페이지 인쇄PROPER USE OF THE DRYER
This dryer has been designed, manufactured and tested to separate the humidity normally contained in
compressed air only. Any other use has to be considered improper. The manufacturer will void the
warranty and not be held responsible for any problem arising from improper use. The correct use requires
adherence to installation conditions specified in this manual. THIS UNIT IS NOT DESIGNED FOR
RESIDENTIAL USE.
This dryer is supplied tested and fully assembled. The only operation left to the user is the connection to
the plant in compliance with the instructions given in the following chapters.
The purpose of the machine is the separation of water and eventual oil particles present
in compressed air.
operations leading to direct contact with foodstuff without proper filtration per local and
federal regulations. Please consult your distributor for further information.
RECEIVING EQUIPMENT
Immediately upon receipt of equipment, remove all crating and packaging around equipment. Examine
machinery for any damages either external or internal that may have occurred in transit.
If there is any physical damage or a refrigerant leak, (suction/analyzer gauge reads zero) please note
all damages on bill of lading during delivery or file claim immediately with shipper if damage is detected
after delivery. Ask for a local terminal phone number to report all damages to the Transportation
Company. The carrier is legally responsible for any damages, since the unit is shipped F.O.B.
INSTALLATION LOCATION AND PIPING
Particular care is required in selecting the installation site, as an improper location could
jeopardize the proper operation of the dryer. This unit is not suitable to be used in an
explosive atmosphere, or where the risk of fire could be present.
The unit should be installed in an area that is clean and dry, allowing sufficient space on all sides for
routine maintenance and service. It should be located on a level floor or shelf free from vibrations and
sufficient to support the total weight of the machinery. Although the dryer package is a freestanding unit,
it may be secured by bolting the base to the floor but is not required. This standard dryer is designed
for indoor installation. Contact distributor if installing unit outdoors.
Installations at altitudes above 4000 feet (1219 meters) may require adjustments. The unit has been
factory adjusted to operate up to 4000 feet (1219 meters), and if installation is above this altitude, contact
the factory service department for correct refrigerant settings.
Air-Cooled Units
Position the unit to permit free circulation of cooling air to the dryer. All the free air vents on the dryer
must be two feet, minimum from obstructions preventing flow to and from the unit. The unit should be
shielded from direct sunlight, weather elements, and hot discharge air from other air-cooled equipment.
The ambient temperature around the dryer must not exceed 100°F (37.7°C) or be less than 50°F (10°C).
Ambient temperatures below 50°F (10°C) require optional equipment specified below.
Sufficient ventilation must be provided to maintain acceptable ambient for efficient operation. Consider
heat rejection when locating dryer.
Water-Cooled Units
The fluid coolant temperature supplied to the refrigerant condenser must not exceed 90°F(32.2°C). The
fluid supply lines to the condenser should be sized to deliver the required flow of coolant. If the ambient
temperature exceeds the supply fluid temperature by 10°F, insulate the inlet line to the condenser. For
maximum efficiency filter with 20 mesh strainer and treat the fluid supply to the condenser.
STARTUP PROCEDURE WATER COOLED
The unit is supplied with a water-regulating valve at the outlet of the refrigeration condenser. This valve
modulates water flow to maintain a stable refrigerant discharge pressure of 250-275 PSIG for R-404a
units and 125-145 PSIG for R-134A units. If the refrigeration discharge pressure maintains a pressure
above or below this setting, adjustments will be required to the water-regulating valve. Contact a qualified
refrigeration service technician or the Great Lakes Service Department.
