FINO 91463, User Information

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

.

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.
