Drain Connection The water pressure in the tank will increase as the tank fills with water. When the pressure in the tank reaches approximately 80 psi (552 kPa) the filter system shuts off. When water is drawn from the tank and the pressure drops to approximately 60 psi (414 kPa), the filter system will automatically turn on.
Start-Up Procedure 1. 2. 3. Check air pressure in the storage tank, Refer to Storage Tank Installation. (page 6) Close all water valves (5) in the system. (page 4) Open water supply valve at the connection to the main water feed and the inlet water valve at the unit. If manual bypass is installed it should be in the filter position. 4. Plug in transformer. 5. Plug bypass solenoid into the filter system. 6. Open the drain/sample valve. This will purge the air from the system.
