l Seal any open space around the mains power wire and conduit at the mains input plate of the
compressor to prevent ingress of outside air and contaminants that could come from the mains power
cabinet.

NOTE
l Contact Danfoss LLC Applications for lower ambient temperature operations. Refer to Figure Operating Envelopes. in this
manual for details of the operating conditions. These conditions are in line with the AHRI 540 Standard.
l All compressors/components should be protected from environments that could cause corrosion to exposed metals. For
outdoor installations, a weather-proof enclosure with vents is recommended to house the compressor.
l TTS/TGS/TTH/TGH compressors can operate below -1°C ambient if refrigerant circuit is maintained at a minimum of -1°C
Saturated temperature.

The compressor, motor, and power assemblies are packaged in the design.
• • • CAUTION • • •
It is important to take all precautions to avoid refrigerant migration, especially on air-cooled units. If the compressor is filled with liquid,
there is a high risk of bearing damage, thus putting the compressor out of service. The compressor warranty will be voided if the
compressor is damaged due to refrigerant migration.
