4.1 LOCATION
WARNING
DO NOT INSTALL THIS DRYER SYSTEM IN AN ENVIRONMENT
OF CORROSIVE CHEMICALS, EXPLOSIVE GASSES, POISONOUS
GASSES, OR SATURATED STEAM HEAT.
Locate dryer system in a protected, well vented area where ambient
temperatures are between 40 o F and 120 o F. Allow sufficient clearance
over and around the dryer system for access to desiccant fill and drain
ports and controls. Refer to SECTION 3.2 for dryer dimensions.
If this dryer system must be installed where ambient temperatures are
below 40 o F, insulation and heat tracing must be properly installed on
the inlet piping, separator, prefilter, purge exhaust line and the
desiccant towers to prevent freezing of the equipment.
Position the dryer system in the upright position on a solid, level,
vibration free surface capable of supporting the dryer system’s weight.
Refer to SECTION 3.1 for dryer system specifications.
The dryer system should not be located in extremely dirty areas where
airborne contaminants can accumulate on the dryer system. If this
cannot be prevented, the dryer system should be cleaned periodically.
An accumulation of dirt on the precooler will greatly reduce its
efficiency. Accumulated dirt may also cause the inlet transfer valve to
fail.

4.3 ELECTRICAL CONNECTIONS
WARNING
SERIOUS PERSONAL INJURY AND DAMAGE TO THE
DRYER SYSTEM WILL OCCUR IF THE DRYER SYSTEM IS
CONNECTED TO A POWER SOURCE OTHER THAN THE
VOLTAGE LISTED ON THE DATA TAG.
Connect the dryer system power cord to a 115V/1PH/60Hz power
source capable of supplying a minimum of 2 AMPS.
4.2 DESICCANT INSTALLATION
The desiccant was factory installed in both towers before the dryer
shipped.
4.5 FILL LUBRICATOR WITH OIL
The lubricator is located in the air line between the regulator and the
pre-cooler air motor. Fill the lubricator with Pneumatic Lubricating Oil
SAE10 AD220 (Van Air p/n 26-7032 quart).
4.4 INSTALLING THE PURGE MUFFLERS
Purge mufflers were shipped separately. They should NOT be installed
until the dryer system has been operated for several hours. From
desiccant installation, some dust may be present in the desiccant
towers. Operating the dryer system with the mufflers installed im-
mediately after the towers have been filled with the desiccant or during
initial start up may cause the mufflers to clog. See SECTION 5.6 for
purge muffler installation.
4.7 CONNECTING THE INLET AND OUTLET
The inlet and outlet of this dryer system are equipped with 2" 4-lug
couplings. Connect the inlet and outlet air hoses to the dryer system.
Remember to use SAFETY CLIPS.
4.6 CONNECT DRAIN LINES
Connect the automatic drains for the separator/prefilter and the prefilter
to an appropriate collection container. Filter and separator/prefilter
discharge may contain compressor lubricants. Comply with all regula-
tions concerning their disposal.
