6.2. Installation site
6.2.1. General Information
The chiller is suitable for both indoor and outdoor installation (note the optional packages). An
enclosed room would heat up steadily and the machine can switch off due to a lack of cooling. The
waste heat of your machine can be calculated approximately as 1.3 x net refrigeration capacity.
The air flow rate to be supplied to your machine is given in
Table 3: Technical specifications. When
choosing the installation site, ensure that waste heat is not transferred to other processes directly
on the air intake side of the chiller.
WARNING! Do not install in rooms with naked flame or smoke emissions.
6.2.2. Minimum volume
The refrigerant in the unit is assigned to safety group A1 in accordance with EN 378-1 Table E.2.
I.e. the refrigerant is not flammable and has low toxicity. However, when installing in enclosed
rooms without additional safety measures a minimum room volume is required. This is due to the
fact that the maximum concentration occurring in a place occupied by people on release and
depends on the quantity of refrigerant required to fill the unit. Refer to the following tables for the
value to be complied with for your machine.
