warranty. Always consult the factory prior
to replacing the compressor.
Standard Cleanout Procedure
WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Verify that no power is present
with a voltmeter.
WARNING
Severe Burns!
Avoid touching or contacting refrigerant gas and oil
with exposed skin. Severe burns will result. Use long
rubber gloves when handling contaminated parts.
Note: Cleaning operations must be performed by a
journeyman refrigeration mechanic or air
conditioning technician.
1. If your unit is equipped with an E² controller, turn the
A/C unit off by pressing and holding the Enter key.
2. Turn off power to the unit at the main power disconnect
switch.
3. Remove the old compressor and install the new
compressor.
4. Remove the liquid line drier and install the appropriate
liquid line filter-drier.
5. 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.
6. Recharge the system.
7. Turn on the power at the main power disconnect switch
and start the system.
Burn-Out/Acidic Cleanup Procedure
WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Verify that no power is present
with a voltmeter.
AH-SVX008C-EN
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. If your unit is equipped with an E² controller, turn the
A/C unit off by pressing and holding the Enter key.
3. Turn off power to the unit at the main power disconnect
switch.
4. Remove the burned-out compressor and install the
new compressor.
5. Install a suction line filter-drier designed for acid
removal.
6. Remove the liquid line drier and install the appropriate
liquid line filter-drier.
7. Check the expansion valve, sight glass and other
controls to see if cleaning or replacement is required.
8. 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.
9. Recharge the system through the access valve on the
suction line filter-drier.
10. Turn on power at the main power disconnect switch
and start the system.
11. The 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 becomes excessive, the suction line
filter-drier should be replaced (See Sporlan Bulletin 40-
10, for the maximum recommended pressure drop for
the suction line filter drier).
12. In 24 hours, take an oil sample. Observe the color and
test for acidity. If the oil is dirty or acidic, replace the
suction line filter-drier.
13. In two weeks, examine oil to determine if another
suction line filter-drier change is necessary.
Humidifier Cylinder Replacement
WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Verify that no power is present
with a voltmeter.
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
