Packaged Make-Up Air
No Heat Models EM-MC00*, EM-MD00*, EM-ME00*, EM-MF00*, EM-MG00*
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
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.

Page 6: Safety Consideration
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. -
Page 7: Installation Overview
Installation Overview This Make-Up Air unit contains interface/logic devices, one current transformer (CT doughnut), inlet and outlet temperature sensors, power open/power close damper, permanent washable filter and blower motor. Based on the application, other system components may be required to make your system operate as desired. -
Page 8: Mechanical Installation
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. - Page 9 Horizontal installation – Ceiling Mount: Horizontal installation – Wall Mount: Option A: Cover Facing Down Option B: Cover Facing Side 07/29/2019 EI915...

Page 11: Electrical Installation
Electrical Installation Diagrams below represent general installation requirements. Due to various model sizes available, actual unit mechanical and wiring requirements will vary dependent upon specific model. Low Voltage Wiring Temperature Sensors Two temperature sensors are included, one used to sense inlet air temperature, the other to sense supply or outlet air temperature. -
Page 12: Control Wiring
Control Wiring There are two “tie-in” options available in connecting the Make-Up Air unit to a vent hood or other venting equipment. Option 1 – Connect an isolated “dry” switch or relay contact to the R & W terminal block (TB1). ... - Page 13 High Voltage Vent Hood Lighting Note: For multi-speed vent hood installations, consideration must be made with vent hoods that include higher wattage lighting. It is possible that the low speed trigger point of the fan is equal to or lower than the current draw of the integrated lighting in the vent hood itself.
- Page 14 4. Example – required three wraps, means the wire must go through the CT, loop back around, and then loop back around the second time through before it’s terminated at its original connection point. 5. The phasing or direction through the CT is not critical, simply one continuous wire. 6.
