Type
All models – ECM™ blower motor, setup selection of four cooling sizes, 50% continuous air (fan – on
setting). High efficient air circulation at about 50-watt.
H= Full WarmFlo capability with outdoor sensor. This provides warm air outlet temperature dial
selection and supply air ramp up with the decrease of outdoor temperature. This WarmFlo
feature definitely applies to heat pumps, but it is also the top of the line comfort for straight
electric, with air conditioning. The warm air dial suggested setting is 96° or 100° and the front
dial selects the rate of ramp up or temperature increase based upon outdoor. The “C” setting
will provide 114° warm air at 0° or 125° at -20° F outside. The ECM™ blower also ramps up
in speed as there is an increase in supply temperature or decrease in outdoor temperature.
Depending upon setup selection, the moderate heating blower speed could be as low as 60% of
full capacity and full capacity blower is only used below 30° outdoor.
Heat/cool conventional or basic heat pump room thermostat can apply.
A= WarmFlo element modulation based upon a front panel set point and duct sensor. Heating
blower speed is installation setup per kW size. A higher CFM selection can be made if there is
a desire to “work” WarmFlo harder.
Heat/cool conventional thermostat applies.
E= Non-WarmFlo, 10, 15, or 20 kW built-in strip heat, direct function of roomstat W. Setup
selection determines nominal ECM™ motor speed. A thermostat “E” type function could be
used to jump to full speed.
N = Electric Furnace cabinet only, no electric elements or WarmFlo. This could typically be
associated with an inlet hydronics water coil. Control board includes a relay for pump, initiated
with input W. Setup selection determines heating blower speed. Cooling speeds and air
conditioning interface are the same as mentioned above.
Note: Two-speed and multi-function room thermostat can also be configured with this system by adding
WF-HP2 interface controller.

02/14/2006 2 NI806
Inlet Cabinets
Factory optional cabinets can be configured with this Electric Furnace. Typically these are designed for
upflow applications; however, the heat pump coil cabinet could be used in other positions.
Side Entry, Filter Cabinet
Return air can be ducted into either side, 15-⅜” x
19” cutout hole is provided with one filler plate.
Easy access door for checking and changing filter.
Adjustable rails are provided for standard 4” x 20”
x 20” pleated filter.
Filter examples include Honeywell 203721, BestAir
HW2020, or Grainger®6B936.
Standard 1” filter (20” x 20”) – field installer could arrive at filter filler bracket for slip-in within the
provided rails.
Comment – The 3M MERV filter airflow resistance needs to be considered in duct design
calculations. Per specification information from 3M the static pressure drop across the 1”, Series
1000, MERV 11 filter is 0.2” SP.
Hydronics Coil and Cabinet
The inlet cabinet includes a water coil with
parameters shown. The return air connection must
be on a side which allows coil draw-through. The
cabinet can be reversed for either left or right side
entry. The inlet for this cabinet is sized for an
externally installed packaged return air filter cabinet
– typical 20” x 20” size.
1. Nominal or rated Btu/h, 50,000
2. Recommended CFM setup, 1100 min.
3. Inlet water 120° at 10 GPM minimum.
4. Expected outlet air temperature, 115°
Reduced CFM and/or inlet water temperature will
reduce Btu/h rating.

General Comments
Upflow/Downflow/Horizontal
The arrangement of refrigerant coil, hydronics coil, and built-in electric elements need to follow specific
air direction or airflow rules, but the orientation of this Electric Furnace is not critical.
For upflow and horizontal standard air conditioning applications, the A-coil is mounted at the blower
outlet with field provided plenum or manufacturer’s case coil.
All models contain GE ECM™ Series 2.3 blower motors. The special Electro Industries interface board
allows hookup for heat/cool conventional or basic heat pump room thermostat. Blower speed setup and
WarmFlo sensor control are separate for cooling and heating (unique).
The ECM™ motor provided in this unit has many features not available in a standard motor.
-Improved efficiency
-Constant CFM
-Soft start and stop
-Better humidity control
The provided ECM™ motor contains permanently sealed bearings and does not require oiling.
Utility Load Control
Provisions also included for the Utility Receiver to interrupt compressor and WarmFlo or strip heat. No
provisions for dual heat, add EE-5046.
Side by Side, with Gas Furnace or Other Dual Heat Arrangements
Add-on dual heat controller HP-5046 can simplify the wiring for dual heat.
For side by side ducting, a motor operated damper is required to isolate the return air between two
blowers. The operation of this motor damper can be controlled from the HP-5046.
Installation Setup
There are specific peg jumpers relating to cooling tons, heating kW, heat pump reversing valve logic, and
thermostat type. These must be properly evaluated and selected to match each installation.
The “setup or programming” section has all the detailed instructions and selection tables.
The WarmFlo controller also has various dial switch selections relating to duct temperature set point,
minimum warm air set point, HP compressor ODT shutoff temperature, and ramp up efficiency dial.
These are standard WarmFlo technology and setup requirements, if you’re not familiar with WarmFlo
controller study the HD320 WarmFlo information document, also in this package.
NOTICE: When changing any setup jumpers, power down and up. ECM™ motor needs 240V power
and control power removed to reset and reread specific control lines. Open CB number 1 for 10 seconds.
Operation Instructions
The “Operation Indicators” section contains information relating to LED monitor lights, thermostat
sequences, etc.

Mechanical Installation
Clearances and Accessibility
Zero clearance is allowed on all sides for combustible materials. However, 36” should be allowed at the
front for operation, maintenance, and service.
To reduce the risk of rusting and appearance, do not install the unit directly on the ground or on a floor
that is likely to be wet. In such environments the unit must be elevated by use of a sturdy non-porous
material.
General Ductwork and Airflow Requirement
Design the airflow ductwork to meet the maximum operating airflow (CFM) for the kW and cooling ton
requirements (whichever is larger). This document does not provide installation and design information
for the ductwork external to this product. It is assumed this is being accomplished by a professional and
trained installer understanding ductwork design, airflow/static pressure resistance, and forced air
distribution systems. Key requirements information:
-Heating and cooling blower speed or minimum CFM is setup independently. See the “Blower
Speed Selection” to match the airflow capacity with the ducting design.
-The airflow distribution system shall be designed for a maximum of 0.5” SP. Ideally the design
should be set at 0.3” to 0.4” SP.
-The variable speed, ECM™ motor, is sensitive to inlet static pressure. In order for the motor to
arrive at the setup CFM (motor RPM adjust according to static pressure) the inlet must have a
minimum resistance of about 0.15 to 0.2. If you do not have return air ducting and you’re simply
allowing free return air circulation through a filter at this Electric Furnace inlet, you may need to
have a slight restriction in order for the blower motor to arrive at its setup speed.
-All transitions must have a slope of 30° to 45°. There shall be no 90° bends or surfaces causing
airflow bounce/eddy current.
-The manufacturer strongly recommends the return air entering the bottom (under the blower) of
the cabinet. For smaller kW and smaller cooling (10 kW or 2-ton) it is permissible to bring the
air in on either side of the 32” cabinet.
-Previous Specification Chart shows the minimum CFM associated with the kW. Again this is
setup as detailed in the “Setup or Programming” section.
-The cooling CFM is also selected but is not shown on the Specification Chart. In many cases the
airflow distribution system is probably designed to meet the cooling requirement.
-The room registers and individual 5” or 6 “ runs must also match the total setup or planned CFM
for this installation. Typically a 6” round and a typical room register is rated at 100 CFM.
-All distribution ducts (supply and return) must be sized for the setup or planned total CFM
requirement. The attached duct sizing chart shows various distribution duct sizes relating to their
ability to properly handle the stated CFM.
-Seal connections between this unit and ductwork, all ductwork connections, etc. as required to
reduce or eliminate air leakage. Sealing all connections will also reduce air noise.
Comment: The ECM™ motor efficiently relates to system static pressure. On one hand a minimum of
about 0.2” SP is required for the motor to adjust itself, but above 0.3” it begins to drain high current. For
information, consider (at 240):
1.0” SP – 3.4A
0.8” SP – 2.5A
0.5” SP – 0.9A
0.2” SP – 0.4A
Continuous Air – 0.25A

02/14/2006 8 NI806
Whether this unit is sitting on or attached to an inlet cabinet, field designed inlet cabinet, or horizontal
supports; verify proper support and mechanical strength is provided within the system installation.
Rubber isolation pads should be used where possible to reduce sound and vibration transmission.
WARNING
WHEN HANGING THIS UNIT, THERE MUST BE UNDER SUPPORTS WHICH DISTRIBUTE THE
HANGING CHAINS ACROSS THE SURFACE OF THIS UNIT, DO NOT SIMPLY DRILL A HOLE
AND USE A COUPLE OF HANGING BOLTS.
For information, factory optional inlet cabinets can reduce cost and simplify installation, see previous
pages.
When installing the unit maintain a minimum clearance of 36” in front of the unit for service accessibility.
Upflow, Air Conditioning
As stated above, the return air should enter the bottom of this cabinet. Suggest using Electro bottom filter
cabinet (page 2) or field constructed equivalent. The A-coil will be mounted above the blower in either a
case coil or field constructed plenum.
Upflow, Heat Pump
In this case the HP refrigerant coil must be at the bottom of the blower in order for WarmFlo to properly
add temperature to the heat pump output. Electro inlet cabinet is ideal for using a heat pump A-coil (page
2). This factory available inlet cabinet provides space for standard A-coil and is installed between the
filter/inlet cabinet and the Electric Furnace unit itself.
The cabinet is designed for 20”H A-coil, but for larger A-coils the top can be above this cabinet
approximately 3” (24”).
The outlet of the blower will enter into a plenum and directly into distribution duct.
Downflow, Air Conditioning
Similar to upflow above, the air conditioning coil is positioned at the blower outlet. Depending upon the
coil type and drip pan it is positioned in a field constructed plenum as required.
A typical packaged 20” x 20” filter cabinet could easily be installed at the blower inlet opening.
Downflow, Heat Pump
With the WarmFlo elements down and airflow direction down, the A-coil must be at the top of this unit.
The factory option Heat Pump Coil Cabinet can be used for coils less than 20” high. This is assuming the
heat pump and associated refrigerant coil you are using is designed to drive air “backwards” through the
A-coil and drip pan. Use heat pump manufacturer’s recommendation; however, refrigerant coil must be
on the inlet side of the elements.

02/14/2006 9 NI806
Horizontal, Air Conditioning
Similar to upflow above, the air conditioning coil is positioned at the blower outlet. Depending upon the
coil type and drip pan it is positioned in a field constructed plenum as required.
As horizontal, the return air would enter the blower end of the cabinet with a typical packaged 20” x 20”
filter cabinet.
Horizontal, Heat Pump
As emphasized above, the heat pump coil must be at the blower inlet. Depending upon the coil physical
arrangements and drip pan, it is installed in a field constructed plenum at the blower inlet.
Typically a package filter cabinet is installed at the entrance (or ahead of) of the HP coil.
The blower outlet goes directly into the distribution duct system.
Blower Motor Orientation
If the installation is not upflow, the blower motor shall be positioned so the power and control connectors
are down. This will prevent water from entering the blower motor through the connector housing
opening.
Loosen motor mount clamp and rotate motor accordingly.
Before tightening motor mount clamp be sure the blower wheel is properly centered inside the blower
housing.
