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 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 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 been

shown 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 sys-

tems.

Additional health and safety information may be obtained

from 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-134a refrigerant Recovery/

Recycling/Charging System. (If the system has been

open for several days, the receiver/dryer should be

replaced, and the system should be evacuated for

several hours.)

2. Connect a R-134a refrigerant Recovery/Recycling/

Charging System to the vehicle, as shown, follow-

ing the equipment manufacturer's instructions.

NOTE: If low-pressure does not reach more than 93.3

kPa (700 mmHg, 27.6 in.Hg) in 15 minutes, there is

probably a leak in the system. Partially charge the

system, and check for leaks (see Leak Test).

Battery

Test

Battery fluid (electrolyte) contains sulfuric acid. It may cause severe burns if it gets on your skin or in your eyes. Wear

protective clothing and a face shield.

— If electrolyte gets on your skin or clothes, rinse it off with water immediately.

— If electrolyte gets in your eyes, flush it out by splashing water in your eyes for at least 15 minutes; call a physician

immediately.

A battery gives off hydrogen gas. If ignited, the hydrogen will explode and could crack the battery case and splatter

acid on you. Keep sparks, flames, and cigarettes away from the battery.

Overcharging will raise the temperature of the electrolyte. This may force electrolyte to spray out of the battery vents.

Follow the charger manufacturer's instructions, and charge the battery at a proper rate.

Use either a JCI or Bear ARBST tester, and follow the manufacturer's procedures. If you don't have one of these comput-

erized testers, follow this conventional test procedure:

To get accurate results, the temperature of the electrolyte must be between 70°F (21°C) and 100°F (38°C).

Check For Damage

If the case is cracked or the posts are loose, replace

the battery.

Check Indicator EYE Color

If the indicator shows low electrolyte, add distilled

water if possible.

EYE Indicates OK
EYE Indicates LOW

CHARGE

Test Load Capacity (#1)

Apply 300 amp load for 15 seconds to remove

surface charge.

Allow 15 seconds recovery period.

Apply test load (see Test Load Chart).

Record voltage at the end of 15 seconds.

Stays above 9.6 volts;

battery is OK.
Drops below 9.6 volts.ProCarManuals.com
