General Information
7. Operation and
Maintenance
When the installer has installed your new heat pump, you should check
together that the system is in perfect operating condition. Let the installer
show you where the power switches, controls and fuses are so that you
know how the system works and how it should be maintained. Bleed the
radiators (depending on type of system) after around three days of operation
and top up with water if required.
7.1 Periodic maintenance
After three weeks’ operation and then every three months during the first
year. Then once a year:
• Check that the installation is free of leaks.
• Check that the product and system are free of air; bleed if needed –
see the section Connecting the brine system.
• Check that the brine system is still pressurised and that the fluid level in
the brine vessel is adequate/correct.
• No annual leakage control of the refrigerant is required.
7.2 Shut-down
The heat pump is shut down using the operating switch. If there is a risk of
the water freezing, drain out all the water.
