    Regulations / Safety Notices This installation and operating manual must be read before the unit is started up! ¾ ¾ ¾ ¾ # # # # The heat pump water heater (HPWH) is designed exclusively for the heating of domestic or potable water within the specified operating temperature limits! The heating of liquids other than drinking water is not permissible.
  • Page 4: Description

    Description The HPWH is a heating appliance 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. The desired fan speed (3 settings) can be selected via a wire-bound remote control.
  • Page 5: Water Circuit

    Water Circuit The water circuits of the HPWH are dependent on the specific type (with or without internal heat exchanger). They have to be field-installed. The water connections (Fig. 1) are located at the rear of the unit. Ø Ø (Cable entries for (Leitungseinführungen 1660...
  • Page 6: Safety And Control Devices

    Safety and Control Devices The HPWH is equipped with the following safety features: 2.3.1 High-pressure pressostat (HP) 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 7: Storage / Transport

    Storage and Transport General Requirements As a rule, the HPWH 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 8: Installation

    The notices below apply to the connection of the HPWH to exhaust air duct systems: Standardised exhaust air systems: Standardised exhaust air distribution systems with decentralised outside air valves are offered for use with the HPWH. The connection of these systems to the unit is accomplished via a flexible, sound and heat insulated airduct (DN 160).
  • Page 9: Mounting

    Mounting Connection of Water Piping The nominal pipe widths of the field-installed sanitary installations must be determined on the basis of the available water pressure and the expected pressure drops within the piping system. The water-side installation has to be executed in compliance with DIN 1988 (see appendix – in the case of excessive water pipe pressure, a pressure relief valve is to be provided, among other things !) The water pipes may be of the rigid or flexible type.

  • Page 12 Ventilation mode If the 'heat pump' switch on the heat pump is in position “ “ (Off), the HPWH can be operated in the ventilation mode, provided the slide switch '1' is in position " I ". In this case, three ventilation settings can be selected without the water heating function of the heat pump being activated.
  • Page 13: Maintenance / Service

    Maintenance / Service CAUTION! Prior to opening the HPWH, the unit must be disconnected from the power supply; be careful of fan that may still be rotating! General The heat pump water heater is nearly maintenance-free. A few days following the commissioning procedure, a visual check for possible leaks in the water system or clogging of the condensate drain is to be performed once.
  • Page 14: Sacrificial Anode

    Sacrificial Anode The sacrificial anode installed in the hot water tank for corrosion protection purposes, must be checked electrically on a regular basis, at least every two years after commissioning, and be replaced, if necessary. The electrical check is to be conducted by means of a suitable ammeter without draining the water in the tank. Procedure: Withdraw PE conductor from tab of sacrificial anode.
