Operation

Pressure Relief Procedure

1. Close the bleed-type master air valve (B) to shut off 

the air to the equipment.

2. Open outbound fluid valve to relieve fluid pressure 

from the equipment.
a.

For simple transfer applications,

 open either 

the fluid shutoff valve (K) or the fluid drain 

valve (J).

b.

For circulating applications, 

ensure that the 

fluid shutoff valve (K) is closed and open the fluid 

drain valve (J).

Flush Before Using Equipment

NOTE:

 The equipment was tested with water. If water 

could contaminate your fluid, flush the equipment with 

a compatible solvent before using the equipment.
Properly flush the equipment before use. Perform 

Start 

and Adjust the Equipment

, page 12, and 

Flushing 

and Storage

, page 13. 

Start and Adjust the Equipment

1. Confirm that the equipment is properly grounded. 

See 

Grounding

, page 7.

2. Check and tighten all fasteners, air connections, 

and fluid connections before operating the 

equipment. Replace worn or damaged parts as 

needed.

3. Connect a flexible, conductive fluid supply line (G) 

from the fluid to be pumped to the fluid inlet port (R).

4. Connect the flexible, conductive fluid outlet line (L) 

to the fluid outlet port (S) and route the line to the 

end container.

5. Close the fluid drain valve (J).
6. Turn the air regulator (C) to the lowest air pressure 

setting and open the bleed-type master air valve (B).

7. If the fluid outlet line (L) has a dispensing device, 

hold it open while continuing with the following step. 

8. To prime the pump, slowly increase air pressure 

with the air regulator (C) until pump starts to cycle. 

Do not exceed the maximum operating air pressure 

listed in the 

Technical Specifications

, page 32. 

Allow the pump to cycle slowly until all air is pushed 

out of the fluid lines and fluid exits the fluid outlet 

line (L).

Equipment Shutdown

At the end of each work shift, perform the 

Pressure 

Relief Procedure

, page 12.

Flush the equipment if necessary. See 

Flushing and 

Storage

, page 13.

Follow the Pressure Relief Procedure 

whenever you see this symbol.

This equipment stays pressurized until pressure is 

manually relieved. To help prevent serious injury from 

pressurized fluid, such as splashing fluid, follow the 

Pressure Relief Procedure

 when you stop 

dispensing and before cleaning, checking, or 

servicing the equipment.

NOTICE

Firmly tighten all fasteners and connections to avoid 

air or fluid leaks. To avoid equipment damage, do 

not over-torque the fasteners on the equipment. 

See 

Torque Sequence
