UNPACKING
The unit is shipped completely assembled and sitting on
a plastic pallet with a large cover box strapped over the
unit. Cut the straps and remove the box by lifting it over
the unit. Remove pallet and place cooler on a level
surface.
CONNECTING THE WATER AND
ELECTRICITY
WATER CONNECTION
NOTE: Unit must be in upright and level position.
After the unit has been thoroughly tested at the factory,
a special two-sided brass hose adapter is attached to
the water inlet on the side of the unit, which is below
the spray bar adjustment and drain valves. A standard
garden hose is attached to this brass hose adapter and
cinched down to preclude leaks. Visually verify that the
hose washer is in position and in good condition.
NOTE: Water supply inlet pressure should be
limited to 50 psi maximum.
Once the hose connection is made, water may be
turned on to the unit. Water should now be entering
through the float valve to fill the sump tank. To verify that
connections are secure, visually inspect connections for
leaks. Remove the cooling pads. See page 7 for details.
These coolers utilize a GFCI (Grounded Fault Circuit
Interrupter) or ELCI (Equipment Leakage Circuit
Interrupter) to help protect users against ground
electrical faults, which prevent some fire and electrical
shock hazards. These devices are intended to trip at
very low leakage currents.
• H-7127, H-8657, and H-9928 use a GFCI, which is built
into the power cord
LIQUID LEVEL INDICATOR / PUMP SHUTOFF
A liquid level indicator with integral shutoff gives a visual
indication of the water level in the evaporative cooler
and will shut off the pump once the water reaches a
certain threshold. When this occurs, a red light on the

SETUP
Once the sump tank is filled, the water flow should stop
and the inlet connections may now be visually checked
for leaks. Pay particular attention to the hose connection
into the float valve and the connections into the brass
inlet fitting.
All of these inspections have been performed at the
factory but shipping may have caused connections
to loosen.
The cooling pads may now be replaced. See page 7
for details.
ELECTRICAL CONNECTION
This unit utilizes a single power cord and control switches.
Before connecting the plug to an outlet, ensure that
there is no standing water where the cord may lie or the
operator is standing. The use of separate multiple outlet
devices are not recommended.
When making electrical connections, ensure that local
and national codes are adhered to. Use only with GFCI
protected receptacles.
Please refer to the barcode product label on the side of
the unit for specific electrical requirements.

plugged into an electrical outlet. The ELCI on H-7128
will not automatically reset when the evaporative
cooler is plugged into an electrical outlet; the reset
button located on the ELCI device must be pressed
each time the evaporative cooler is plugged in.
