FIGURE 5 - COMPRESSOR FLUSHING
a.
Mount the compressor in a vise over a drain pan using Compressor Holding Fixture J-9396 (A-6), J-33026 (DA-6), J-25008-A
(R-4) or J-34992 (V-5).
b.
Invert the compressor and drain the oil through the suction and discharge ports. Also drain A-6 and V-5 compressors through the
crankcase oil drain plug. See "REFRIGERANT OIL DISTRIBUTION" procedures as outlined in the appropriate Service
Information Manual.
c.
Set the compressor in the upright position (suction/discharge ports pointing upwards) and force liquid R-11 into the compressor
suction port (larger internal opening) until clean R-11 flows from the discharge port (smaller internal opening), see Figure 5. Use
the large orifice nozzle flush gun J-33883-50 or equivalent.
d.
Turn the compressor by rotating the clutch driver for 1 or 2 turns, if possible. DO NOT FORCE. R-11 will be pumped out of the
discharge port (smaller internal opening).
e.
Refill the compressor with R-11 (Figure 5) and cap the suction/ discharge ports with a compressor shipping cap. Rock or shake the
compressor. Wait a minimum of 5 minutes before removing the cap, inverting the compressor (suction/discharge ports pointing
towards the drain pan) and draining the compressor.
f.
Force R-12 vapor into the compressor suction port (larger internal opening) to purge the remaining R-11, see Figure 5. Use the
large orifice nozzle flush gun J-33883-50 or equivalent. Continue to blow R-12 vapor until no liquid is observed leaving the
discharge port (smaller internal opening).
5.
ADD 525 VISCOSITY REFRIGERANT OIL TO REFRIGERANT SYSTEM -
A.
Drain as much oil as possible from the new or rebuilt compressor (see "DISCHARGING, ADDING OIL,
EVACUATING AND CHARGING" procedures as outlined in the appropriate Service Information Manual). A residual
quantity of refrigerant oil will remain in the the compressor that cannot be drained. A flushed compressor has no residual
quantity of oil. The residual quantity of oil for a new or rebuilt compressor is as follows:
Total System Capacity
Residual Quantity
Add Quantity
A-6 -- 330 ml (11 fl.oz.)
=
30 ml (1 fl.oz.)
+
300 ml (10 fl.oz.)
DA-6 -- 240 ml (8 fl.oz.)
=
45 ml (1.5 fl.oz.)
+
195 ml (6.5 fl.oz.)
R-4 -- 180 ml (6 fl.oz.)
=
30 ml (1 fl.oz.)
+
150 ml (5 fl.oz.)
V-5 -- 240 ml (8 fl.oz.)
=
45 ml (1.5 fl.oz.)
+
195 ml (6.5 fl.oz.)
Total System Capacity is the proper refrigerant oil quantity for a new or totally flushed system. Add Quantity is the proper
refrigerant oil quantity for a new or totally flushed system with a new or rebuilt drained compressor. If the accumulator,
condenser, evaporator or any other air conditioning component is not flushed or replaced, the above table is not applicable.
See "REFRIGERANT OIL DISTRIBUTION" procedures as outlined in the appropriate Service Information Manual to
determine proper refrigerant oil quantity to be added.
B.
Add the proper amount of new 525 viscosity refrigerant oil back into the compressor so that the total system capacity is correct.
This will ensure the refrigerant system has the proper oil charge.
