NOTE TO INSTALLER — Before the installation, READ THESE

INSTRUCTIONS CAREFULLY AND COMPLETELY. Also,

make sure the User’s Manual and Replacement Guide are left with

the unit after installation.

SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment can be

hazardous due to system pressure and electrical components. Only

trained and qualified workers should install, repair, or service

air-conditioning equipment.

Untrained workers can perform basic maintenance functions of

cleaning coils and filters. All other operations should be performed

by trained service people. When working on air-conditioning

equipment, pay attention to precautions in the literature, tags and

labels attached to the unit, and other safety precautions that may

apply.

Follow all safety codes. 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 system, turn off main power to unit. Turn

off accessory heater power switch if applicable. Electrical

shock can cause serious injury or death.

RULES FOR SAFE INSTALLATION AND OPERATION

Recognize safety information. This is the safety-alert symbol

When you see this symbol in instructions or manuals, be alert to

the potential for personal injury.

Understand the signal words DANGER, WARNING, CAUTION,

and NOTE. These words are used with the safety-alert symbol.

DANGER identifies the most serious hazards which will result in

severe personal injury or death. WARNING signifies a hazard

which could result in personal injury or death. CAUTION is used

to identify unsafe practices which would result in minor personal

injury or product and property damage. NOTE is used to highlight

suggestions which will result in enhanced installation, reliability,

or operation.

These instructions cover minimum requirements and conform to

existing national standards and safety codes. In some instances,

these instructions exceed certain local codes and ordinances,

especially those that may not have kept up with changing residen-

tial construction practices. We require these instructions as a

minimum for a safe installation.

A. General

564A cooling units are fully self-contained and designed for

outdoor installation. See Fig. 1. As shown in Fig. 2-4, units are

shipped in a horizontal-discharge configuration for installation on

a ground-level slab. All units can be field-converted to downflow

discharge configurations for rooftop applications with a field-

supplied plenum.
