1999 HONDA CR-V Service manual

Recovery
Use only service equipment that is U.L.-listed and is cer-
tified to meet the requirements of SAE J2210 to remove
HFC-134a (R-134a) from the air conditioner system.
CAUTION: Exposure to air conditioner refrigerant and
lubricant vapor or mist can irritate eyes, nose and
throat. Avoid brqathing the air conditioner retrigerant
and lubricant vapor or mist.
lf 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 arr.
@@ some mixtures of air and R-134a have been
shown to be combustible at elevated plessures and can
result in fire or explosion causing iniury or property dam-
age. Never use compressed air to pressure tect R-134a
service equipment or vehicle air conditioner systems.
Additional health and safety intormation may be obtained
from the refrigerant and lubricant manufacturers.
'1. Connect a R-134a refrigerant recove rylrecycling/
charging station to the vehicle, as shown, following
the equipment manufacturer's instructions
2. Measure the amount of refrigerant oil removed trom
the A,/C system after the recovery process is com-
oleted. Be sure to install the same amount of new
refrigerant oil back into the AVC system before charg-
inq.

A/C System Service
Evacuation
Use only service equipment that is U.L.-listed and is cer-tified to meet the requirements of SAE J2210 to removeHFC-134a {R-134a)from the air conditioner system.
CAUTION: Exposure to air conditioner refrigerant andlubricant vapor or mist can irrhate eyes, noso and throat.Avoid breathing the air condhioner retrigerant and lubri-cant vapor or mist.
lf accidental system discharge occu.s. ventilate workarea before resuming service.
R 134a service equipment or vehicle air conditioner sys-tems should not be pressure tested or leak tested withcompressed arr.
!@ some mixtures of air and R-134a hsvo beenshown to be combustible at elevated pressures and canresult in tire or explosion causing iniury ot property
damage. Never use compressed air to pressure test R-134a service equipment or vehicle air conditioner svs-tems.
Additional health and safety information may be obtainedfrom the refrigerant and lubricant manufacturers.
1, When an A,/C System has been opened to the atmo-
sphere, such as during installation or repair, it must
be evacuated using a R-l34a refrigerant recovery/
recycling/charging station. {lf the system has beenopen for several days, the receiver/dryer should bereplaced, and the system should be evacuated forseveral hours.)
Connect a R-134a refrigerant recovery/recyclin g/
charging station to the vehicle, as shown, following
the equipment manufacturer's instructions.
Evacuate the system,
lf the low-pressure does not reach more than 93.3kPa (700 mmHg,27.6 in.Hg) in 15 minutes, there isprobably a leak in the system. partially charge thesystem, and check for leaks (see Leak Test).

Charging
Use only service equipment that is U.L.-listed and is cer-
tified to meet the requirements of SAE J2210 to remove
HFC-134a (R-134a) from the air conditioner system.
CAUTION: Exposure to air conditioner refrigerant and
lubricant vapor or mist can irritate eyes, nose and
throat. Avoid breathing th€ air conditioner refrigerant
and lubricant vapor or mist.
lf accidental system discharge occurs, ventilate work
area before resuming service. Additional health and
safety information may be obtained from the relrigerant
and lubricant manufacturers.
Connect a R-'134a refrigerant recovery/recycling/charging
station to the vehicle, as shown. following the equipment
manufacturer's instructions.
R€covery/Recycling/Charging Station
HIGH-PRESSURESIDE
Add the same amount of new refrigerant oil to system
that was removed during recovery. Use only SP-'10
refrigerant oil.
Charge the system with Required amount of R-134a
refrigerant. Do not overcharge the system; the compres-
sor will be damaged.
Select the appropriate unit of measure for your
charging station.

Leak Test
Use only service equipment that is U.L.-listed and is cer-
tified to meet the requirements of SAE J2210 to remove
HFC-134a (R-134a) from the air conditioner system.
CAUTION: Exposure to air conditionor refrigerant and
lubricant vapor or mist can irritate eyes, nose and throat.
Avoid breathing the air conditioner retrigerant and lubri-
cant vapor or mist.
lf accidental system discharge occurs, ventilate work
area before resuming service.
R-134a service equipment or vehicle ajr conditioner sys-
tems should not be pressure tested or leak tested with
compressed arr.
!@ some mixturos of air and R-1348 have
been shown to be combustible at olovatod pres3uras
and can result in fire or explosion causing iniury or
property damage. Never use comprelised air to pressure
test R-13ila service equipment or vehicle air conditioner
systems.
Additional health and safety information may be obtained
from the refrigerant and lubricant manufacturers.
2.
1.Connect a R-134a refrigerant recove rylrecycling/
charging station to the vehicle, as shown in the pre-
vious column, following the equipment manufactur-
er's instructions.
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 your
charging station.
Refrigerant capacity: 700 to 750 g
0.70 to 0.75 kg
1.5 to 1.6 lbs.
21.7 to 26.5 oz.
Check the system for leaks using a R-134a refriger-
ant leak detector with an accuracy of 14 g (0.5 ozl
per year or better.
lf 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.
After checking and repairing leaks, the system must
be evacuated (see System Evacuation on page 22-601.
