3�2 REFRIGERANT TYPE AND INSTALLED

LOCATION

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

Notes *Assumed worst case for access category: a - general access and location class: I - mechanical equipment in
occupied space; both as defined in line with EN378-1 2016 section 5.1 table 4 and section 5.3
*Minimum Area is calculated in line with section C.2 on EN378-1 2016 (calculation C.2)
INTERPRETATION
Please refer to the installation situations below for how
to apply the minimum area stated above.
Pool outside and heat pump outside:
Automatically meets the minimum area requirement
because outside space is unlimited.
Pool outside and heat pump inside a plant room:
Automatically meets the minimum area requirement
because the room must open to the outside for heat
pump airflow and the outside space is unlimited.

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