Setup

Grounding

WARNING

FIRE AND EXPLOSION HAZARD

Before operating the pump, ground the system as explained below. Also read the section FIRE OR EXPLOSION HAZARD on page 4.

Although water generally provides a natural electrical ground, the following equipment must be grounded if the cleaning chemical are volatile.

1.When cleaning in enclosed areas, such as storage tanks, locate the pump and air compressor outside the area and well away from it. Provide adequate ventilation. If the area you are cleaning has stored flammable materials. take appropriate precautions to avoid static sparking. Consult your local codes.

2.Pump: use a ground wire and clamp. See Fig. 1. Loosen the grounding lug locknut (W) and washer

(X). Insert one end of a 1.5 mm@ (12 ga) minimum ground wire (Y) into the slot in lug (Z) and tighten the locknut securely. Connect the other end of the wire to a true earth ground. Order Part No.

Fig. 1

3.Air and fluid hoses: use only electrically conductive hoses.

4.Air compressor: follow manufacturer???s recommen- dations.

5.Spray gun: ground through connection to a prop- erly grounded fluid hose and pump.

6.Fluid supply container: follow your local code.

7.Object being sprayed: follow your local code.

8.Solvent pails used when flushing: follow your local code. Use only metal pails, which are conductive, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts the grounding continu- ity.

9.To maintain grounding continuity when flushing or relieving pressure, hold a metal part of the spray gun firmly to the side of a grounded metal pail, then trigger the gun.

General Information

The typical setup shown in Figure 2 is only a guide to selecting and installing required and optional compo- nents. For assistance in designing a system to suit your needs, contact your Graco representative. Refer to Figure 2 for callouts in parentheses.

Setup

Connect Hoses and Mount Pump

Connect hoses and pump as follows:

NOTE: This pump is supplied with a bracket (D) which holds it to the side of a drum. If you want to install the pump on a wall, do not install the hanging bracket. Use Graco Wall Mounting Bracket 206???778 or equivalent for wall setup.

1.Screw the hose stud (A) of the suction hose (B) into the pump???s intake housing (C) using LoctiteR Pipe Sealant. Assemble the hanging bracket (D) to the pump with the screw, lockwasher, and nut (E) provided.

2.Remove the ball valve (17, see Parts) from Model 205???985. It is not used in this setup. Hang the pump on your empty cleaning solution drum.

NOTE: A pump runaway valve (F) may be installed near the pump air inlet. This valve senses when the pump is running too fast and shuts off the air to the pump.

3.Connect the air line lubricator (G) to the pump air inlet using pipe sealant. Install a pump air bleed valve (H) and air regulator and gauge (J) to the air line lubricator. Connect an air line filter (K) to the regulator. From the air line filter, install an air drain valve (L), bleed???type air valve (M), and connect to the air supply using electrical conductive air supply hose (N).

4.Close to the pump???s 1/2 npt(f) fluid outlet, install a tee (P) and a fluid drain valve (R). Then install a fluid hose (S) and Hydra???Clean gun (T). The hose and gun are supplied with Model 205???985, but must be purchased separately for Model 207???860.

CAUTION

Oils containing phosphate ester or chlorinated hydro- carbons are not compatible with the plastic bowl of the lubricator ??? be sure that oil used to lubricate the compressor is free of these additives.

Operation

WARNING

To avoid serious injury, including fluid injection and splashing in the eyes or on the skin, never point the gun at yourself or anyone else.

Before Using

See Fig. 2. Prepare cleaning solution as instructed, observing all safety precautions. Pre-mix powered cleaners in a separate bucket of hot water before adding to water in the supply drum.

WARNING

Take care not to get spray containing cleaning chemicals into your eyes, ears, or nose. If any spray does get on your skin or in your eyes, flush immediately and thoroughly with water. Seek immediate medical attention.

Open the bleed???type air valve (M), hold the spray valve trigger (T) open and slowly open the pump air bleed valve (H) until the pump is running slowly. After solution is coming from the spray nozzle, open the pump air bleed valve all the way and adjust the air line lubricator (G) to deliver about 1 drop per minute. Refer to the separate lubricator instruction manual.

Release the spray valve trigger and let the pump run.

NOTE: Protect surfaces that might be damaged by the cleaning solution and rinse off before the solution dries. For removing stubborn dirt, use a strong, heated solution.

Useful Hints

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the

Pressure Relief Procedure on page 8.

Hold the spray nozzle about 2 feet (0.6 m) from the surface you are cleaning and mist-wet it completely. Let it soak briefly, then use the spray to ???chisel??? the dirt off. Keep the nozzle at an angle, about 6 in. (150 mm) from the surface. If some dirt remains, wet the surface again. Let the object soak a little longer, then hold the nozzle as close as possible and spray to blast the dirt off.

After the dirt is removed, through rinse off the remain- ing solution with clear, cold water. When you are done cleaning, close the pump air bleed valve and relieve the pressure.

Shutdown and Care of Unit

CAUTION

To reduce the risk of damaging your pump. never allow the pump to run dry of fluid. Keep liquid in the container to prevent the pump from running away.

WARNING
