Mounting Using Chain Kit
An alternate installation method involves locating the unit in a suitable
window and using the included chain mounting kit to support the
weight of the cooler. As with platform or stand mounting, every
installation will be different. The exact requirements to mount and seal
a cooler against the weather will be best determined by the location
and at the time of the installation. Most installations will require
blocking of the unused portion of the window around the duct, or other
modifications to the window frame may be
necessary.
illustration (Fig. 2) for a typical installation. Remember, the framing
around the window must be strong enough to support the weight of the
cooler (approximately 150 pounds).
Chain Kit contains:
2 - Screw Hooks
2 - "S" Hooks
2 - Leg Leveling Bolts
2 - Rubber Pads
4 - 3/8" Square Nuts
4 - 3/8" Washers
2 - Hanger Straps
2 - #10-24 x 1/2" long Bolts
2 - #10-24 Nuts
2 - 5 ' long Chain
Install chain kit as follows:
Attach screw hooks to outside window frame approximately two
feet above top of cooler. Be sure hooks are inserted to full depth in
window framing for maximum strength.
Attach chain to each hook.
Attach hanging straps to top of rear corner support legs in the 3/16"
diameter holes using the #10-24 bolts and nuts provided. Install
"S" hooks in straps.
Place leg leveling bolts through 7/16" diameter holes in bottom of
front corner support legs. Use nut and washer on outside of
cabinet and install rubber pads on outside ends of leveling bolts.
Place second nut and washer on leveling bolts inside cabinet.
Position the cooler so that the duct rests on the window sill and the
grille flanges are inside the window frame, allowing the "Z" shaped
bracket, located under the grille, to rest on the window sill and butt
against inside of window sill flange. Connect "S" hooks and screw
hooks to chain links that bring the cooler closest to a level position.
Use leg leveling bolts to brace the cooler away from the wall.
Adjust bolts and chain to level cooler. NOTE: Cooler may need to
be re-leveled to compensate for the added weight of water.
Tighten nuts on leveling bolts inside cabinet.
Lower the window to rest on the top of the duct (vertically hung
windows) or slide window closed against side of duct (horizontal
slider windows). Block any remaining unused portion of the
window opening with a suitable blocking material (Plexiglas, solid
plastic sheet, solid wood panel, etc.). It will be necessary to seal
any joints around the duct to prevent entry of rain, dust/dirt,
insects, etc. Any good quality caulking or foam tape will work.
CAUTION:
Never operate unit with pad frame(s) and/or
air outlet grille removed. This will result in an overloaded
condition and may damage the motor.
Install Overflow Standpipe / Drain Line
Install overflow drain bushing in bottom of cooler as follows:
Slide rubber washer over drain bushing.
Push drain bushing through bottom of
cooler, assemble and tighten lock nut.
Screw plastic overflow standpipe into
See
the drain bushing and tighten snugly
(hand tight) to prevent leakage.
Connect a suitable drain line (copper /
PVC / garden hose) to drain bushing.
Never drain water onto a roof; mineral
build-up or damage to roof may occur.
NOTE: Drain water in accordance with local plumbing codes.
Install Bleed-off
To minimize mineral scale "build-
up"use the included bleed-off
assembly. Remove the cap from
the bleed-off tee; insert the black
tubing and route the tubing
through standpipe opening into
the drain line
.
To prevent
siphoning of the water, make sure
t at the bleed-off tee is above the
h
water level.
Connect Water Supply
CAUTION: All plumbing installations must comply with
local building and safety codes, and must be performed by
qualified personnel only.
NOTE: Coolers should not be connected to "soft" water systems. Soft
water will accelerate corrosion and decrease the effective life of pads
and cooler cabinet. Connect water line as follows:
A water supply valve should be installed at a convenient location,
to allow the water supply to be turned on and off for servicing or
winterizing. Minimum 1/4" diameter tubing should be used to
provide water to the cooler, larger tubing is recommended if the
distance from the valve to the cooler is greater than 100 feet, then
reduced to 1/4" at the unit.
Install float valve in the bracket provided.
Connect tubing from water supply to float valve. Place
compression nut and ferrule over end of tubing, insert tube into
float valve then tighten compression nut to secure.

OPERATION
Controls
The rocker control switches are used to select the operating mode of
the cooler. These switches control fan speed (High/Off/Low) and the
cooling (pump) operation (On/Off).
