ENGINEERING NOTES: Units,,,--( ) are metric 1. Operating weight 16,500 pounds 7484 (kg). 2. Maximum operating pressure 50 p.s.i. (3.45 bar). 3. Media required: 64 FTI (1.81 MI). 4. The filter system may be installed with the back and sides of the tank(s) against walls as operation and/or maintenance is performed at the front of the system 5. Influent, effluent and waste manifolds are reversible for right or left hand installations as desired. 6. Effluent rate of flow adjustment valve and backwash sight glass valves are not factory attached to the manifolds, allowing for installation options. 7. Provide a minimum clearance of 36" (.91 m) in front of the filter system. Refer to local code requirements. 8. Always provide shut-off valves in all pipe lines to and from the filter system when it is installed below the source water level. Failure to do so may cause flooding and/or injury. 9. It is recommended that a floor drain be installed in the filter room. 10. Flow meter - install the flow meter, allowing 60" (1.52m) of straight pipe upstream from the flow meter and 30"(.76m) downstream. 11 Seismic zone 4 filter tank leg design and anchoring hardware is provided. 12. DO NOT store corrosive chemicals such as chlorine, acid, etc., which will corrode equipment. 13. Pressure Amplification System: A constant 50 P.S.I. (3.45 bar) water pressure supply to the filter control mufti -port valve is required to operate the filter backwash valves. MODEL 2-0020-076 115 vac, 1 phase, 60 Hz. MODEL 2-0020-115 230 vac, 1 phase, 50 Hz. 14. All EPD filter systems are designed to backwash when a 15 P.S.I.D. (1.03 BarD) differential is indicated on the influent and effluent pressure gauges. 15. Electrical power supply to microprocessor (automatic filter systems only) A -115 vac, single phase, 60 Hz, 15 amp B - 230 vac, single phase, 50 Hz, 7.5 amp 16. Filter control microprocessor controlling features: A - Starts/stops flow: Controls pumps and/or automatic valves. B - Controls accessories during the filtering cycle such as chemical feed booster pumps, chemical feeders, etc. Power `ON' during filter cycle and power `OFF' during backwash cycle. C - Controls accessories during the backwash cycle such as water pressure supply, pressure amplification system, etc. Power `ON' during backwash cycle and power `OFF' during filter cycle. D - Two filter systems installed at the same facility: Both filter microprocessors may be wired together to prevent both filter systems from backwashing at the same time into the waste drainage system. E - A heater or boiler, when wired to the filter control microprocessor, will shut down 20 minutes prior to circulating pump shutting down and/or backwash. this mode allows for the cool down of the heater tubes, etc., to prevent scaling and/or thermal damage. (Refer to owners manual for wiring diagram). 17. All connections are American standard I.P.S./P.V.C. sockets or spigets.
