The installation location of the chiller has been
reasonably planned by referring to 3.1.2
Physical Dimension, 3.1.3 Installation
Environment and 3.1.4 Installation Layout.

The packaging of the chiller has been
disassembled, and the installation tools and
accessories listed in the packing list are ready.

The coolant pipelines (diameter: DN28, pipeline
pressure ≥ 3.5bar) have been prepared.
Precautions

The pull ring on the front of the chiller is only used for
pulling the maintenance panel. It is forbidden to use it
as a force support to move the chiller upwards.

To avoid condensation, use insulated and thermal
insulated pipes for connection.

The coolant inlet and outlet of the chiller adopts quick
connectors, and the specifications of the connecting
pipes must conform to the specifications of the coolant
inlet and outlet ports.

It is suggested to install stop valves between the inlet
and outlet connecting pipes of the chiller and the
equipment to be cooled, so as to maintain the chiller or
the equipment to be cooled later.
