CAUTIONS
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.
POE oil is used in systems with R407C 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 unit at the main power disconnect
switch.
2.
Remove the old compressor and install the new com-
pressor.
3.
Remove the liquid line drier and install an oversized
liquid line filter-drier (one size larger than the normal
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.
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 disconnect
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 normal
selection size).
6.
Check the expansion valve, sight glass and other controls
to see if cleaning or replacement is required.
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.
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 becomes 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, replace the suc-
tion 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 cylinder
life may result in humidifier damage.
NOTE
Decrease the humidity set point below ambient
humidity to allow the cylinder to cool down before
removing the cylinder.
1.
Turn the A/C unit off by pressing and holding the Enter
key.
