Installation
PUMP INSTALLATION
IMPORTANT: Pump is built to handle clear water only; it is not designed to handle water containing sand, silt or other abrasives.
1.Refer to Figures 6, 7, and 8 for typical installations.
Support pump and piping when assembling and when installed. Failure to do so may cause piping to break, pump to fail, motor bearing failures, etc.
2.If the pump is used as part of a per- manent installation, bolt to a rigid foundation.
!
Use only compo-
nents that are rated for maximum pressure pump can produce when used in boosting system or any other system. Do not exceed the total maximum pressure boost as listed per model in Performance Charts B.
PRESSURE BOOST SYSTEMS
1.On pressure boost systems, locate the pump so that there will always be a positive supply of water to the pump (See Figures 6, 7 and 8).
2.For service convenience, install a gate valve and union in the inlet and discharge line.
Do not use a globe valve or other restricting type of valve that will seriously restrict the pumps discharge capacity.

SAND AND SEDIMENT TRAP FILTER
3.Install a check valve as shown in Figure 6. Be sure check valve flow arrows point in the direction of water flow.
4.Whenever dirt, sand or debris is present in the supply water, install a strainer or filter on the inlet side of the pump (See Figure 7).
NOTE: For heavy amounts of sedi- ment, install a trap filter on the inlet
