Page 1 1. PRINCIPLE OF OPERATION. The dehumidifier removes water from an airflow through, and the removed water is carried away from the dehumidifier with the regeneration air (henceforward called reg.-air). Water adsorption and -extraction takes place in a rotor made of water resistant silica gel. The air flows in the dehumidifier divides the rotor in two parts : drying part and reg.-part. Two separate air flows passes through the rotor: - the process air passes the drying part, which is 75% of the rotor material. In the rotor, part of the water content is adsorped and the air leaves the rotor as dry air - the reg.-air is a closed circuit: - in the electric heater it is heated to app. 100C - passing the reg.section of the rotor (25% of the rotormaterial) the energy is used for evaporating the adsorped water, which is then carried out of the rotor - the air is then cooled in the heat exchanger and the water will condensate and leave the dehumidifier as free water. The two air flows are fixed and the rotor turns - this gives an automatic process of simultaneous water adsorption and water extraction (see principle of operation, drawing R1213 page 2). The heat exchanger is cooled by the cooling air, which has common inlet with the process air (see principle, fig. 1, page 2). CAPACITY.

This is caused by the evaporation heat release and heat gain from the rotor. The temperature is shown to be 35C.

Page 3 2. APPLICATIONS. Dehumidifiers in the CR-LK range is used for dehumidification of ambient air at normal atmospheric pressure. This can be an installation for moisture control in an unheated store room, in a water work building, production room for hygroscopic materials... - with the dehumidifier in a separate installation. Normally the dehumidifier will be placed on the floor, on a table or in a wall bracket (option). It should always be placed horizontal, resting on the four pcs. rubber supports. The air to the dehumidifier should be free from solvents or other explosive components, exhaust gases from Diesel engines and should be free from pollution from solid particles. For air to the dehumidifier the following limit values must be respected : - max. humidity 100 %RH - max. temperature 35C *) - max./min. pressure ambient +/- 300Pa The CR-LK range is for indoor, stationary installations. Should not be placed in rooms with possibility for free water on the cabinet. *) at inlet air temperatures higher than 20C or at %rh lower than 30%, a reduction of the capacity must be considered.

El 111456 : PTC heater, HRKKO3 6/24, 220-240V X1 112001 : Plug for hygrostat, female, CA3GD (112002): Plug for hygrostat, male, option, CA3LSO9ZS 112000 : Protection cover, CAOOSD4 THE INSTALLED ELECTRIC HEATER : The PTC type electric heater is only functioning when air flows through. This is the reason why no thermostats or thermostatic switch is installed, as the function of these components will be regulation of the energy for the electric heater. WARNING : DO NOT TOUCH THE ELECTRIC HEATER WHEN SWITCHED ON, AS IT IS AN UNINSULATED LIVE WIRE. 6.4 REGULATION BY HYGROSTAT. The dehumidifier is prepared for external regulation by a hygrostat. For connection, remove the cabinet top cover. Connect to the terminals 6 & 7 after removing the shunt (the terminals are internal connected a small terminal in the top of the cabinet, inside). The hygrostat should be approved for 230V/3A
Page 12 6.5 ELECTRIC CONNECTION. The dehumidifier CR110LK is connected 230V, 1N+PE. The dehumidifier is equipped with a 2m cable for the power supply. Power consumption is 1,15 KW - fused by 10A. (see below) SUBJECT : POWER CONSUMPTION & AIRFLOWS. In the electric heater the power consumption is decided by the reg.air flow - which is adjusted by the manufacturer. 7. INSTALLATION. The dehumidifier should be installed indoors, placed on the Enclosed wall bracket. CONNECTION OF DUCTS : 7.1 The process and the cooling air is normally taken from the room, through the air inlet filter. We cannot recommend to connect ducts at the air inlet and for the cooling air outlet. The dry air outlet can be connected some ducting, with regard of the available external pressure. 7.2 The drain to be connected a hose of 12 mm diameter. The hose to be installed draining away from dehumidifier to waste. In general ducts of the same size as placed on the dehumidifier should be used.
Page 13 8. START-UP PROCEDURE. 8.1 ELECTRIC. Before starting-up the dehumidifier, check that all electric connections are made correctly. - Power supply, 230V, 10A external fuse? - PE connection made and in right dimension? - Hygrostat connected (plug) If this is OK, just connect the plug of the supply cable. Switching on: Toggle switch Sl: Red, dehumidifier on/off Toggle switch S2: Black, dehumidifier auto/man (hygrostat) If the dehumidifier don't start (S2 in Pos. Auto): If the humidity (%-RH or dew point) in the air is below the value set on the humidity controller, the dehumidifier don't start (humidity OK). To check: Adjust the controller to lowest possible value, And the dehumidifier will normally start. 8.2 AIR FLOWS. No adjustment of the air flows is necessary. The dry air flow is free blowing 115 m3/h - and should not be reduced (if so, the capacity will decrease). With the electrical settings and air flows adjusted, the dehumidifier will then operate automatically by means of the internal control- and safety functions - controlled by an external hygrostat.
Page 14 9. MAINTENANCE. Dehumidifier CR011,K only needs a minimum of maintenance. All components are service free, which means no lubrication or adjustment. Only three things should be checked under normal operation: - air filter should be replaced often (3-4 times a year). - the rotation of the rotor should be checked once a month. If the rotor rotates during operation, and the fans are operating (= air flow), you are almost sure that the dehumidifier is operating correctly. We nevertheless recommend some periodic verification of the entire dehumidifier, to see if all internal functions are ok and checking of gaskets and moving parts for wear and tear. This will ensure that the capacity is on its maximum, and thus won't waste any energy. 10. TROUBLE SHOOTING. 10.1 If the dehumidifier does not start when electric connected, control the external fuse. 10.2 If the dehumidifier is not operating it is probably the external hygrostat which has broken. This is a normal situation when the desired humidity is obtained. To check : See 9.1, Switching on, above. 10.3 If the desired humidity is not obtained, the problem can be the dehumidifier - or the other parts in the total installation ( room tightness, hygrostat...). To verify this, check: - rotation of rotor? - the dry air should be app. 10C warmer than the inlet main air. If it is cold it could indicate that the rotor is not turning caused by broken drive belt or, the motor has stopped. - by hand feel the temperature of the cooling outlet air and feel the airflow. The temperature is depending on the inlet conditions, but should be 5-6C higher than the inlet process air. If it is cold, the electric heater might be defective.
Page 15 11. SERVICE/REPAIR, 11.1 SAFETY INSTRUCTION. Before opening the dehumidifier, make sure that the electric power is switched off on the main switch (plug disconnected). The dehumidifier CRO1LK is manufactured in the intention of easy cleaning and maintenance, which is important when it is used on building sites. To dismantle the dehumidifier, do like this: 11.2 Access to internal components. Place the dehumidifier on a table. Remove the rear cover, (U-shaped): - Remove the 2 black screws - Remove the 6 screws in the bottom The 2 U-sides of the cover to be twisted in opposite direction for releasing the cover. 11.3 Process air fan, heater, rotor. The plate on which the fan is fixed to be released and pulled out of the cabinet. Now fan, heater and rotor is accessible for replacing. Gearbox for rotor is accessible too (not so easy, but Possible). 11.4 Reg.air fan. Best way is to pull out the total internal assembly. This is fixed with 4 rivets in the bottem. Remove the rivets and twist the assembly. Disconnecting the cables. Removing the cover above the fan.
Page 16 12. SOUND LEVEL. The sound level is measured according to EN292-2: The dehumidifier is during the measuring of the sound level placed with the top plate 1 m above the floor. Ducts for reg. air is installed and let out of the room, and 2 m dry air duct al00 is installed too. The sound level is then measured 1 m outside the cabinet, and 0,6 m above the floor, and a sound level of 60 db(a) is measured. MANUFACTURED BY : COTES A/S Industrivej 31A DK-4230 SkIskor.
