Heat Pump Water Heaters
SAFETY
Intended Use
The device is designed for extracting heat from the ambient air and the utilisation of that energy for heating
domestic hot water (DHW). The DHW heat pump can be installed in the open as well as in enclosed spaces.
This appliance is intended for domestic use. It can be used safely by untrained persons. The appliance can also be
used in a non-domestic environment, e.g. in a small business, as long as it is used in the same way.
Any other use beyond that described shall be deemed inappropriate. Observation of these instructions and of
instructions for any accessories used is also part of the correct use of this appliance.
General Safety Instructions
!
Warning Injury
The appliance may be used by children aged 8 and up and persons with reduced physical, sensory or
mental capabilities or a lack of experience and know-how, provided that they are supervised or they have
been instructed on how to use the appliance safely and have understood the resulting risks. Children must
never play with the appliance. Children must never clean the appliance or perform user maintenance unless
they are supervised.
Warning Burns
The following are not permitted:
- The utilisation of greasy extract air.
- The installation of the equipment in rooms where the device is at risk from explosions as a result of dust,
gases or vapours.
Material Losses
The following are not permitted:
- The heating of liquids other than domestic hot water.
- The installation of the equipment in rooms where the temperature is below the freezing point.
- Operation of the device with an empty cylinder.
Note
Always operate the unit with a full water tank, otherwise high pressures will develop in the refrigeration
system, causing it to shut down. A manual reset will be necessary afterwards to restart the unit.
Test Symbols
See type plate on the appliance.
DEVICE DESCRIPTION
This device is a domestic hot water (DHW) heat pump.
It works as a DHW generator that operates automatically and has a capacity of approx. 300 l. The water
temperature is permanently set to 60 ¡C.
Function Description
The device extracts heat from the ambient air.
This energy is used to heat the water inside the cylinder. Where the device is installed inside a room, this is cooled
down through the heat extraction by approx. 1 to 3 ¡C. The device also extracts moisture from the ambient air that
creates condensate, which must be drained off. For this purpose, a condensate drain is integrated into the unit.
Heat Pump Operation
The table below outlines the standard operating mode, to which the limits of scope of the heat pump apply. To
heat up the cylinder capacity of approx. 300 litres of water in accordance with EN 255 part 3 to 60 ¡C, the device
requires:
