This product can not be modified without the written approval of Tronair, Inc. Any modifications done without written approval
voids all warranties and releases Tronair, Inc., it suppliers, distributors, employees, or financial institutions from any liability
from consequences that may occur. Only Tronair OEM replacement parts shall be used.
1.0 SAFETY INSTRUCTIONS CAUTION!
It is MANDATORY that this instruction manual be read and understood by all persons operating this high
pressure Nitrogen strut service kit.
1.1 GENERAL
Information presented in this manual and on various labels, tags and plates on the unit pertains to equipment design,
installation, operation, maintenance and trouble shooting which should be read, understood and followed for the safe and
effective use of this equipment.
1.2 SAFETY
The Operation, Maintenance, and Trouble Shooting of this high pressure Nitrogen strut service kit requires practices and
procedures which ensure personal operator safety and the safety of others. Therefore, this equipment is to be operated and
maintained only by qualified persons in accordance with this manual and all applicable local codes.
NOTE: Safety instructions specifically pertaining to this kit appear throughout this manual highlighted by the signal
words: WARNING, CAUTION, which identify different levels of hazard.
WARNING! Denote practices which if not carefully followed, could result in serious personal injury and/or
death.
CAUTION! Denote practices which if not carefully followed, could result in minor personal injury or damage to
this equipment.
Nitrogen equipment must be kept clean and free from contaminants at all times. It is imperative that all inspection,
maintenance, testing and servicing of nitrogen system components be done by trained and qualified personnel using approved
procedures.
2.0 OPERATION OF NITROGEN STRUT SERVICE KIT
WARNING
TO AVOID SERIOUS INJURY, LOSS OF LIMB, AND/OR DEATH:
1. DO NOT use high pressure Nitrogen on aircraft components designed for low pressure Nitrogen.
2. DO NOT use with Oxygen or gas other than Nitrogen.
3. DO NOT exceed 1,500 psi inlet pressure.
4. Servicing and maintenance of Nitrogen systems shall be done by only trained and qualified personnel
using approved procedures.
2.1 TRAINING
Read this entire manual prior to operation of the unit. All personnel using this Nitrogen Service Strut Kit should understand and
follow this manual and receive training. We encourage our customers to call Tronair at 800-426-6301 to discuss any operating
or testing requirements.
2.2 GENERAL SAFETY REQUIREMENTS
Pressures: Gasses under pressure are a potential hazard in the form of stored energy. Accidents can occur when this
energy is improperly handled. Be sure that all equipment used is compatible and designed to control the
pressures encountered.
Nitrogen: Nitrogen is chemically stable, non-flammable, and does not support combustion.
Handling: Nitrogen handling must be done with care. The rapid expansion of Nitrogen gas from a high pressure source to
an area of low pressure can produce cryogenic temperatures which could cause severe burns.
2.3 WARNINGS AND CAUTIONS WARNING!
1. DO NOT use on low pressure Nitrogen system or components.
2. If there are any differences between the following instructions and the aircraft maintenance manual,
the aircraft maintenance manual will take precedence.
3. Be sure fill line is secured prior to purging the unit. This will prevent the nose end from whipping
about if too much Nitrogen is allowed to flow through the unit.
CAUTION!
Be sure all valves and controls are in the closed (OFF) position.

3.0 ASSEMBLY INSTRUCTIONS
NOTE: It is recommended Nitrogen servicing procedure should be accomplished in conjunction with Tronair Service
Regulator/Model: 14-6804-6000.
1. Reference Figure 1 during the following steps.
2. Ensure (D) Nitrogen Supply Valve is closed (OFF).
3. Connect (H) Pressure Regulator to Nitrogen supply (not included) if not already connected.
4. Decrease (H) Pressure Regulator to the minimum pressure setting; the regulator adjustment knob is a rotating type.
Clockwise rotation of the knob increases pressure and counter-clockwise rotation decreases pressure.
5. Turn valve handle clockwise to close (A) Air Bleeder Valve.
6. Connect (F) Hose Coupling to (G) Pressure Valve.
7. Ensure (C) Nitrogen Charging Valve is in closed position. (Refer to Aircraft Maintenance Manual)
8. Connect (B) Hose Coupling to (C) Nitrogen Charging Valve.
9. Open (C) Nitrogen Charging Valve. (Refer to Aircraft Maintenance Manual)
10. Turn handle clockwise on (B) Hose Coupling to depress valve core in (C) Nitrogen Charging Valve.
11. Open (D) Nitrogen Supply Valve.
12. Adjust (H) Pressure Regulator until (E) Pressure Gauge reads desired pressure.
3.1 DISASSEMBLY
1. Reference Figure 1.
2. Close (C) Nitrogen Charging Valve. (Refer to Aircraft Maintenance Manual)
3. Turn handle counter-clockwise on (B) Hose Coupling to release valve core in (C) Nitrogen Charging Valve.
4. Close (D) Nitrogen Supply Valve (OFF).
5. Bleed off any excess Nitrogen in gauges and lines by turning valve handle counter-clockwise to open (A) Air Breeder
Valve.
6. Disconnect Pressure Gauge Assembly from strut and Regulator Assembly.

Instrument Certification Notice
The gauge Certificates of Calibration supplied for the gauge(s) on this unit contain the
calibration data for the actual instrument calibrated, along with the calibration date of the
STANDARD used to perform the calibration check.
The due date for re-calibration of the instrument should be based upon the date the instrument
was placed in service in your facility. Re-calibration should be done on a periodic basis as
dictated by the end user's quality system or other overriding requirements.
Note that Tronair, Inc. does not supply certificates of calibration on flow meters or pyrometers
unless requested at the time of placed order. These instruments are considered reference
indicators only and are not critical to the test(s) being performed on the aircraft.
