3-1) See to it that the ambient temperature is -1〜52℃.
3-2) Provide a space of approximately 500mm at the top, bottom and front in
order to enable the replacement of desiccant tube, solenoid
valve ,etc .convenient.
3-3) Install a regulator, filter and Microalescer in the primary side in order
to upkeep the performance of desiccant. Install the filter also in the
secondary side. (See
“
Installation Drawing
”
on page 4.)
3-4) Install pipes to the inlet and outlet of heatless air dryer, taking due care
that there mis no leakage.
3-5) Connect the power source according to the plate on the heatless air dryer.
3-6) Connect a ground to the grounding terminal of the heatless air dryer left
side. (screw size: M4)
3-7) At the time of maintenance and check, install a by-pass circuit with a stop
valve if the flow inside the pipe can not be shut off.(See
“
Installation
Drawing
”
on page 4.)
3-8) Install plugs to the inlet and outlet not in use in order to avoid leakage.
4-1) Turn on the power source of heatless air dryer only after applying pressure.
Turning on the power source before applying pressure (particularly at
pressure less than 0.2MPa) may deteriorate the function of ball check,
causing excessively high rate of regenerative purging at the beginning.
4-2) The outlet flow rate extremely exceeding the specified value may deteriorate
the function of ball check, leading to excessively high rate of regenerative
purging. Hence due care shall be paid to this regard.
4-3) The desiccant, not used over a long period(approximately one week), may have
become wet. In such case, stop the secondary valve of heatless air dryer
and carry out regenerative purging for about 30 minutes before operation.
4-4) The regenerative purging is set to change over from left to right and vice
versa every 30 seconds (every 2minutes in the case of HD-6 and HD-9). Make
sure that the change-over is made properly as specified.
4-5) Replacement of desiccant
The desiccant tower consists of spring, desiccant, porous sheet, filter,
etc, and is installed to the main body. Refer to LEST OF SPARE on page 12
for replacement of desiccant. However, replacement shall be made every 1.5
〜2 years.
Execute it according to the following notes when you remove the desiccant
tower.
