installed to allow the disconnect to be locked in the OFF position. Open and lock the
disconnect installed in the control enclosure. It is advisable to remove the disconnect
fuses and carry them with you.
3-2 Installation Location Considerations
Your hot air dryer was designed to be mounted near the processing machine and connected to
the drying hopper with the high temperature, flexible hose provided with the unit.
Note: Make sure to allow enough dryer hose to compensate for any movement of the
drying hopper.
Hose Connection
a. Remove the shipping cap from the air heater can outlet.
b. Connect one end of the dryer hose to the outlet with a hose clamp.
c. Attach the other end of the hose to the inlet of the drying hipper and secure with a hose
clamp.
3-3 Assembling the Air Diffuser/Air Trap
On existing machine hoppers, it may be possible to install the optional air diffuser assembly
if the machine hopper is the proper size. The hopper must be round and have sufficient
capacity for the proper material residence time. Consult factory for drying times required on
other materials.
1. Position the air diffuser so that it rests on the support arms of the machine hopper.
2. Adjust the support arms to allow two to four (2 to 4) inches (51 mm to 102 mm) from
the diffuser screen to the hopper wall and keep the space constant around the air
diffuser.
3. Cut the high-temperature flexible hose to suit the hopper depth. Centrally locate the
hose over the hopper discharge throat. Make sure that the screen diffuser does not
get tilted out of position. Secure the hose with the clamps provided.
