used to switch the load of the pump.the switching action of the external time clock should energise the contactor/relay coil. If the pool water pump is to be run continuously then these contacts can be ignored. TE 3 - Boiler demand -AA+LPHW & AW machines only These are voltage free contacts (from terminals 6 & 7) rated at 3() Amp at 30 Volts. If the low pressure hot water supply to the unit is to be governed by the Calorex unit then these contacts should be utilised to bring water to the unit via the boiler, motorised valve, boiler pump etc. Remember the maximum inductive load is one amp. This is dependant on how the low pressure hot water supply to the unit has been designed. If the supply of low pressure hot water to the unit is not dependant on a signal from the unit then these contacts can be ignored. TE SEPARATE SUPPLY FOR RESTANCE HEATER BOX If resistance heaters are fitted then an extra power supply will be required to the terminal blocks inside the heater box. See section.0 for supply amps & fuse size. CONTROL PANEL 5 WAY CABLE CONNECTION Data signal between control panel and electric box is via a 5 way cable with D connection (plug & socket) both ends.

29 COMMSIONING CHECKLT a. Is the building finished in accordance with the original plans and specification. b. Is the plenum chamber and all ductwork insulated, special attention should be made to the insulation of the exhaust air ducting and fresh air inlet ducting to prevent condensation problems. c. Are there any significant draughts in the pool hall or plant room (plenum installation) through poorly fitting doors, windows, pipe ducts, etc. This will let in unwanted ambient air raising the heating duty required. d. Is fresh air suction and exhaust air discharge ducting (if fitted) perfectly sealed from plant room. TE: (c) and (d) above should be checked by measuring plant room and pool hall air temperatures.if the plant room is acting as a plenum chamber both temperatures should correspond. If the plant room temperature is lower then ambient air is leaking in, this leak should be located and rectified. e. Are the fresh air inlet and exhaust air outlets free from obstructions ie, undersize grilles, objects in the path of exhaust air deflecting it back to the fresh air inlet, etc. f. Is occupied / unoccupied set correctly, (set with air thermostat) see section g. Is the time clock set correctly. h. Is start up ( fresh air flow switch to min ) feature required and if so is customer aware of when to switch machine back to Auto. i. Has the Calorex Heat Pump been bled for air pockets. (Bleed valves fitted to unit as standard). j. Any sign of abnormal operation such as water dripping should be reported immediately to an installer or Calorex. k. Is airflow sufficient through machine? Remove fan damper plates and check fan amps. l. Check belts and filters are fitted correctly TIME CLOCK SETTINGS The time clock is a quartz hour clock with 00 hours battery reserve used to control the automatic operation or the SERIES 3 VARIHEAT unit per hour time cycles. SETTING ACTUAL TIME Turn the large clock hand clockwise until the correct time of day is set, ensuring that the correct half of the day is chosen ( hour clock). 7 SEGMENTS 8 AUTOMATIC AND MANUAL SETTING LEVER 0 A FIG. SETTING FOR AUTOMATIC OCCUPIED/UCCUPIED OPERATION WITH TIME CLOCK To set for automatic time clock control of occupied/unoccupied, slide the lever to A. Each yellow segment represents a 5 minute time period. Extend outward the segments for a period of time that the pool is occupied (i.e. used or uncovered) per day. If the unoccupied period is more than 0 hours per day, extend one segment at 9:00 or other suitable time that does not coincide with the main occupied period*. Page 7 SD37360 SUE

30 SETTING FOR AUTOMATIC OCCUPIED/UCCUPIED OPERATION WITH REMOTE INTERFACE To set for remote control of occupied/unoccupied, slide lever to O. See section., Note for more information on remote interface. If the unoccupied period is more than 0 hours per day, extend one segment at 9:00 or other suitable time that does not coincide with the main occupied period.* Ensure all other segments are pushed inwards and slide lever to A. SETTING FOR MANUAL OCCUPIED/UCCUPIED OPERATION To set for manual occupied period (or override automatic unoccupied period) slide the lever to I for occupied. If the unoccupied period is more than 0 hour per day, to set for a manual unoccupied period slide the lever to O for unoccupied ; extend outwards one segment at 9:00 or other suitable time that does not coincide with the main occupied period* and ensure all other segments are pushed inwards. *In unoccupied mode, the pool water is not heated unless a demand for dehumidification occurs during this period. If the unoccupied is more than 0 hours per day, it is recommended to allow a brief occupied period to allow the water temperature to be sampled and maintained if necessary. 3..

Press down P, SP and Set Point value will be displayed alternately. Press the or key to change the value of SP. Once the desired value is displayed press P to memorise the value. The display will revert to the present reading. TE: If anything else shows on the display leave alone for minute until the display returns to normal. AIR TEMPERATURE DIGITAL CONTROLLER AW AND AA MACHINES WITH AIR HEATING The digital controller for controlling air temperature can be changed as follows:- To program the set point, press P button once and release it. SP (set point) and set point value e.g. 8 will be displayed alternately. Press P again AL (-.5) will show. This is the difference between the set point and AL plus a constant 0.5 e.g = ºC (unoccupied) SP and AL can be changed in the same way as described for humidity and air. TE: AL can only be set - to -0 below SP value. If the reading on the digital controller is not the same as the actual pool hall temperature, water temperature or relative humidity it may be necessary to program an offset into the digital controller.

When not energised and the machine is switched on allows the pool pump & water LPHW to operate in economy mode once 60 min timer on AW machine (if fitted) has timed out, when water temperature is below stage. R Energised when stage (unoccupied) or stage in occupied mode. Air heating is needed bring on the LPHW air valve or resistance heater (used on AA machine to bring on the fan if air is below stage. R has to be made in occupied mode). It will also bring on the fan on all machines if fan is not already running. R3 Energised when dehumidification is needed as long as LP and HP pressure switches are not in fault mode. R Energised when time clock is in occupied mode on AA+LPHW / resistance heating and AW machine. On AA with air box or RCU energised once the power switch is made. R5 Energised on humidity still rising above stage, which in turn will open the dampers (only if air box is fitted and R is energised). R6 Energised when damper switch on control panel is switched from auto mode (only if air box is fitted). R7 Energised to switch the air box to max (if air box is fitted). R8 Energised when water temperature is above stage it energise the reversing valve to send dehumidification heat to air (AW machine only). R9 Energised if LPHW water heating is required to start the pool pump only in the occupied mode and economy mode or if at any time dehumidification is happening (AW machine only). R0 Energised by relay 9 to bring on water LPHW valve. Only if water temperature is below stage in occupied mode only. (AW machine only). R Used on AA / AA+LPHW / resistance heating machine without options to stop dehumidification once air temperature is above stage on AA machine, above stage 3 on AA+LPHW / resistance heating. R Used only if RCU unit is fitted energised if air temperature is above stage on an AA machine with out time clock or stage 3 on all other machines. R3 Used only on AW machine to start LPHW water heating and pool pump if water temperature is below stage in the occupied mode only. R Provides volt free contacts for remote control power indication. RE Energised by R to bring on the fan when the fan is wired to cycle mode when air temperature is low. RE Energised in defrost mode to bring on defrost lamp and if RCU is fitted to change back to valve A if RCU is calling for, valve B when machine is in defrost mode. RE 3 Energised once R is made unless the soft start has a fault or soft start link is broken. Which would cause RE 3 to drop out bring on the fault lamp. RE Provides volt free contacts for fan running. Page 6 SD37360 SUE
