6 Maintenance
6.1
General
Maintenance operations are important for the following reasons:
To guarantee optimum performance.
To extend the life of the equipment.
To provide an installation which offers the user optimum comfort over
time.
Caution
Only qualified professionals are authorised to carry out
maintenance work on the heat pump and the heating system.
Danger of electric shock
Before any work, switch off the mains electricity to the heat pump
and the hydraulic or electrical back-up if present.
Caution
Before working on the refrigeration circuit, switch off the appliance
and wait a few minutes. Certain items of equipment such as the
compressor and the pipes can reach temperatures in excess of
100°C and high pressures, which may cause serious injuries.
Caution
Do not drain the installation, except in cases of absolute
necessity. E.g.: several months' absence with the risk of
temperatures in the building falling below freezing.

An annual inspection with tightness check is obligatory. Schedule a
service by a qualified professional at a cold time of the year to check the
following points:
1. Operation of the installation.
2. Thermal output, by measuring the difference in temperature between
heating flow and return.
3. The setting for the safety thermostats.
