The condenser fan is controlled by the refrigerant high heat pressure and will turn on later
when the operating pressure builds up. This feature allows low ambient operation and
reduces current inrush at initial power on.
Run the air conditioner for 15 minutes; during this time the condenser fan will turn on after the
condenser coil warms up.
Note: Ambient Temperature must be at least 75°F.
Turn the unit off if the equipment makes any unexpected or hard mechanical noises or
vibrations and refer to the troubleshooting guide in this manual.
The supply cold air should be at least 10°F colder than the return air entering the unit. If it is
not, refer to the troubleshooting guide in this manual;
When you are satisfied that the unit is operating properly, turn unit off, disconnect the power
and mount the unit on the enclosure in accordance with the Mounting the Air Conditioner
section in this manual.
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 insure 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 Mount Flanges and from inside the enclosure use the fasteners
supplied to attach the air conditioner to the enclosure. Insure that these fasteners are tight in order to
prevent the unit from falling off the enclosure. These fasteners should be checked periodically to
insure 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.
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. Assure that the air conditioner’s condenser inlet air filter is installed properly and
cleaned regularly.
