Electrical shock hazard.

General Information

Shut OFF electric power at unit disconnect and/or service
panel before beginning the following
procedures.

Installation or repairs made by unqualified persons can result
in hazards to you and others. Installation must conform with
local building codes or, in the absence of local codes, with
National Electrical Code ANSI/NFPA 70-1990 or current
edition.
The information contained in this manual is intended for use
by a qualified service technician
familiar with safety
procedures,
equipped
with the proper tools and test
instruments.
Failure to carefully read and follow all instructions in this
manual can result in malfunction, property damage, personal
injury, and/or death.

Failure to follow this warning can result in property damage,
personal injury, and/or death.

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.
When an electric heat accessory

is installed, two separate field power

supplies MUST be provided - one or more for the electric heat accessory
and one for the unit.

5.Insert the heater into the heater/blower

trois which operate through the low voltage thermostat

switch (when

required) located within sight ofthe unit. Supply voltage, amperage, fuse
and disconnect switch sizes MUST conform with all technical specifications in this manual and on the unit rating plate and local codes.
Wiring MUST be protected from possible mechanical damage and MUST
NOT interfere with removal of access panels, filters, etc.
All exposed wiring or connections MUST be made with weatherproof
cable or wire unless installed in conduit.
and the ground connection

MUST be made

with copper wire.

These controls consist of a number of time delays depending on the specific heater model. An electric heat accessory

has 1,2 or 3 of these con-

trois. The first time delay is activated when the thermostat contacts close.
Approximately

1 to 20 seconds later the indoor blower and the first heater

bank are energized. Approximately

70 seconds after the first heater bank

is energized the remaining time delays and heater banks are energized.

Staging
Some electric utilities require staging on electric heaters larger than 6 kilowatts. Therefore, the heater elements are turned on in 5 or 10 kW increments under control of the sequencers.
If staging based on heat loss or demand is required, the use of accessory

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

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 thermostats 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

13. If using a pigtail style heater, proceed to Start-Up Procedures for Auxiliary Electric Strip Heat on page 14.

Speed Taps
After determining the required CFM andspeed tap data from the tech data
sheet, follow the steps below to change speeds if necessary.

NOTE: The cooling, heat pump and strip heat airflows are all on the same
speed tap. The refrigerant system requires the same specific CFM for
proper operation in the cooling and the heat pump mode. For this reason,
cooling and heating airflow must be the same. DO NOT SPLIT OUT INTO
A COOLING SPEED AND HEATING SPEED. If auxiliary electric heat is
installed, the auxiliary electric heat blower speed wire must be connected
to the black wire insulated quick connect terminal.
