The condenser fan is controlled by the refrigerant 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.
Note: The CS011 series is constructed with two condenser coils so that it
is permissible to provide less than a
3” clearance for the supply air to one of the coils without affecting
performance.
Mount the air conditioner high on the enclosure in order to cool the hot air at 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 flange and from inside the enclosure use the fasteners
supplied to attach the air conditioner to the enclosure. Ensure that these fasteners are tight in order to
prevent the unit from falling off 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. 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 connector
instructions.
After mounting the air conditioner, replace/close the enclosure door and start air conditioner; test for
air leaks to assure a proper closed loop air 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.
