ADDRESSES OF ASSISTANCE CENTERS
In the event of breakdown or malfunction of the machine, switch it off and do not
tamper with it.
If repairs are needed, contact a technical assistance center approved by the
manufacturer and insist on the use of original spare parts.
Failure to comply with the above may endanger the safety of the machine.
Keep this manual with care for future consultation; the use and maintenance manual
is an integral part of the machine.
Read this manual carefully before carrying out any operations on the compressor
unit. The installation of the compressor unit and all operations involving it must be
performed in conformity with the regulations in force concerning electric plants and
personal safety.

1 GENERAL SAFETY STANDARD
BEFORE REMOVING THE PROTECTION DEVICES FOR ANY MAINTENANCE WORK ON
THE MACHINE, DISCONNECT THE ELECTRICAL POWER SUPPLY. MAKE SURE THAT
THERE IS NO INTERNAL RESIDUAL PRESSURE.
ALL WORK ON THIS MACHINE MUST BE CARRIED OUT BY AUTHORISED &
PROFESSIONALLY SKILLED PERSONNEL.
Note: Any tampering with the machine or alterations not approved beforehand by the
manufacturer relieve the latter of responsibility for any damage resulting from the above
actions.

Introduction
The dryer is a chilling machine with direct expansion and dry evaporator. The air to be dried
is sent to the heat exchanger in which the water vapor present is condensed: the
condensate gathers in the separator and is discharged outside through a steam trap.

Heat exchanger

Dew point indicator
Description
Compressed air enters heat exchanger (10) and is cooled by the outgoing, cold, dried air.
Water in the incoming air starts to condense. The air then flows through heat
exchanger/evaporator (10 & 4) where the refrigerant evaporates causing the air to be
cooled further to close to the evaporating temperature of the refrigerant. More water in the
air condenses. The cold air then flows through separator (5) where all the condensate is
separated from the air. The condensate is automatically drained in the condensate drain (6).
The cold, dried air flows through heat exchanger (10) where it is warmed up by the incoming
air to approx. 10˚C (18˚F) below the incoming air temperature. Condensation in the air net
cannot occur unless the air is cooled to below the pressure dew point indicated by the digital
dew point indicator (11).

Hot gas by-pass valve
Description
Compressor (1) delivers hot, high-pressure refrigerant gas which flows through condenser
(2) where most of the refrigerant condenses. The liquid flows through liquid refrigerant
dryer/filter (8) to capillary tube (7). The refrigerant leaves the capillary tube at evaporating
pressure. The refrigerant enters evaporator (4) where it withdraws heat from the
compressed air by further evaporation at constant pressure. The heated refrigerant leaves
the evaporator and flows through the liquid separator (9) back to the compressor (1).

Hot gas by-pass valve
Description
The condenser pressure must be kept as constant as possible to obtain stable operation. Fan
control switch therefore stops and starts the cooling fan (3). If, under partial or no load, the
evaporator pressure drops below a certain level, the hot gas by-pass valve (9) opens and hot,
high-pressure gas is fed to the evaporator circuit to prevent the evaporator pressure from
dropping any further.
