3 Commissioning
3.1 Preparations
If the storage tank is not preheated before commissioning, the
compressor will become damaged. The manufacturer shall not be liable
for any such damage.
Before commissioning, preheat the storage tank.
1. Ensure that the storage tank has been filled with water.
2. Prevent the compressor from starting by pressing down the button on the motor
protection circuit breaker.
3. Turn on the ground source heat pump.
The unit's electric immersion heater will start to heat up the water in the tank.
The error message “Compressor 1 circuit 1 some motor protection gone off.
Check motor protection F1, F2 or F3” will appear on the display. Later, the
system will give out another regulator alarm: “Resistor functioned in full power
system”. No user action is required for these error messages.
Once the storage tank has been preheated for 6 hours, you can start the
commissioning process.
3.2 First start checklist
Before the first start, check the following:
1. The heating system has been appropriately connected, filled, and bled of air.
2. The brine circuit has been appropriately connected, filled, and bled of air.
3. All electrical connections have been made appropriately.
4. The outdoor sensor (and, if present, the optional indoor temperature sensor) has
been installed.
5. The electric immersion heater has been preheating the water in the storage tank
with compressor operation blocked for at least 6 hours.
3.3 Typical problems during commissioning

Problem Cause Solution
Wrong fuse type.
Check that the fuse is an
automatic C or D fuse or a
ceramic fuse (slow-blow or
marked with a snail).
Fuses always blow when the
compressor starts.
Temporary site distribution board
connections are causing an
overload in the fuses.
Reduce the load.
Brine pump does not start
The control system is not getting
power.
Check the control fuse.
