NOTE TO INSTALLER — Before the installation, READ
THESE INSTRUCTIONS CAREFULLYAND COMPLETELY.
Also, make sure the User’s Manual and Replacement Guide
are left with the unit after installation. This unit is NOT to
be used for temporary heating of buildings or structures un-
der construction.
SAFETY CONSIDERATIONS
Installation and servicing of air-conditioning equipment can
be hazardous due to system pressure and electrical compo-
nents. Only trained and qualified personnel should install,
repair, or service air-conditioning equipment.
Untrained personnel can perform basic maintenance func-
tions of cleaning coils and filters. All other operations should
be performed by trained service personnel. When working on
air-conditioning equipment, observe precautions in the lit-
erature, 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 ex-
tinguisher available for all brazing operations.
WARNING:
Improper installation, adjustment, alter-
ation, service, maintenance,oruse can cause carbon mon-
oxide poisoning, fire, or an explosion which can result
in personal injury or unit damage. Consult a qualified
installer, service agency, or gas supplier for informa-
tion or assistance. The qualified installer or agency must
use only factory-authorized kits or accessories when modi-
fying this product.
WARNING:
Before performing service or mainte-
nance operations on unit, turn off gas supply then unit
main power switch. Electrical shock could cause per-
sonal injury.
GENERAL
The 588A, 589Aunits (see Fig. 1) are fully self-contained, com-
bination Category I gas heating/electric cooling units de-
signed for outdoor installation. See Fig. 2-9 (pages 2-9) for
unit dimensions. All unit sizes have discharge openings for
both horizontal and downflow configurations, and are factory
shipped with all 4 duct openings covered. Units may be in-
stalled either on a rooftop or a ground-level cement slab. See
Fig. 10 for roof curb dimensions.

Field Fabricate Ductwork

Secure field-fabricated ductwork to building structure and unit flanges.

Provide Clearances

Ensure required operating and service clearances for combustion and ventilation.

Rig and Place Unit

Use proper rigging and lifting techniques to place the unit level.

PRE-START-UP

Safety Warnings and Inspections

Observe safety warnings and perform inspections for shipping damage, leaks, and connections.

START-UP

Check for Refrigerant Leaks

Locate and repair refrigerant leaks, then charge the unit.

Start Up Heating Section and Make Adjustments

Check heating control operation, burner ignition, and gas input.

Start Up Cooling Section and Make Adjustments

Check cooling control operation, compressor, and fan startup.

MAINTENANCE

Air Filter

Inspect and clean/replace air filters monthly for optimal performance.

Unit Top Removal

Procedures for safely removing and reinstalling the unit top.

Evaporator Blower and Motor

Clean and lubricate blower motor and wheel annually.

Flue Gas Passageways

Inspect and clean flue collector box and heat exchanger areas.

Combustion-Air Blower

Clean blower wheel periodically for proper airflow and heating efficiency.

Limit Switch

Locate limit switch on gas partition for service.

Burner Ignition
