INTRODUCTION
1.0 General Service and Safety Precautions
WARNING
Never service, repair, or troubleshoot this system unless you are a professional air conditioning/refrigeration
service person. Improper servicing can lead to serious injury or death from fire, electric shock, or explosion.
Refrigeration and air conditioning devices are extremely complicated by nature. Servicing, repairing, and
troubleshooting these products should be done only by those with the necessary knowledge, training, and
equipment.
1.1 Refrigerants and Other Chemicals
Contact with refrigerant, mixtures of refrigerant and oil, or other chemicals can cause a variety of injuries
including burns and frostbite. For example, if refrigerant contacts skin or eyes it can cause severe frostbite.
Also, in the event of a compressor motor failure, some refrigerant and oil mixtures can be acidic and cause
chemical burns.
To avoid injury, wear appropriate protective eye wear, gloves, and clothing when servicing an air
conditioning or refrigeration system. Refer to your refrigerant supplier for more information.
If refrigerant or mixtures of refrigerant and oil come in contact with skin or eyes, flush the exposed area
with water and get medical attention immediately.
1.2 System Flushing, Purging, and Pressure Testing for Leaks
Failure to properly flush, purge, or pressure test a system for leaks can result in serious injury or death from
explosion, fire or contact with acid-saturated refrigerant or oil mists.
Webasto recommends that the system be serviced using a flush and purge station such as a Robinair®
unit or similar equipment designed for R134a refrigerant systems.
Follow these precautions when flushing/purging a system or pressure testing a system for leaks:
• Use flushing products according to the manufacturer’s instructions.
• To purge a system, use only dry nitrogen.
• When pressure testing for leaks, use only regulated dry nitrogen or dry nitrogen plus trace amounts
of the serial label refrigerant, in this case, R134a.
• When purging or pressure testing any refrigeration or air conditioning system for leaks, never use air,
oxygen or acetylene. Oxygen can explode on contact with oil.
• Acetylene can decompose and explode when exposed to pressures greater than approximately 15
PSIG.
• Combining an oxidizing gas, such as oxygen or air, with an HCFC or HFC refrigerant under pressure
can result in a fire or explosion.
• Use a pressure regulating valve and pressure gauges.
Commercial cylinders of nitrogen contain pressures in excess of 2000 PSIG at 70°F. At pressures much
lower than 2000 PSIG, compressors can explode and cause serious injury or death. To avoid over
pressurizing the system, always use a pressure regulating valve on the nitrogen cylinder discharge. The
pressure regulator must be able to reduce the pressure down to 1 or 2 PSIG and maintain this pressure. The
regulating valve must be equipped with two pressure gauges:
• one gauge to measure cylinder pressure, and
• one gauge to measure discharge or down-stream pressure.
In addition to a pressure regulating valve and gauges, always install a pressure relief valve. This can also be
a frangible disc type pressure relief device. This device should have a discharge port of at least 1/2” MPT
size. The valve or frangible disc device must be set to release at 175 PSIG.
• Do not pressurize the system beyond 150 PSIG field leak test pressure. When field testing a system
for leaks, 150 PSIG is adequate test pressure.
• Disconnect nitrogen cylinder and evacuate the system before connecting the refrigerant container.
Disconnect the nitrogen cylinder and release the pressure in the system before connecting a
refrigerant container to the system. The higher pressure gas in the system can explode the refrigerant
container.
1.3 Scope
These non-binding installation instructions are intended to support trained or certified dealers, and
personnel in the installation of the Webasto VAC / HVAC unit. Provided these instructions are followed
properly and all options listed in the parts breakdown are installed, this system will provide supplemental
heating and cooling.
1.4 Applicability of Manual
These non-binding installation instructions apply to the make/model listed on the front cover of this
installation manual. Due to optional equipment, there may be build variations between this installation
manual and the vehicle you are working on. Technical modifications that differ from the instructions set
forth exclude all liability claims. Acknowledged engineering conventions must be observed for the
installation work. Carefully read all documentation prior to installation.
CAUTION
Location of the Webasto provided components, wiring and control devices are important for proper
operation. Failure to comply with the installation guidelines provided may result in poor operation or
damage to the Webasto unit, the vehicle, or vehicle components.
Non-compliance with the installation instructions and information contained therein will void the warranty.
The same applies for repairs performed by untrained personnel and repairs not using original equipment
spare parts.
1.5 Meaning of Warnings, Cautions and Notes
WARNING:
This heading is used to highlight that non-compliance with instructions or procedures may cause injuries or
lethal accidents to personnel.
CAUTION :
This heading is used to highlight that non-compliance with instructions or procedures may cause damage to
equipment.
NOTE:
This heading is used to highlight and draw specific attention to information.
1.6 Safety
All relevant state and provincial regulations, if any, governing the installation of this device must be
observed! The general safety regulations for the prevention of accidents and the relevant operating safety
instructions must be observed at all times.
1.7 Legal Provisions for Installation
EPA regulations stipulate that all vehicles requiring the removal of refrigerants be serviced by a certified
technician under section 609 of the Clean Air Act and that all refrigerant be reclaimed and recycled.
Vehicle operation must not be impaired due to any Webasto installed components. All power circuits must
be fused with an appropriate fuse or circuit breaker.
1.8 Prohibition on Venting
Section 608 of the Clean Air Act prohibits individuals from intentionally venting ozone-depleting substances
used as refrigerants (generally CFCs and HCFCs), and their substitutes (such as HFCs) into the atmosphere
while maintaining, servicing, repairing, or disposing of air-conditioning or refrigeration equipment.
1.9 Installation General References
• Bare sheet metal, for example around drilled holes, must be treated with anti-corrosive coating.
• Secure hoses, cables and wiring harnesses with cable ties and fit protective hoses around them at
chafing points.
• Fit edge protectors (split fuel hose, grommet, split-loom, etc.) to sharp edges.
• Replace hose clamps as necessary. Hose clamps should be inspected before re-use. Look for
damage to the screw and to the band due to fatigue, corrosion, or improper installation.
