OPERATING INSTRUCTIONS - POWDERS & PARTICULATE
The following operating instructions are specific for containment of powders and particulate.
NOTE: Ensure that the INSTALLATION AND ASSEMBLY INSTRUCTION steps
have been completed.
A. To operate the enclosure:
1. Before use, ensure that you are not using an incompatible substance within the
enclosure. With a HEPA filter, use only powders in the enclosure. For other substances,
please call our office to verify compatibility before use (in this case, your filter may have
another model number). Direct Dial 919-255-3220 or 800-849-0472. Monday-Friday
8:00-5:00 PM EST.
2. Connect the supplied power cord to the unit and to the power outlet. Flip the switch on
the back of the unit above the power inlet module. This will activate the main power.
The screen on the controller should light up and display the time and the date. Allow the
enclosure to run for 5 minutes before beginning your application.
3. Perform any part of your process that involves powders or particulate inside your
enclosure.
B. When working within the enclosure, keep the front sash down and perform your
procedure in the center to rear of the enclosure.
C. If the low airflow alarm sounds and/or lights up, the pre-filter or HEPA filter may be
clogged.
D. When this happens refer to the "MAINTENANCE" section of this manual.
REMEMBER: Following the instructions assures better protection of the operator
and the environment, and extends the life of the enclosure and filter. Correct use
of the enclosure is the responsibility of the operator!
The alarms that are built into the system are maintenance related. They are designed to tell the
operator about conditions that may affect the operation of the enclosure and decrease its
performance.

reminder to change the filter before it becomes blocked.
