Refrigerant - Danfoss DHP-A Installation Instructions Manual

Caution! The hot water tank must be equipped with an approved safety valve.
Caution! Heating systems with closed expansion tanks must also be supplied with approved pressure
gauges and safety valves.
Caution! Cold and hot water pipes and overflow pipes from safety valves must be made of heat resistant
and corrosion-resistant material, e.g. copper. The safety valve overflow pipes must have an open
connection to the drain and visibly flow into this in a frost-free environment.
Caution! The connecting pipe between the expansion tank and the safety valve must slope continuously
upwards. A continuous upwards slope means that the pipe must not slope downwards from the
horizontal at any point.
Note! If there is any risk of groundwater infiltration at wall lead-ins for brine pipes, watertight grommets
must be used.
Note! In addition to applicable local rules and regulations the installation should be carried out in a
manner that prevents vibrations from the heat pump being transmitted into the house causing noise.
2.1

Refrigerant

Caution! Work on the refrigerant circuit must only be carried out by a certified engineer!
Although the heat pump cooling system (refrigerant circuit) is filled with a chlorine-free and environmentally-
approved refrigerant that will not affect the ozone layer, work on this system may only be carried out by author-
ized persons.
2.1.1 Fire risk
The refrigerant is not combustible or explosive in normal conditions.
2.1.2 Toxicity
In normal use and normal conditions the refrigerant has low toxicity. However, although the toxicity of the refrig-
erant is low, it can cause injury (or be highly dangerous) in abnormal circumstances or where deliberately abused.
Warning! Risk of personal injury! Spaces in which heavy vapour can collect below the level of the air must
be well ventilated.
Refrigerant vapour is heavier than air and, in enclosed spaces below the level of a door for example, and in the
event of leakage, concentrations can arise with a resultant risk of suffocation due to a lack of oxygen.
