5. Handling Precautions
Exhaust blower
In order for the standard ventilator mentioned in “10. Specifications (P. 41)” to achieve the
standard discharge air quantity, the connecting duct must have the adequate diameter, be
up to 10 m in the straight length, and have up to 3 bends and an exhaust blower at the end.
If the condition is not satisfied, another ventilator must be selected.
(Straight section, bend and ventilator at the end are estimated to be our company’s standard
items.).
Ambient environment
● As fire-fighting measures, place water hose and/or foam extinguisher near the hood.
● Do not place any hazardous objects or obstacles near the hood.
Maintenance
● Periodically check the wires hoisting the windowpane. (Typical lifetime of wire is 3 years, but
it may be shortened depending on the used condition.)
● Interior and working surface of fume hood must be periodically cleaned with water.
● If the exhaust blower is corroded or whitened, replace it with new one.
● The exhaust blower must be turned off before check.
● Refer to “9. After-the-sale Service and Guarantee (P. 366)” for detailed information.

breaker in power distribution panel to which driving power is connected.

Modification of parts or wiring in the power distribution panel may result
in failure or fire.
