Proper Use Of The Dryer; Receiving Equipment; Installation, Location And Piping - Gardner Denver GSRN Series Instruction Manual

This dryer has been designed, manufactured and tested to separate humidity normally contained in
compressed air only. Any other unauthorized use will 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 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.

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. If damage is detected after the equipment delivery; contact
the local terminal to report all damages and file a claim immediately with the transportation company. The
carrier is legally responsible for any damages, since the unit is shipped F.O.B.
INSTALLATION LOCATION PIPING & CONNECTION
Particular care is required in selecting the installation site, as an unsuitable 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) will experience a loss of capacity and may require
field adjustments of pressure settings. The unit has been factory adjusted to operate up to 4000 feet (1219
meters), and if installation is above this altitude, contact your local distributor for correct refrigerant settings.
Air-Cooled Units
Allow (2') two feet, minimum clearance around the dryer for maintenance access and adequate free
circulation of cooling air to the dryer. The ambient temperature around the dryer must not exceed 110°F
(37.7°C) or be less than 40°F (10°C).
Water-Cooled Unit & Y-Strainer Installation
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. Cooling
fluid quality should be well maintained with proper water treatment and a low differential across the inlet
filtration. If cooling supply lines are exposed to ambient that exceed the fluid temperature by 10°F the
addition of insulation will help maintain the fluid cooling capacity.

pH
Ambient temperatures below 40°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.
