Recognize safety information. This is the safety-alert symbol
/_. When you see this symbol on the furnace and in
instructions or manuals, be alert to the potential for personal
injury. Understand the signal words DANGER, WARNING,
CAUTION and NOTE. The words DANGER, WARNING, and
CAUTION are used with the safety alert symbol. DANGER
identifies the most serious hazards which will result in severe
personal injury or death. WARNING signifies a hazard which
could result in personal injury or death. CAUTION is used to
identify unsafe practices which may result in minor personal
injury or product and property damage. NOTE is used to
highlight suggestions which will result in enhanced installation,
reliability, or operation.

NOTE: EHIA electric heaters are not backwards compatible with
any of the previous MF or MV models prior to B1.
NOTE: Supply voltage, amperage, fuse and disconnect switch
sizes MUST conform with all technical specifications in this manu-
al and on the unit rating plate.
Adapter and filler plates are shipped with the indoor units to be
used with electric heat as needed depending on unit size and
heater size.

ELECTRICALSHOCK HAZARD
Failure to follow this warning could result in personal injury or
death.
Before installing, modifying, or servicing system, main
electrical disconnect switch must be in the OFF position and
install a lockout tag. There may be more than one electrical
supply to the furnace. Check accessories and cooling unit for
additional electrical supplies that must be shut off during
furnace servicing. Lockout and tag switch with a suitable
warning label. Verify proper operation after servicing.
1. Shut OFF electric power at unit disconnect switch or ser-
vice panel.
CUT HAZARD
Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care
and wear appropriate clothing, safety glasses and gloves when
handling parts and servicing furnaces.
2.
3.
Remove the front panel from unit and locate adapter and fill-
er plates, with screws inside package.
Attach adapter plate and filler plate to heater if required to
match opening in cabinet.

Right Hand Airflow Application Only/Heaters with CB.
If indoor section is going to be used for right hand airflow,
the circuit breakers will have to be removed and rotated
180°, so the OFF position will be DOWN when the cabinet
is positioned on the right side. This isan NEC requirement.
DO ONE SET OF BREAKERS AT A TIME to make sure
wires are reconnected properly, Loosen terminal screws
on the wires and gently pull wires back from breaker. Re-
move screws securing breaker and rotate 180°,then recon-
nect wires to breaker. Proper torque for terminal screws is
35 inch pounds.
Insert the heater into the cabinet opening as shown in
Figure 1, so the heater support rod goes into the hole in
back of the cabinet. Exercise caution to prevent tearing
of insulation or damage to heater element,
Secure the electric heat accessory with four screws.
Connect the 9-pin heater wiring harness to receptacle loc-
ated inside cabinet. A perfect match and positive connec-
tion must be made between the plug and receptacle. The
plug will interlock with receptacle when properly seated.
Harness contains both 24V and high-voltage wiring.
Blower power is provided through heater harness.
Install front door panel. NOTE: If the heater has circuit
breakers, remove the appropriate knockout(s) in the door
panel to match circuit breaker location. Clean the perimeter
area around the opening. If greasy or highly soiled use alco-
hol to clean the area.
Circuit Breakers Models only: Remove backing from the
circuit breaker cover seal and align it with the embossed
area so it covers the circuit breakers. Press firmly around
the edges so itseals properly. Seal helps to minimize mois-
ture infiltration which can affect electronic components.
10. Mark an "X" in the appropriate box for the heater on the in-
door unit rating plate.

Wiring
All line voltage connections and ground connections MUST be
made with copper wire.
The power supply wiring MUST have overcurrent protection. This
can be either fuses or circuit breakers. The maximum size for the
overcurrent protection is shown in the column labeled "Max. Fuse
or NEC HACR Breaker (Amps)" inthe Electrical Data Table or on
the unit rating plate.
Connect supply voltage wires to the Circuit Breakers on the heater
or to the terminal block on the heater. Power for the blower motor is
supplied through the connector from the heater to the control
board.
Grounding
Permanently ground the electric heat accessory in accordance
with local codes and ordinances and in the United States with Na-
tional Electrical Code ANSI/NFPA70-2011 or current edition. Use
a copper conductor of the appropriate size from the electric heat
accessory ground lug, to a grounding lug on the circuit breaker
panel. On models with more than one circuit, a separate copper
ground wire MUST be connected for each circuit.
ELECTRICAL SHOCK HAZARD
Failure follow this warning could result in personal injury
or death.
The unit cabinet must have an uninterrupted or unbroken
ground to minimize personal injury if an electrical fault
should occur. The ground may consist of electrical sire
or metal conduit when installed in accordance with
existing electrical codes.
Heater Staging
The electric heater elements and modular blower controls are
factory circuited for single-stage electric heat operation. Refer to
Electric Heat Staging Table A-1 for all available heaters. On larger
heaters the electric heat can be staged (1st & 2nd and/or 3 rd) via
the indoor wall thermostat, or by using an accessory ODTS (out-
door thermostat temperature switch). Controlled heater staging
may satisfy requirements imposed by some electric utilities. Re-
fer to Table A-2 for two-stage capable heaters and Table A-3 for
three-stage capable heaters. Refer to the indoor modular install-
ation instructions for suggested low-voltage control wiring regard-
ing staging.
Rectifier and Time Delay Boards
Each heater element is controlled by a relay mounted on the heat-
er panel. The relay has a 24V DO coil. Each relay has a small recti-
fier board attached directly to the relay coil terminals. The rectifier
board converts incoming 24V AC control signal to DC. Some
heaters may have up to three relays. Both the second and third
(relay) rectifier boards have a built-in R2 jumper time-delay fea-
ture. When the jumper is uncut, the time delay allows the second
stage heat to be energized approximately five (5) seconds after
the first stage. On 20kW and 25kW heaters models (table A-3),
the third-stage relay R2 jumper is factory cut. This provides an
eight (8) second delay after first stage relay closes.
Air Flow
Air flow requirements are different between MF and MV. Refer to
MF and MV Installation Instructions for airflow set-up information.
Temperature Rise Check
Temperature rise is the difference between the supply and return
air temperatures.
NOTE: The temperature rise can be adjusted by changing the
heating speed tap at the unit's blower terminal block. Refer to the
unit's Installation Instructions for airflow information.
A temperature rise greater than 60°F (33.300) is not recom-
mended,
1. To check the temperature rise through the unit, place ther-
mometers in the supply and return air ducts as close to the
unit as possible,avoiding direct radiant heat from the heater
elements.
2. Open ALL registers and duct dampers.
3. Set thermostat Heat-Cool selector to HEAT.
4. Set the thermostat temperature setting as high as it will go.
5. Turn electric power ON.
6. Operate unitAT LEAST 5 minutes, then check temperature
rise.
NOTE: The maximum outlet air temperature for all models is
200°F (93.3°C).
7. Set thermostat to normal temperature setting.
8. Turn electric power OFF.
9. Be sure to seat all holes in ducts if any were created during
this process.
