5. INSTALLING AND PIPING THE DSP [Ventilation of Air Compressor Room]
5.5 Ventilation of Air Compressor Room
1. Stop the ventilating fan when the
DSP
has stopped.
2. Keep the ventilating fan operating while the
DSP
is
operating. Resistance of the un-operated ventilating fan
may reduce the performance of the DSP cooler.
3. Duct is to be detachable so that you can service the
DSP
easily.
①
Ventilation with Ventilating Fan (Figure A)
For a small air compressor room, install a ventilating
fan with a capacity as specified by the Technical Data
for Room Ventilation. Position the ventilating fan as
high as possible on the wall and provide the air
compressor room with an air intake opening on the
bottom of the wall.
Install the
DSP
to direct its air exhaust louver to the
ventilating fan and its air intake louver to the air
intake opening.

CAUTION
Provide a ventilating system to the air com-
pressor room in the event of a room tempera-
ture exceeding the allowable ambient operat-
ing temperature of 40°C (104
℉
). Operating the
DSP
under the ambient operating temperature
above 40°C (104
℉
) may cause a serious prob-
lem to the air end.
