Multi-zone Heat Pump Condensing Units

ELECTRICAL WIRING INSTALLATION SECTION

3. Use only HACR type breakers or time 

delay fuses. Select the wire size accord-

ing to the ampacity rating. 

4.  To  access  electrical  connections  and 

wiring diagram:
a) Remove the screws on the side panel 

adjacent to the back panel.

b)  The  screws  adjacent  to  the  front 

panel should already be loose (don't 

remove them).

1. All electrical wiring must be run according 

to NEC and local codes. 

2. Refer to the unit rating plate for voltage, 

minimum circuit ampacity and over cur-

rent protection requirements. 

c. Slide the side panel out to access the 

high/low  electrical  connections  and 

wire diagram.

Note:

 Remove the plastic edge guards 

from the holes and replace with a water-

tight 

strain relief fitting

 (High V) and a 

split grommet fitting (Low V)

5. Power should be run to a weather proof 

disconnect box usually within 3 feet of 

the unit.

6. From the disconnect box, run the power 

through the 7/8" hole on the side of the 

unit and into the electrical box and an-

chor with the strain relief fitting. 

7. Run wires to the high Volt pigtail in the con-

trol box and attach L1 and L2 connections. 

Also run green wire to ground wire.

The  EMI   America  Series  condensing 

unit must:

• Be connected to a properly grounded 

electrical supply with the proper voltage 

as stated on the rating plate.

• Have proper over current protection (i.e. 

time- delay fuse/HACR-Breaker) as listed 

on the Rating Plate.

Failure to follow these instructions can re-

sult in a fire, explosion, or electrical shock 

causing property damage, personal injury, 

or death.

 DANGER

!

  

 

Do  not  use  the    EMI   America  Series 

condensing unit with any electrical supply 

voltage other than the one listed on the 

rating plate.
Check the rating plate on the unit for the 

correct voltage rating.  Failure to use the 

correct voltage may result in death, serious 

bodily injury or property damage.  If you have 

any questions or doubts, consult the factory 

before installing this unit.

 DANGER
