Thank you very much for your purchase of SSTB type silent blower. This instruction manual is for your safety when using IE3 motor (small low-voltage three-
phase cage induction motor) or IPM motor (permanent magnet synchronous motor) (hereinafter referred to as IE3 motor or IPM motor) And instructions for
handling. In the text, the content that distinguishes IE3 motor and IPM motor is described in IE3 motor (left side) and IPM motor (right side) either separately
or together. Please read this against the corresponding motor.
For IPM moto r, re ad thi s blow er instru c tion manu al and the ins truc tio n man ual for the ded ica ted inv e rte r uni t (Tosh ib a
inv erte r) re quir ed whe n d rivin g the mot or, and us e i t pr ope rl y.
Please read this manual for the perfect capability to be assured and also for its maintenance and inspection.
Please be sure to deliver this instruction manual not only to the contractor but also to the end user.
1．Inspection confirmation at the time of purchase (IE3 motor)
Please check with the nameplate of the blower and the specification table
below to see if it is the product you ordered.
Especially depending on the area, there is a distinction of 50 · 60 Hz so
please check. Also please check for damage etc. during transportation.
1．Inspection confirmation at the time of purchase (IPM motor)
Please check with the nameplate of the blower and the specification table
below to see if it is the product you ordered.
For inverter drive there is no distinction of 50 · 60Hz depending on the
region. Also please check for damage etc. during transportation.
2．Outline(IE3 motor, IPM motor)
This is a “low noise type blower” realized by improving the air pressure characteristics and suppressing noise of our long-reputed WTB Series.
Owing to the roll filter employed, the filter can be replaced easily with no need of cleaning the filter.

3．Precautions when using (IE3 motor)
・Because IE3 suppresses generation loss, rotation speed generally becomes
faster than IE 1 (up to now motor). When IE1 (standard motor) is replaced
with IE3 (high efficiency motor), the output of the motor increases as this
rotational speed increases. Motor efficiency is high, but as the output
increases, power consumption may increase.
・Also, since the (primary and secondary) resistors are lowered to reduce
copper losses, the starting current is higher for IE1 (up to now motor), and
it is necessary to change wiring breaker, electromagnetic switch, thermal
relay, etc. It may become.
3．Precautions when using (IPM motor)
・IPM motors can not be operated by directly connecting a commercial power
supply (50/60 Hz).Drive with the inverter for IPM motor operation. In
particularly important equipment, it is recommended to prepare an
inverter spare in case of failure.
・Since an IPM motor needs to be controlled based on the position of the rotor,
it is not possible to operate multiple IPM motors with one inverter.
・If you combine an IPM motor with an inverter from different manufacturers,
the inverter or motor may malfunction, or reverse operation depending on
the machine may cause unexpected behavior.
・When the rotor of the IPM motor is mechanically rotated externally, the
magnetic field of the permanent magnet generates an induced voltage
between the motor terminals. Therefore, the inverter may be damaged
depending on the risk of electric shock and the rotational speed at the time
of power off.
・If the cable between the IPM motor and the inverter is long, it may not be
able to operate normally due to the increase of inverter surge and the
attenuation of sensor signal.
・The IPM motor has a permanent magnet inside, which requires careful
handling. Please contact the manufacturer you purchased for maintenance.

discharge flow rate exceeds the rated flow rate due to, for example, no resistance at the outlet or downstream from the outlet, the
overcurrent could cause failure or seizure of the motor. Be sure to use the burner in a manner that the rated current value and rated flow
rate are not exceeded.

11．Star delta starting(IE3 motor)
1). Notes on star delta start
There are three electromagnetic contactor type and two magnetic contactor type in the star delta starting method. 2 Electromagnetic contactor type circuit
is simple and economical, but since voltage is constantly applied to the windings of the motor even when the motor is stopped, safety during maintenance
and inspection, dust and humidity are high Because it is necessary to pay attention to insulation degradation between the windings of each motor phase
winding and winding to ground at the place, 3 electromagnetic contact type is recommended.
2). Current detection method of thermal relay
As shown in the figure below, the thermal relay at the star delta start has the line current detection method and the phase current detection method, and
the selection of the heater rating is different. In the line current detection method, the heater rating is selected based on the motor full load current. On the
other hand, in the phase current detection method, the heater rating is selected based on the current of 1 / √3 of the full load current of the motor. In this
method, the frame size of the thermal relay can be made smaller than that of the line current detection method, but since the wiring size of the motor circuit
does not change in any detection method, in the case of the phase current detection method, Since it is necessary to consider whether wire connection is
possible or not, the line current detection method is recommended.

14．Before getting into operation(IE3 motor)
＜Check of direction of rotation＞
1）Rotate the impeller slowly by turning ON/OFF the started switch instantaneously.
2）Looking through the rotation instruction cover, check whether the rotation confirmation mark (yellow) on the spindle shows the same direction as the
direction of the arrow. If not, turn OFF the main power immediately, and correct the connection.
＜Starting operation＞
1）Turn on the start switch of a blower.
2）When the blower becomes steady, increase the load to the maximum level, and check whether the current value of the motor is not above the rated value.
(Never run the motor under overloaded condition.)
3）If the operating air quantity is reduced excessively, a surging phenomenon (pressure fluctuation like waving) may occur. If such phenomenon occurs, it is
advisable to provide a vent valve on the delivery side.
15．Maintenance inspection(IE3 motor)
Please inspection and maintenance in the following way.
1）Even if there is not abnormality, please do the inspection in the main body of impeller and blower once a year.
2）Occasionally check the tightening of the bolts of each part.
3）Always pay attention to the abnormal sound, vibration, overheat of the blower body and any other abnormality.
4）Please rolling up the dirty roll filter and clean it.

16．Roll filter(IE3 motor, IPM motor)
Please check the filter periodically, and before it starts decreased pressure
by the clog of dust etc., Rolling up a roll filter.
The roll filter is supposed to be replaced by rolling up once every week or
so, but this replacement frequency may be adjusted according to the usage
and the environment.
One roll filter lasts for about one year.
●Rolling up the roll filter
1）Loosen the wing nut B.
2）Release the latch to open the presser foot.
