INSTALLATION
Inspect the dryer upon receipt for any damage that may have occurred during shipment.
Each desiccant dryer is supplied with a User Manual, dryer general arrangement drawing, and ASME pressure
vessel U1A data reports (where applicable).
The initial charge of desiccant is included with the dryer. Ensure vessels are filled with desiccant prior to startup.
Models 2001 and larger include desiccant shipped separately in 25 lb bags to be installed by the user at the site.
Smaller dryers are shipped with desiccant installed.
Exhaust mufflers are supplied for each dryer. A quantity of two mufflers are shipped attached to the dryer, unin-
stalled, for models 201 and larger. Mufflers should not be installed until after startup to allow excess desiccant dust
to be cleared from the dryer and not prematurely clog the new mufflers.
The dewpoint sensor (optional) is shipped in a small container attached to the dryer. Take care not to misplace
before installing.
If placed in storage, place in a location protected from the environment. If stored outside, it is recommended that the
dryer be underneath a shelter and be shrink wrapped or crated to protect against rain. Desiccant dryers should not
be stored in a location exposed to freezing temperatures or direct sunlight. Dryers designed for outdoor use should
not be placed outside until ready for operation. All plugs and flange covers should remain in place until the dryer is
ready to be installed. Desiccant bags should remain in original closed packaging and be stored in a dry environment
until dryer is ready for operation. Dryers with desiccant installed should be stored in a dry environment.
The dryer should be moved using a pallet jack or fork truck. Desiccant dryers are tall and top heavy. Use caution
while moving the equipment to avoid tipping over. Many dryers have desiccant vessels equipped with lifting lugs.
DO NOT USE THE VESSEL LIFTING LUGS TO LIFT THE DRYER. They are only used to lift an empty vessel and are
not designed to hold the weight of the equipment.
Install in an area with an ambient temperature range of 40°F to 100°F. The area should be well lit and ventilated. It is
recommended to leave a minimum of four feet around all sides of the dryer for maintenance. Ensure that the dryer is
stable and properly secured on a vibration free floor before operation.
If installed outdoors, the desiccant dryer should be installed in an area protected from the effects of weather.
Locate under a roof if possible. Avoid direct sunlight so that the control display does not become damaged and can
be clearly read. If installed in an area with below freezing temperatures, proper heat trace and freeze protection must
be added to the equipment.
