WARNING: Personal injury can result
from contact with refrigerant.
Contact with refrigerant can cause
frostbite. Keep face and hands away to
help prevent injury.
Protective goggles must always be worn
when refrigerant lines are opened even if
the gauges indicated the system is empty
of refrigerant.
Always use precaution when a fitting is
removed. Slowly loosen the fitting. If the
system is still under pressure, release it
slowly in a well ventilated area.
Do not smoke when servicing air
conditioners or wherever refrigerant gas
may be present.
Inhaling air conditioner refrigerant gas
through a lit cigarette or other smoking
method or inhaling fumes released from a
flame contacting air condition refrigerant
gas, can cause bodily harm of death.
Use a certified recovery and recycling cart
to properly remove the refrigerant from the
air conditioning system.
NOTE: Put identification marks on all hoses, hose
assemblies, wires, and tube assemblies for
installation purposes. Any engine openings
such as turbo charger, intake manifold ports
and coolant ports should be plugged or capped
while their respective tubes, hoses and any
other connections are removed. Plugging
prevents fluid loss and helps keep contaminants
from entering the system.
NOTE: Cleanliness is an important factor. Thoroughly
clean exterior of components prior to
disassembly to prevent dirt from entering
internal mechanisms. Precision components
can be damaged by contaminants or dirt.
Perform disassembly procedures on a clean
work surface. Keep components covered and
protected at all times.
NOTE: Care must be taken to ensure fluids are
contained during performance of inspection,
maintenance, testing, adjusting and repair of
the machine. Be prepared to collect the fluid
with suitable containers before opening any
compartment or disassembling any component
containing fluids.
Dispose of all fluids according to local
regulations and mandates.
NOTE: Only a certified technician with certified
equipment is allowed to service the air
conditioning system.
