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 13, point 17
•
Pressure in the ground heat exchanger system, see Figure 13, point 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 13, point 28
Check list for brine/water pump system at start-up and commissioning must be reviewed before
starting.
The heat pump can then be switched on at the safety switch.
The heat pump is shut off at the safety switch.
