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.
