Mounting the Air Conditioner
Using the template supplied, determine where the air conditioner is to be mounted on the enclosure
roof and assure that all required cuts and holes will not interfere with, or damage, the enclosure or its
contents. Verify that the enclosure roof is capable of supporting the weight of the air conditioner.
Assure that there is a 3
” clearance between walls / obstructions and the air conditioner for the
condenser air supply and exhaust so that air flow is not restricted. Restricted condenser air flow will
affect the air conditioner’s performance. Position the air conditioner where the air can easily circulate
through the enclosure from the cold air supply outlet to the return air inlet.
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. Be cautious not to let
any cutting debris fall into the enclosure.
Using the lifting rings on the air conditioner housing, lift the unit and position it onto the enclosure by
inserting the tapered alignment pins on the bottom of the air conditioner into the matching holes in the
enclosure roof. Be careful not to damage the gasket on the bottom of the air conditioner by trapping
tools or objects between the air conditioner and the enclosure. From inside the enclosure install the
provided fasteners into the threaded holes in the bottom of the air conditioner. Ensure that these
fasteners are tight in order to create a proper seal between the air conditioner and the enclosure.
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 terminal block located in the return air inlet. 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 Phoenix Contact 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.
