Mounting Cooler

CAUTION:

(For operating weight, see Specifi ca tion Table.)
CAUTION:
Never plug in cooler until installation is complete
and unit has been tested for rigidity.
• Lift out all removable louvered sides.
• Screw chain hooks into win-
dow facing. Position the two
chain hooks above the neck of
the cooler a distance equal to
the width of the cooler apart
(A-Fig. 2). Hook one hanger
chain in each hook and then
one "S" hook in the other
end of each chain. NOTE:
Chain hooks supplied with this
mounting kit have wood screw
threads for wood walls. Con-
crete, brick walls or concrete
blocks require sufficiently
strong wing nuts or anchors
with mating hooks.

onto bottom of neck fl ange and position to the width of the window.
Cut the strips to fi t if necessary. These strips hold the window fi ll-
in panels (Fig. 3).

fl ange (E-Fig. 2) is snug against edge of sill (H-Fig. 2). With cooler
in position, hook the "S" hooks into the holes of the top pan near
the back of the cooler (B-Fig. 2).

nipple through the hole in the pan, with
the rubber washer between the pan
and the head of the drain nipple (Fig.

draw up tight against bottom of pan.
Insert the overfl ow pipe in the nipple
to retain water. The overfl ow pipe
may be removed to drain pan when
necessary. A garden hose may
be screwed onto the drain nipple
to drain water away from your
unit.

on a faucet as shown by fi gure 5.
Run 1/4 inch tubing from sillcock
valve to cooler. Place the nut and
ferrule on the tubing and tighten
the nut until water tight.
• Install fl oat valve. Install
valve in the provided hole in
the louvered side (Fig. 6) and
attach water supply line.
• Fill pan. Allow water to fi ll
to within 1" of top of pan
and ad just fl oat to maintain
this water level. This can be
accomplished by bending the
fl oat rod (Fig. 6).

Maintenance

WARNING:
Before doing any maintenance be sure power is
off and unit is unplugged. This is for your safety.

Spring Start-Up

• Change Pads. Aspen pads should be replaced once or twice a
season, depending upon the length of the season. At the beginning
and at mid season a clean pad is more absorbent and effi cient and
will deliver substantially more cool air.
