Set-Up and Test
(cont’d)
9.
Make sure that the Power switch located on the front of the panel is in the OFF
position.
10.
Find the power cord in the accessory kit and plug it into the 3-prong male
connection located on the back of the unit (see Figure 2-3).
CAUTION:
The DF1400 can be manufactured for either 115VAC or
230VAC. Check the voltage on the nameplate located
on the back panel to see which voltage is correct for your
machine.
11.
Plug the 3-prong male end of the power cord into the appropriate facility outlet.
12.
Find the footswitch in the accessory kit and plug it into the 4-pin connector
located at the back of the unit (see Figure 2-3). Place the footswitch on the floor
in any convenient position for the operator.
13.
Insert the end of the hose connected to the “Tank Vent” on the rear of the
machine into one of the tube grips located in the back of the workstation. Push
the tubing through the grip 1 to 2 inches, and hand tighten
the grip’s nut to
secure the tubing. When connecting the DirectFlo to an automated system, the
vent tube grips can be found on, or near the dust collection outlet of the blast
chamber.
CAUTION:
The air that comes out of the vent hose will contain
abrasive. Place the free end of the vent hose into the
WorkStation or the dust collector.
Always
secure the
free end of the hose.
14.
When routing t
he abrasive hose into the workstation or a system’s blast chamber
avoid tight hose bends. Use as large bend radii as feasible to reduce internal
hose wear. Abrasive hoses wear quickest at their bends and small bend radii
accelerates the wear.
15.
Turn t
he Power switch to “ON”. The switch should illuminate and the system
should start to pressurize with an audible hissing sound (approximately 5
seconds). The PowderGate will close and the pressure gage on the front of the
unit should indicate pressure in the unit. Listen for obvious leaks.
CAUTION:
Do not lean over the abrasive tank while the system is
pressurizing.
