Handling
The heat pump contains highly flammable refrigerant.
Special care should be exercised during handling, in-
stallation, service, cleaning and scrapping to avoid
damage to the refrigerant system and in doing so re-
duce the risk of leakage.
NOTE
Work on the refrigerant system must be done
by authorised personnel in accordance with
the relevant legislation on refrigerants, supple-
mented by additional requirements for flam-
mable gas, for example, product knowledge
as well as service instruction on gas systems
with flammable gases.
Safety precautions
Wiring
Check that cabling will not be subject to wear, corro-
sion, excessive pressure, vibration, sharp edges or any
other adverse environmental effects. The check shall
also take into account the effects of aging or continual
vibration from sources such as compressors or fans.
Repairing sealed components
When repairing sealed components, all electrical supply
must be disconnected from the equipment that is being
repaired before any sealed covers or similar are re-
moved. If it is absolutely necessary to have an electricity
supply to the equipment during the service, continu-
ously activated leak tracing must be performed at the
most critical points in order to warn of any dangerous
situations.
Pay particular attention to the following so that the
sheath is not changed in a way that affects the protec-
tion level when working with electrical components.
This means damage to cables, unnecessary amounts
of connections, terminals that do not follow the original
specifications, damaged gaskets, incorrect grommets
etc.
Ensure that the apparatus is secured properly.
Check that seals or sealing materials have not deterior-
ated to a degree that they can no longer prevent
combustible gases from entering. Replacement parts
must meet the manufacturer's specifications.
NOTE! Use of silicone seals can hamper the efficiency
of certain types of leak tracing equipment. Components
with built in safety do not need to be isolated before
starting work.
When working in the refrigerant circuit
Pipe installation should be kept to a minimum.
Connections in the refrigerant circuit must be carried
out as follows:
Soldered, welded or mechanical connections must
■
be made before the valves are opened to allow the
refrigerant to flow between the cooling system parts.
The system must be equipped with a vacuum valve
to relieve connecting pipes and/or any unfilled parts
of the cooling system.
