Initial System Start
Be sure that all selectors are in the “OFF” position before power is connected; this includes:
1. Main Power switch, marked “POWER”.
2. Neat Polymer Feed Pump switch, marked “POLY. PUMP”.
3. Water Inlet Solenoid Valve switch, marked “WATER SOL.”.
4. Polymer Tank Mixer switch, marked “MIXER”.
Initial Prime
The neat polymer pump must be primed before it can function within the system. This will require an
initial start of the pump. It is recommended that the system piping be filled with water before polymer
is introduced to the system.
1. Turn the Main Power switch to the “On” position.
2. Turn the Water Inlet Solenoid switch marked “WATER SOL.” to “HAND” position to initiate
water flow.
3. Once water starts to enter the Polymer Storage Tank, turn the Water Inlet Solenoid switch
marked “WATER SOL.” to “OFF” position to terminate water flow.
4. Open the Calibration Column Fill Valve; this aids in pump priming by providing a vent path to
the calibration column, bypassing the Back Pressure Valve.
5. Turn “POLY. PUMP” switch to “Hand” to start the Neat Polymer Pump.
6. Observe polymer flow through the clear braided tubing connecting the pump discharge to the
system piping; when present the pump is primed.
7. Turn “POLY. PUMP” switch to “OFF” to stop the Neat Polymer Pump.
8. Close the Calibration Column Fill Valve.
Selecting the manual operation mode marked “HAND” for any of the switches
will operate that device without regard for any of the safety features or alarm
modes that may be active. All safety requirements are the responsibility of the
operator while in manual “HAND” mode.
