1. Description of the Heat Pump
Heat pump GELBI D4.2 is a device designed for preparation domestic hot water. It uses the rotary
screw compressor optimised for high condensation temperatures, i.e. enabling heating to high
temperature. The air flow is forced via the finned coil by modern, powerful and energy efficient fan.
Water is heated in the SWEP plate exchanger made of stainless steel. Hot water circulation is forced
by WILO circulating pump adapted also to work directly with tap water. The correct operation of the
heat pump is supervised by a controller with an algorithm optimised for the design of the GELBI D4.2
heat pump. The housing is made of ABS plastic. All the above mentioned characteristics and
components comprise the high quality and efficiency of the heat pump.
2. Construction of the Heat Pump
Power supply cord and tank and buffer sensor are located at the back of the device.
3. Installing of the Heat Pump
3.1 Precautions during installation of the device
Installation of the heat pump should be performed by a person with appropriate qualifications in the
field of heating and cooling devices. The country-specific health and safety regulations must be
observed during installation.
3.2 Installation recommendations
GELBI D4.2 heat pump should be installed in a room where the temperature does not drop below +
5°C. If the temperature may fall below +5°C, the water circuit between the heat pump and the
storage tank must be emptied and the system has to be blown out well, e.g. with compressed air.
During the installation process heat pump should be levelled by adjusting height of the legs. Failure
to comply with this recommendation may result in a defective work and eventually damage to the
equipment.
