SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment can be

hazardous due to system pressure and electrical components. Only

trained and qualified service personnel should install, repair, or

service air-conditioning equipment.

Untrained personnel can perform basic maintenance functions of

cleaning coils and filters and replacing filters. All other operations

should be performed by trained service personnel. When working

on air-conditioning equipment, observe precautions in the litera-

ture, tags and labels attached to the unit, and other safety precau-

tions that may apply.

Follow all safety codes, including ANSI (American National Stan-

dards Institute) Z223.1. Wear safety glasses and work gloves. Use

quenching cloth for unbrazing operations. Have fire extinguisher

available for all brazing operations.

WARNING

Before performing service or maintenance operations on unit,

turn off main power switch to unit. Electrical shock could

cause personal injury.

WARNING

Improper installation, adjustment, alteration, service, or main-

tenance can cause injury or property damage. Refer to this

manual. For assistance or additional information, consult a

qualified installer, service agency, or the gas supplier.

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 gage for how

much oil to add to the system.

e.Carefully unsweat remaining tubing stubs when neces-

sary. 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 com-

pleted. Failure to follow these procedures may result in dam-

age to equipment.
