WARNING

Compressor weighs as much as 92 lbs. (41.72 kg) and could cause injury to

personnel and damage to equipment if not handled properly while removing from

unit. Two personnel are required to lift the compressor.

CAUTION

When an overhead lifting device is used to remove the condenser fan supports (WP

0064-00), use an appropriate sling so that the weight of the unit is supported by the

base of the shipping container.

WARNING

Do not allow the unit to swing while suspended from a lifting device. Failure to

observe this warning may result in injury to personnel and damage to the equipment.

WARNING

Disconnect air conditioner power supply.

WARNING

Purge system with dry nitrogen prior to soldering or de-soldering; refrigerant heated

by flame or hot surfaces creates phosgene gas, a highly toxic gas.

WARNING

Do not let refrigerant touch you or inhale refrigerant gas. Be especially careful to

prevent refrigerant from coming in contact with your eyes. Use a air filtering mask.

In case of refrigerant leaks, ventilate area at once.

WARNING

Follow general debrazing instructions given in WP 0051-00. Provide a flow of dry

nitrogen through the refrigeration system while debrazing connections.
