Electrical Connection; Commissioning - Danfoss DHP-A Installation Instructions 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.
2.1.3 Work on the refrigerant circuit
Caution! When repairing the refrigerant circuit, the refrigerant must not be released from the heat pump,
it must treated 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 refrigerant, if there has not been written notification that the new refrigerant is an approved
replacement refrigerant together with other remedies.
2.1.4 Scrapping
Caution! When the heat pump is to be scrapped the refrigerant must be extracted for disposal. Local rules
and regulations related to the disposal of refrigerant must be followed.
2.2

Electrical connection

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).
DANGER! Hazardous electrical voltage! The terminal blocks are live and can be highly dangerous due to
the risk of electric shock. All power supplies must be isolated before electrical installation is started. The
heat pump is connected internally at the factory, for this reason electrical installation consists mainly of
the connection of the power supply.
2.3

Commissioning

Caution! The installation may only be commissioned if the heating system and brine system have been
filled and bled. Otherwise the circulation pumps can be damaged.
