After cutting, remove the pipe from the welded part of to the compressor -D- by using a burner.
N O T E
•
All the piping is connected to the compressor by welding. When applying the burner to the pipe connections,
the oil adhered inside the pipe may be burn. When welding, clean the compressor of flammable materials.
•
Burner work with gas pressure is very hazardous. Make sure that the pipes are cut before burner work.
11
Disconnect the oil discharge pipe -A- from the compressor.
When disconnecting pinch and cut the pipe in the area closest to
the compressor -D- so that the remaining compressor oil does not
overspill from the oil discharge pipe -A-.
Before disconnecting the oil discharge pipe at the piping side,
check that the oil at the welding part is completely removed.
Remove the oil discharge pipe from the welded part -C- by using a
burner.
N O T E
•
Remove the oil from the compressor into an oil pan -B-.
•
If the oil discharge pipe is disconnected without having
carried out the procedure (for example “Applying burner directly to the welding part), the refrigerant oil spilt
may be flammable. Make sure that you comply with the safety measures necessary to carry out the procedure.
•
Do not throw out the collected oil by the oil pan -B-. This quantity of oil must be measured.
12
: Remove the three compressor nuts -A- and remove the
compressor -B-.
N O T E
•
When removing the compressor take care not to touch the
surrounding pipes as it may become deformed.
•
Pay attention not to be injured with the sheet metal edge
while working.
•
When removing the compressor, seal the end of the oil discharge pipe -C- to avoid losing oil.
•
D: Discharge pipe.
•
E: Suction pipe.
•
Do not expose the refrigerant cycle to the atmosphere for a long period of time to avoid mixing water with
external particles.
•
Fit the new compressor as quickly as possible.
•
In the case of RAS-18FSXN:
– In the feet of the constant speed compressor -I- there are
special washers -F- (painted in silver) fixed to absorb
vibrations -C- together with the vibration proof rubber -H-.
Never remove these washers. They are fixed with special
nuts -G-.
– Without these special nuts, the pipe may break with the
vibration of the compressor.
