Hazards or unsafe practices which could result in
minor personal injury, product or property
damage
IT IS THE RESPONSIBILITY OF THE EMPLOYER TO PROVIDE THIS INFORMATION TO THE
OPERATOR OF THE EQUIPMENT.
Important installation, operation or maintenance
information.
WARNING
Read the following warnings before using this equipment.
READ THE MANUAL. Before operating finishing equipment, read and
understand all safety, operation and maintenance information
provided in the operation manual.
AUTOMATIC EQUIPMENT. Automatic
equipment may start suddenly without
warning.
WEAR SAFETY GLASSES. Failure to wear safety glasses with side
shields could result in serious eye injury or blindness.
PROJECTILE HAZARD. You may be
injured by venting liquids or gases that
are released under pressure, or flying
debris.
DE-ENERGIZE, DE-PRESSURISE, DISCONNECT AND LOCK OUT ALL
POWER SOURCES DURING MAINTENANCE. Failure to de-energize,
disconnect and lock out all power supplies before performing
equipment maintenance could cause serious injury or death. KNOW WHERE AND HOW TO SHUT
OFF THE EQUIPMENT IN CASE OF AN
EMERGENCY.
NOISE LEVELS. The A-weighted sound level of pumping and spray
equipment may exceed 85 dB(A) depending on equipment settings.
Actual noise levels are available on request. It is recommended that
ear protection is worn at all times while equipment is in use.
PRESSURE RELIEF PROCEDURE.
Always follow the pressure relief
procedure in the equipment instruction
manual.
Hazards or unsafe practices which could result in
severe personal injury, death or substantial property
damage.
INSPECT THE EQUIPMENT DAILY. Inspect the equipment for worn or
broken parts on a daily basis. Do not operate the equipment if you
are uncertain about its condition.
OPERATOR TRAINING. All personnel
must be trained before operating
finishing equipment.
EQUIPMENT MISUSE HAZARD. Equipment misuse can cause the
equipment to rupture, malfunction or start unexpectedly and result in
serious injury. PACEMAKER WARNING. You are in the
presence of magnetic fields which may
interfere with the operation of certain
pacemakers.HIGH PRESSURE CONSIDERATION. High pressure can cause serious
injury. Relieve all pressure before servicing. Spray from the gun,
hose leaks or ruptured components can inject fluid into your body
and cause extremely serious injury.
KEEP EQUIPMENT GUARDS IN PLACE.
Do not operate the equipment if the
safety devices have been removed.
STATIC CHARGE. Fluid may develop a static charge that must be
dissipated through proper grounding of the equipment, objects to be
sprayed and alll other electrically conductive objects in the dispensing
area. Improper grounding or sparks can cause a hazardous condition
and result in fire, explosion or electric shock and other serious injury.
NEVER MODIFY THE EQUIPMENT. Do
not modify the equipment unless the
manufacturer provides written
approval.
PROP 65 WARNING. WARNING: This product contains chemicals
known to the state of California to cause cancer and birth defects or
other reproductive harm.

Prior To Use
Re-torque end cap nuts to 8 Nm prior to use.
Check periodically during use
This product should be flushed with a suitable compatible solvent prior to use.
Mount the pump securely and position the pump at a convenient height to allow for maintenance.
Attach flexible hoses to all connections.
Connect a regulated air supply to the air connection.
Set the pump speed to a slow cycle rate and prime the pump to remove any air before increasing pressure.
The pump must be earthed at all times. A resistance <1Ω when measuring with an ohm-meter at the earth point

Important Notes
1. For regulated units the pump air inlet pressure should be no more than 1.5 bar (21 psi) higher than the air
pressure to the fluid regulator.
Failure to do this will produce a greater pressure pulse than is intended and may reduce diaphragm or regulator
life.
2. End cap seals (DXK-5) MUST BE REPLACED every time an end cap is removed.
3. If end cap is removed fully clean and dry area around diaphragm before pump assembly.
4. Do not run the pump dry or allow it to 'race away', this may reduce the life of the diaphragms.
Failure to operate the pump correctly will invalidate the Warranty.
