6. Installation
6.1. Overview
Several tasks are necessary to install the chiller. The following work schedule shows the order in
which they are carried out:
▪ Prepare the installation site
▪ Install the machine
▪ Flush the cold water circuit
▪ Hydraulic installation
▪ Fill the whole system
▪ Vent the whole system
▪ Electrical installation
6.2. Installation site
6.2.1. General information
The chiller is suitable for both indoor and outdoor installation (note options packages). The
electrical degree of protection corresponds to IP54. If installed indoors, ensure sufficient air
exchange. An enclosed room will steadily heat up and the machine can switch off due to a lack of
cooling. The exhaust heat from the machine can be approximately calculated as 1.3 x net
refrigeration capacity. The air flow rate required for your machine is given in Table 3 Technical
data. When choosing the installation site, ensure that waste heat from other processes cannot be
guided directly onto the air intake side of the chiller.
6.2.2. Minimum room volume
The refrigerant R410A contained in the system is classified in safety group A1 in accordance with
EN 378-1 Table E.2. I.e. the refrigerant is not flammable and has low toxicity. If the chiller is
installed in enclosed rooms without additional safety measures a minimum room volume is
required. This is due to the maximum concentration occurring in an area occupied by persons in
the event of release and depends on the refrigerant quantity in the chiller. Please refer to the
following table for the value to be complied with for your machine.
