SECTION 2 - INSPECTION AND INSTALLATION
2.1 Initial Inspection
Before installing unit, carefully inspect for shipping damage.
2.2 Installation
The module must be installed inside the vehicle compartment to prevent weather damage. The
optimum operating temperature range is between 40 to 95 oF. Although the unit will operate at
higher temperatures, the operating life of the compressor decreases dramatically.
2.3 Electrical Requirements
Refer to Chart 1 for product specific electrical requirements. The recommended generator size
is 4.0 kW. Refer to Figures 1, 2, and 3 for electrical hookup.
Figure 1
WIRING DIAGRAM
NOTE:
Shipping damage must be brought to the immediate attention of the carrier.
CAUTION!!!
Condensation in the storage tank must be drained to prevent freezing.
NOTE:
Adequate power is required for ALL equipment being used when
using a portable generator.

SECTION 3 - PRINCIPLES OF OPERATION
3.1 Air System
The air flows from the air compressor to the storage tank and then to the air buffering dryer.
Drying steps involved are summarized as follows:
3.2 Air Compressor
Ambient air is drawn through the intake filters of the air compressor and is compressed to
approximately 80-110 PSIG in the storage tank.
3.3 Pressure Switch, and Safety Relief Valve
The air pressure in the storage tank is controlled by the unloader pressure switch. The
pressure switch starts the air compressor at 80 PSIG and stops it at 110 PSIG. This unloader
pressure switch releases the static air from the air compressor discharge line, allowing for
easy start-up. The inline check valve prevents the air from flowing out of the tank back
through the compressor after the compressor has shut off. The tank pressure safety relief
valve is factory preset to prevent pressure building above 165 PSIG.
3.4 Air Buffering Dryer
Air now flows from the air storage tank to the air buffering dryer which uses silica gel to
remove the moisture. The silica gel is dry when it is a blue color. If the silica gel turns pink,
it must be replaced. Refer to Figure 7.
3.5 Manual Drain Valve
The manual drain provides a means of draining water from the storage tank. The water
should be drained each day after the unit has been in service.
3.6 Water Drain Instructions
With at least 20 PSIG pressure in the storage tank, slowly open the water drain valve
allowing water to drain from tank; close the water drain valve when all moisture or water has
drained. Repeat Procedure as needed. Refer to Figure 7.
NOTE:
Never operate system with the safety relief valve removed from the tank.
DO NOT make adjustments to this valve. This is an A.S.M.E. requirement and
MUST NOT be tampered with.
NOTE:
Important to keep tank drained under freezing conditions.

4.2 Air Compressor Safety Valve
The air compressor safety valve, located on the head of the air compressor, is factory preset
to prevent the air compressor from delivering air over 115 PSIG(+/- 2 PSIG). Check for
proper operation. If adjustment is required, use the following procedure while the
compressor is operating.
A. Adjust pressure switch cut out to 115 PSIG. Refer to Figure 5.
B. Referring to Figure 6, loosen the safety valve lock nut and adjust the nut until the
maintained pressure is 115 PSIG and the relief valve is releasing air.
C. Allow the compressor to cycle through the cycling pressure range several times and
soap test to insure the safety valve is tight and does not leak.
D. If the safety valve is defective and requires changing, always check replacement
valve for proper adjustment.
E. Readjust air compressor pressure switch cut out to 110 PSIG.
4.3 Air Compressor Pressure Switch
The pressure switch is factory set to stop and start the air compressor and maintain the
pressure in the air storage tank. The pressure in the air storage tank will cycle between 80
PSIG(+/- 2 PSIG) and 110 PSIG(+/- 2 PSIG) as noted on the tank pressure gauge. To adjust
the ON/OFF pressure switch, refer to Figure 5 below.
Step 1: Turn clockwise to increase
both cut-out and cut-in pressure.
Step 2: Turn clockwise to increase
cut-out pressure without affecting
cut-in pressure.

4.5 Air Compressor Maintenance
The P07102 maintenance kit contains parts necessary for scheduled routine maintenance on
the nitrogen bottle replacement module when operated under normal conditions. Refer to
Figure 6. The contents of the maintenance kit are as follows:
If the air compressor shows evidence of overheating or excessive noise, stop immediately for
repairs.
Regular inspection may prevent expensive repairs. The rider ring thickness can indicate
when the air compressor needs maintenance. If a rider ring measures .055 inches or less in
thickness, the maintenance kit, P07102 should be installed. The thickness of a new rider ring
is .060 inches.
The wear of the air compressor rings are affected by ambient conditions. At 80 oF. maximum
ambient temperature and relative humidity 40% maximum average, it is suggested the
compressor life between maintenance be approximately 4,000 hours of run time.
The air compressor is oilless and requires no lubrication. It is recommended the piston rings,
piston seals, rider rings, inlet valves, valve plates and gaskets be replaced at 4,000 hours of
run time.

SECTION 5 – TROUBLESHOOTING INFORMATION GUIDE
This troubleshooting guide is set in a columnar format to simplify the isolation of problems,
possible causes, areas to check and corrective action required to restore the air dryer to normal
operation. It is further divided into system headings for easy referral. Where possible, the most
likely causes have been listed first. Otherwise, the causes start with the simplest and progress to
more complicated possibilities. The steps should be followed in sequence to expedite service. It
is further suggested that once the problem has been isolated, the corresponding text in the
Maintenance Section be reviewed to provide additional information.
This guide will require a volt ohmmeter (VOM), and will specify DC (direct current) or AC
(alternating current) setting.
The troubleshooting information guide can by no means cover every possible cause of
malfunction, but will help solve most problems. If the problem persists after thoroughly
consulting the troubleshooting section, contact
Puregas Technical Service Department at 1-800-521-5351 extension 2156, or (303) 657-2156.
