1.7 Earth Ground
An Earth Ground stud is provided at the bottom right side on the enclosure back wall.
It is important to connect the ProFormer
™
system to an Earth Ground to bleed off
static electricity which may be generated while blasting. The Earth Ground may also
reduce the discomfort an operator may experience when static electricity is
discharged.
The Earth Ground conductors may be insulated or bare. Note that defects are more
easily detected during visual inspections of bare conductors.
The minimum wire size is dictated by mechanical strength rather than current
carrying capacity. Flexible conductors should be used when frequent connecting and
disconnecting of the Earth Ground is anticipated.
1.8 Installation Check
Step 1:
Check that all pipe and hose connections are tightly fastened and air tight.
Check that all safety pins are properly installed in all quick couplings.
Step 2:
Check that all electrical box covers are securely installed. Turn on the plant
compressed air supply to the system.
Step 3:
Check that the dust drum under the dust collector has been installed
properly. It must be sitting squarely on the dust drum platform and centered under
the cover. Set the dust collector pulse pressure regulator to 40 psi. Check that the
optional fan silencer is fully opened.
Step 4:
Turn the cabinet snap switch to the On position. The cabinet lights will
illuminate and the dust collector fan will start. Check that the fan is rotating in the
correct direction.
CAUTION
Disable and lock out power sources before performing service or maintenance
work. Do not look into the fan outlet to determine the correct motor rotation.
Check that the fan exhaust is clear of tools and free of debris before checking
fan rotation. To avoid personal injury, stay clear of the fan exhaust.
Step 5:
Set the blast air pressure regulator to the desired pressure. The blast
pressure may be set as low as 20 psi, but
do not exceed 125 psi.
Step 6:
Insert both hands into the cabinet gloves and firmly grasp the suction gun or
pressure nozzle. Step on the foot treadle. The blast should start. After a few seconds,
the airflow from the nozzle will stabilize. Blast will stop when the foot treadle is
released.
Step 7:
If applicable, press each dust collector pulse button once with the dust
collector on to insure pulse function.
The optional Photohelic control pulsing of the dust collector filters is automatic.
Adjust both red needles to below zero psi. The black needle must rise above both red
needles to activate the pulse. An increase in the gauge zero adjustment may be
required to test this function. After a successful test, the gauge setpoints should be
