Included With This Product
Permanent washable air filter
Powered inlet damper
(2) temperature sensors
(1) current transformer (CT doughnut)
Chain kit for ceiling installations
Other Requirements
Low voltage (Class II type) wiring when using supply CT doughnut to control Make-Up Air unit
High voltage wiring
Fresh air intake wall or roof vent
Inlet/outlet ductwork
Application
This product aids in preventing building depressurization where there is single or multi-source exhaust
points, coupled with a tight building envelope such as:
Single, large exhaust source
- Kitchen range hood
Single or multi-speed exhaust blower interface
Multiple exhaust sources
- Bathroom fan, fireplace, dryer, gas furnace, dryer, etc.
Note
In applications where the exhaust fan utilizes a multi-speed blower, this product has the ability to
sense each fan speed by monitoring the amperage of the exhaust fan motor. After completing the
mechanical portion of the installation, see Multi-Speed Setup for further details explaining how
to utilize this unique feature. Configuring the Make-Up Air unit to vary its speed to closely match
the blower speed of the external exhaust source blower motor allows for balanced system
operation.

Product Description
This is a self-contained package with a permanent (washable) air filter, powered damper and blower. This
product has been designed specifically for outside air inlet.
All models (except EM-MB) include a multi-speed blower function; see Basic Setup & Configuration
for further detail.
Diagrams used throughout the installation manual represent general installation requirements. Due to
various model sizes available, actual unit mechanical and wiring requirements will vary dependent upon
specific model.
Handling & Storage
Receiving
It is the receiver’s (person and/or company signing off on the receiving Bill of Lading) responsibility to
inspect for shipping damage. All shipping claims must be made by the receiver.
Storage
Packed or unpacked, the Make-Up Air unit shall not be exposed to rain, snow, or other adverse
environment. This product is designed for in-building storage and installation only.
As much as possible this product must be protected throughout the construction phase to avoid
accumulation of dust and moisture on the components and control box. The installing contractor is
responsible for maintaining the cleanliness and quality of this unit until installation is complete and
approved by the user/end customer.
Placement & Mechanical Information
This product is designed for zero clearance, but use the following mounting and spacing criteria:
1. Unit can be installed vertically or horizontally. When vertical, inlet must face down.
2. When using CT doughnut, use Class II low voltage wiring methods to connect CT to Make-Up
Air unit.
3. Make mounting provisions for a 1” air space at the top.
4. The sides, any location, can be in direct contact with wood framing materials.
5. No materials shall be in contact with the cabinet housing which has a flame point less than wood,
300°F (150°C).
6. Product shall be installed in a conditioned space only.

Safety Consideration
WARNING
BEFORE PERFORMING SERVICE OR MAINTENANCE OPERATIONS ON A SYSTEM, TURN OFF
MAIN POWER SWITCHES TO THE INDOOR UNIT. IF APPLICABLE, TURN OFF THE ACCESSORY
HEATER POWER SWITCH. ELECTRICAL SHOCK COULD CAUSE PERSONAL INJURY.
Installing and servicing electric heating equipment can be hazardous due high voltage and electrical
components. Only trained and qualified service personnel should install, repair or service heating and air
conditioning equipment. Untrained personnel can perform the basic maintenance functions of cleaning
coils and cleaning and replacing filters. All other operations should be performed by trained service
personnel. When working on heating and air conditioning equipment, observe precautions in the
literature, tags and labels attached to the unit and other safety precautions that may apply, such as the
following safety measures:
Follow all safety codes.
Wear safety glasses and work gloves.
Installation Requirements
1. All installation work must be performed by trained, qualified contractors or technicians. Electro
Industries sponsors installation and service schools to assist the installer. Visit our Website at
www.electromn.com for upcoming service schools.
WARNING
ALL ELECTRICAL WIRING MUST BE IN ACCORDANCE WITH NATIONAL ELECTRIC CODE AND
LOCAL ELECTRIC CODES, ORDINANCES, AND REGULATIONS.
WARNING
OBSERVE ELECTRIC POLARITY AND WIRING COLORS. FAILURE TO OBSERVE COULD CAUSE
ELECTRIC SHOCK AND/OR DAMAGE TO THE EQUIPMENT.
CAUTION
This unit can only be used for its intended design as described in this manual. Any internal
wiring changes, modifications to the circuit board, modifications or bypass of any controls, or
installation practices not according to the details of this manual will void the product warranty,
the safety certification label, and manufacturer product liability. Electro Industries cannot be
held responsible for field modifications, incorrect installations, and conditions which may
bypass or compromise the built-in safety features and controls.
CAUTION
This unit shall not be operated (either heating section or blower) until the interior of the
structure is completed and cleaned. This also means all duct work must be complete with
filter, etc. Manufacturer’s warranty is void if this unit is operated during structure
construction.
CAUTION
Hazards or unsafe practices could result in property damage, product damage, severe personal
injury and/or death.
2. At Electro Industries the safety of the installer and the end user is of highest priority. Remember,
safety is the installer’s responsibility and the installer must know this product well enough to instruct
the end user on its safe use. Professional installers should be trained and experienced in the areas of
handling electrical components, sheet metal products, and material handling processes.

Mechanical Installation
This product is designed for zero clearance, but use the following mounting and spacing criteria:
1. Unit can be installed vertically or horizontally. When vertical, inlet must face down.
2. When using CT doughnut, use Class II low voltage wiring methods to connect CT to Make-Up
Air unit.
3. The sides, any location, can be in direct contact with wood framing materials.
4. No materials shall be in contact with the cabinet housing which has a flame point less than wood,
300°F (150°C).
5. Product shall be installed in a conditioned space only.
General:
1. Select a location which will provide minimal noise vibration and minimal blower noise to the
building occupants.
2. The outside hood and ducting material are not included with this unit. It is the installer’s
responsibility to provide the necessary weather protection for the inlet.
In cold climates, insulated ducting must be used between the outside inlet air hood and the
inlet of this unit.
3. Install unit with a slight air inlet incline (housing outlet end is ¼” higher than inlet end).
4. The unit can be mounted within the ceiling (between joists where it will fit) or ceiling hung, at
any convenient location between the outside inlet hood and the fresh air discharge connection.
The “discharge connection” is wherever the conditioned fresh air is distributed within the
building – furnace cold air return, special ducting, hallway register, etc.
5. The inlet and outlet ducting size is specified according to the model size and is shown in the
Dimensional Drawings section of this manual.
Note: In cold climates, frost and or condensation may collect on metal parts of this product. External field
provided insulation may be required in certain situations. The inlet damper and insulated inlet piping will
prevent cold air migration and a slight incline will keep moisture collection at the inlet end.
