WARNING

HAZARDOUS FLUIDS

To reduce the risk of serious injury, splashing in the eyes or on the skin, and toxic fluid spills, never move or lift a

pump under pressure. If dropped, the fluid section could rupture. Always follow the Pressure Relief Procedure on page 9 before you move or lift the pump.

DThe pump is very heavy. If it must be moved, have two people lift the pump by grasping the outlet manifold (50). See the Parts Drawing on page 22.

Use a compatible thread sealant on all male threads. Tighten all connections firmly to avoid air or fluid leaks.

CAUTION

To avoid pump damage, do not overtighten the fittings to the pump.

Grounding

WARNING

ELECTRIC SHOCK HAZARD

This pump must be grounded. The steps for grounding may differ from the way you ground other pumps. Read and

carefully follow the grounding instructions below before you operate the pump.

To reduce the risk of static sparking, ground the pump and all other equipment used or located in the pumping area. Check your local electrical code for detailed grounding instructions for your area and type of equipment.

Ground all of this equipment:

DPump: Connect a ground wire and clamp as shown in Fig. 1. Loosen the grounding lug locknut (W) and washer (X). Insert one end of a 12 ga (1.5 mm@) minimum ground wire (Y) into the slot in the lug (Z), and tighten the locknut securely. Connect the clamp end of the ground wire to a true earth ground. To order a ground wire and clamp, order Part No. 222011.
