Section 1. Pump Safety Instructions.
When installing and using this electrical equipment, basic safety precautions should always be followed, including the following:
1. READ AND FOLLOW ALL INSTRUCTIONS.
2. WARNING - To reduce the risk of injury, do not permit children to use this product unless they are closely supervised at
all times.
3. WARNING - Risk of Electric Shock. Connect only to a grounding type receptacle protected by a ground-fault circuit-
interrupter (GFCI). Contact a qualified electrician if you cannot verify that the receptacle is protected by a GFCI.
4. Do not bury cord. Locate cord to minimize abuse from lawn mowers, hedge trimmers, and other equipment.
5. WARNING - To reduce the risk of electric shock, replace damaged cord immediately.
6. WARNING - To reduce the risk of electric shock, do not use extension cord to connect unit to electric supply; provide a
properly located outlet.
7. CAUTION - For continued protection against possible electric shock, this unit is to be mounted to the base in accordance
with the installation instructions.
8. CAUTION - If this pump is equipped with a 25 ft. cord, it is for use with storable pools only. Do not use with permanently
installed pools. A storable pool is constructed so that it may be readily disassembled for storage and reassembled to its
original integrity. A permanently installed pool is constructed in or on the ground or in a building such that it cannot be
readily disassembled for storage.
9. SAVE THESE INSTRUCTIONS.
This filter operates under pressure. With the valve clamped properly and operated without air in the system, this filter
will operate in a safe manner. Air entering the filter and the valve not clamped correctly can cause the valve to be
blown off, which could cause severe personal injury and/or property damage.
WARNING
WARNING
To reduce the risk of electric shock, do not use an extension cord. Only connect to a GFCI protected receptacle. Failure to
do so could result in an electrical shock to pool users, installers, or others which can result in serious personal injury or
death.
Section II. How Your Filter Works.
Your high rate sand filter is designed to produce clear, sparkling water and operate for years with a minimum of maintenance when
installed, operated and maintained in accordance with these instructions.
Your filter uses special filter sand to remove dirt particles from the water. Dirt is collected in the filter by the sand bed as water
flows through the filter. Water enters the filter through the valve on top of the filter and is distributed evenly downward across the
sand bed. The dirt is removed by the sand and the clean water flows through the piping (laterals) at the bottom of the filter, up
through the center pipe, back to the valve on top of the filter, where the clean water is returned to the pool through the piping or
hoses.
After a period of time, dirt will accumulate in the filter causing a resistance to the flow of water through the filter. This resistance
results in a diminished flow of water and a rise in the pressure of the filter. Eventually the filter sand will have removed so much
dirt and the filter pressure risen to such a point that it will be necessary to clean (backwash) your filter.
By setting the valve on top of the filter to the backwash position, the flow of water is automatically reversed through the filter so
that the flow of water is directed to the bottom of the filter, up through the sand bed flushing, the dirt and debris out through the
waste line. Once the backwash procedure is complete, the valve is manually returned to its filter position to resume normal filtra-
tion.
