withthe flanges to the insideand mustbe reversedbeforeunit's installation.

1. Remove the screws from the collars and reverse them so the flange

is to the outside.

2. Make sure when pushing the collars into place that the "V" flange of

the collars seats into the supply and return holes securely.

3. Re-install screw in each collar so it goes through both of the holes in

the collar end. It does not matter how the ends of the collar overlap

in order to accomplish this.

whenthethermostatcontactsclose.Approximately1to 20secondslaterthe indoorblower

and the first heater bankareenergized.Approximately70 secondsafter the first heater

bankis energizedthe remainingtime delaysand heaterbanks areenergized.

Staging

Some electric utilities require staging on electric heaters larger than 6 kilo-

watts. Therefore, the heater elements are turned on in 5 or 10 kW incre-

ments under control of the sequencers.

If staging based on heat loss or demand is required, the use of accessory

outdoor thermostats is recommended. The heat sequencer wiring is de-

signed to be staged by breaking the 24V "Common" Leg (normally brown

or gray). Outdoor thermostats available through your wholesale supplier

allow the control of two or four stages of electrical heat.

Some indoor electronic thermostats may provide for multiple stages of

electric heat. When this type thermostat is used, it may be necessary to

break the 24V "Hot" leg of the sequencer (as fed from the "W' circuit at the

thermostat). This will require field modification of the control wiring and

should only be done by an experienced controls technician or electrician.

Install Heater

1. Shut OFF electric power at unit disconnect switch or service panel.

2. Remove the blower access panel from unit.

NOTE: Installation of field wiring and conduit for heaters to the

unit prior to installing the heater will simplify wiring of heaters.

3. From inside the blower compartment, remove the six screws on the

heater cover plate and save the screws. Discard the heater cover

plate.

The screws will be used later to mount the electric heat accessory

and its cover.

4. Remove the cardboard wrapper from the heater's elements.

5. Insert the heater into the heater/blower box. Exercise caution to

prevent damage to heater elements.

6.Secure heater to heater/blower box with four of the six screws re-

moved in Step 3.

Grounding

Permanentlygroundthe electricheataccessoryin accordancewithlocalcodesandordi-

nancesandinthe UnitedStateswithNationalElectricalCodeANSIINFPA70-1990orcur-

rent edition. Use a copper conductor of the appropriate size from the electric heat

accessoryto the groundlug on the circuitbreakerpanel as shownin FIGURE10.

Installing Wiring

Whenan electricheataccessoryis installed,two separatefield powersupplies MUSTbe

provided - one or more forthe electricheat accessoryand one for the unit.

1.Shut OFF electric power at unit disconnect or service panel.

2.Installtheappropriatefieldsuppliedconduitfittingintotheheater

knockoutlocatedin the rear panel of the unit. The knockout is sized

11/4" in diameter.

NOTE: Check FIGURE 11 for heater/speed combinations that are

unacceptable.

3.Connect field installed copper ground wire(s) to the ground lug(s) on

the heater mounting plate. On models with more than one circuit, a

separate copper ground wire MUST be connected to a separate

ground lug for each circuit.

4. Route the field supplied line voltage wires for the heater to the line

side of the electric heat accessory's circuit breaker(s) or high voltage

wiring harness. Leave approximately 8" of excess wire so the break-

er or wiring harness may be moved to service. Make line voltage

connections to L3-L6 as appropriate. NOTE: If heaters without

breakers are used, route field wires to inside of unit and attach to

heater wires tagged L3-L6 as appropriate using supplied wire nuts.

5.Connect the black wire with terminal from the heater wire harness to

the loose black wire at the unit blower or appropriate speed tap if

lower speed is desired in electric heat mode.

FIGURE 10 1

6 Connect the red wire with terminal in the heater wire harness to the

loose red wire from the unit sequencer.

7.Connect the white wire from the heater wire harness to the white wire

from the thermostat at the field supplied low volt wire harness in the

control box.

8.Connect the grey and brown wires from the heater wire harness to

the blue wire from the unit 24V common. NOTE: If outdoor thermo-

stats are used for staging electric heat, connect the grey and brown

wires according to the thermostat instructions. See "Staging" in

Electrical Wiring Section of this Manual.

After completing installation of the heater, install the breaker rain shield on

the blower access panel according to the following instructions on page 8.

If using a pigtail style heater, proceed to Start-Up Procedures for Auxiliary

Circulating Air Blower

DeterminingBlowerSpeed

1.Turn electric power OFF.

2. From the system design, determine the total external static pressure

(ESP) for the supply ducts, return ducts and registers, diffusers,

grilles, dampers, heaters and filters.

3.To your system ESP determined in Step 2, add 0.05 In. W.C. for a

wet coil.

4. From the system design, determine the desired cooling airflow in

cubic feet per minute (CFM).

5. Locate the unit's Blower Performance Data table on the tech data

label for the unit's voltage. (The tech data sheet is attached to the

evaporator access panel on the unit.) From the table, determine the

speed tap required to achieve the desired airflow.

&See next section, Speed Taps, to set the blower motor speed termi-

nal block (speed taps) to the cooling speed determined in the pre-

vious steps.
