1. Fields of application
The FINO refrigeration dryer removes humidity from
the compressed air by cooling it down to nearly free-
zing point. This condenses the humidity in the com-
pressed air. The formed condensate is expelled
automatically. The air is heated prior to leaving the
refrigeration dryer. This reliably protects against cor-
rosion damage and thus extends the service life of all
technical equipment and instruments.
2. Safety precautions
The air generated by the refrigeration dryer does not
have breathing air quality. To generate breathing air
quality, the compressed air needs to be cleaned in
accordance with applicable laws and standards.
Never play with compressed air. Do not direct the jet
of compressed air at the skin or third parties. Under
no circumstances use compressed air to remove dirt
from clothes. Do not walk or stand on the refrigera-
tion dryer or its components.
The refrigeration dryer contains refrigerants:
• Do not inhale refrigerant vapours under any
circumstances. Ensure that the work room is
adequately ventilated, otherwise use breathing
protection.
• Direct contact with refrigerants causes frostbite
of the skin. Always wear refrigerant-resistant
gloves to prevent localised hypothermia. If the
skin comes into contact with refrigerants, rinse
with water. If liquid refrigerant penetrates through
clothes to the skin, then under no circumstances
should the clothes be removed, instead apply
copious amounts of clear water to the clothes
until the entire refrigerant has been rinsed off,
then seek medical attention.
3. Commissioning
3.1 Prior to commissioning
Read the instructions for use carefully and keep
these readily available.
The device is to be checked on one's own responsi-
bility for operational safety prior to use. Defective
parts are to be replaced immediately. Prior to con-
necting the piping, remove all stoppers, caps or
bags of drying agents. Select air hoses and distribu-
tor pipes and connections of the correct size corres-
ponding to the operating pressure.
3.2 Location
Position the refrigeration dryer indoors on an even,
load bearing surface. Keep a minimum distance of
1.5 m between the top of the device and the room's
ceiling. Keep a minimum distance of 1.5 m between
the back of the compressor and the room's walls (1).
Choose the position of the refrigeration dryer such
that the ambient air is free of dust and the minimum
and maximum ambient temperature are maintained
(cf. Technical data » Limit values). The intake air
must not contain any inflammable particles, for
example, solvents, which could explode or ignite
inside the device. Do not block the air intake under
any circumstances. Ensure that loose-fitting clothing
cannot be sucked in.
Ensure that the pipelines can expand at heat and are
not positioned near combustible material.
No external forces may act on the air outlet valve.
The connected pipelines must be free of tension.
The electrical connections must comply with applica-
ble regulations. The refrigeration dryer must be
grounded and secured against short-circuiting with
fuses for all phases. A lockable circuit breaker (2)
must be installed in the immediate vicinity of the
device.
3.3 Installation
Provide the dryer with the voltage given on the type
plate via a power cable (1). Lay the condensate drain
hose (2) to the condensate collector via a funnel for
visual inspection of the effluent.
Attach an air inlet line and an air outlet line (5) inclu-
ding seal (6) to the marked inlet (3) and outlet pipes
(4) of the refrigeration dryer. Seal the ends of the
valves well with Teflon tape and screw a coupling (7)
to each. Connect the compressed air lines.

4. Commissioning
4.1 Safety precautions
Do not operate the machine outside the limit values.
Keep all sound-proofing covers closed during opera-
tion. Wear hearing protection if a sound-proofing
cover has to be opened for a short time, e.g. to per-
form routine inspection.
Check regularly that:
• all panels are fitted and secured safely,
• all hoses and pipes in the machine are tight,
• all securing elements are tightened firmly,
• the safety valves and other overpressure devices
are not blocked through dirt or paint,
• the air outlet valve and air network is free of wear
or damage.

4.2 Operation
pressure dew point indicator (1)
ON/OFF switch of the dryer (2)
To ensure best efficiency, do not operate the
ON/OFF switch of the dryer repeatedly over a short
period of time. Do not restart the dryer before
at least 5 minutes after switching off to allow
pressure compensation.
Start the dryer before the compressor and
switch off after the compressor to avoid forming
condensate in the compressed air network.
Starting:
1. Operate the ON/OFF switch of the dryer.
2. Open the air inlet valve.
3. Open the air outlet valve
approx. 5 minutes later.
4. The nominal dew point is reached
approx. 10 minutes later.
Stopping:
1. Close the inlet and outlet valves of the dryer.
2. Operate the ON/OFF switch of the dryer.
The dryer stops.
The following should be checked regularly:
• the pressure dew point indicator on the operating
panel. Under conditions deviating from the
nominal conditions (air inlet conditions or volume
flow), the pressure dew point will also deviate
from the nominal value.
• whether condensate flows out via the condensate
drain. The volume depends on the operating
conditions.

5. Maintenance
All maintenance work should be carried out after
cooling of the machine.
Close the inlet and outlet valves and release the
pressure in the dryer by operating the test key on the
condensate drain. Then switch off the power voltage.
Open the circuit breaker to prevent unintentional
starting.
Only perform maintenance work and repairs with
suitable tools and safety wear. Only use original
spare parts. Do not perform repairs in the refrigera-
tion dryer yourself, contact the dealer.
Observe cleanliness during all maintenance work.
Cover components and exposed openings with clean
cloths, paper or tape to keep dirt away. Under no cir-
cumstances should corrosive or inflammable sol-
vents or carbon tetrachloride be used for the
cleaning of components. Protect the motor and
electrical components against moisture, for exam-
ple, during steam cleaning.
Under no circumstances should welding or other
modifications be carried out on the pressure vessel.
If overheating of an internal component is
suspected, stop the machine. Do not open any
panels until the machine has cooled down sufficient-
ly to avoid the risk of spontaneous inflammation of
the oil vapours at the air inlet.
Under no circumstances use a light source with open
flame to inspect the interior of the device.
Ensure that no tools or other loose parts are left in or
on the machine.
Prior to releasing the refrigeration dryer for renewed
operation, ensure that the settings for operating
pressure, temperature and time are correct. Check
whether the control and cut-off devices are installed
and in perfect working condition.
6. Cleaning
Always keep the refrigeration dryer clean.
Take the same safety precaution before cleaning as
those before maintenance.
Clean the filter once a week. To this purpose, remo-
ve the filter from the automatic condensate drain.
Clean from the inside to the outside with an air jet.
Then re-install the filter.
Brush or air-blast the ribbed surface of the conden-
ser once per month. Do not clean with water or
solvents.
7. Storage
Store the device in its original packaging vibration-
free in a dust-free and dry place at a temperature
between 0 °C and 40 °C.
