Instruction book
The refrigerant enters evaporator (2), where it withdraws heat from the compressed air by further evaporation
at constant pressure. The refrigerant leaves the evaporator and is sucked in again by the compressor.
Automatic regulation
The condenser pressure must be kept as constant as possible to obtain stable operation. The fan control switch
therefore stops and starts the condenser cooling fan (11).
If, under partial or no load, the evaporator pressure drops to 7.3 bar(e) (105.8 psig), the bypass regulator (5)
opens and hot, high-pressure gas is fed to the evaporator circuit to prevent the evaporator pressure from
dropping any further.

Condensate drain system

Description
The dryers are equipped with an electronic water drain (EWD). The condensate from the condensate trap
accumulates in a collector. When the condensate reaches a certain level, it is discharged through the drain
outlet.
The condensate can also be drained by pressing the test button (1).
