Operation and maintenance
When setting up the system, future service and maintenance should be taken into ac-
count.
Minimum clearance in front of the system of at least 1m is recommended.
Starting the heat pump
Before starting the heat pump, check the following:
Pressure in the central heating system, see Figure 5 no. 17
Pressure in the ground loop, see Figure 5 no. 17
Check that both the central heating loop and the ground source loop have been ventilated.
The central heating circuit has an excess flow valve or other circulation, which ensures the
flow, see Figure 5, no 28
Check list for brine/water pump system at start-up and commissioning (see page 29) must be re-
viewed before starting.
The heat pump can then be switched on at the safety switch.
The heat pump is shut off at the safety switch.
