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

Installation site
6.2.1.
General information
The chiller is approved for indoor installation (installation site classification I) - as well as for outdoor
installation (installation site classification III) for the access area categories (b) "monitored access area" and
(c) "access area to which only authorised personnel have access" (note option packages). DIN EN 378-1. 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. The
installation of exhaust air ducts is not allowed.
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.
ATTENTION! Do not install in rooms with naked flames or smoke.
