3. Close the drain plug pin (2SV only) and open the discharge valve. Install and torque
the vent plug to 15 lbs ft (20 N m). Close the drain plug pin.
4. Verify that the voltage on the pump matches what is indicated on the overload of the
motor starter.
5. Once the power source has been connected, check the rotation of the pump. Turn the
disconnect to the ON position. Jog each pump by momentarily turning the pump power
switch to the HAND position. A second person may be needed to see which way the
motor armature is turning just before it coasts to a stop. If the rotation is backwards,
switch any two of the three non-ground pump wires on the motor contactor inside the
panel.
6. After rotation has been verified, turn the switches on the controller to HAND. Allow
water flow to re-circulate through the loop and back in to the storage tank for a few
minutes. Water flow can be verified by observing the flow meter on the return header
of the storage tank. If this is a dual pump system, place pump #1 into HAND mode to
ensure that there is adequate flow through the system at the holding tank flow meter.
Once verified, repeat this for pump #2.
7. Place the system into auto mode to verify that the low level cut off switch operates
correctly. For a dual pump system, this will need to be done for each pump.
8. For the dual pump system only, the timer will need to be verified. This is accomplished
by setting the timer to its minimum value and ensuring that the system is alternating
between the pumps. See page 4 for details on adjusting the set-point.
9. The inlet and outlet valves are provided to allow for isolation of each pump if
maintenance is needed. During operation, leave all of the inlet and outlet valves open.
10. When performing a start-up of your distribution pump that is connected to a central
system storage tank, adjust the pressure relief valve on the storage tank header so that
the pressure gage at the pump is no higher than 75 PSI. Refer to the manual that was
provided with your storage tank system for proper adjustments. Pump curves have
been provided on pages 6 & 7.
5.0 DAILY MONITORING
AmeriWater recommends that the distribution pump assembly be checked at least once per
day to ensure that the pump is building pressure. To do this, read the pressure on the first
gage after the booster pump while water is flowing. This value should be recorded in the daily
logbook. During this check, listen to the distribution pump assembly to ensure that there is no
squealing. If any squealing is noted, this may indicate bearing wear and the need for a
service call.
