Water Supply System

The water can be supplied continuously with an ordinary garden hose by attaching it to the supplied hose adapter
to the fill connection, or it can be filled manually.
With a continuous water supply connected, the float valve in the bottom rises and falls with the water level. A
linkage attaches the float to the shutoff valve in the fill connection. As the water level rises to normal operating level
(about 5" deep), the float valve shuts off the water supply. When the water level drops, the float valve opens to
maintain a normal operating level.
After unplugging the unit, the bottom can also be manually filled with a hose or bucket; if a hose connection is
impractical. Simply remove any of the pad sections and place the hose, or pour the water, directly into the bottom.
When you fill the bottom manually it can be filled to a higher level, but make sure someone monitors the filling
operation to avoid overfilling and flooding.
Water damage due to overfilling is not covered by the warranty.
When you run the unit and manually fill it, check the water level frequently so it does not run dry. Operating
the pump without water will damage it or reduce its service life. This is not covered by the warranty. The
cooling effect also stops if the pads are dry.
Pads must be replaced before operating unit.
A drain in the bottom allows you to drain the unit for cleaning and maintenance. A drain cap on the underside
covers the drain during operation. Make sure the cap is in place before filling.
The pump is attached to the fan housing. Plastic ties hold the pump in its proper
position.
The pump can be easily removed and replaced. A small plastic screen covers the
pump inlet to prevent foreign matter from entering and damaging the pump impeller.
A dirty water supply will quickly reduce the unit's performance and the unit
will require more frequent cleaning to maintain cooling effectiveness. Always
try to use a filtered, treated water supply.
A clear vinyl hose connects the pump to the valve. From the valve, a T connector supplies two lines that run along
the top of the pads and up to supply the PVC pipe with water. Each piece of vinyl hose connects to a PVC pipe,
which run horizontally along the top of the inlet above the cooling pads.
The PVC pipes have a series of holes that run the full length of the pipe. The holes direct the water inward at a 90°
angle against a deflector plate to continuously saturate the cooling pads from the top down. Excess water drains
back to the bottom through drainage holes in the bottom support channels which support the cooling pads.
Water cleanliness has a major effect on the cooler's performance. Use a clean water supply and consider a
water softener if your water is hard. Dissolved solids in hard water deposit on the cooling pad surfaces and
reduce the airflow through the unit and therefore the amount of evaporation.
