LIMITED WARRANTY AGREEMENT
Puregas Air Dryers carry a one-year warranty against defective workmanship and material.
This period starts at the date of shipment. Not included are the components subject to normal
replacement during a year’s operating time. These parts include, but are not limited to;
electrical components, pressure switches, pressure regulators, and air compressors which
carry a one-year warranty.
On refrigeration type air dryers, the basic refrigeration circuit carries a five-year warranty.
This warranty covers the refrigeration compressor, refrigeration tubing and coils but NOT the

MODEL P05860-GLTG
NITROGEN BOTTLE REPLACEMENT MODULE
SECTION 1 -GENERAL
This instruction manual covers the description, installation, operation, maintenance and,
service part identification for the P05860-GLTG Nitrogen Bottle Replacement Modules
(NBRM). The P05860-GLTG are self-contained, assembled and tested units, designed to
effectively replace the nitrogen bottle for dry air buffering and pneumatic tool applications.
The P05860-GLTG models can be installed in a nitrogen bottle rack in a truck.
The ratings, characteristics and features for the Nitrogen Bottle Replacement Module are
specified below.
NITROGEN BOTTLE REPLACEMENT
CHART 1
MODULE SPECIFICATIONS
Specifications

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.

SECTION 4 - GENERAL MAINTENANCE
4.1 Nitrogen Bottle Replacement Module
The Nitrogen Bottle Replacement Module requires minimal maintenance. The following
paragraphs provide procedures for routine maintenance of various parts. If further assistance
is required, contact, Puregas Technical Service Department at
1-800-521-5351 or [phone].
The tank pressure MUST BE RELEASED before attempting to service any components.
Use either the drain valve, or the tank relief valve on the air tank.
Check the following:
9Safety valve - Refer to Paragraph 4.2.
9Pressure Switch - Refer to Paragraph 4.3.
9Install Compressor Maintenance Kit (P07102) - Refer to Paragraph 4.5.
9Check all wire connections.
9Soap test all pressure fittings.
CAUTION!!!
Release all tank pressure using either the drain valve or the
Tank relief valve prior to servicing any components.
CAUTION!!!
DISCONNECT POWER When working around energized circuits,
extreme caution should be taken to prevent injury to
personnel and damage to equipment.
CAUTION!!!
It is very important that routine maintenance be performed on the
compressor each year, or every 4,000 hours.

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.
