California Residents WARNING: Cancer  www.P65Warnings.ca.gov The Pool Sentry&trade is used to maintain the water level of a pool, spa or pond automatically and unattended. When the Pool Sentry&trade is removed from the box, it is easily assembled by snapping together two parts and threading in the valve assembly. This requires no tools. It comes with a heavy plastic, zip-lock bag that is filled with rocks or pea gravel and used as a weight to hold the unit on the deck. The bag is placed inside the cavity by removing the top cover. It is then attached to a garden hose and the water is turned on. Shipping the Pool Sentry&trade with the bag empty reduces the weight of the package. The water stays on at all times when the Pool Sentry&trade is in the pool. As the float drops the water turns on. When the float reached its highest point, the water shuts off. It works very similarly to the float valve in a toilet tank. The customer can adjust the float to any desired level (usually a point halfway on the tile line or skimmer)Features:Protects pump against burnout Maintains water level while on vacation Use for rental or vacant homes Fills pool after acid wash No tools required&ndash simply attach hose Controls level in leaking pools, ponds or spas Unattached operation Completely portable
