DUCTWORK

Ductwork should be designed and sized according to the

methods in Manual D of the Air Conditioning Contractors of

America (ACCA) or as recommended by any other recog-

nized authority such as ASHRAE or SMACNA.

A closed return duct system should be used. This will not

preclude use of economizers or outdoor fresh air intake. The

supply and return air duct connections at the unit should be

made with flexible joints to minimize noise.

The supply and return air duct systems should be designed

for the CFM and static pressure requirements of the job. They

should NOT be sized to match the dimensions of the duct

connections on the unit.

Refer to Figure 9 for bottom air duct openings. Refer to Fig-

ure 10 for rear air duct openings.

DUCT COVERS

Units are shipped with the side duct openings covered and a

covering over the bottom of the unit. For bottom duct applica-

tion, no duct cover changes are necessary. For side duct

application, remove the side duct covers and install over the

bottom duct openings. The panels removed from the side

duct connections are designed to be reused by securing each

panel to its respective downflow opening. But keep in mind

that the supply panel is installed with the painted surface UP,

facing the heat exchanger, while the return panel is installed

with the painted surface DOWN, facing the downflow duct

opening. The supply panel is secured with the bracket

(already in place from the factory) and two screws. It’s a snug

fit for the panel when sliding it between the heat exchanger

and unit bottom, but there is room. The return panel is

secured with four screws.

Note orientation. Panel is “insulation” side up.

CONDENSATE DRAIN

The side condensate drain is reversible and maybe re-ori-

ented to the rear of the cabinet to facilitate condensate pip-

ing. A condensate drain connection is available through the

base pan for piping inside the roof curb. Trap the connection

per Figure 16. The trap and drain lines should be protected

from freezing.

Plumbing must conform to local codes. Use a sealing com-

pound on male pipe threads. Install condensate drain line

from the 3/4 inch NPT female connection on the unit to an

open drain.

COMPRESSORS

The compressors are mounted on elastomer insulators. The

mounting bolts have been fully tightened for shipping.

FILTERS

Two-inch filters are supplied with each unit. One-inch filters

may be used with no modification to the filter racks. Filters

must always be installed ahead of evaporator coil and must

be kept clean or replaced with same size and type. Dirty fil-

ters reduce the capacity of the unit and result in frosted coils

or safety shutdown. Refer to physical data tables, for the

number and size of filters needed for the unit. The unit should

not be operated without filters properly installed.

When fastening ductwork to side duct flanges on

unit, insert screws through duct flanges only. DO

NOT insert screws through casing. Outdoor duct-

work must be insulated and water-proofed.

THERMOSTAT WIRING

The thermostat should be located on an inside wall approxi-

mately 56 inch above the floor where it will not be subject to

drafts, sun exposure or heat from electrical fixtures or appli-

ances. Follow the manufacturer's instructions enclosed with

thermostat for general installation procedure. Seven (7) color-

coded, insulated wires should be used to connect the thermo-

stat to the unit. Refer to Table 8 for control wire sizing and

maximum length.

POWER AND CONTROL WIRING

Field wiring to the unit, fuses, and disconnects must conform

to provisions of National Electrical Code (NEC), ANSI/NFPA

No. 70 – Latest Edition (in U.S.A.), current Canadian Electri-

cal Code C221, and/or local ordinances. The unit must be

electrically grounded in accordance with NEC and CEC as

specified above and/or local codes.

Voltage tolerances which must be maintained at the com-

pressor terminals during starting and running conditions are

indicated on the unit Rating Plate and Table 1.

The internal wiring harnesses furnished with this unit are an

integral part of the design certified unit. Field alteration to

comply with electrical codes should not be required. If any of

the wire supplied with the unit must be replaced, replacement

wire must be of the type shown on the wiring diagram and the

same minimum gauge as the replaced wire.

A disconnect must be utilized for these units. Factory

installed disconnects are available. If installing a disconnect

(field supplied or York International® supplied accessory),

refer to Figure 4 for the recommended mounting location.

NOTE: Since not all local codes allow the mounting of a dis-

connect on the unit, please confirm compliance with

local code before mounting a disconnect on the unit.

Electrical line must be sized properly to carry the load. USE

COPPER CONDUCTORS ONLY. Each unit must be wired

with a separate branch circuit fed directly from the meter

panel and properly fused.

Refer to Figures 17, 18 and 19 for typical field wiring and to

the appropriate unit wiring diagram mounted inside control

doors for control circuit and power wiring information.

POWER WIRING DETAIL

Units are factory wired for the voltage shown on the unit

nameplate. Refer to Electrical Data Tables 9 to 28 to size

power wiring, fuses, and disconnect switch.

Power wiring is brought into the unit through the side of the

unit or the basepan inside the curb.

TABLE 8: CONTROL WIRE SIZES

Wire Size Maximum Length1

1. From the unit to the thermostat and back to the unit.

Avoid damage to internal components if drilling

holes for disconnect mounting.

When connecting electrical power and control wiring

to the unit, water-proof connectors must be used so

that water or moisture cannot be drawn into the unit

during normal operation. The above water-proofing

conditions will also apply when installing a field sup-

plied disconnect switch.

OPTIONAL ELECTRIC HEAT

The factory-installed heaters are wired for single point power

supply. Power supply need only be brought into the single

point terminal block.

These CSA approved heaters are located within the central

compartment of the unit with the heater elements extending

in to the supply air chamber.

Fuses are supplied, where required, by the factory. Some kW

sizes require fuses and others do not. refer to Table 31 for

minimum CFM limitations and to Tables 9 through 28 for elec-

trical data.

OPTIONAL GAS HEAT

These gas-fired heaters have aluminized-steel or optional

stainless steel, tubular heat exchangers with spark ignition.

GAS PIPING

Proper sizing of gas piping depends on the cubic feet per

hour of gas flow required, specific gravity of the gas and the

length of run. "National Fuel Gas Code" Z223.1 (in U.S.A.) or

the current Gas Installation Codes CSA-B149.1 (in Canada)

should be followed in all cases unless superseded by local

codes or gas utility requirements. Refer to the Pipe Sizing

Table 33. The heating value of the gas may differ with locality.

The value should be checked with the local gas utility.

NOTE: There may be a local gas utility requirement specify-

ing a minimum diameter for gas piping. All units

require a one-inch pipe connection at the entrance

fitting.

NOTE: Maximum capacity of pipe in cubic feet of gas per

hour based upon a pressure drop of 0.3 inch W.C.

and 0.6 specific gravity gas.

NOTE: There may be a local gas utility requirement specify-

ing a minimum diameter for gas piping. All units

require a 3/4 inch pipe connection at the entrance

fitting. Line should not be sized smaller than the

entrance fitting size.

GAS CONNECTION

The gas supply line can be routed within the space and roof

curb, exiting through the unit’s basepan. Refer to Figure 9 for

the gas piping inlet location. Typical supply piping arrange-

ments are shown in Figures 21 and 22. All pipe nipples, fit-

tings, and the gas cock are field supplied or may be

purchased in UPG accessory kit #1GP0405.

Gas piping recommendations:

1. A drip leg and a ground joint union must be installed in

the gas piping.

2. Where required by local codes, a manual shut-off valve

must be installed outside of the unit.

3. Use wrought iron or steel pipe for all gas lines. Pipe dope

should be applied sparingly to male threads only.

4. All piping should be cleaned of dirt and scale by ham-

mering on the outside of the pipe and blowing out loose

particles. Before initial start-up, be sure that all gas lines

external to the unit have been purged of air.

5. The gas supply should be a separate line and installed in

accordance with all safety codes as prescribed under

“Limitations”.

6. A 1/8-inch NPT plugged tapping, accessible for test gage

connection, must be installed immediately upstream of

the gas supply connection to the unit.

7. After the gas connections have been completed, open

the main shut-off valve admitting normal gas pressure to

the mains. Check all joints for leaks with soap solution or

other material suitable for the purpose. NEVER USE A

FLAME.

Natural gas may contain some propane. Propane is

an excellent solvent and will quickly dissolve white

lead and most standard commercial compounds. A

special pipe dope must be used when assembling

wrought iron or steel pipe. Shellac based com-

pounds such as Gaskolac or Stalastic, and com-

pounds such as Rectorseal #5, Clydes’s or John

Crane may be used.

FIRE OR EXPLOSION HAZARD

Failure to follow the safety warning exactly could

result in serious injury, death or property damage.

Never test for gas leaks with an open flame. use a

commercially available soap solution made specifi-

cally for the detection of leaks to check all connec-

tions. A fire or explosion may result causing property

damage, personal injury or loss of life.

The furnace and its individual shut-off valve must be

disconnected from the gas supply piping system

during any pressure testing at pressures in excess

of 1/2 PSIG.

Pressures greater than 1/2 PSIG will cause gas

valve damage resulting in a hazardous condition. If it

is subjected to a pressure greater than 1/2 PSIG, the

gas valve must be replaced.

The furnace must be isolated from the gas supply

piping system by closing its individual manual shut-

off valve during any pressure testing of the gas sup-

ply piping system at test pressures equal to or less

than 1/2 PSIG.

Threaded joints should be coated with a sealing

compound that is resistant to the action of liquefied

petroleum gases. Do not use Teflon tape.

LP UNITS, TANKS AND PIPING

All gas heat units are shipped from the factory equipped for

natural gas use only. The unit may be converted in the field

for use with LP gas with accessory kit model number

1NP0442.

All LP gas equipment must conform to the safety standards of

the National Fire Protection Association.

For satisfactory operation, LP gas pressure must be 10.5

inch W.C. at the unit under full load. Maintaining proper gas

pressure depends on three main factors:

1. The vaporization rate which depends on the temperature

of the liquid and the “wetted surface” area of the con-

tainer(s).

2. The proper pressure regulation. (Two-stage regulation is

recommended).

3. The pressure drop in the lines between regulators and

between the second stage regulator and the appliance.

Pipe size required will depend on the length of the pipe

run and the total load of all appliances.

Complete information regarding tank sizing for vaporization,

recommended regulator settings, and pipe sizing is available

from most regulator manufacturers and LP gas suppliers.

LP gas is an excellent solvent and will quickly dissolve white

lead and most standard commercial compounds. A special

pipe dope must be used when assembling wrought iron or

steel pipe for LP. Shellac base compounds such as Gaskolac

or Stalastic, and compounds such as Rectorseal #5, Clyde’s,

or John Crane may be used.

Check all connections for leaks when piping is completed

using a soap solution. NEVER USE A FLAME.

VENT AND COMBUSTION AIR

Venting slots in the heating compartment access panel

remove the need for a combustion air hood. The gas heat

flue exhaust is routed through factory installed exhaust piping

with screen. If necessary, a flue exhaust extension may be

installed at the point of installation.

OPTIONS/ACCESSORIES

RAIN HOOD

All of the hood components, including the filters, the gasket-

ing and the hardware for assembling, are packaged and

located between the condenser coil section and the main unit

cabinet, if the unit has factory installed options. If field

installed accessories are being installed all parts necessary

for the installation comes in the accessory.

ECONOMIZER AND POWER EXHAUST SET POINT

ADJUSTMENTS AND INFORMATION

Remove the top rear access panel from the unit. Locate the

economizer control module, where the following adjustments

will be made.

MINIMUM POSITION ADJUSTMENT

• Check that the damper blades move smoothly without

binding; carefully turn the Minimum Position Adjust

screw (found on the damper control module) fully clock-

wise and then set the thermostat indoor fan switch to the

ON position and then OFF or energize and de-energize

terminals “R” to “G”.

• With the thermostat set to the indoor fan ON position or

terminals “R” to “G” energized, turn the Minimum Posi-

tion Adjusting screw (located on the damper control

module) counterclockwise until the desired minimum

damper position has been attained.

ENTHALPY SET POINT ADJUSTMENT

The enthalpy set point may now be set by selecting the

desired set point shown in the Enthalpy Set Point Adjustment

Figure 23. Adjust as follows:

• For a single enthalpy operation carefully turn the set

point adjusting screw (found on the damper control mod-

ule) to the "A", "B", "C" or "D" setting corresponding to

the lettered curve of the Enthalpy Set Point Adjustment

Figure 23.

• For a dual enthalpy operation, carefully turn the set point

adjusting screw fully clockwise past the "D" setting.

POWER EXHAUST DAMPER SET POINT (WITH OR WITH-

OUT POWER EXHAUST)

• With no power exhaust option, adjust the Exhaust Air

Adjustment Screw fully clockwise. This will allow 2nd

stage cooling to operate.

• With power exhaust option, each building pressurization

requirement will be different. The point at which the

power exhaust comes on is determined by the econo-

mizer damper position (Percent Open). The Exhaust Air

Adjustment Screw should be set at the Percent Open of

the economizer damper at which the power exhaust is

needed. It can be set from 0 to 100% damper open.

INDOOR AIR QUALITY AQ

Indoor Air Quality (indoor sensor input): Terminal AQ accepts

a +2 to +10 Vdc signal with respect to the (AQ1) terminal.

When the signal is below it's set point, the actuator is allowed

to modulate normally in accordance with the enthalpy and

mixed air sensor inputs. When the AQ signal exceeds it's set

point setting and there is no call for free cooling, the actuator

is proportionately modulated from the 2 to 10 Vdc signal, with

2 Vdc corresponding to full closed and 10 Vdc corresponding

to full open. When there is no call for free cooling, the damper

position is limited by the IAQ Max damper position setting.

When the signal exceeds it's set point (Demand Control Ven-

tilation Set Point) setting and there is a call for free cooling,

the actuator modulates from the minimum position to the full

open position based on the highest call from either the mixed

air sensor input or the AQ voltage input.

• Optional CO2 Space Sensor Kit Part # 2AQ04700324

• Optional CO2 Sensor Kit Part # 2AQ04700424

Replace the top rear access panel on the unit.

Extreme care must be exercised in turning all set

point, maximum and minimum damper positioning

adjustment screws to prevent twisting them off.

PHASING

Predator® units are properly phased at the factory. Check for

proper compressor rotation. If the blower or compressors

rotate in the wrong direction at start-up, the electrical connec-

tion to the unit is misphased. Change the phasing of the Field

Line Connection at the factory or field supplied discon-

nect to obtain proper rotation. (Scroll compressors operate in

only one direction. If the scroll is drawing low amperage, has

similar suction and discharge pressures, or producing a high

noise level, the scroll is misphased.)

BLOWER ROTATION

Check for proper supply air blower rotation. If the blower is

rotating backwards, the line voltage at the unit point of power

connection is misphased (See ‘PHASING’).

BELT TENSION

The tension on the belt should be adjusted as shown in Fig-

ure 25.

Scroll compressors require proper rotation to oper-

ate correctly. Units are properly phased at the fac-

tory. Do not change the internal wiring to make the

blower condenser fans, or compressor rotate cor-

rectly.

Procedure for adjusting belt tension:

1. Loosen six nuts (top and bottom) A.

2. Adjust by turning (B).

3. Never loosen nuts (C).

4. Use belt tension checker to apply a perpendicular

force to one belt at the midpoint of the span as

shown. Deflection distance of 4mm (5/32”) is

obtained.

To determine the deflection distance from normal

position, use a straight edge from sheave to sheave

as reference line. The recommended deflection

force is as follows:

Tension new belts at the max. deflection force rec-

ommended for the belt section. Check the belt ten-

sion at least two times during the first 24 hours of

operation. Any retensioning should fall between the

min. and max. deflection force values.
