Recovery unit
2. Do not release refrigerant into the air
Although HFC-134a is not subject to CFC regulations,
it can have effect on global warming and so should
not be released into the air. When removing
refrigerant from the air conditioning system, always
use a refrigerant recovery unit made specifically
for HFC-134a.
Compressor handling
Do not strike or unecessarily turn the compressor
upside down. If the compressor is knocked over or
turned upside down during handling or installation,
rotate the armature plate 5 or 6 times to circulate
the oil.
Otherwise, oil in the cylinder during compressor
start-up will cause valve damage and reduce
durability.
Compressor removal
When the compressor is operational
1. Perform the oil return operation (see p.16).
2. Recover the refrigerant from the system using
a refrigerant recovery unit.
3. Remove the compressor.
4. Drain the oil from the compressor and close all
open connections immediately.
5. Check the oil quantity and the degree of
contamination (see p.17).
When the compressor is inoperable
1. Recover the refrigerant from the system using
a refrigerant recovery unit if the shut-off valves
are to be removed with the compressor.
2. Remove the compressor.
3. Drain the oil from the compressor and close all
open connections immediately.
4. Check the oil quantity and the degree of
contamination (see p.17).
