Filter Installation
The following general information describes how to install the SM/SMBW 2000 Series™ Filter.
Note: Before installing this product, read and follow all warning notices and instructions starting on page ii.
General Filter Information
WARNING — THIS FILTER OPERATES UNDER HIGH PRESSURE. When any part of the circulating system,
(e.g., clamp, pump, filter, valve(s), etc.), is serviced, air can enter the system and become pressurized. Pressurized air can cause the lid to be blown off which can result in severe injury, death, or property damage. To avoid this potential hazard, follow these instructions:
1.Before repositioning valve(s) and before beginning the assembly, disassembly, or adjustment of the clamp or any other service of the circulating system: (A) Turn the pump OFF and shut OFF any automatic controls to ensure the system is NOT inadvertently started during the servicing;
(B) open the manual air relief valve; (C) wait until all pressure is relieved.
2.Whenever installing the filter clamp FOLLOW THE FILTER CLAMP INSTALLATION INSTRUCTIONS EXACTLY.
3.Once service on the circulating system is complete FOLLOW SYSTEM RESTART INSTRUCTIONS EXACTLY.
4.Maintain circulation system properly. Replace worn or damaged parts immediately, (e.g., clamp, pressure gauge, valve(s),
5.Be sure that the filter is properly mounted and positioned according to instructions provided.
1.New pools have a tremendous amount of debris due to dirt in the lines, plaster dust, etc. This debris will be removed by the filter and will require daily backwashing of the filter until it is removed. Check the pressure gauge daily and backwash the filter when the pressure increases 8 - 10 psi over the initial reading. It will require several backwashings before the pool is clean. Thereafter, the normal filter cycle will be several weeks in a properly designed system. The filter cycle is lengthened or shortened by contamination loads.
2.When installing backwash lines, it is recommended to install a vacuum breaker where the backwash line is over 40 feet long, or if the line discharges 10 feet or more lower than the water level of the pool. Operating at excessive vacuum levels can cause the tank to implode, which voids the warranty.
3.A check valve is recommended between the filter and heater to prevent hot water backup from damaging the filter internals.
4.The maximum operating pressure of the tank is 50 psi. Never operate the unit above this pressure or attach a pump to this filter that has a shut off pressure higher than 50 psi.
5.Never install a chemical feeder or ozonator upstream of the filter. Always locate downstream with a check valve between the feeder and the filter.
6.A positive shut off valve is not recommended downstream of the filter and/or heater. If the system is ever run with such a valve closed, the internal air vent becomes inoperative and an explosive situation could exist. Running the system with no flow can seriously damage the equipment.
