DANGER

Tampering with this unit is danger-

ous

. Tampering voids all warranties. 

DO NOT

 att empt to modify or change 

this unit in any way.

 

 

   

DANGER

Th

  e EMI unit must:

Be connected to a properly grounded 

• 

electrical supply with the proper 
voltage as stated on the rating plate.
Have proper overcurrent protection 

• 

(time-delay fuse/HACR Breaker) as 
listed on the rating plate.

Ensure there are no power feeds to the 
unit such as fire alarm circuits, BMS 
circuits, etc.

Failure to follow these instructions can 
result in a fi re, explosion, or electrical 
shock causing property damage, personal 
injury, or death.

 Safety 

Instructions

Th

  is manual is intended as an aid to quali-

fi ed service personnel for proper installa-
tion, operation, and maintenance of the 
EMI Series  high effi

  ciency air handler.  

Read these instructions thoroughly and 
carefully before att empting installation or 
operation.

Failure to follow these instructions may 
result in improper installation, operation, 
service, or maintenance, possibly resulting 
in fi re, electrical shock, property damage, 
personal injury, or death.

unit.  Install or locate this unit only in ac-
cordance with these instructions.  Use this 
unit only for its intended use as described 
in this manual.

Check the rating plate on the unit before 
installation to make certain the voltage 
shown is the same as the electric supply to 
the unit. Th

  e rating plate is located on the 

top panel only. 

This unit must be connected only to a 
properly grounded electrical supply.  Do 
not fail to properly ground this unit.

Turn off  the electrical supply before servic-
ing the unit.

Do not use the unit if it has damaged wir-
ing, is not working properly, or has been 
damaged or dropped.
