7. Start-up
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.
- At the start-up the complete heating buffer 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).
