Air Conditioner System Refrigerant Recovery - New Holland T8010 Manual

AIR CONDITIONER SYSTEM REFRIGERANT RECOVERY

IMPORTANT: There are no repair procedures for the compressor or compressor clutch. If the clutch or
compressor are defective, replace them.
WARNING: 134a is the only refrigerant
approved in 134a systems. Alter native
refrigerants which boast better cooling
!
c apabilities are in most c ases highly
flammable. Do not expose contaminated
refrigerant to spark, flame or yourself.
IMPORTANT: Refr igerant contamination has
become an issue since the introduction of 134a as a
replacement for R-12. Contamination refers to a
refrigerant blend and/or mixture of alternative
refrigerants and 134a. Typically, R-12 systems which
are in need of repair or recharge are suspect to
refrigerant contamination due to the number of so
called "drop-in" replacements or substitutes for 134a.
Systems designed for 134a, such as the MX
MAGNUM, may be at lower risk for contamination,
bu t p r e c a u t i o n s s h o u l d b e t a ke n t o p r eve n t
contamination of service equipment and/or other A/C
systems.
IMPORTANT: A refrigerant identifier should be used
to determine refrigerant contamination prior to
recover y. It is recommended to use OEM4450
refrigerant identifier. If a refrigerant contamination
level of 2% or greater is discovered, do not recover
the system to a tank with pure 134a refrigerant.
Recover only to a tank reserved for contaminated
refrigerant with the air-powered station - OEM1691.
WARNING: OEM1415, and its predecessor
OEM1418, were designed for the recovery
and recycling of pure 134a refrigerant. Do
NOT use OE M1415 and O EM1418 to
!
recover contaminated refrigerant; you will
void your warranty, you may damage the
compressor and filter-drier in the recovery
station, and you may expose yourself to the
danger of an explosion.

WARNING: If the refrigerant identifier
indicates the system contains more than 2%
hydrocarbon (propane, butane or isobutane),
the system and its contents must be treated
as flammable; if more than 4% hydrocarbon,
the system and its contents must be treated
as explosive. Do not operate the vehicle or

contaminated refrigerant with an electric-
powered unit (OEM1415 or OEM1418). Use
the air-powered station - OEM1691 - to
recover this refrigerant. Avoid heat, sparks
and open flame when working with this
contaminated refrigerant.
I M P O RTA N T: I f c o nt a m i n a t e d r e f r i g e r an t i s
discovered and recovered with OEM1691, replace
the receiver-drier in the tractor being serviced
BEFORE you recharge the system with pure 134a
refrigerant. OEM1415 or OEM1418 should be used
to evacuate and recharge the system after the
contaminated refrigerant has been safely recovered.
NOTE: Check with your local environmental agency
for regulations on the
contaminated refrigerant.
NOTE: In the United States, EPA regulations require
that tanks of contaminated refrigerant be sent to a
refrigerant reclaimer for the contents to be purified or
destroyed. Call 1-800-296-1996 to locate a reclaimer
in your area.
WARNING: Do NOT use a tank without a

refrigerant with OEM1691. The limit switch
prevents overfilling the tank and protects
your safety.
WARNING: When working with SP-20 PAG
oil, follow these safety precautions: 1) Avoid
contact with eyes, skin and clothing. 2) Avoid
breathing vapor, aerosol and mist. 3) Do not
