Water Supply System

A drain in the bottom allows you to drain the unit for cleaning and maintenance. A drain cap on the underside of the aluminum tray covers
the drain during operation. Make sure the cap is in place before you fill the bottom. The drain cap should be finger-tightened only.

The pump is attached to a bracket, which in turn is fixed to the blower housing. The bracket holds the pump in its proper position on top of
the foam filter and slightly above the bottom; allowing sufficient space for water to enter the pump suction.

The pump can be easily removed and replaced with the services of a qualified electrician.

A small plastic screen covers the pump inlet to prevent foreign matter from entering and damaging the pump impeller. The screen snaps in
place and can be easily removed for inspection or cleaning.

The pump sits on a foam filter; somewhat like a sponge. The filter traps dirt that could enter the water distribution system and build up on
the cooling pads; reducing their effectiveness. Dirt could also accumulate in the PVC pipes and plug up the spray holes.

The pump discharges through a fine, washable screen filter which decreases the contamination of the cooling pads and water system. The
discharge filter casing is a clear plastic so dirt buildup on the internal screen is easily visible. As dirt builds up, water flow to the cooling
pads is reduced and performance decreases. The clear filter housing is threaded and screws into the filter body for easy removal to
access the screen.

Note: 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 filter. From the filter, a "T" connector supplies two lines that run along the bottom and up
opposite frame corners to supply the PVC pipe with water. Each vinyl hose connects to two PVC pipes, which run horizontally along the
top of the frame above the cooling pads.

The PVC pipes have a series of holes that run the full length of the pipe. Each PVC pipe is covered with a plastic mesh sock which helps
break up the water as it leaves the spray holes. This gives a more even water distribution across the cooling pad and reduces splashing.
The holes direct the water inward at a 90° angle 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.

Note: 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.
