equipment that is U.L.-listed
and
is
cer-
tified to meet the requ irements
of
SAE J2210 to remove
HFC-134a
IR-134al
from the
air conditioner system.
CAUTION: Exposure to air conditioner refrigerant and
lubricant vapor or mist can irritate eyes, nose and
throat. Avoid breathing the air conditioner refrigerant
and lubricant vapor or mist.
If accidental
system
discharge occurs,
ventilate
work
area before
resuming service. Additional
health and
safety
information may be obtained
from
the refrigerant
and lubricant manufacturers.

service equipment
that
is
U.l.-listed and is
cer-
tified to
meet
the requirements
of
SAE J2210 to remove

CAUTION: Exposure to air conditioner refrigerant and
lubricant vapor or mist can Irritate eyes, nose and throat.
Avoid breathing the air conditioner refrigerant and lubri-
cant vapor or mist.
If accidental system discharge
occurs,
ventilate work
area before resuming
service.
R-134a service equipment or
vehicle
air
conditioner
sys-
tems should not be pressure
tested or
leak tested with
compressed air.
Some mixtures of air and R-134a have
to be combustible at elevated pressures
and can result in fire or explosion causing injury or
property damage. Never use compressed air to pressure
test R-134a service equipment or vehicle air conditioner
systems.
Additional health and safety information may be obtained
from the refrigerant and lubricant manufacturers.
1.
Connect a R-134a refrigerant recovery!recycling!
charging
station to the
vehicle,
as shown in the pre-
vious column,
following the
equipment manufactur-
er's instructions
.
2.
Open the high-pressure valve to
charge
the
system
to the
specified capacity,
then
close
the
supply
valve,
and remove the
charging system couplers.
Select the
appropriate
unit
of
measure for

0.70 to 0.75 kg
1.5 to 1.6Ibs.
24.7 to 26.5 oz.
3.
Check the
system
for
leaks
using
a
R-134a refriger-
ant leak detector with an accuracy of 14 9 (0.5 oz)
per year
or
bener.
4.
If
you
find leaks that require the
system
to
be
opened
(to repair
or
replace
hoses, fittings,
etc.), recover the
system
according
to the Recovery Procedure on page
22-59.
5.
After checking
and repairing
leaks, the system must
be evacuated
(see
