A/C Service Tips and Precautions

4.
5.
6.

Always disconnect the negative cable from the battery whenever replacing air conditioner parts.
Keep moisture and dust out of the system. When disconnecting any lines, plug or cap the fittings immediately; don’t
remove the caps or plugs until just before you reconnect each line.
Before connecting any hose or line, apply a few drops of refrigerant oil to the O-ring.
When tightening or loosening a fitting, use a second wrench to support the matching fitting.
When discharging the system, use a refrigerant recovery system; don’t release refrigerant into the atmosphare.
And refrigerant oil after replacing the following parts:
Condenser . . . . . . . . . . . . . . . . . . . . . . . . 10 cc (l/3 fl oz)

compressor: 80 cc (2 2/3 fl OZ)-Volume of oil from removed compressor=Volume
to drain from new compressor.

Don’t overtighten fittings; you could damage them. Leaks are caused by faulty O-rings, overtightening won’t stop them.

When handling refrigerant (R-12):
0 Always wear eye protection.
l Do not let refrigerant get on your skin or in your eyes. If it does:
- Do not rub your eyes or skin.
- Splash large quantities of cool water in your eyes or on your skin.
- Rush to a physician or hospital for immediate treatment. Do not attempt to treat it yourself.
l Keep refrigerant containers (cans of R-12) stored below 40°C (100°F).
l Do not handle or discharge refrigerant in an enclosed area near an open flame; it may ignite and produce a poisonous
gas.
l The ozone is fragile layer surrounding the earth which acts as a shield against the sun’s ultraviolet radiation. Chlorine from chemicals called chlorofluorocarbons (CFCs) destroy the ozone in the stratosphere. Automotive air conditioning systems currently use chlorofluorocarbons as the refrigerant. Auto air conditioning service equipment
has been developed to minimize the release of CFCs to the atmosphere. All service procedures should be performed using this equipment and the manufactuer’s instructions.

Troubleshooting
-Troubleshooting Precautions
0 Push the locking tab to disconnect.

Before
Troubleshooting
0 Check the main fuse and the fuse box.
0 Check the battery for damage, ‘state of charge, and
clean and tight connections.
0 Check the alternator belt tension.
CAUTION:
0 Do not quick-charge a battery unless the battery
ground cable has been disconnected, or you will
damage the alternator diodes.
0 Do not attempt to crank the engine with the battery ground cable connected incompletely or
you will severely damage the wiring.
While You’re Working
l Make sure connectors are clean, and have no loose
pins or receptacles.
0 Make sure multiple pin connectors are packed with
grease (except watertight connectors).

LOCKING TABS

Since new type connectors are used, connection and
disconnection of them should be done paying attention
to the following precautions.
0 Because all the connectors except terminal of 1-P
are equipped with push-down type locks, unlock
them first before disconnecting the connectors.
0 On the connectors installed on the bracket a pull
type lock is equipped between the bracket and the
connector.
Some connectors of this type can not’ be disconnected unless they are removed from their brackets.
,’ When disconnecting, check their shapes.
0 On the bracket mounted connector with dual locks,
remove the connector from the bracket before
disconnecting.

For the connector which uses insulation grease,
clean the connector then apply grease if the grease is
insufficient or contaminated.

0 Before connecting, check each connector cover for
damage. Also make sure that the female connector
is tight and not loosened from the previous use.

0 Insert male connectors into the female connectors
fully until they will no longer go.
l

0 Insert the connector tightly and make sure it is
securely locked.

0 Position the wires so that the open end of the cover
faces down.

0 Check all the wire harnesses are connected.
0 There are two types of locking tab: one that you
have to push and the other you should not touch
when connecting the connector. Check the shape of
the locking tab before connecting.

Troubleshooting
- Five-Step Troubleshooting
1.

Verify The Complaint
Turn on all the components in the problem circuit to
verify the customer complaint. Note the symptoms. Do not begin disassembly or testing until you
have narrowed down the problem area.

2.

4. Fix The Problem
Once the specific problem is identified, make the
repair. Be sure to use proper tools and safe
procedures.

Analyze The Schematic
Look up the schematic for the problem circuit.
Determine how the circuit is supposed to work by
tracing the current paths from the power feed
through the circuit components to ground. If
several circuits fail at the same time, the fuse or
ground is a likely cause.

5.

Based on the symptoms and your understanding of
the circuit operation, identify one or more possible
causes of the problem.
3.

Isolate The Problem By Testing The Circuit
Make circuit tests to check the diagnosis you made
in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting. Test
for the most likely cause of failure first. Try to make
tests at points that are easily accessible.

23-8
vnx.su

Make Sure The Circuit Works
Turn on all components in the repaired circuit in all
modes to make sure you’ve fixed the entire problem. If the problem was a blown fuse, be sure to
test all of the circuits on that fuse. Make sure no
new problems turn up and the original problem
does not recur.
