Refrigerant type and installed location

Risk of injury due to refrigerant leak .
This heat pump contains R32, which is an environmentally friendly refrigerant with a Global
Warming Potential [GWP] of 675 and 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 refriger-
ant, but this classification requires a risk assessment to be undertaken for the possibility of
accidental release of the refigerant into the area connected to the heat pump which must
consider 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 .
Flammable refrigerants will not ignite if the concentration level in a room stays below its
Lower Flammability Level [LFL] . European standard EN 378 defines requirements to remain
below the LFL in case of accidental leakage . By choosing the location as dictated by EN 378-
2:2016 the probability of forming a flammable atmosphere can be eliminated . Please refer to
the minimum area for each product and the interpretation that follows regarding the loca-
tions of the heat pump and swimming pool . This information is provided as a guide only and
does not supersede the regulations or health and safey requirements .
If a refrigerant leak is detected during the installation stop the process immediately and con-
tact the Dantherm Group UK Service Department . Be aware that refrigerants may not contain
an odour .
Model
Refrigerant charge
Minimum area
* Assumed worse case access category : a [general access] and location class I [mechanical
equipment in occupied space] as defined in line with EN 378-1:2016 section 5 .1 table 4
and section 5 .3 .
* Minimum area is calculated in line with EN 378-1:2016 section C .2 calculation C .2 .
Interpretation
Refer to the installation situations below for how to apply the minimum area requirements .
Pool outside and heat pump outside :
Automatically meets the minimum area requirement as outside space is unlimited .
Pool outside and heat pump inside a plant room :
Automatically meets the minimum area requirement because the plant room must be open
to the outside space for heat pump airflow and outside space is unlimited .
Pool inside and heat pump outside :
The pool hall must exceed the minimum area requirement shown in the table above .
Pool inside and heat pump inside plant room which is isolated from the pool hall :
The pool hall must exceed the minimum area requirement shown in the table above .
Pool inside and heat pump inside plant room which is ventilated to the pool hall :
The pool hall and plant room combined area must exceed the minimum area requirement
shown in the above table .
