,pansion valve

The epansion valve atomiDes incoming

refrigerant and controls the flow in accordance

with the different pressures in such a way that!

depending on the heat transport! the vapour only

becomes gaseous at the outlet of the evaporator.

,vaporator

The li5uid refrigerant evaporates in the

evaporator. The heat re5uired for this operation is

drawn from the air flowing through the

evaporator fins. This cools down the evaporator.

The refrigerant evaporates and is suc'ed in with

the absorbed heat as gas by the compressor.

Tubes and hoses of the refrigerant circuit

The miture of refrigerant oil and refrigerant -"

31=a- corrodes certain metals (e.g. copper) and

alloys and dissolves certain hose materials.

Therefore only original spare parts may be used.

E:F-ring seals

These rings seal off the connection points

between the individual components of the

refrigerant circuit.

:nly use E:F-rings that are resistant to

refrigerant -" 31=a- and related refrigerant oils.:riginal spare parts offer this guarantee.

E:F-ring seals

t :nly use once! replace.

The pressure relief valve is located on the
