CD Player and Air Conditioning System-13
1 .CC6460K air conditioning system is designed with SD7V16 compressor, whose refrigeration oil type as
specified is SP-10P AG; hence application of other type of refrigeration oil may damage the parts and compo
nents of the compressor. When the
air conditioning system goes through maintenance and replacement of
parts, it should be added with new refrigeration oil, whose volume is listed as follows: the evaporator and
condenser: 30ml; the drier: 20ml; the pipeline: 10ml.
Addition of refrigeration oil can be available with two methods: The direct addition and the vacuum suction
2 .D irect addition method
a. remove the oil filler plug and fill with the specified SP-10P AG refrigeration oil.
b. observe through the hole of oil filter plug and rotate front plate of clutch to make the piston connecting rod right positio n in the
center of the hole of oil filter plug.
c. insert the dipstick along the right side of piston connecting rod till the top of dipstick touches the case of the compresso
r
d. pull out the dipstick and examine the graduations (grooves) of refrigeration oil, the readings shall be within the range of 4-6
scales
.
e. screw firmly the oil filter plug with the fastening torque of 14.7± 4.9N
.m
3. Vacuum suction method:
Firstly pump out the refrigerating system to the vacuum of 0.2x105Pa, and then fill with the specified 0.2x10 5 Pa refrigeration oil;
the detailed steps are as follows:
a. switch off the high-pressure manual valve and the auxiliary valve.
b. dismantle the high-pressure side hose from the manifold pressure gauge and insert it into the oil cu
p
c. open the auxiliary valve and have the refrigeration oil sucked into the refrigerating system from the oil cup.
d. when the refrigeration oil in the oil cup is almost pumped out to the vacuum, then immediately turn off the auxiliary valve
to
prevent the air from being sucked into the system
.
e. secure the hose adapter at high-pressure side to the manifold pressure gauge, start the vacuum pump and turn on the high-
pressure manual valve, then turn on the auxiliary valve to pump the system to the vacuum state of 0.2x10
5Pa, keep such state
for 15mins so as to discharge out the air flowing into the system along with the oil.

Daily Maintenance of Air Conditioning System
In order to ensure normal operation of air conditioning system, maintenance and care services shall be frequently performed for the
air conditioning system. The daily maintenance of air conditioning system is illustrated as follows:
1. Inspect, wash and clean the condenser of air conditioning system, requiring that radiator pins are clean and there is no dirt
between the pins. After the car runs in the rain or on the muddy road, the fan of the condenser should be inspected to find
whether it bears the earth, sand, stone and etc, and remove them if any.
2. Check the quantity of the working media of the refrigerating system; when the compressor set works normally, observe the
liquid viewing glass, under the normal circumstance, there shall be not air bubbles in the glass.
3. Inspect the drive belt. The belt between the compressor and the engine should be tensioned.
4. Check if there is any abnormal noise or odor in the air conditioning system.
5. Check if the temperature difference between the air inlet and outlet of the compressor is normal.
6. Check if the hose of the refrigerating system is in an apparent good condition and connections of all joints are secure.
7. Check if the pipeline of the refrigerating system collides with other parts and components, and if there is any oil leakage trace
left at each joint.
8. Check if the circuit connection of the refrigerating system is secure and if there is an occurrence of short circuit and falling off
9. Check if fastening bolts of the compressor are firmly secured or broken. d. When connecting the pipe, apply little compressor oil to the O-ring and fasten the nut with two wrenches. Attention: never
spatter the compressor oil to the painted parts or the plastic components to avoid the corrosion. If these components are
spattered with the oil, please clean it immediately.
e. When connecting the pipe, please follow the torque listed in the following table to fasten the screws or the nuts:
Diameter of Pipe Fastening Torque (N·m)
￠8mm 12-15
￠16mm 30-35 30－35


At ends of each pipe the protective caps should be installed till the pipe is connected to the refrigerating system.
compressor oil fasten it by using two wrenches at the same time
