Grounding

Pump: grounded through Motor Electrical Connec-

tions on page 9.

Fluid lines: use only electrically conductive lines.

Fluid supply container: follow local codes and regula-

tions.

Accessories

Install the following required accessories in the order

shown in Typical Installation, page 7, using adapters

as necessary. These required accessories must be sup-

plied and installed by the customer before use.

•Fluid Filter (Y-Strainer) (included in K): with a 60

mesh (250 micron) stainless steel element to filter

particles from the fluid before it reaches the pump.

•Fluid Shutoff Valves (L): shuts off fluid flow.

•Pressure Relief Valve (D): overpressure protec-

tion.

Flush Before Using Equipment

The equipment was tested with lightweight oil, which is

left in the fluid passages to protect parts. To avoid con-

taminating your fluid with oil, flush the equipment with a

compatible solvent before using the equipment. See

Flush the Equipment, page 10.

The equipment must be grounded to reduce the risk

of static sparking and electric shock. Electric or static

sparking can cause fumes to ignite or explode.

Improper grounding can cause electric shock.

Grounding provides an escape wire for the electric

current.

Choosing an Installation

Location

1. Select a location that will adequately support the

weight of the pump, as well as all plumbing and

electrical connections.

2. Always mount the pump upright.

3. Mount the pump above the top rim of the contain-

ment tank, if used, to prevent submersion.

4. If you have a mounting configuration that requires

installation in a manner different than depicted in

FIG. 3, please contact your Graco distributor.

Fluid Connections

1. Remove and discard the caps on the Pump Inlet (H)

and Outlet (J). See FIG. 1 on page 5.

2. Connect a 1/4 npt(f) fluid line from the fluid source to

the Pump Inlet (H).

3. Install a Pressure Relief Valve (D) on the outlet side

of the pump. See FIG. 3 on page 7.

NOTE: A Pressure Relief Valve (D) is available from

Graco (see Kits and Accessories on page 18) and can

be connected back to the tank ordirectly to the inlet side

of the pump.

4. Set the Pressure Relief Valve (D) at or below the

maximum working pressure of the pump.

5. Connect a 1/4 npt(f) Outlet Line (F) from the Pump

Outlet (J) to the injection point.
