Filling and bleeding air
A standard chiller provides vent valves at the evaporator and at the electric cabinet cooler. For accessing the
vent valves of the electric cabinet cooler, remove the left side panel of the electric cabinet. For purging the
cabinet cooler it is sufficient to open one of the two valves.
If the chiller is equipped with free cooling, there are also vent
valves on top of the free cooling coils. The following drawing
illustrates the diagonal arrangement system of the valves.
• Remove the rubber plugs and also connect hoses here, if
necessary to catch the mixture.
• Begin filling the water circuit. As soon as liquid comes out of
a vent valve for several seconds, this can be closed.

• Open the vent valves. See the exact location of the vent
valves in the refrigeration scheme. If the planned filling
of water contains glycol, connect fill hoses to the vent
valves, to catch the discharging mixture and dispose of it
separately.
• Check equally whether the stop valves in the supply line of
the cabinet cooler are open.
