OPERATION

Priming the Pump

NOTICE: To properly prime the pump, install a pipe tee in

the discharge piping (see Figure 1, Page 4).

To prevent damage to internal-parts, do not start motor until pump has been filled with water.

To prime pump:

1. Remove priming plug (Purchase separately; Figure 1, Page 4).

2.Fill pump with water.

3.Replace priming plug, using Teflon tape or Plasto-Joint Stik 2 on plug threads; tighten plug.

4.Start the pump. Water should be pumped in 1-2 minutes. If not, repeat steps 1, 2 and 3.

On shallow depths to water (10 feet or less), the pump

will probably prime the first time after the following steps 1 through 4 above.

From 10 to 20 foot depths, you might have to shut off the pump and repeat steps 1, 2 and 3 several times.

5. If, after priming pump several times, no water is

pumped, check the following:

A. Be sure suction pipe is in the water.

B. Be sure suction pipe does not leak.

C. Be sure that pump is not trying to lift water too high (see "Piping in the Well", Page 4).

D. As long as foot valve and check valve function cor- rectly and suction pipe does not develop leaks, pump

should not need repriming in normal service.
