Steps Image Instructions
4. Loosen screws
at the feet of the
compressor.
• Loosen screws at feet of the
compressor with a adjustable or
bushing spanner.
• Loosened screws should be put
together to avoid loss.
5. Replace the
compressor with a
new one.
• During replacement, care must be
taken to not damage rubber pads.
• Seal the replaced compressor to
prevent moisture entering;
• Place a new compressor at the
rubber pads. Steel bushing is
required for rubber pads.
• Tighten the steel bushing with
screws.
6. Reconnect the
suction line, the
discharge line, other
pipes and electric
lines. Then, check
for normal operation
of the compressor.
• Reconnect and resolder the suction
and discharge lines. Charge nitrogen
during soldering.
• After soldering, charge high-pres
sure nitrogen for the leak test.
• Power on the unit and start it through
an AC contact for 2 to 3 seconds.
• When the compressor runs reversely,
it would generate harsh noise.
