Warning
Do not alter the power distribution panel
Do not alter the contents (replace a part or wire) in the power distribution panel, or degraded function
or fire may take place. Also, do not touch the panel with wet hands, because electric shock may take
place due to the power source connected to this product.
Periodically check the wire for windowpane
Opening/closing mechanism of windowpane consists of balance weights which hoist the windowpane
with stainless steel wires. Though typical lifetime of wire is approximately 3 years, it may be broken
earlier than expected, depending on the used condition. Check the wires periodically.
Do not change filter alone
The filter must be replaced by multiple persons with each of them standing on his/her own steps (such
as stepladder). In this case, stepladders must be locked with stoppers and placed on a stable location.
This is a high place work, and therefore, may cause injury when he/she drops.
Do not obstruct the baffle plate.
The baffle plate has been designed in consideration of air flow distribution and discharge of heavy
gases. If the baffle plate is clogged or obstructed by an object, its baffle effect may reduce and the
discharged gas may be flowing in the reversed direction, which will have an adverse effect on human
bodies.
Do not perform any experiments when the exhaust blower stops
If the exhaust blower stops due to defective motor or power interruption, immediately stop the ongoing
experimental work, turn off the main power, and escape to a safe place with clean air supplied.
Do not adjust the damper
The damper has been properly adjusted by authorized person since the fume hood is installed. An
adjustment by unauthorized person may reduce the ventilation performance and cause an unbalance
between intake air and discharged air, which may have an adverse effect on human bodies.
Take care with gas leak (optional)
Care should be taken with gas leak.
Check the type of gas used (town gas or LPG) before use.
Always close the main valve and gas tap when the gas is not used.
The gas pipe/tube must be periodically checked and replaced.
Take care with electric shock at power plug outlet
An electric shock accident may take place if the power plug outlet on the front face of product is touched
by wet hand, or a conductive material is inserted into the outlet.
Take care with ground leakage of power outlet
The power outlet on the front face of this product must be connected to experimental equipment with
an appropriate resistance. If not, ground leakage or firing may be caused.
