SAFETY CONSIDERATIONS

Improper installation, adjustment, alteration, service maintenance,
or use can cause explosion, fire, electrical shock, or other

conditions which may cause death, personal injury, or property
damage. Consult a qualified installer, service agency, or your

distributor or branch for information or assistance. The qualified

installer or agency must use factory--authorized kits or accessories
when modifying this product. Refer to the individual instructions

packaged with the kits or accessories when installing.
Follow all safety codes. Wear safety glasses, protective clothing,

and work gloves. Have a fire extinguisher available. Read these
instructions thoroughly and follow all warnings or cautions

included in literature and attached to the unit. consult local

building codes, the current editions of the National Fuel Gas Code
(NFGC) NFPA 54/ANSI Z223.1, and the National Electrical Code

(NEC) NFPA 70.
In Canada refer to the current editions of the National Standards of

Canada CAN/CSA--B149.1 and .2 Natural Gas and Propane
Installation codes, and Canadian Electrical Code CSA C22.1
Recognize safety information. This is the safety--alert symbol

.

When you see this symbol on the unit and in instructions or manu-
als, be alert to the potential for personal injury. Understand these

signal words: DANGER, WARNING, and CAUTION. 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 hazards which

could

result in per-

sonal injury or death. CAUTION is used to identify unsafe practic-

es which

may

result in minor personal injury or product and prop-

erty damage. NOTE is used to highlight suggestions which

will

result in enhanced installation, reliability, or operation.

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal

injury or death.
Before installing or servicing system, always turn off main

power to system and install lockout tag. There may be

more than one disconnect switch. Turn off accessory heater

power switch if applicable.

!

WARNING

UNIT OPERATION AND SAFETY HAZARD

Failure to follow this warning could result in personal

injury or equipment damage.
Puron (R--410A) systems operate at higher pressures than

standard R--22 systems. DO NOT use R--22 service

equipment or components on Puron (R--410A) equipment.

Ensure service equipment is rated for Puron (R--410A).

WARNING

!

CUT HAZARD

Failure to follow this caution may result in personal injury.
When removing access panels or performing maintenance

functions inside your unit, be aware of sharp sheet metal

parts and screws. Although special care is taken to reduce

sharp edges to a minimum, be extremely careful when

handling parts or reaching into the unit.

CAUTION

!

INTRODUCTION

The 577D----A packaged unit is a fully self--contained combination
Category I gas heating/electric air conditioner designed for outdoor

installation (See Fig. 1). Standard units are shipped in a

horizontal--discharge configuration for installation on a rooftop, or
on cement slab (See Fig. 4 for roof curb dimensions). Standard

units can be converted to downflow (vertical) discharge
configurations for rooftop applications.
Models with an N in the thirteenth position of the model number

are dedicated Low NOx units designed for California installations.

These models meet the California maximum oxides of nitrogen
(NOx) emissions requirements of 40 nanograms/joule or less as

shipped from the factory and must be installed in California Air
Quality Management Districts or any other regions in North

America where a Low NOx rule exists.

In gas heating mode, this unit is designed for a minimum
continuous return--air temperature of 55

_

F (13

_

C) db and a

maximum continuous return--air temperature of 80

_

F (27

_

C) db.

Failure to follow these return--air temperature limits may affect

reliability of heat exchangers, motors, and other components.

NOTE

:

Low NOx requirements apply only to natural gas

installations.

RECEIVING AND INSTALLATION

Check Equipment

IDENTIFY UNIT

The unit model number and serial number are printed on the unit
informative plate. Check this information against shipping papers.

INSPECT SHIPMENT
Inspect for shipping damage before removing packaging material.

If unit appears to be damaged or is torn loose from its anchorage,

have it examined by transportation inspectors before removal.
Forward claim papers directly to transportation company.

Manufacturer is not responsible for any damage incurred in transit.
Check all items against shipping list. Immediately notify the

nearest distributor office if any item is missing. To prevent loss or

damage, leave all parts in original packages until installation.
If the unit is to be mounted on a curb in a downflow application,
review “Configuring Units for Downflow Discharge” to determine

which method is to be used to remove the downflow panels before
rigging and lifting into place. The panel removal process may

require the unit to be on the ground.

Provide Unit Support

IMPORTANT

: The unit must be secured to the curb by installing

screws through the bottom of the curb flange and into the unit base
rails. When installing large base units onto the common curb, the
screws must be installed before allowing the full weight of the unit
to rest on the curb. A minimum of six screws are required for large
base units. Failure to secure unit properly could result in an
unstable unit. See Warning near Rigging/Lifting information and
accessory curb instructions for more details.
For hurricane tie downs, contact distributor for details and PE
(Professional Engineering) Certificate, if required.

ROOF CURB

Install accessory roof curb in accordance with instructions shipped
with curb (See Fig. 4). Install insulation, cant strips, roofing, and

flashing. Ductwork must be attached to curb.

IMPORTANT

: The gasketing of the unit to the roof curb is

critical for a water tight seal. Install gasketing material supplied
with the roof curb. Improperly applied gasketing also can result in
air leaks and poor unit performance.
Curb should be level to within 1/4 in. (6.35 m) (See Fig. 2). This is
necessary for unit drain to function properly. Refer to accessory

roof curb installation instructions for additional information as
required.
