Piping
●Before piping, thoroughly flush inside of each pipe to remove chips, coolant, dust, etc.
●When in piping, apply seal tapes or sealant on the threaded zone.
●Pay attention so that chips or sealant may not enter inside when screwing pipes or fittings.
Execute tightening in a proper manner in the range of the specified tightening torque.

<Example of piping connection>
・Do not use this product for other purposes than its original usage or the range of its
specifications.・Do not use this product with other gases other than air.
・Do not remove any part to use it for any other equipment, or do not use any other parts
than the specified items.
・Use the product in the range of working pressure being 0.3 to 0.7MPa.
・Note that hot air is discharged from the hot air exhaustion port during the product use.
Take care not to get burnt because the section protected with mesh may become as hot as
70℃at the maximum when the inlet air temperature is 20℃depending on the use conditions.
●Moisture contained in the compressed air to be supplied will cause freezing in the cold air
outlet.
If the nozzle is frozen, ice particles will take place in the cooling air.
For prevention of such trouble, be sure to supply dry air using an air drier or similar other devices.
●Install an air filter and a coalescing filter in order to prevent the perfoemance degradation due
to dust, lublicant or other substances.
●Use pipes and tubes of as large an internal diameter as possible in the piping to the spot cooler.
Thin pipes cannot supply compressed air sufficiently, decreasing the performance.
●If a tube or the like is used for piping to the cooling air outlet, be sure to minimize the length of
the tube, wrapped around with heat insulation material.
Adjustmentofcoolingairtemperature
Use the adjustment screw at the rear of the main unit for adjustment of temperature. Counterclock-
wise turning of the adjustment screw will lower the temperature, decreasing the cold air
flow rate. Clockwise turning of the adjustment screw will bring opposite results.

Air consumption
Fault and repair
If the temperature drop has become insufficient, make inspection in the following steps
(1)Make readjustment using the adjustment screw.
(2)Check for clogging of the filter or coalescing filter, causing the drop of supply pressure.
(3)Check whether the air is supplied sufficiently.
Note that the company shall not be responsible for anything that has been disassembled by the user.
Cooling capacity and flow
Note: The number of “Turns” given in the diagram indicates the number of turns of the adjustment screw, that is, the
number of times of turning back from the fully tightened condition.The “△Temprature䉝” means the temperature
determined by the subtraction of (The inlet air temperature −The cold air temperature).
This diagram shows the characteristics of a single spot cooler. In the actual use situation, the characteristics may be
different depending on the conditions.
