Mounting the Air Conditioner 
 

Using the template supplied, determine where the air conditioner is to be mounted and assure that all 
required cuts and holes will not interfere with or damage the enclosure or its contents.  Assure that 
there is a 3

” clearance between walls / obstructions and the air conditioner for the condenser supply 

air and return air flow so that it is not restricted.  Restricted condenser air flow will affect the air 
conditioner’s performance.  Mount the air conditioner high on the enclosure in order to cool the hot air 
in the top of the enclosure.  Position the unit where the cold air can circulate across the width of the 
enclosure to cool it all the way across.  
 
Once proper mounting placement is determined, turn the enclosure equipment off, if possible, to 
prevent damage.  Drill and cut the holes as indicated on the mounting template.  Install insulation 
gasket as required to ensure an air tight closed loop seal.  Be cautious not to let any cutting debris fall 
into the enclosure.   
 
Hang the air conditioner on the Easy Hang Mounting Tabs and from inside the enclosure use the 
fasteners supplied to attach the air conditioner to the enclosure.  Screw all fasteners hand tight. Then 
torque to 96 in-lbs.  These fasteners should be checked periodically to ensure that they have not 
become loose due to vibration. 
 
The air conditioner is provided with a power cord or a power terminal block.  Ensure that the power 
supplied is compatible with the air conditioner’s power requirements.  Properly connect the unit to a 
power circuit that meets the equipment requirements and provide a circuit protection device based on 
the Unit Specifications section of this manual.  See Appendix A for Wago power terminal block 
instructions. 

 

After mounting the air conditioner, replace/close the enclosure door and start air conditioner; test for 
air leaks to assure a proper closed air loop seal and run test the unit to assure proper operation after 
mounting.  If any cold air leaks are found, check for proper mounting and apply silicone-free Lexel seal 
if leaks persist.  Assur

e that the air conditioner’s condenser inlet air filter is installed properly and 

cleaned regularly. 

 
 
 

 

CAUTION 

If mounting the air conditioner to the enclosure door, confirm with the enclosure manufacturer that the 
door’s hinges will support the air conditioner’s added weight (see equipment specifications).  Ensure 
that when the door is fully open that the enclosure will not topple over due to the off-center load.
