Installation
Basic
See Figure 1.
1. Make sure the fluidizing drum (6) and cover (2) are securely clamped to the
body (3), and that all gaskets are undamaged and sealing properly.
2. Connect 10-mm flexible air tubing to the fitting labeled with the fitting on the
rear of the controller labeled with the hopper fluidizing icon ( ). Connect the
opposite end of the tubing to the fluidizing air connector (5).
WARNING: All electrically conductive equipment in the spray area must be
grounded. Ungrounded or poorly grounded equipment can store an electrostatic
charge which can give personnel a severe shock or arc and cause a fire or
explosion.
3. For stand-alone hoppers, connect the ground wire shipped with the hopper to
the ground stud (4). Connect the spring clip to a true earth ground.
For hoppers on a mobile powder system dolly, connect the dolly ground wire to
the ground stud (4).
4. Make sure the O-rings are installed correctly in the pump or adapter grooves.
Install the pump on or in the adapter with a slight twisting motion.
5. Connect the flexible vent hose shipped with the hopper to the vent hose
adapter (1). Secure the hose to the adapter with a hose clamp. Connect the
other end of the hose to the booth powder collector to prevent vented powder
from contaminating the room air.
Installing Additional Pumps
If you wish to install an additional pump, you must order a pump adapter and
pickup tube for it. Remove the plug from the cover and install the adapter, pickup
tube, and pump.

Operation
WARNING: Wear an approved respirator, protective clothing, and gloves when
handling powder. Avoid skin contact with powder coatings, or breathing powder
particles.
1. Fill the hopper half full of powder, to provide room for expansion as the powder
is fluidized. Do not overfill. Overfilling may prevent powder from being fully
fluidized, and affect coating performance.
2. Turn on the fluidizing air, and adjust the regulator until the powder is gently
“boiling.” The air mixed with the powder will cause it to increase in volume.
Fluidize the powder for five or ten minutes to make sure it is evenly fluidized
and no clumps are left before spraying.
Maintenance
Periodically, empty the hopper and clean the interior. Clean the fluidizing plate and
inspect it for signs of air contamination. If the plate is discolored and appears to be
contaminated, replace it. Check your air supply and correct any contamination
problems.
