CAUTION
DO NOT re-use compressor oil or any oil that has been ex-
posed to the atmosphere. Dispose of oil per local codes and
regulations. DO NOT leave refrigerant system open to air
any longer than the actual time required to service the
equipment. Seal circuits being serviced and charge with dry
nitrogen to prevent oil contamination when timely repairs
cannot be completed. Failure to follow these procedures
may result in damage to equipment.

Step 1 — Complete Pre-Installation Checks
Examine unit for damage incurred during shipment. File claim im-
mediately with transit company if damage is found. Check the
shipment for completeness. Verify that the nameplate electrical re-
quirements match the available power supply.
DO NOT place the unit in a horizontal position that would allow
oil to drain into the top of the compressor. Do not allow refrigerant
lines to come into contact with wiring or sharp objects or edges.
