Please observe these instructions, otherwise the manufacturers liability for subsequent damage will be cancelled. All rights required for further technical development and modification, are reserved. IMPORTANT! Proper use of the chiller This chiller is designed for the cooling of water only. deionised water) please contact the manufacturer. Limits indicated in the technical data must be adhered to strictly, otherwise the manufacturers liability for subsequent damage will be cancelled. [. . . ] To avoid thickening of the tank water, we recommend to replace the system content every 1 to 3 months. an increasing evaporation of the tank water means an increasing chloride content ( please refer to chapter 6). For chillers running at temperatures lower than freezing point, a water/glycol mixture at the appropriate ratio should be filled. 30% Glycol up to ­10°C, at lower temperatures please refer to the manufacturer. Prior to start up it is always necessary to prime the pump with the medium to be transported. Prior to start up the pump must be bled in order to remove air from the pump. Bleeding of the pump Remove bleeding screw P (option) Reinstall bleeding screw and tighten as soon as medium exits from filler fitting. Important: Ventilation of the pump before start the process, following steps are to relize for ventilate the pump: check the waterlevel in the tank and refill it, if necessary open the outlet of the pump, or connect only the outlet of the pump, let the inlet free flow out If there is still some air in the system, you have to repeat the steps as described before. After open the outlet start the pump for a short time. Attention before start the operation of the pump, the function of this pump must be absolutly check. In case that the pump after a longer standstill and ventilation stopp , you have to introduce a screwdriver through the airgrille into the shaft and turn it clockwise (1-2 turns min. ), until a easiness is produced. Operating Instructions 7 3 INSTALLATION AND INITIAL OPERATION Start­up of chiller After successful completion of all instructions given in this chapter, the refrigerating plant is switched on by means of the main switch or master switch (if installed). The OPERATION light will light up during normal operation. Master switch position: O = Off 1 = Operation In case of irregularities occurring during operation or extraordinary noise, the chiller has to be switched off by means of the control switch (please contact the manufacturer). Confirm the correct power supply connection. The direction of rotation of the fan motor must turn in the same direction as the arrow. 8 Operating Instructions 4 CARE AND MAINTENANCE General In case of irregularities occurring during operation or extraordinary noise, the chiller has to be switched off by means of the main switch or if missing over the power supply. Fluid (water) Cleanliness of the water/fluid should be tested daily. In case of any problems concerning the refrigeration cycle, please contact the manufacturer Note: Please ensure to switch »0« the main switch, before any maintenance or repairment work has to be performed on the chiller. Operating Instructions 11 5 FAULT DIAGNOSIS Fault Refrigeration cycle Possible cause Repairement A. Compressor and fan motor running, but chiller has no cooling capacity Refrigerant leakage refrigerant level to low Dirty condensor Ambient temp. to high Consumer capacity to high Repairement by qualified refrigeration technician only Clean condensor Refer to technical specifications Refer to technical specifications B. Compressor and fan motor is not running Temperature controller setting incorrect Temperatur controller defect Re-adjustment of temp. controller Replacement by qualified technician only Switch off the chiller and restart after 3 hours only. If compressor does not start, replacement by qualified refrigeration technician only. If compressor starts, refer to D. Fan Motor defect C. Compressor does not run, but fan motor is running Compressor Bimetal/Clixon switches compressor of due to overheating Switch off the chiller and restart chiller after 3 hours only. If compressor does not start, replacement by qualified refrigeration technician only. Refrigerant leakage refrigerant level to low 2.
