Refrigerant vapour is heavier than air, and in enclosed spaces or in areas below the level of the door, for example, seepage can give rise
to high concentrations with a resultant risk of suffocation due to lack of oxygen.
Warning Risk of personal injury! Refrigerant exposed to a naked flame creates a
poisonous irritating gas. This gas can be detected by its odor even at
concentrations below its permitted levels. Evacuate the area until it
has been sufficiently ventilated.
2.2.4 Working on the refrigerant circuit
Caution When the refrigerant circuit is repaired, the refrigerant must not be re-
leased from the heat pump - it must handled appropriately.
Draining and refilling must only be carried out using new refrigerant (for the amount and type of refrigerant see manufacturer's plate)
through the service valves.
Caution All warranties will become void if a refrigerant, other than what Dan-
foss specifies, is used for refilling.
2.2.5 Scrapping
Caution When the heat pump is to be scrapped the refrigerant must be extrac-
ted for disposal. Local rules and regulations related to the disposal of
refrigerant must be followed.
2.3 Electrical connection
Warning Hazardous electrical voltage! The terminal blocks are live and can
cause death through electric shock. All power supplies must be isola-
ted before electrical installation is started. The heat pump is connec-
ted internally at the factory, for this reason electrical installation con-
sists primarily of the connection of the power supply.
Caution Electrical installation may only be carried out by an authorized electri-
cian and must follow applicable local and national regulations.
