Regulations / Safety Notices This installation and operating manual must be read prior to starting up the unit ! ¾ ¾ ¾ ¾ # # # # The heat pump for cooling of domestic water (short: HPCDW) is designed exclusively for the cooling (in part also for the heating) of domestic or potable water within the specified operating temperature limits! The cooling (or heating) of liquids other than drinking water is not permissible. -
Page 4: Description
Description The HPCDW is a domestic water cooling unit ready for connection and essentially consists of a domestic water tank, the components of the refrigeration, air and water circuits as well as all control, regulating and monitoring devices required for automatic operation. In accordance with the heat pump's principle of operation, unwanted heat is extracted from the domestic water and then transferred to the discharged outlet air. -
Page 5: Safety And Control Devices
Safety and Control Devices The HPCDW is equipped with the following safety features: 2.3.1 High-pressure pressostat (HD) The high-pressure pressostat protects the heat pump from excessive operating pressures in the refrigeration cycle. In the case of a malfunction, the pressostat switches off the heat pump; the heat pump is restarted automatically as soon as the pressure in the refrigeration cycle has dropped to an acceptable level. -
Page 6: Storage / Transport
Storage and Transport General Requirements As a rule, the CWP is to be stored or transported in its shipping box in upright position and without water charge . For a transport over short distances, and provided due care is exercised, an inclination angle of up to 45° is permitted. -
Page 7: Installation
If the ceiling is lower and no airducts are used, an air ducting elbow (90° NW 160) must be used on the outlet air side (to ensure effective operation). When an air ducting elbow is used, care must be taken that it is slipped onto the flange collar of the discharge side in such a way that the discharge opening of the air ducting elbow is as far away from the intake opening of the unit as possible. -
Page 8: Electrical Connection
Electrical Connection The HPCDW is pre-wired, ready for connection, the power is supplied via the mains cable connected to a socket with earthing contact (GB: "Home Office socket") (~230 V, 50 or 60 Hz). This socket must be accessible also after the installation has been completed. -

Page 11: Water Circuit
Water Circuit The inspection of the water circuit is limited to any filters that may have been field-installed, and the performance of leak tests. Dirty water filters have to be cleaned and replaced, if necessary. Air Circuit The maintenance activities are limited to cleaning the fin-type heat exchanger (only) as required. Caution! Hazard of injury from sharp-edged fins. -
