This is an operating manual for the SM/SMBW™ 2000 series filter, which mainly introduces the operation method, installation method, maintenance method and other information of the filter
This manual provides operating instructions for the Pentair SM/SMBW 2000 Series filter systems. It covers general information regarding safe operation under pressure and explains how diatomaceous earth (D.E.) functions as a filter aid to trap suspended impurities in pool water.
The document details installation requirements, including necessary clearances above the unit for different models and specific plumbing configurations such as check valves between filters and heaters. It also outlines step-by-step procedures for precoating the filter with D.E., backwashing the system to remove trapped debris, and routine maintenance checks.
| Maximum Operating Pressure | 50 psi |
|---|---|
| Recommended D.E. Particle Size | 34 microns |
One pound of D.E. is required per 10 square feet of filter surface area.
The filter should be cleaned when the pressure gauge reads between 8-10 psi higher than the original starting pressure.
The pump must be turned off, automatic controls shut off, and all pressure relieved from the system.
