Warning! Risk of personal injury! Refrigerant exposed to a naked flame creates a poisonous irritating gas.
This gas can be detected by its odour even at concentrations below its permitted levels. Evacuate the area
until it has been sufficiently ventilated.
Warning! Risk of personal injury! Anyone with symptoms of poisoning from the vapour must immediately
move or be moved into the fresh air.
Work on the refrigerant circuit
When repairing the refrigerant circuit, the refrigerant must not be released from the heat pump – it must be destroyed
at a special plant. Draining and refilling must only be carried out using new refrigerant (for the amount of refrigerant
see manufacturer's plate) through the service valves. Filling with refrigerant other than R410A voids all guar-
antees from Thermia Värme AB, unless this new refrigerant has been approved in writing as an alternative refrigerant
together with other corrective action.
Scrapping
When the heat pump is to be scrapped the refrigerant must be extracted for disposal. The local regulations for
treatment of refrigerant must be followed. See the relevant Swedish Environmental Protection Agency refrigerant
statutes.

Noise and vibrations
2.2.1
Flexible hoses
All pipes should be routed in such a way that vibrations cannot be transmitted from the heat pump through the
piping and out into the building. This also applies to the expansion pipe. We recommend that flexible hoses are used
for all pipe connections to avoid the transmission of vibrations. Flexible hoses are available to purchase as accessories.
The figures below show how appropriate and inappropriate installations look using this type of hose.
