Toxicity
Under normal operating conditions, the heat pump refrigerant is not toxic. However, despite its low toxicity,
injury can occur during abnormal operation.
•
In its gaseous state, the refrigerant is heavier than air, so it tends to accumulate in low areas. If the
equipment is installed in a place where refrigerant vapour may accumulate at ground level, it must
be well ventilated.
•
Directly exposing the refrigerant to a flame produces toxic gas. However, this gas is detectable by
smell at concentrations well below the permitted limit. If you notice an unusual smell, evacuate
and ventilate the area to ensure complete removal of the gas.
•
In case of accidental refrigerant leakage, ventilate the room immediately.
•
Everyone who has come into contact with refrigerant vapour must be evacuated immediately and
breathe fresh air.
Inflammability
Normally, there is no risk of explosion or combustion of the refrigerant in the refrigerant circuit.
Repairs and scrapping
To service the refrigerant circuit, the refrigerant contained therein should not be discharged into the
atmosphere, but should be recovered and destroyed in special treatment plants designed for that purpose.
Because R410A is a refrigerant mixture, in the event of a leak, it is necessary to add additional refrigerant
liquid. Adding the refrigerant in its gaseous state alters its composition and can cause the heat pump to
malfunction.
Before scrapping the heat pump, its refrigerant must be recovered for destruction in a treatment plant,
according to current regulations.
2.2
Hydraulic circuits
However, any action on the heating/cooling, brine or DHW circuits should be performed only by authorized
personnel according to applicable local regulations and the instructions provided in this manual.
DANGER!
Do not touch the pipes, or other components of the heating, brine or DHW circuits during or
immediately after operation of the heat pump, as they may be very hot or very cold. If you touch
them you might suffer burns from heat or cold. If you must touch these components, allow
sufficient time for the temperature to stabilize and wear protective gloves to avoid injury.
