3.2 REFRIGERANT TYPE AND INSTALLED

LOCATION

This heat pump contains R32, which is an
environmentally friendly refrigerant wi a GWP
(Global Warming Potential) of 675. R32 has e safety
in use classification of A2L, being low toxicity and
lower flammability. In practical terms it is very di cult
to ignite an A2L refrigerant, but is classification
requires a risk assessment to be undertaken for e
possibility of refrigerant being released by accident into
an area connected to e heat pump, considering e
application, location of components, and e installed
refrigerant charge. This installation guidance can form
e framework for such a risk assessment for e
installation.

INTERPRETATION
Please refer to e installation situations below for how
to apply e minimum area stated above.
Pool outside and heat pump outside:
Automatically meets e minimum area requirement
because outside space is unlimited.

All flammable refrigerants will not ignite if e
concentration level in a room stays below eir lower
flammability limit (LFL). European standard EN378
defines requirements to remain far below e lower
flammable limit in case of accidental leakage. By
choosing e location as dictated by EN378-1:2016
e probability of forming a flammable atmosphere
can be eliminated. Please refer to e minimum
area for each product and e interpretation below
regarding locations of heat pump and swimming pool.
This information is provided as a guide only and does
