 Emi Air Handlers With 

Unit mount infrared Controls

All service should be performed by a 

qualified  service  technician.  Before 

removing  access  panels  or  control 

covers  to  expose  moving  parts  of 

non-insulated  live  electrical  compo

-

nents for service, disconnect all high 

Volt power supplies to both the indoor 

unit and outdoor unit. Failure to do so 

could result in physical injury and/or 

electrical shock.

 

When trouble-shooting the indoor unit, 

please refer to the wiring diagram that is 

supplied with the equipment. It is located on 

the inside surface of the left end cap. (Also 

refer to 

Locate Electrical Wiring

 section 

in the front of this instruction.) If you are 

unable to locate the wiring diagram please 

feel free to call the factory technical service 

line at (800) 228-9364 and one can be faxed 

or mailed. Please have the full model and 

serial number available prior to calling.

 

EMI 

America Series

 evaporators are 

designed  to  operate  with  EMI 

America 

Series 

condensers. The evaporator (indoor 

unit) and condenser (outdoor unit) are to be 

independently connected to the electrical 

service  panel  and  protected  by  separate 

time delay fuse or HACR breakers. (See the 

unit name plate for the correct breaker type 

and size). The indoor and outdoor units are 

also connected to each other via a 24V inter

connect wiring. 

A

 

transformer

 

provides the 

low 

Volt power source for the controls. The 

number of low V

olt interconnect conductors 

will be two to six depending on heating op

tions and or thermostat selection. Intercon-

nect wire should be at least 18 awg. Refer to 

the unit wiring diagram for the interconnect 

diagram that matches your system.

when needed.

note:

 

Do not run the unit without the
