OPERATOR INSTRUCTIONS
MAINTAINING NORMAL OPERATION UNDER USUAL CONDITIONS
5. Remove the pump to be replaced from the system.
6. Remove the threaded inlet and outlet fittings from the replacement pump.
7. Remove the threaded inlet and outlet fittings from the inoperable pump and install them on the
replacement pump.
8. Connect the system hoses and adaptor to the pump inlet and outlet.
WARNING
Electrical hazard. The TWPS operates on 416 volts AC. Pump skid electrical power cables
must be connected in a specific order. FIRST connect the pump skid power cable to its
pump skid junction box. NEXT, make sure the Main Breaker on the PDP is switched to
OFF. LAST, connect the pump skid power cable to its PDP power outlet. Failure to
observe this warning may result in serious injury or death from electrocution.
NOTE
Use the pump power cable appropriate for the function that the replacement pump is
serving. For example, if the P-7 distribution pump is being used in place of the P-2 pump
for raw water, use the power cable ordinarily used for the P-2 pump and plug the cable into
the P-2 terminal at the PDP. This ensures that the pump can be operated using the Raw
Water Pump button on the control panel.
If the heating blankets are used, the replacement pump/motor assembly must be removed
from its skid and installed on the skid for the pump being replaced. This is necessary
because only the junction box on the original pump skid has the proper number of
connectors for the heating blankets used at its location. For example, the P-7 pump skid
junction box does not have the number of heater connectors that the P-2 pump skid
junction box has. The P-8 pump does not have the same number of heater connectors as
the P-1 pump.
9. Connect the pump skid power cable to the junction box on the pump skid. Use the power cable
for the proper service.
10. Make sure the Main Breaker on the PDP is switched to OFF.
11. Connect the pump skid power cable to its PDP outlet.
12. Sanitize the raw water pump as follows if using it as a replacement for a distribution pump (see
Figure 10):
a. Install Adaptor A-08 on the pump discharge.
b. Disconnect and cap the distribution hoses from the adaptor.
c. Install the auxiliary hose and Valve V-522 assembly to one side of Adaptor A-08 and cap
the other side of the adaptor.
d. Open Valve V-522 and the valve on Adaptor A-07.
e. Switch the Main Circuit Breaker on the PDP to ON.
f. Start the pump and flush it with product water for 5 minutes.
g. Stop the pump.
h. Close the valve on Adaptor A-07.
i. Remove Adaptor A-08 from the pump discharge.
