gas valve, if applicable, and the temperature limit

switch on gas heat units. The unit control board will

alarm on ignition failures, compressor lockouts and

repeated limit switch trips.

FEATURES

All models are available with a wide variety of factory-

mounted options such as stainless steel heat exchangers,

electric heaters, phase monitor, convenience outlet, dirty filter

switch, disconnect switch, smoke detectors, and coil guard to

make them suitable for almost every application.

•

Nuisance Trip Protection- To prevent nuisance

trouble calls, the control board uses a “three strikes,

you’re out” philosophy. The high and low-pressure

switches and the freezestats must trip three times

within two hours before the unit control board will

lock out the compressor.

All units are self-contained and assembled on full perimeter

base rails with forklift holes on three sides and holes for over-

head rigging. Every unit is completely piped, wired, charged

and tested at the factory to simplify the field installation and to

provide years of dependable operation.

On Board Diagnostics - Each alarm will energize a

trouble light on the thermostat, if so equipped, and

flash an alarm code on the control board LED. Each

high and low-pressure switch alarm as well as each

freezestat alarm has its own flash code. The control

board saves the five most recent alarms in memory,

and these alarms can be reviewed at any time.

Alarms and programmed values are retained

through the loss of power.

All models (including those with an economizer) are suitable for

either bottom or horizontal duct connections. For bottom duct,

remove the sheet metal panels from the supply and return air

openings through the base of the unit. For horizontal duct,

remove the supply and return air panels on the rear of the unit.

All models are available with these “factory mounted” outdoor

air damper options:

All units have long lasting powder paint cabinets with 1000

hour salt spray test approval under ASTM-B117 procedures.

•

Single enthalpy economizer

Motorized outdoor air damper

All models are CSA listed.

•

Warranty - All models include a one-year limited parts

warranty on the complete unit. Compressors and electric

heater elements carry a five-year warranty. Gas heat

exchangers carry a 10-year parts warranty.

Supply air blowers are equipped with either direct drive or

belt drive that can be adjusted to meet the exact require-

ments of the job.

All compressors are equipped with internal pressure relief.

Every refrigerant circuit includes a liquid line filter-drier, a high

pressure switch and a suction line with a freezestat and low

pressure/loss of charge switch to protect all system compo-

nents.

•

Gas Heat Operation - All single phase models with gas

heat have minimum annual fuel utilization efficiency

(AFUE) of 80%. All three phase models with gas heat

have minimum steady state efficiency of 80%. Each sec-

tion includes a durable heat exchanger with aluminized

steel or optional stainless steel tubes, a redundant gas

valve, spark ignition, power venting, an ignition module

for 100% shut-off and all of the safety controls required

to meet the latest ANSI standards.

•

S implicity Controls - S implicity control boards have

standardized a number of features previously available

only as options or by utilizing additional controls.

•

Low Ambient - An integrated low-ambient control

allows all units to operate in the cooling mode down

to 0ºF outdoor ambient without additional assis-

tance. Optionally, the control board can be pro-

grammed to lockout the compressors when the

outdoor air temperature is low or when free cooling

is available.

The gas supply piping can be routed into the heating

compartment through a hole in the base pan of the unit

or through a knockout in the piping panel on the front of

the unit.

•

Electric Heat Operation - All electric heat models are

wired for a single power source and include a bank of

nickel chromium elements mounted at the discharge of

the supply air blower to provide a high velocity and uni-

form distribution of air across the heating elements.

Every element is fully protected against excessive tem-

perature by thermal limit switches.

•

Anti-Short Cycle Protection - To aid compressor

life, an anti-short cycle delay is incorporated into the

standard controls. Compressor reliability is further

ensured by programmable minimum run times. For

testing, the anti short cycle delay can be temporarily

overridden with the push of a button.

The power supply wiring can be routed into the control

box through a threaded pipe connection (field supplied)

in the base pan of the unit or through a knockout in the

wiring panel on the side of the unit.

•

Fan Delays - Fan on and fan off delays are fully pro-

grammable and are independent of one another. All

units are programmed with default values based

upon their configuration of cooling and heat.

Safety Monitoring - The control board monitors the

high and low-pressure switches, the freezestats, the

1. Deduct these resistance values from the available external static pressure shown in SUPPLY AIR BLOWER PERFORMANCE Tables.

2. Add these resistance values to the available static resistance values on SUPPLY AIR BLOWER PERFORMANCE Tables.

3. The pressure through the economizer is greater for 100% outdoor air than for 100% return air. If the resistance of the return air

duct system is less than 0.25 IWG, the unit will deliver less CFM during full economizer operation.

level or set on steel beams above a finished roof. Cooling

only, cooling with gas heat and cooling with electric heat

models are available with a wide variety of factory-mounted

options and field-installed accessories to make them suitable

for almost every application. All units are self-contained and

assembled on full perimeter base rails with holes in the four

corners for overhead rigging. Every unit is completely piped,

wired, charged and tested at the factory to simplify the field

installation and to provide years of dependable operation. All

models (including those with an economizer) are suitable for

either bottom or horizontal duct connections. Models with

power exhaust are suitable for bottom duct connections only.

For bottom duct, remove the sheet metal panels from the

supply and return air openings through the base of the unit.

For horizontal duct, remove the supply and return air panels

on the rear of the unit.
