Dryer External Connections
Once assembled, installation requires connection of: pneumatic air line, electrical, intake and
output material lines.
Compressed Air Connection
Connect an air supply to the air regulator’s IN port using a female
1/4” NPT pipe fitting.
An operating air pressure of 80 psi (5.5 bar) while the
vacuum generator is running is required for proper operation
of the Dryer. Setting the air pressure to 85 psi while the
machine is idle will usually attain the desired 80 psi while the
vacuum generator is running.
If your air supply has oil in it, add an oil separator (coalescing
filter). Oil in the air will combine with dust drawn from the
Vacuum Chamber forming a paste inside the vacuum generator.
It will stop working and require cleaning.
Observe the air pressure gauge to be sure the pressure
maintains 80 psi (5.5 bar) while the vacuum generator is running
as you check and adjust the regulator. If pressure drops below
80 psi, adjust the regulator. If the pressure cannot be maintained
at 80 psi (5.5 bar) while the vacuum generator is running, then
the air supply line is not adequate.
Do not supply Dryer with a lubricated air supply.
Damage to Dryer may result. Use only a clean,
dry, oil-free air supply.
Pinch Hazard - Keep fingers clear of seal
deck, the mating surface above the Vacuum
Chamber seal.
When air pressure is turned on and the
Vacuum Chamber Lift Switch is flipped up, air
cylinders lift the Vacuum Chamber off of the
slider rails and up to the seal deck closing the
gap between the top of the Vacuum Chamber
and the seal deck.

Confirm Correct 3-Phase Electrical Connection
THREE PHASE Unit - CONFIRM proper 3-Phase power connection prior to
loading material. Failure to confirm proper 3-phase connection can result in
reversed blower rotation and damage to blower if the blower sucks in material
from heating hopper rather than blow heated air into heating hopper.
To confirm proper 3-phase connection following these instructions:
Turn power on using main power switch.
There are two methods to confirm proper
3-phase connection:
Incorrect 3-phase connection will result in
reversed blower rotation. Both methods
for checking correct 3-phase connection
involve testing the blower rotation.
Method one requires the disconnecting the
2-inch hot air hose from the heating hopper
and manually turning on the blower. The
air from the blower should blow out of the
2-inch hose. Air should not suck into the
hose. If air does not blow out and sucks in,
the 3-phase connection is NOT correct.
Method two requires the removal of the left
side panel to view the blower and confirm
blower rotation on power up. Rotation
must be clockwise as indicated by the red
arrow.

BD®- Vacuum Dryer®
Startup and Operation
This section will help you understand what the dryer is doing during operation from a cold start.
There are 3 concurrent operations. Heating, Vacuum and, Retention. Cold startup begins with
Preheat. Preheat only occurs before the first cycle of the dryer’s initial startup, otherwise each
cycle begins with material heating. The vacuum operation pulls and holds a vacuum on the
material for at least the Vacuum Time Set-point (or longer if material remains in the Retention
Hopper). The Retention operation holds the dried material in the Retention Hopper, blanketing
the material with hot, dry air, until the material is conveyed away.
Important: Inspect the VBD, verify that machine is clear of all material from heating hopper,
Vacuum Chamber and Retention Hopper. To facilitate a Clean Out, use the Clean Out
function accessible from the home screen.
Startup and Operation Instructions
1. ENSURE HATCH IS CLOSED. There is a hatch located on the upper
Heating Hopper. Ensure all 3 latches are closed. Also be sure the
removable Lower Retention Hopper is in place.
2. Load material into the Upper Heating Hopper. Wait for the Heating
Hopper to fill with material before starting the Dryer.
3. Turn on Main Power by rotating the 25 AMP Main Disconnect Handle
to the Red ON position. This powers up the VBD-150 Dryer.
On initial power up of the VBD, the Control Panel powers ON
automatically. If the main power is ON but the Control Panel is OFF,
press and hold the Red Power Button located on the Control Panel for
2 seconds. (Note: The VBD’s Control Panel can be powered OFF
without powering down the Main Power by pressing and holding the
Red Power button for 4 seconds).
4. After material has been loaded into the Heating Hopper,
select Run Dryer and press the ENTER button.
