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. The technical regulations for the drinking
water installation (DIN 1988) must be adhered to.
¾ ¾ ¾ ¾ # # # # The air supplied to the unit should not exceed a temperature of +45 °C. The energy-efficient operation of the
heat pump decreases as the air temperature increases.
¾ ¾ ¾ ¾ # # # # The following is not permitted:
- operation using exhaust air posing an explosion hazard or containing solvents
- use of exhaust waste air laden with grease, dust or sticking aerosols
- connection of exhauster hoods to the ventilation system
¾ ¾ ¾ ¾ # # # # The unit must not be installed:

The qualified expert must ensure that prior to the commencement of any maintenance/repair activities on
refrigerant-carrying parts, the refrigerant has been removed to such an extent as necessary for the safe
performance of this work. The refrigerant must be handled and disposed of in accordance with applicable
regulations and must not be released into the atmosphere! (Refrigerant R134a is CFC-free, non-flammable
and has no ozone-depleting properties.)
¾ ¾ ¾ ¾ # # # # When working on the HPCDW, the unit must always be disconnected from the power source.
¾ ¾ ¾ ¾ # # # # The electrical connection of the HPCDW must be performed according to and conforming with all relevant
VDE, EN and IEC standards. Beyond that, the technical connection requirements of the local utility company
have to be observed.
Caution!
Any work on the cooling/domestic water heat pump may only be performed by qualified persons! All
relevant accident prevention regulations have to be observed !
