Operation

Pressure Relief Procedure

WARNING

PRESSURIZED

EQUIPMENT HAZARD

The system pressure must be manually relieved to

prevent the system from starting or dispensing

accidentally. T

o reduce the risk of an injury from

accidental spray from the dispense valve, splash

ing fluid, or moving parts, follow the

Pressure

Relief Procedure

whenever you:



are instructed to relieve the pressure,



stop dispensing,



check or service any of the system equipment,



or install or clean the nozzle.

Shut of

f the air supply to the pump.

Close the bleed-type master air valve (D, required

in your system).

Hold a metal part of the dispensing valve (if used)

firmly to the side of a grounded metal pail, and

trigger the valve to relieve pressure.

Open the drain valve (H, required in your system),

having a container ready to catch the drainage.

Leave the drain valve open until you are ready to

spray again.

If you suspect that the spray nozzle or hose is com

pletely clogged, or that pressure has not been fully

relieved after following the steps above,

very slowly

loosen the hose end coupling and relieve pressure

gradually

, then loosen completely. Now clear the

nozzle or hose.

Packing Nut

WARNING

reduce the risk of serious injury whenever you

are instructed to relieve pressure, always follow the

Pressure Relief Procedure

above.

Check the tightness of the packing nut/wet-cup (U)

periodically

. The nut should be tight enough to prevent

leakage. T

orque the nut to 20–24 ft-lb (27–33 N.m); do

not overtighten or you may damage the packings.

Relieve pressure

before adjusting the nut. See Fig. 3.

If the pump is not immersed, fill the packing nut/wet-

cup 1/2 full with a compatible solvent. Keep the cup

filled at all times to help prevent the fluid you are

pumping from drying on the exposed displacement rod

and damaging the throat packings.

Flush the Pump Before First Use

The

pump is tested with lightweight oil, which is left in

to protect the pump parts. If the fluid you are using

may be contaminated by the oil, flush it out with a

compatible solvent. See
