User manual

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.

9.4 Work on the refrigerant circuit

Caution When repairing the refrigerant circuit, the refrigerant must not be released from the heat pump, it must trea-

ted in the appropriate way.

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 from Danfoss are void if, when filling with refrigerant other than Danfoss A/S specified refriger-

ant, if there has not been written notification that the new refrigerant is an approved replacement refrigerant

together with other remedies.

9.5 Scrapping

Caution When the heat pump is to be scrapped the refrigerant must be extracted for disposal. Local rules and regula-

tions related to the disposal of refrigerant must be followed.

9.2 Electrical connection

Warning Hazardous electrical voltage! The terminal blocks are live and can be highly dangerous due to the risk of elec-

tric shock. All power supplies must be isolated before electrical installation is started. The heat pump is con-

nected internally at the factory, for this reason electrical installation consists mainly of the connection of the

power supply.

Caution Electrical installation may only be carried out by an authorized electrician and must follow applicable local

and national regulations.

Caution The electrical installation must be carried out using permanently routed cables. It must be possible to isolate

the power supply using an all-pole circuit breaker with a minimum contact gap of 3 mm. (The maximum load

for externally connected units is 2A).
