WARNING
Provide adequate measures to prevent that the unit can be used as a shelter by small
animals. Small animals that make contact with electrical parts can cause
malfunctions, smoke or fire.
WARNING
Some sections of the refrigerant circuit may be isolated from other sections caused
by components with specific functions (e.g. valves). The refrigerant circuit therefore
features additional service ports for vacuuming, pressure relief or pressurizing the
circuit.
In case it is required to perform
brazing
on the unit, ensure that there is no pressure
remaining inside the unit. Internal pressures need to be released with ALL the service
ports indicated on the figures below opened. The location is depending on model
type.
