OPERATOR INSTRUCTIONS
INITIAL START-UP OR START-UP WITH THE SYSTEM FULLY DRAINED
OPERATION UNDER USUAL CONDITIONS
12. Once the P-1 and P-2 pumps are operating and the system is primed, adjust Raw Water Flow
Control Valve V-107 (see Figure 4 for valve location) about half open to provide a steady flow of
raw water into the MF Feed Tank. Depending on the elevation, if the valve is opened too much
initially, the pump could lose prime.
13. If the Cyclone Separator is in use, adjust the Cyclone Separator Flow Control Valve V-104 on
adaptor A-03 (see Figure 4 for valve location) to at least 5 gpm. A 5-gallon chemical bucket can
be used to provide measurement. Check the cyclone drain periodically to make sure there is
good flow coming out the cyclone drain.
CAUTION
Do not leave the P-1 pump running with V-107 closed without cracking open the Vent
Valve V-102. Failure to observe this caution will cause the pump to overheat and damage
the shaft seal.
14. If the MF Feed Tank reaches 3/4 full and you are not ready to continue with start-up, close Raw
Water Flow Control Valve V-107, stop motor driven raw water pump P-2 (if in use as the second
pump), crack open Vent Valve V-102 and leave the Diesel-Driven Raw Water Pump P-1 running
at idle.
15. Take a raw water sample from the MF Feed Tank and measure the TDS using the TDS meter
provided with the MC-TWPS or from the WQAS-P on the A-TWPS. Refer to Water Quality
TDS display indicates the measured TDS.
ESTABLISHING RAW WATER FLOW WITH ONLY THE MOTOR-DRIVEN RAW WATER PUMP
1. Set valve positions as follows (see Figure 6 for valve location):
a. Partially OPEN Raw Water Flow Control Valve V-107 on Adaptor A-05.
b. Fully OPEN Vent Valve V-102 on Adaptor A-02.
c. Check that the pump Drain Valve V-105 on Motor-Driven Pump P-2 is closed.
