V. Principles of Operation
The main component of the heat exchangers is counterflow aluminum element through
which heat transfer occurs.
Ambient blower draws ambient air from the bottom inlet through an aluminum mesh air
filter, through the element and exhaust it through a discharge grill.
Cabinet blower draws cabinet air from the top inlet through the element and exhaust it
through the bottom discharge into the cabinet.
VI. Specific Model Data
Mounting
Kooltronic Heat Exchangers have been engineered to be installed easily. To avoid damaging
your Heat Exchanger, please read the following information before installation:
1.
Remove and save the four screws holding the Mounting Template and Assembly Bracket
(M/TAB) to the unit. Remove the M/TAB.
2.
See Figure 1 for proper orientation.Place the M/TAB flush against the outside of the
cabinet to locate cutouts and mounting holes.
3.
NOTE: The top cutout for the warm air return does not have to match the full opening on the
M/TAB. You can locate your cutout anywhere within this opening. Locate your cutout close
to the top and not less than 4" high.
Make sure the cutouts don't interfere with
components inside your cabinet.
4.
Mount the M/TAB to the outside of the cabinet using all the mounting hardware supplied by
Kooltronic (
1/4
-20 screws/nuts/washers). Preferred positions: one in each corner and two
near center on each side. NOTE: Make sure the screws are inserted with heads on M/TAB
side. Tighten nuts securely.
5.
Route the power cord through the top cut out in your cabinet. Mount the unit to the M/TAB
by sliding the studs on each side panel into the slots on the M/TAB.
6.
Insert the remaining 10-32 screws and seal washers supplied by Kooltronic through the Air
Conditioner side panel and into the M/TAB. To avoid misalignment of parts, install and slight-
ly tighten all screws. Then secure all screws, but do not to overtighten.
