COMPRESSORS
The compressor used in this product is specifically designed to operate
with R-410A Refrigerant and cannot be interchanged.
The compressor uses polyolester (POE oil), Mobile 3MA POE. This oil
is extremely hygroscopic, meaning it absorbs water readily. POE oil can
absorb 15 times as much water as other oils designed for HCFC and
CFC refrigerants. If refrigerant circuit is opened, take all necessary pre-
cautions to avoid exposure of the oil to the atmosphere.
POE (polyolester) compressor lubricants are known to cause long term
damage to some synthetic roofing materials.
Procedures which risk oil leakage include, but are not limited to, com-
pressor replacement, repairing refrigerant leaks, replacing refrigerant
components such as filter drier, pressure switch, metering device or
coil.
Units are shipped with compressor mountings which are factory-
adjusted and ready for operation.
SECTION V: AIRFLOW PERFORMANCE
1. Airflow tested with dry coil conditions, without air filters, at 230 volts.
2. Applications above 0.8" w.c. external static pressure are not recommended.
3. Brushless DC high efficiency standard ECM blower motor used for all indoor blower assemblies.
4. Minimal variations in airflow performance data results from operating at 208 volts. Data above may be used in those cases.
5. Heating applications tested at 0.50" w.c. esp, and cooling applications tested at 0.30" w.c.esp per standards.
CAUTION
This system uses R-410A Refrigerant which operates at higher pres-
sures than R-22. No other refrigerant may be used in this system.
CAUTION
Do not leave the system open to the atmosphere. Unit damage could
occur due to moisture being absorbed by the POE oil in the system.
This type of oil is highly susceptible to moisture absorption
!
!
CAUTION
Exposure, even if immediately cleaned up, may cause embrittlement
(leading to cracking) to occur in one year or more. When performing
any service that may risk exposure of compressor oil to the roof, take
precautions to protect roofing.
CAUTION
Do not loosen compressor mounting bolts.
