Operation Method
①
Turn all breakers in the distribution panel to ON.
②
The exhaust blower and fluorescent light can be controlled with keys on the control panel.
When the exhaust blower stop key is depressed at the end of operation of this product,
the delay timer activates to continue the operation of exhaust for the predetermined time
period (factory setting: 10 min; 0, 5, 10 or 30 min is selectable), in order to discharge the
possible remaining gas. Even in the delay timer is in operation, it is possible to return
the exhaust blower to operating mode by depressing the ventilator operation key.
The supply blower (air curtain type only) is interlocked with the exhaust blower. The
supply blower stop switch on the side of distribution board enables stop of the supply
blower only. This can be used for loading/unloading of the powder sample.
③
The windowpane can be opened/closed vertically.
The signs attached to the left side of windowpane and the left rail indicate the half open
position which is achieved by aligning the signs as shown in Fig. 4-1. This makes it possible
to use this product safer, by producing faster wind speed by using this product with opening
the windowpane narrower than that. Use this product with opening the windowpane narrower
than the half open position, as far as possible, except when opening than the half is required
for example carrying in or out an apparatus.
