１．Installation① Install it in a horizontal position.
② Please fix it firmly if necessary.
③ Places that cannot be installed or used
・ Place with vibration
・ Places exposed to wind and rain outdoors
・ Top of fever
・ In a closed room and in a case・ A place where the back is close to a wall
・ Places above 1000m above sea level・ Places with an ambient humidity over 85% R.H.
・ Places other than ambient temp 0 to + 40 ° C
・ Near combustibles
・ Places with a lot of dust, dust, etc.
・ Places where acid gas, corrosive gas, etc. are floating
・ Places with low atmospheric pressure
・ Places with conductive suspended matter (carbon fiber, etc.)
atten:：

When carrying, do not hang a hoist or hanging band on the handle.

２．Piping① fix the piping to the outlet
Due to the characteristics of the flexible hose, hot air leaks from the flexible hose piping to the outlet. The leaked hot air will flow
back into the multi-dryer and cause damage to the electronic devices in the operation panel. Use the enclosed glass tape to prevent
air leakage and install the flexible hose piping to the outlet② Make the piping as thick and short as possible, and install it with a gentle bend.
③ Be sure to insulate the piping sufficiently.

３．Power supply① Ask an electrician for power connection and grounding work.
② Do not use the 100V type with the same outlet power supply at the same time as other devices.
③ For 200V type, use the attached outlet for wiring.
※ Connect the 200V type power cord according to R (red), S (black), and ground (green + yellow: with ground seal).

④ Be sure to use a commercial power supply (50 / 60Hz) with a sinusoidal waveform for the multi-dryer.
Never use a power supply that has distorted waves containing harmonics. Also, take sufficient measures toprevent surge voltage and noise from entering the power supply.
⑤ Please provide a dedicated circuit. When installing an earth leakage breaker, make a decision with asensitivity current of about 50mA as a guide.
※ The sensitivity current of the earth leakage breaker is generally about 10 times the initial leakage current.
⑧ To prevent electric shock accidents, perform grounding work (class D grounding).
Atten:

Please note that wiring that is too long will cause a voltage drop.

Atten:

Be sure to shut off the power supply during wiring and inspection. Even if the power switch of the main unit is turned off,the operation circuit of the multi-dryer is still energized, so be sure to turn off the factory power supply (primary power
supply). If you work with the power turned on, you will get an electric shock.

Atten:

If you provide an outlet for the connection, ensure sufficient capacity. Please refrain from using the outlet as much as
possible because the outlet may generate heat or break down due to poor contact due to deterioration over time, phaseloss, etc.
A multi-dryer is a device mainly used in an industrial environment. When used in a residential environment, etc., there is arisk of radio interference. At that time, the user of this product may have to take appropriate measures to reduce the
obstacle.

Atten:※When using a single-phase 100V power supply with a single-phase three-wire low-voltage distribution system,
the single-phase 200V power supply can be easily taken out from the distribution board. If you are using a single-phase 200V model,
please consult with an electrician, including the power supply capacity.

－１－※Please make changes with the external
operation function turned off.

４．Intermittent operation●

When the temperature of the constant temperature bath is controlled using an external sensor, the multidryer is stopped when the temperature inside the constant temperature bath reaches the set temperature,and the temperature inside the tank is -5 ° C to -10 ° C (optional). Once the setting is reached, you canperform energy-saving operation to restart the operation of the multi-dryer.

① Set the hot air temperature while stopped.
Since this set temperature is the upper limit temperatureof the discharge port of the multi-dryer, set thetemperature in consideration of the set temperature of
the external sensor + heat dissipation from the piping,etc. (If there is no upper limit on the discharge port
temperature, set it to 300 ° C). ..

③ Set the temperature of the place controlled by
the external sensor.

② Remove the cap of the external sensor socket
and plug in the external sensor KX350AP (theexternal sensor is an automatic setting type by
mounting).
The external sensor lamp (orange) lights up and "0" isdisplayed in the set temperature section.

④ Press and hold the hot air switch and hot air
temperature up key for about 3 seconds.
"Loc" is displayed in the hot air temperature section, and"Lc1" is displayed in the set temperature section.

－２－

⑤ Press the hot air switch 8 times.

⑥ Press the hot air temperature up key once toturn the set temperature display to "ON".

"PAo" is displayed in the hot air temperature section, and"oFF." Is displayed in the set temperature section.

⑦ Press the hot air switch once to display "SP1" on the
hot air temperature display, and set the desired
temperature (-5 ° C to -10 ° C) with the hot air
temperature up / down keys.

⑧ Press the hot air switch twice to return to thenormal operation state, and press the hot air
switch to start the hot air operation.
The hot air lamp (orange) lights up, the external sensor lamp
(orange) blinks, and hot air operation starts.

When the sensor temperature in the constanttemperature bath reaches the set value, the multidryer stops operation, and then starts operation again
when the temperature inside the tank drops to the set
arbitrary temperature (-5 ° C to -10 ° C). After
that, the intermittent operation is continued in thesame manner.
However, we do not switch from operation within 1
minute to stop and from stop to operation.
The hot air lamp blinks while the operation is stopped during
intermittent operation (the external sensor lamp keeps
blinking).

To cancel the intermittent operation, return tothe state of ⑤ above (PAo oFF).

－３－５．Each abnormality indication● When the multi-dryer is abnormal, the details of each abnormality are displayed and the operation is stopped (only theinternal temperature abnormality is in the ventilation operation state). Be sure to remove the abnormality and thenrestart the operation by turning on the power switch again. (Depending on the abnormality, it may be possible torecover with the stop switch. Also, only the overheat for detecting the temperature of the heater case will be manually
restored.) ..

filters HAS-TF and HAS-43TF (1 set of 10
sheets).

caucion ： Never operate with the filter removed. If you inhale dust, the blower will break down.

７．When using as a shoulder type
● Multi-dryers HAS-17T, 27T, 37T are equipped with hanging brackets for shoulder belts for use as shoulder
type. By attaching a commercially available shoulder belt, you can carry the multi-dryer on your shoulder
and use it for spot drying and heating.
Hanging bracket

Cord band

When using it for carrying around,tie the power cable to the handle
with a cord band, and be careful
not to put a load on the power cable.

《ATTENTION》
Do not operate with the power cable bundled.
The power cable generates a lot of heat andmay cause damage.

Attach a commercially available
shoulder belt to the hanging
brackets (2 places)on the handleof the multi-dryer.
※Select a shoulder beltwith a load capacityof about 10 kg.

８．Maintenance and inspection● Inspection of suction port filter
The intake port of the multi-dryer is equipped with a filter. Always inspect the suction filter and clean it
regularly. If the filter is clogged, the temperature inside the heater case becomes abnormally high, causing
overheating or abnormal temperature.

voluntary inspection
In order to use this machine more safely, we recommend that you carry out a self-inspection if the usage
period exceeds 10 years.
【voluntary inspection point】
・ insulation resistance value
・ Inspection and cleaning of foreign matter inside the operation panel
・ heater current value
・ Inspection and cleaning of foreign matter inside the main body and suction port
・ Tightening inspection of each terminal block
・ Operation of electrical parts and heat generation inspection
・ Other visual inspection※ For self-inspection, ask the nearest electrician.
caution ： Never perform an insulation withstand voltage test on this machine (already done at the time of
shipment). It may cause a malfunction.
