(5) Take care not to scratch any part of the vehicle.
Bind the tips of tools (clip remover, slot screwdriver etc.)
with a piece of vinyl tape to prevent damage to parts of the
vehicle.
1-4 PRECAUTIONS FOR SAFETY INSTALLATION
(1) Do not proceed with the installation until the battery cables
have been disconnected or a short-circuit may result.
NOTE
1. Always disconnect the NEGATIVE CABLES first.
2. When RECONNECTING the cables, make sure to
connect the positive cable to the positive battery terminal
and the negative cable to the negative battery terminal.
(4) The bolts,nuts and fittings where specified must be torqued
to proper specification. If torque is not specified, refer to
TIGHTENING TORQUE TABLE on page 3.
(3) Use protective covers to avoid damage to the vehicle and
the air conditioning parts.
Seat covers
Fender covers
Floor covers
(2) Do not smoke or expose open flame near the vehicle during
installation.
NOTE
Pay special attention when working on the fuel system.
5
(6) When installing the A/C harnesses, route properly avoiding
interference with surrounding parts.
(7) Do not pull on vehicle wires and/or wire harnesses. To
uncouple electrical connectors, pull only on the connector
itself to avoid damage.
NOTE
In case of lock type connectors, make sure that the
connectors are unlocked before disconnecting.
When re-connecting the connectors, insert them until a
clicking noise is heard. After they are connected, hold
and pull them gently to check that they are connected
properly.
(8) Before making any hose and tube connections, apply a
few drops of compressor oil to the seat of O-ring to avoid
refrigerant leakage.
(9) When removing an O-ring from a tube, use a wooden or
nylon awl to prevent damaging the tube.
NOTE
Always replace the existing O-rings with new ones
specified for refrigerant HFC-134a.
(10)When tightening or loosening fittings, use two wrenches
to prevent the tubes from twisting. After loosening the
fittings, tighten them with specified torque.
6
(11) Do not remove protective caps from fittings until each
component is ready for connection.
NOTE
If the receiver is left uncapped for a long time, the desiccant
inside the receiver may absorb moisture, causing damage
to the air conditioning.
(13)Always keep the refrigerant container (service drum) below
40°C (104 °F).
NOTE
Do not store the refrigerant container in an area where it
can be exposed to direct sunlight, near a source of fire, or
an area such as the inside of a car (the trunk etc.), where
the temperature may become high. Store the container in
a dark place with low-humidity.
(12)When handling refrigerant, always wear proper eye
protection and do not allow it to come in contact with skin.
(14)Do not expose refrigerant to an open flame.
(15)Do not drop compressor oil (ND-OIL 8, 9) onto the vehicle
surface. It causes the discoloration of the vehicles body
surface, or deterioration of the acrylic or ABS plastic
components.
7
(16)Use the refrigerant HFC-134a (R134a).
NOTE
The very different characteristics of refrigerants HFC-134a
(R134a) and CFC-12 (R12) have determined the design
of their respective air conditioning systems. Under no
circumstances allow CFC-12 (R12) to enter an HFC-134a
(R134a) system, or vice versa, because serious damage
could occur.
(19)When recovering refrigerant, use the necessary special
service tools.
NOTE
1. Support the service valve by hand to prevent the tube
from bending when connecting the charging hose.
2. Using a general tool like a screwdriver may cause
refrigerant leak by damaging the service valves.
(17)Use the correct compressor oil.
NOTE
Compressor oil used in pre 1993 vehicles CFC-12 (R12)
air conditioning systems cannot be used in HFC-134a
(R134a) air conditioning systems.
For a swash plate type compressor : 200PG (ND-OIL 8)
For a vane type compressor: 100PG (ND-OIL 9)
(18)Use HFC-134a (R134a) gas leak detector.
NOTE
The CFC-12 (R12) leak detector is not sensitive enough
to detect HFC-134a (R134a).
8
(20)Use manifold gauges for HFC-134a (R134a).
NOTE
1. Manifold gauges
Always use HFC-134a (R134a) dedicated manifold
gauges to prevent CFC-12 (R12) and CFC-12 (R12)
compressor oil contaminating the HFC-134a (R134a)
system.
2. Vacuum pump adapter
(1) By connecting a vacuum pump adapter, the vacuum
pump can be used for both HFC-134a (R134a) and
CFC-12 (R12) air conditioning systems.
(2) Be sure to turn off the manifold gauge valve
immediately after evacuating the system, then switch
off the vacuum pump. If this order is reversed, the
line will be temporarily open to atmosphere.
(21)After installing the drive belt, check the belt tension using
a belt tension gauge DENSO BTG-20 or BORROUGHS
BT-33-73F.
NOTE
1. The belt tension must be measured between the
specified pulleys as indicated in the installation manual.
2. A “New belt” refers to a belt which has been used for
less than 5 minutes of operation.
A “Used belt” refers to a belt which has been used for
more than 5 minutes of operation.
3. The drive belt requires accurate tension adjustment ; a
slack belt is likely to cause the belt to whine, while
excessive tension may result in damage to the bearings
or the idle pulley bracket.
4. After installing the drive belt, make sure it is properly
seated in the grooves of the pulley.
9
1-5 PIPE JOINT PRECAUTIONS
(1) Common to all pipe joints
(a) When connecting pipes, after complete mating (pre-mating)(see the illustration below) tighten bolts or nuts.
Reason : Installation without complete mating often causes slanted installation, pinched O-rings, or scratches on
seal surfaces.
(d) Check that no dust is on the O-ring mating parts.
Also do not touch O-rings with gloves on.
(b) Always apply the specified compressor oil (*) to an O-ring before installing it. However , when resin (such as acrylic
resin or ABS plastic) is in the area, beware of the possibility that oil causes environment al stress cracking to these
resins. Be careful to prevent foreign materials from contaminating the oil.
(*) 10P-type, 7SB, scroll : ND8 T V-type : ND9
(c) Check that an O-ring is installed correctly before mating joints.

(e) Do not add excessive force to pipes. Do not deform pipes.
(f) Arrange hoses well. For example, it is not allowed to
bend or twist engine mounted hoses.
Reason : Resin inside of hoses may be bent or scratched,
and it may lower the permeation-proof function.
1-6 GENERAL PRECAUTIONS IN ASSEMBLY
(1) Be careful to keep parts, service tools, mating parts of various service equipment (including O-rings) free from
unspecified oil or dust.
(2) Avoid using refrigerant oil (such as ND-8 or ND-9) near painted surfaces and resin materials (acrylic resin, ABS
plastic, or polycarbonate).
(3) Remove a receiver shipping cap only just before mounting (connecting pipes). Also mount a receiver last of all the A/
C system parts, or at least assemble system parts while the receiver shipping cap is removed for only a short time (for
1 hour or less).
(2) Nut union-type
(a) Always assemble pipes using 2 wrenches.
(b) Pipes will rotate from 15° to 20° clockwise during
tightening, so anticipate the displacement caused by
rotation of the nut and then mount pipes.
(c) When finally tightening pipes, do not rotate the fixed side
(the female side).
(g) Remove a shipping cap just before connecting pipes.
Reason : To keep O-rings or O-ring seals from dust.
(h) During air conditioning installation, confirm there is no
interference between the pipes and vehicle parts. (Keep
proper clearances.)

(1) Automatic charging machine
Before evacuating air or charging refrigerant using the automatic charging machine, read the relevant manuals
thoroughly.
(2) Charging cylinder
When charging refrigerant using a charging cylinder, evacuate air then charge refrigerant as described below.
Charge gaseous refrigerant from Hi
pressure side until the Low pressure
gauge indicates 0.098Mpa (1kgf/cm2).
START EVACUATION
STOP EVACUATION
Leave the system with this
conditioning for 5 minutes.

4-2 FINAL LEAKAGE CHECK
This description is provided here as a reference for the checking procedure. When the air conditioner is installed it is
important to fill the specified amount of refrigerant. When checking the refrigerant amount during repairs, for example,
consult the vehicle repair manual.
(1) Check refrigerant amount through the sight glass.
(a) Set the following conditions
Engine speed...Idling
In case of dual type A/C...Switch both front and rear ON.
(b) Visually check a sight glass under the following
conditions.
Appropriate...Almost no bubbles
(Idling speed : After gradually increasing
speed, bubbles disappear at 1500 rpm.)
Excessive...No bubbles
(Pressures on both the high and low side
are high.)
Insufficient...Continuous bubble occurrence
NOTE
1. Pressure on the high pressure side when charging refrigerant should be 19 kg/cm (1.87 Mpa) or less. When
outside air temperature is high (40 °C or more) and if the pressure becomes more than 19 kg/cm (1.87 Mpa),
perform the check in a cool place with all the doors open and with the blower speed set to LO.
2. When an electric fan starts with an appropriate refrigerant level, bubbles might appear temporarily. (For about 5
seconds)
(2) In case of a 'low charge' above, there may be a leak. Then, check joint areas of each part with a leak tester , and repair
the leak.

Refer to the vehicle's manual for correct belt tension. Keep in mind that initially after five minutes of A/C operation, the belt
is likely to elongate.
Retension the belt if necessary after A/C operation and check.
4-5 RESTORE THE VEHICLE
Reinstall all the parts of vehicle that have between temporarily removed.
!CAUTION
1. In particular, improper installation of instrument panels parts, improper tightening of tapping screws or loose
connectors may cause abnormal noise. Therefore make sure that they are installed or fastened properly to avoid
abnormal noise that can occur after the air conditioning installation is complete.
Tightening torque for tapping screw ....................... 1.5 N·m (15 kgf·cm)
Tightening torque for cross recessed head bolt ..... 3.4 ± 1.4 N·m (35 ± 15 kgf·cm)
2. If the hole for a tapping screws is too large, use a tapping screw one-size larger.
3. Reinstall each part with particular care so that its clips, guides bosses fit in the specified positions.
4. When installing the instrument panel, make sure that wire harness is not pulled, pushed excessively or trapped.
4-4 ADJUSTMENT OF ENGINE IDLING SPEED
