INSTALL THE DRIP PAN
1.
Two hose fittings were provided with the drip pan, a right angle and a straight one. Choose
one and install it on the drip pan. Be sure if you use the right angle fitting it is facing the
desired direction prior to installing the drip pan.
2.
There is one mounting hole in the drip pan, match this hole with the long mounting screw
protruding into the enclosure at the bottom of the AC unit. Push the drip pan onto this
screw.
3.
Using the 8-32 keps nut provided, attach the drip pan to the air conditioner.
4.
Attach the supplied PVC drain tube to the hose fitting on the drip pan. This tube should be
routed to the bottom of the enclosure and fed through a 3/8” hole to the outside.
APPLY POWER AND MOUNT THE THERMOSTAT
AAC-140 air conditioners are DC powered. They are designed to operate on 24 – 28 volts,
DC. Once the air conditioner is mounted, refer to the schematic supplied (see Appendix C, D) with
the unit for proper power wiring.
Amperage for 24 VDC unit is 4 amps
Amperage for 28 VDC unit is 5 amps
For other voltages you will receive a separate wiring diagram showing the correct method of
applying power.
If you purchased a Digital Temperature Controller with your AC unit, a separate wiring
diagram has been provided which will show the correct method of applying power to your
particular air conditioner.
The unit is supplied with a separate thermostat that should be mounted inside the enclosure
and wired to the unit per the supplied schematic. The thermostat can be mounted in any
orientation. The ideal location for mounting the thermostat is near the particular electronic item
you’d like to protect. Mounting the thermostat directly over a heat source may cause the AC unit
to run continually causing the enclosure temperature to drop below the thermostat set point.
Conversely, mounting the thermostat in the cool air stream from the AC unit may cause the AC
unit to shut down before the main part of the enclosure has been cooled to the thermostat set
point.
If you purchased a heating and cooling unit you will receive a second thermostat that should
be mounted following the same guidelines used in mounting the cooling thermostat above.
Upon applying power to the air conditioner the fan on the cold side (inside the enclosure) will
come on. The hot side fan (outside the enclosure) may also run depending on where the
thermostat is set. The cold side fan always runs to circulate air within your enclosure thereby
eliminating any “hot spots”. The hot side fans will only run when the air conditioner is cooling –
they are “pumping” the heat from the inside of your enclosure to the outside air.
