Operation

NOTICE

Always close the ball valve (65) as soon as the inductor plate reaches the bottom of the drum, indi- cating the drum is empty. Allowing the pump to run without fluid will cause damage to the pump.

Installing a Drum

Refer to FIG. 9 for the following instructions.

1.Relieve the pressure, see Pressure Relief Proce- dure, page 5.

2.Close the ball valve (65). The handle will be at a 90° angle to the valve body.

3.Open the bleed-type master air valve (F).

4.Open the inductor plate vent by turning the knob (10) counter clockwise.

5.Pull open the snap-over valve (27) to raise the ele- vator.

FIG. 9

NOTE: To adjust the elevator speed, turn the restrictor valve screw (46) clockwise to decrease the speed or counter clockwise to increase the speed.

6.Center an opened 400 lb (181.4 kg) drum under the inductor plate so the drum bottom touches the ele- vator base (A).

7.Make the top of the fluid concave by scooping fluid from the center to the sides of the container.

8.Loosen the setscrews (73), holding pump mounting plates to the mounting bracket (C). Align the pump and inductor plate with the drum.

NOTE: Keep your fingers and hands away from the sides of the drum or inductor plate to avoid pinching them when raising and lowering the pump.

9.Push in the snap-over valve (27) to lower the pump while guiding the inductor plate into the drum.

10.Press down the pump and rock it back and forth to seat the inductor plate. This helps eliminate air trapped beneath the plate. Continue this action until fluid appears at the vent opening (D).

11.Be sure that the pump is aligned vertically and tighten the set screws (73).

12.Close the inductor plate vent by turning the knob (10) clockwise.

13.For Models 226013, 226018, and 244637 only:

a.Open the bleeder valve (94) at the pump outlet by turning the thumbscrew counter clockwise.

b.Open the ball valve (65) until all air trapped in the pump and under the plate are pumped through the valve.

c.Close the ball valve and the bleeder valve.

d.Regulate the pump speed with the ball valve handle.

14.All Models: Always use the lowest possible pump pressure necessary for good delivery. Higher pres- sures cause premature pump wear and usually do not produce better results.
