Evaporator Piping
Drains
GVAF chillers are equipped with 2 drain connections with valves: one located on the input box and the other on the
back box of evaporator.
Figure 6 – Drain and vent position on evaporator
Figure 7 – Drain and air vent fitting location on the evaporator water side
In case of winter water drainage for freeze protection, it is mandatory to disconnect the evaporator’s heaters
to protect them from burning due to overheat. It is also mandatory to fulfill the drainage, using pressurized air,
and ensure that no water stay in the evaporator during winter season. This operation needs to be performed also
on unit just delivered by factory.
