Grounding

Tubing Lengths

The equipment must be grounded. Grounding reduces the risk of static and electric shock by providing an escape wire for the electrical current due to static build up or in the event of a short circuit.

1.Remove grounding screw on diaphragm pump (3) and tighten ring terminal on grounding cable (15) under ground screw.

The length of tubing (4, 16, 29) is determined by the hopper mounting configuration and heating choices. Reference the fluid schematic, from the configurations listed below, to find the tubing lengths.

Heating hoppers only. See FIG. 2 on page 9.

Heating hoses only. See FIG. 6 on page 13.

Heating hoppers and hoses. See FIG. 4 on page 11.

Cut tubing to length specified in fluid schematics.

1.Use tubing cutter to cut tubing (4) squarely to desired lengths.

NOTE: To ensure a leak-proof seal, apply PTFE tape on all npt threads.

2.Insert tubing through the back of the nut in each of the plastic fittings (7) until the tube stops. Tighten the nut hand tight, then tighten it to 1-1/2 to 2 turns with a wrench.
