Use and Care Manual

A) When operating the air dryer the operator must apply safe working methods and observe all local safety
instructions and relevant regulations.
B) Prior to installation, the dryer and the compressed air system are to be depressurized and disconnected
from the electrical main supply.
C) The user is responsible for safe operating conditions. Parts and accessories must be replaced if inspection
shows that safe operation cannot be assured.
D) Installation, operation, maintenance and repair are only to be authorized, trained and skilled engineers.
E) The minimum and maximum values stated must be observed, as well as all of the safety precautions described
in this manual.
F) If any statement in this manual does not comply with the local legislation, the strongest standard is to be applied.
1.1. Transportation
A) Use care and caution when transporting the dryer. Avoid dropping and other physical abuse.
B) A forklift can be used to transport the dryers provided the forks are long enough to support its full width or
length and caution is used throughout the move.
1.2. Positioning
A) The dryer must be installed horizontally. A minimum of 20” clearance around the dryer is necessary to
allow a good ventilation and easy access for servicing.
B) The ambient temperature in the room should not exceed 122°F and should not be below 39°F, taking the heat
radiated by the dryer into account.
C) (40 watt for each liter/sec under ISO 7183-A condition or 18 watts for each SCFM under ISO 7183-B condition).
1.3. Installation
A) In addition to the general mechanical construction procedures and local regulations, the following instructions
need to be emphasized:
1) Only authorized, trained and skilled engineers should install the compressed air dryer.
2) Safety devices, protecting covers or insulation in the dryers never to be dismantled or modified.
Each pressure vessel or accessory installed outside the dryer with air above atmospheric pressure must be fitted
with the required pressure relief safety valves.
1.4. Before Operating
A) Review all safety precautions.
B) The piping must have the correct diameter and be adapted to the operating pressure (see technical specification).
C) Never operate the dryer at pressure above the maximum specified on the dryer label (check the technical specs too).
1.5. Maintenance by an Engineer
A) Maintenance and repairs should only be performed when the air dryer is shut down and depressurized and when
the main power switch is turned off.
B) Use only the appropriate tools for maintenance and repair.
C) Before dismantling a part under pressure, disconnect the pressure sources and depressurize the system.
D) Proceed carefully during maintenance and repair. Prevent dirt from entering by covering parts and orifices with
a clean cloth, paper or tape. A receiver should never be welded or modified in any way.
E) Never leave tools, loose parts or cleaning rags in or on the air dryer.
F) Before returning the dryer into service, check the setting of the control and safety devices as well as the pressure
and the temperature of the compressed air circuit.
1.6. Maintenance by the user
A) Keep the dryer clean.
B) Regularly check the correct operation of the condensate drain trap.
C) Every six months, check and clean the drain strainer by undoing the access screw and rinsing the filter with tap
water to remove the trapped dirt from the inside.
