Caution
Ensure that the temperature difference between supply and return
is 5 - 7 K, in order to reach the values in the data sheet and to
avoid disturbances. This implies larger flows, larger pipe cross
sections and corresponding pump designs.
6.2.2
Connecting the condensate drain
A condensate drain is provided to ensure that the condensate is drained
properly from the appliance.
Depending on the installation location of the heat pump, further draining of
the condensate may be necessary. The available drainage may be
insufficient, for example because it leads the water to a walkway, possibly
causing dangerous situations in the case of frost. It is also possible that
excess ice will accumulate on the roof, possibly exceeding the maximum
allowable load the roof. If this is the case, take necessary measures for
further condensation drainage.
1. Connect one end to the available drain at the bottom of the device.
2. The other end may be connected to the rainwater drain, as the water
is clean.
3. Install heat tracing to prevent the drain from freezing.

Electrical connections
6.3.1
Connecting the electrical cables
Caution
Always check that the electrical system of the building is
capable of handling the starting current of the device and has
the correct circuit breakers.
Use UV and bird pecking resistant materials for insulation that is
in the open air.
Make sure that a qualified electrical engineer installs the electrical
connection of the device.
1. Install a mains switch to the device in accordance with the applicable
standards and local regulations.
Important
Failure to connect the mains-switch and power cable in the correct
fashion is not covered by warranty. This is the responsibility of the
installer.
