Maximum Visibility
Visibility is maximized on all units with at least 270 degree visibility from
both sides and the front pivoting sash. Some 3' and 4' models have 360
degree visibility which is especially useful in classroom demonstrations. See
Chapter 2: Prerequisites
for model differences and model numbers.
Simple Electrical Connection
All 100-115V Paramounts are pre-wired with circuit breaker and IEC
electrical power cord that is simply plugged into a nearby electrical
receptacle. 230V units are shipped without a plug. Install the appropriate
plug for your electrical specification per local codes. All the impeller, light,
and airflow monitor wiring is internal and no electrical wiring connections
are needed. Paramounts are available in two voltages, 100-115V, 50/60 Hz
and 230V, 50/60 Hz.
See Chapter 2: Prerequisites
for model numbers.
Safety Precautions
1.
Although the enclosure has been engineered to maintain optimum
operator safety, caution should always be used while working. Prior
to using the enclosure, check to make sure that the exhaust blower is
operating and that air is entering the enclosure at its specified face
velocity. The airflow monitor will alert the user to a problem with
airflow.
2.
Use good housekeeping in the enclosure at all times. Clean up spills
immediately. Periodically clean enclosure interior.
3.
Do not overload the work surface with apparatus or work material.
The safe operation of the enclosure is based upon having proper
airflow through the structure. Do not place large objects directly on
the work surface. Instead, elevate the object 3/4" on blocks to allow a
flow of air under the object and into the rear baffle exhaust slots.
Ensure blocks are level and secured in place.
4.
Blocking large portions of the rear baffle will change the airflow
pattern in the enclosure causing turbulence. (Do not store containers
or supplies against the rear baffle, as this will affect airflow).
5.
Always work with your hands as far back into the enclosure as
possible. Keep all powders, chemicals and apparatus inside the lower
air foil of the enclosure.
6.
Do not work in this enclosure without the blower running and a face
velocity of 60-100 fpm.
7.
Perchloric acid use in this enclosure is prohibited.
8.
High-level radioisotope materials are prohibited in this enclosure.
Consult your Safety Officer.
