7. One line voltage “EAC” 1/4" spade terminal is provided

on the furnace integrated control.  Any electronic air

cleaner or other accessory rated up to one amp can be

connected to this terminal with the neutral leg of the

circuit being connected to one of the provided neutral

terminals.  See Figure 537 for control configuration.  This

terminal is energized when the indoor blower is

operating.

8. One line voltage “HUM” 1/4" spade terminal is provided

on the furnace integrated control.  Any humidifier rated

up to one amp can be connected to this terminal with

the neutral leg of the circuit being connected to one of

the provided neutral terminals.  See Figure 53 for control

configuration.  This terminal is energized in the heating

mode whenever the combustion air inducer is operating.

9. Install the room thermostat according to the instructions

provided with the thermostat.  If the furnace is being

matched with a heat pump, refer to the instruction

packaged with the dual fuel thermostat.

Indoor Blower Speeds

1. When the thermostat is set to “FAN ON,” the indoor

blower will run continuously at approximately 50% of

the second stage cooling speed when there is no cooling

or heating demand.

2. When this unit is running in the heating mode, the indoor

blower will run on the heating speed designated by the

positions of DIP switches 1 (A,B,C,D) of the HEAT

jumper plug.

3. When there is a cooling demand, the indoor blower will

run on the cooling speed designated by the positions of

DIP switches (A, B, C, D) of the COOL jumper plug.

Generator Use - Voltage Requirements

The following requirements must be kept in mind when

specifying a generator for use with this equipment:

•

The furnace requires 120 volts ± 10% (Range: 108 volts

to 132 volts).

•

The furnace operates at 60 Hz ± 5% (Range: 57 Hz to

63 Hz).

•

The furnace integrated control requires both polarity and

proper ground.  Both polarity and proper grounding

should be checked before attempting to operate the

furnace on either permanent or temporary power.

•

Generator should have a wave form distortion of less

than 5% RHD.

Electrical Wiring

Risk of electrical shock. Disconnect electrical power at

the circuit breaker or service panel before making

electrical connections. Failure to disconnect power

supplies can result in property damage, personal injury,

or death.

The furnace must be grounded and wired in accordance

with local codes or, in the absence of local codes, with the

National Electrical Code ANSI/NFPA No. 70 (latest edition)

and/or CSA C22.1 Electrical Code (latest edition) if an

external electrical source is utilized.

In all instances, other than wiring for the thermostat, the

wiring to be done and any replacement of wire shall conform

with the temperature limitation for Type T wire –63°F (35°C)

rise.

Connect a sufficiently sized wire with ground to the furnace’s

line voltage connections and ground wire.  Refer to the

furnace rating plate for electrical characteristics to be used

in sizing field supply wiring and overcurrent protection.

The line voltage supply should be routed through a readily

accessible disconnect located within sight of the furnace.  A

junction box on the furnace side panel is provided for line

voltage connections.  Refer to the furnace wiring diagram

for specific connection information.

Proper polarity of the supply connections (“HOT” and

“NEUTRAL”) must be observed to ensure that safety

controls provide the protection intended.

A connection to the unit’s ground wire and actual earth ground

(typically a ground stake or buried steel pipe) must be

maintained for proper operation.

Thermostat

Install a room thermostat according to the instructions

furnished with it.  Select a location on an inside wall that is

not subject to drafts, direct sunshine, or other heat sources.

The initial heat anticipator setting should be equal to the

total current draw of the control circuit.  Low voltage

thermostat connections are to be made to the integrated

ignition/blower control board as indicated on the wiring

diagram.
