Pressure Relief Procedure

PRESSURIZED EQUIPMENT HAZARD
The equipment stays pressurized until pressure is
manually relieved. To reduce the risk of serious injury
from pressurized fluid, accidental spray from the gun or
splashing fluid, follow this procedure whenever you:
• Are instructed to relieve pressure,
• Stop pumping,
• Check, clean or service any system equipment,
• Install or clean fluid nozzles.
1. Shut off the air to the pump.
2. Open the dispensing valve, if used.
3. Open the fluid drain valve to relieve all fluid
pressure, having a container ready to catch the
drainage.

Flush the Pump Before First Use

The pump was tested in water. If water could
contaminate the fluid you are pumping, flush the pump
thoroughly with a compatible solvent. Follow the steps
under Starting and Adjusting the Pump.

Starting and Adjusting the Pump

TOXIC FLUID HAZARD
Hazardous fluid or toxic fumes can cause
serious injury or death if splashed in the
eyes or on the skin, inhaled, or
swallowed. Do not lift a pump under pressure. If
dropped, the fluid section may rupture. Always fol-
low the Pressure Relief Procedure above before
lifting the pump.
1. Be sure the pump is properly grounded. Refer to
Grounding on page 7.
2. Check all fittings to be sure they are tight. Be sure to
use a compatible liquid thread sealant on all male
threads. Tighten the fluid inlet and outlet fittings
securely.

3. Place the suction tube (if used) in the fluid to be
pumped.
NOTE: If the fluid inlet pressure to the pump is more
than 25% of the outlet working pressure, the ball check
valves will not close fast enough, resulting in inefficient
pump operation.
4. Place the end of the fluid hose (L) into an
appropriate container.
5. Close the fluid drain valve (J). See Fig. 2.
6. With the pump air regulator (C) closed, open all
bleed-type master air valves (B, E).
7. If the fluid hose has a dispensing device, hold it
open while continuing with the following step.
8. Slowly open the air regulator (C) until the pump
starts to cycle. Allow the pump to cycle slowly until
all air is pushed out of the lines and the pump is
primed.
If you are flushing, run the pump long enough to
thoroughly clean the pump and hoses. Close the air
regulator. Remove the suction tube from the solvent
and place it in the fluid to be pumped.
