VII. Specific Model Data

Mounting

Kooltronic Special Purpose Air Conditioners K_NA_C4P32 have been engineered to be
installed easily. These units use fully gasketed flanges to insure a seal between the air
conditioner and the cabinet. This seal is necessary to maintain the integrity of the closed loop
system as well as the NEMA 4 rating.

Prior to mounting, refer to page 8 for general arrangement drawings showing dimensions and
locations of mounting holes and cutouts.  Prior to cutting or drilling, make sure that cutouts
and mounting holes do not interfere with components inside of the cabinet.  To avoid
damaging your Air Conditioner, please read the following information before installation.

1. Remove and discard (2) nuts and washers holding the Mounting Template and

Assembly Bracket (M/TAB) to the Air Conditioner.  Remove M/TAB.

2. See page 8 for proper orientation.  Place the M/TAB flush against the outside of the

cabinet to locate cutouts and M/TAB mounting holes.  

The minimum distance

between lower end of the M/TAB to the ground is 11” for all P32 units.

3. The cutout for warm air return does not have to match the full 8” x 11

1/

2

” opening on

the M/TAB.  You can locate your cutout anywhere within this opening, making the
return air cutout from the cabinet as large as possible.  Make the cold air supply cutout
the same size as on the M/TAB.

4. Mount the M/TAB to the outside of the cabinet using all the 1/4-20 x 1/2” bolts,

washers and nuts supplied by Kooltronic.

5. Route the power cord through the return air cutout of the cabinet.  Mount the air conditioner

on the M/TAB by sliding the (4) mounting studs, installed on the air conditioner side
panels, into the (4) inclined slots of the M/TAB.

6. Carefully mark all mounting holes from the flanges of the air conditioner to the cabinet

wall.  All holes in the air conditioner flange must be used to maintain the NEMA 4 rating.

7. Remove the air conditioner from the M/TAB and drill .218” dia. mounting holes in the

cabinet.  Do not attempt to drill mounting holes in the enclosure without first removing
the air conditioner.  Drilling through the sealing gasket may damage it and remove the
NEMA 4 rating.

8. Repeat actions, described in item “5” above.

9. Insert the stainless steel screws with seal washers supplied through holes in the

mounting flanges and the cabinet wall.  Install washers and nuts on each screw from
inside of the cabinet and hand tighten.  Tighten all nuts to a torque of 20 in.-lbs. going
in a clockwise rotation starting from the top left corner.  Retighten to a final torque of
34-40 in.-lbs. in the same rotation as previously used.  The torque should be
rechecked after the gasket has been allowed to set for 1 hr. and again after the air
conditioner has  been run for 24 hrs.  Check the flange gasket compression, after
tightening all nuts - the gasket should be compressed by approximately 1/2 the
gasket thickness (1/8”).

10. After making sure that the source voltage and frequency are the same as shown on

the unit nameplate, connect the air conditioner’s power cord to the power supply.

CAUTION

If the Air Conditioner is mounted to the cabinet door you must be sure

that the door hinges will support the additional weight of the Air

Conditioner. Also be certain that when the door is opened fully, the

cabinet does not become unbalanced. The actual weight of the unit can

be found in the performance specifications.
