Issue Date: January 2009
Set-Up and Test
1.
Place the DirectFlo within reach of the electrical outlet and the air source. Refer
to “The Proper Work Area” discussed at the beginning of this chapter.
CAUTION:
The DF1400 weighs approximately 65 to 80 pounds
(depending on model). Use appropriate caution
while lifting.
2.
Remove the tank cover by loosening (do not remove) the four nuts with the 9/16"
wrench provided in the accessory kit. Let the cover bolts swing down and lift off
the tank cover (see figure 2-4).
3.
Grasp the powder basket by the lip and lift straight up. Avoid lifting the powder
basket near the slot, since this is the weakest point in the lip. The slot is for
pouring. It is not a handle.
4.
Carefully clean out any foreign material from both the basket and the tank.
Check the tank orifice to make sure it is clear; remove it if necessary (see Fig. 3-
1). Insert the basket back into the tank by pushing down with a slight twist, to
seat the O-ring. Clean off the tank cover and check to make sure that the O-
rings are not damaged and that the sealing surface is clean.
5.
Wipe off the top surface of the tank and replace the tank cover. Be sure that the
tank cover is properly oriented on the tank, with the vent holes at the front and
rear. Swing the bolts up into the slots in the cover and tighten the nuts firmly, but
not too tight.
6.
Remove the pr
otective red cap from the end of the PowderGate’s output
connector and connect the Abrasive Hose to the connector. The Abrasive hose
is tethered to the Direct
Flo’s back panel by the hose’s ground wire. Leave this
ground wire attached to the panel.
7.
Connect the DirectFlo to a dry air supply using a
1/4” Industrial Shape Quick-
Disconnect Coupling Socket
(customer supplied).
Example couplings: Foster 3 Series SG1513 or McMaster Carr 6536K38
The blasters air input plug is located on the back of the blaster(see Figure. 2.3).
8.
Set the air pressure upstream of the DirectFlo DF1400 to at least 80 PSIG but
not more than 140 PSIG.
CAUTION:
Inlet pressures above 140 psig may damage the
DirectFlo DF1400. The DirectFlo DF1400 has an internal
pressure relief valve, however, Comco recommends that
the system inlet line have a relief valve also.
