IMPORTANT SAFETY INFORMATION This filter operates under high pressure. When any part of the circulating system (e.g., clamp, pump, filter, valves, etc.) is serviced, air can enter the system and become pressurized. Pressurized air can cause the lid or control valve to separate which may result in serious injury, death, or property damage. To avoid this potential hazard, follow these instructions.
FEATURES AND SPECIFICATIONS MULTI-PORT VALVE BACKWASH & RINSING VALVE PRESSURE GAUGE CONNECTING HOSE STAND PIPE PUMP & STRAINER BASKET LATERAL ASSEMBLY DRAIN CAP BACKWASH AND RINSING PORT: Waste port for backwashing and rinsing. MULTIPORT VALVE: Controls flow in and around the tank. PRESSURE GAUGE: Indicates PSI of the pump.
INSTALLATION SAND FILTRATION WORKING PRINCIPLE Incoming water from the piping system is automatically directed by the multi-port valve to the top of the filter bed. As the water is pumped through the filter sand, dirt and debris are trapped by the filter bed, and filtered out.

INSTALLATION INSTALLATION NOTES 1. Make sure the filter is operating under the working pressure and using a pressure control valve when the system is using a booster pump. 2. To aid in winterization and maintenance it is recommended that a separate gate valve be installed. 3.

INSTALLATION IMPORTANCE OF BACKWASHING The importance of backwashing cannot be overstated. Dense filter media can become “packed” without proper and frequent enough backwashing. Debris will remain trapped and create channelling within the filter bed. This will result in the filter bed exhausting early. Moreover, if debris is not flushed from the media grains, the filter bed will become dirtier and dirtier as time goes on until the filter operation fails.
