CAUTION
Damage to a replacement compressor
caused by improper system cleaning
constitutes abuse under the terms of the
warranty. This will
VOID THE COMPRESSOR
WARRANTY.
Always consult the factory prior
to replacing the compressor.
CAUTION
POE oil is used in systems with R-410A
refrigerant. If a replacement compressor is
provided, ensure that it is filled with POE oil
before installing.
4.3.4.2 Standard Cleanout Procedure
NOTE
Cleaning operations must be performed by a
journeyman, refrigeration mechanic, or air
conditioning technician.
1. Turn off power to the unit at the main power dis-
connect switch.
2. Remove the old compressor and install the
new compressor.
3. Remove the liquid line drier and install an
oversized liquid line filter-drier (one size larger
than the nor- mal selection size).
4. Evacuate the system according to standard
procedures. Normally, this will include the use of
a high- vacuum pump and a low-vacuum micron
gauge for measuring the vacuum obtained.
5. Recharge the system.
6. Turn on the power at the main power
disconnect switch and start the system at the
controller.
4.3.4.3 Burn-Out/Acidic Cleanup Procedure
CAUTION
Avoid touching or allowing the gas and oil
from contacting bare skin. Severe burns will
result. Use long rubber gloves to handle
contaminated parts.
NOTE
Cleaning operations must be performed by a
journeyman, refrigeration mechanic, or air
conditioning technician.
1. These systems should be cleaned using the
suction line filter-drier method.
2. Turn off power to the unit at the main power dis-
connect switch.
3. Remove the burned out compressor and install
the new compressor.
4. Install a suction line filter-drier designed for
acid removal.
5. Remove the liquid line drier and install an
oversized liquid line filter-drier (one size larger
than the nor- mal selection size).
6. Check the expansion valve, sight glass and
other controls to see if cleaning or
replacement is re- quired.
7. Evacuate the system according to standard
procedures. Normally, this will include the use of
a high- vacuum pump and a low-vacuum micron
gauge for measuring the vacuum obtained.
8. Recharge the system through the access
valve on the suction line filter-drier.
9. Turn on power at the main power
disconnect switch and start the system at
the controller.
10. The permanently installed suction line filter-drier
permits small-system cleanup to be completed
in one service call. The pressure drop across
the suction line filter-drier should be measured
during the first hour of operation. If the pressure
drop be- comes excessive, the suction line filter-
drier should be replaced (See Sporlan Bulletin
40-10, for the maximum recommended
pressure drop (PSI) for the suction line filter
drier).
11. In 24 hours, take an oil sample. Observe the
color and test for acidity. If the oil is dirty or
acidic, re- place the suction line filter-drier.
12. In 2 weeks, examine oil to determine if
another suction line filter-drier change is
necessary.
4.3.4.4 Humidifier Cylinder Replacement
After an extended period of operation, the yellow
LED on the humidifier cabinet will repeatedly flash
four times indicating that the cylinder is completely
used and a replacement cylinder must be installed.
The cylinder is disposable and cylinder life is
dependent on water supply conditions and
humidifier usage. Refer to the humidifier operator’s
manual supplied under separate cover for detailed
instructions on changing the cylinder. The following
procedures are to be followed when replacing the
cylinder.
CAUTION
Failure to replace the cylinder at the end of cylin-
der life may result in humidifier damage.
