Work area lighting
The work area is illuminated by two external fluorescent lamps which provide a minimum of 100 foot-
candles of light at the work surface.
Drain Pan
The drain pan is designed with 7/16” radius in all four bottom corners to facilitate cleaning and
disinfection. The work surface supports have been designed to be removable for easy cleaning and to
allow clear unobstructed access to the whole drain pan area during the cleaning procedure. Drainage is
provided by a 3/8” diameter stainless steel ball valve located at the bottom of the drain pan.
Air balance adjustments
Air balancing can be done by either of the following methods. However, it should be done only by a
technician with proper training and equipment (see “The Airflow Balance in
Section IV, On-Site
Checks and Maintenance
).
•
A speed controller adjusts for minor voltage differences and filter loading.
•
An adjustable external damper compensates for supply and intake imbalance due to pressure
resistance drop differences of supply and exhaust filters if they are changed at a later date.
Easy filter access
For convenience and ease of service, the downflow and exhaust HEPA filters are installed and removed
through the front of the cabinet without entry into the work area. This is particularly helpful if the
cabinet is connected to an exhaust duct. Filters should be replaced by qualified technicians only.
