SAFETY CONSIDERATIONS

Installing, starting up, and servicing air-conditioning com-

ponents and equipment can be dangerous. Only trained, quali-

fied installers and service mechanics should install, start-up,

and service this equipment.

When working on the equipment, observe precautions in the

literature and on tags, stickers, and labels attached to the equip-

ment. Follow all safety codes. Wear safety glasses and work

gloves.

WARNING

Electrical shock can cause personal injury and death. Shut

off all power to this equipment during installation. There

may be more than one disconnect switch. Tag all discon-

nect locations to alert others not to restore power until work

is completed.

CAUTION

Use care in handling, rigging, and setting bulky equipment.

Personal injury could result.

WARNING

DO NOT USE TORCH to remove any component. System

contains oil and refrigerant under pressure.
To remove a component, wear protective gloves and gog-

gles and proceed as follows:
a. Shut off electrical power to unit.
b. Recover refrigerant to relieve all pressure from sys-

tem using both high-pressure and low pressure ports.

c. Traces of vapor should be displaced with nitrogen

and the work area should be well ventilated. Refrig-

erant in contact with an open flame produces toxic

gases.

d. Cut component connection tubing with tubing cutter

and remove component from unit. Use a pan to catch

any oil that may come out of the lines and as a gage

for how much oil to add to the system.

e. Carefully unsweat remaining tubing stubs when nec-

essary. Oil can ignite when exposed to torch flame.

Failure to follow these procedures may result in personal

injury or death.

CAUTION

DO NOT re-use compressor oil or any oil that has been

exposed 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 proce-

dures may result in damage to equipment.
