7.1. Information regarding the start-up

Before starting up the TERRA heat pump ensure wa-
ter tightness on the heating side, rinse the heat pump
thoroughly, fi ll and ventilate the heat pump carefully.
Start-up requirements
- The heating and a possibly existing storage tank
have to be fi lled and ventilated.
- In the heat pump return, a fi lter ball valve is installed
in front of the condenser. After the system has been
fl ushed for at least 30 minutes, the fi lter must be
cleaned (see chapter Hydraulic connection, section
Cleaning fi lter ball valve).
- At the start-up the complete heating buff er has to be
heated up to min. 20 °C. This can be performed e.g.
with the electric heating rod.
- The electrical installation must be completed and
fused properly.
- The heat pump may only be switched on if it is
properly fi lled on the coolant side as well as on the
heating side and if the electrical connections are in
place.
- At the start-up the maximum temperature limit has
to be set. The switch-off point at 62 °C must be
checked and, if applicable, the shut-down tempera-
ture then adapted.
- The heat pump is furnished with a delay time of 10
minutes, so that the compressor only starts after
this start-up delay.
- If the heat pump is to be drained on the heating
side in a frost-proof mode, the connection hose has
to be loosened at the heat pump return (plate heat
exchanger).
7.2. Switching the heat pump on for the very fi rst time
After pressing the main switch on the heat pump, the
start-up assistant is started after selecting the desired
