1. Before powering the unit, heed the precautions given above for the test operation.

WARNING

Hazardous Voltage, Rotating Components!

Do not operate the product with the panel or duct outlet protection net off. There is risk of

personal injury from parts that rotate or contain high voltage.

CAUTION

Risk of Burn or Frostbit!

Refrigerant pipe may be hot or cold during or right after the operation depending on the status

of the refrigerant which flows through the refrigerant pipe, compressor, and other parts of the

refrigerant cycle. Do not touch the refrigerant pipe during or right after the operation to avoid
