Evaporative Cooling
Evaporative cooling uses the principle of evaporation to lower the air temperature. Hot, dry air is passed through wetted
filters and is converted to refreshingly cooled air. The HB30 makes the best use of the evaporative process by controlling
the flow of water, spreading the water evenly over the filters, and keeping a steady stream of cooled air entering your
home. It is exhausted out open windows or doors, carrying heat, smoke and odors along with it. The HB30 is 80% less
costly to operate than refrigerated air conditioners.
Cautions:
To prevent harm to yourself and others, and to avoid damage to your cooler, PLEASE follow these guidelines.
When Installing
When Operating
When Servicing
Make sure that unit is installed on a sound
structure that will support the full operating
weight of the cooler. See page 4.
Make sure that circuit cooler is plugged into is
equipped with a (slow blow) breaker large
enough to support the full amperage of the
cooler.
Always Unplug the cooler before attempting
service of any kind.
Before attempting to hang the cooler in the
window, remove the louver to reduce weight.
To reduce the risk of fire or electrical shock,
DO NOT use this fan with any Solid-state
speed control device.
Be sure to disconnect unit from power
source before servicing. If not, it can be
turned on from inside the house and start
unexpectedly.
Do Not connect power to cooler before
installation is complete.
This cooler is equipped with an
automatic
thermally protected motor. If it shuts off on its
own for any reason,
it can restart without
warning
.
If the motor shuts off because of thermal
overload, check into the problem
immediately. If allowed to continue,
permanent damage will occur.
MOUNTING
To install this cooler, the following tools are required:
•
Adjustable wrenches
•
Screwdrivers
•
Electric drill
•
3/16” drill bit
•
Level
1. Cut the Side Sealer Channels so that two of them will span the window when
butted together. Place two of the channels on the bottom duct flange as shown.
2. Place the Cooler in the center of the window with the bottom duct flange resting
against the sill.
3. Pull out the Spacer-Rods so as to allow the Rubber Feet to rest against the side of
the house. Tighten the Adjustment Screws.
4. Lower the window to rest on top of the duct behind the top duct flange.
5. Fasten a stop above the inside window sash to prevent the window from being
raised. Raising the window may cause the cooler to fall.
6. Adjust the Spacer-Rods to level the cooler. This will ensure proper water flow to the
pads.
7. Install the Chain Supports
(Not Included)
.
a. Drill pilot holes in the window frame, 3 feet above the top of the duct and the width
of the cooler apart. Install the Screw-Hooks in these pilot holes to the full depth of
the thread.
b. Hook one end of each Chain over each Screw-Hook.
c. Place S-Hooks in the holes at the top-rear of the cooler.
d. Place the opposite end of the S-Hooks in the free end of each Chain. Make sure
the chains are taut, but not so tight they pull the bottom of the cooler away from
the wall.
