SAFETY CONSIDERATIONS

Installing, starting up, and servicing air-conditioning components

and equipment can be dangerous. Only trained, qualified installers

equipment.

When working on the equipment, observe precautions in the liter-

ature and on tags, stickers, and labels attached to the equipment.

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 and service.

There may be more than one disconnect switch. Tag all

disconnect 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 goggles

and proceed as follows:

a.Shut off electrical power to unit.

b.Recover refrigerant to relieve all pressure from system

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. Refrigerant 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 gauge for how

much oil to add to the system.

e.Carefully un-sweat remaining tubing stubs when neces-

sary. Oil can ignite when exposed to torch flame.

Failure to follow these procedures may result in personal inju-

ry or death.
