Environment and Application Boundaries

The compressor and drive module are designed for indoor applications only and should be stored
and operated within the following conditions:
Condition Type
Enclosures and Cover Type
Storing/Shipping temperature
Operation
Temperature
Relative Humidity
Maximum wet bulb temperature
Altitude
Maximum Altitude Above Sea Level without De-rating
Maximum Operating Temperature at:
2000 m (6000 ft.)
3000 m (9000 ft.)
The Drive Module should not be installed in environments with airborne liquids, particles, or gases capable of
affecting and damaging the electronic components.
Failure to take the necessary protective measures increases the risk of stoppages, thus reducing the life of the
drive module.
The maximum design high-side pressure for the compressor is shown in Table 10.
Certification
-NC (UL/ETL)
The maximum pressure that the compressor
can operate is regulated directly by two control
settings: Warning Limit and Fault Limit.
Type
Maximum Pressure Warning Limits
Maximum Pressure Fault Limits
VTT series compressors are designed to operate
within an acceptable rated voltage and frequency.
The tables below specify the acceptable supply
voltage and frequency ranges. Using a supply
