Installing The Dsp Air Compressor - Hitachi NEXT Series Instruction Manual

5. INSTALLING AND PIPING THE DSP [Installing the DSP Air Compressor]

5.3 Installing the DSP Air Compressor

1. Keep flammable solvents or any other hazardous chemicals away from the DSP. Such chemicals may be
sucked by the air end, compressed, and exploded.
2. Do not use fire near the DSP; otherwise the sparks may enter the air end and burn it internally.
■ Install the DSP in a bright, wide, and airy room as follows:
Ventilating Fan
If you install the DSP in a
small room, provide a
ventilating fan to keep the
room temperature at 40℃
(104℉ ) or lower.
Piping and
Maintenance Space
Keep a space of 1.0 m (39
inches) or more to connect
a plant airline pipe and
ease the maintenance
servicing.
Plug the fork slots with
the fork slot covers
(standard accessory)
■ Install the DSP in a dry and dust-free room, and avoid the following.
Raindrops, Basements, Steam
These conditions may cause leakage,
condensation, rusting and CPU mal-
function.
■ Install the DSP on a level floor.
Installing on a level floor is required to keep an
adequate amount of lubrication oil in the DSP
and prevent excessive noise and vibration.
● Install the DSP indoors. Installing it outdoors may lead to a damage of the air end due to water vapor,
dust, etc.
● The DSP installation room must have an air intake opening and an air exhaust opening and must be
well ventilated. If the room is poorly ventilated, hot air exhausted by the DSP may cause the room
temperature to rise abnormally and in the worst case lead to damage of the air end.

WARNING
Maintenance Space
Keep a space of 1.5 m (59 inches) or
more to allow opening the front door.
Metals, Sand, Other Hard Materials
These conditions may cause deterio-
ration of motor insulation level, dam-
age to the air end bearings and CPU
malfunction.
Do not set the DSP
Prohibited
on the blocks.
CAUTION
Air Intake Maintenance Space
Keep a space of 1.5 m (59 inches) or
more. Note that the air intake grill is
located on the rear enclosure panel.
Foundation
Provide a vibration-absorbing mat if
the foundation is vibrative. If it is too
vibrative, look for another dequate
location.
Maintenance Space
Keep a space of 0.8 m (31 inches) or
more to connect the discharge
compressed air piping and for ease of
maintenance.
Harmful Gases
Chlorine, hydrogen sulfide, sulfurous acid, highly
（ ）
concentrated ozone, and ammonium gases
These conditions may cause oil deterio-
ration, corrosion of coolers and peeling
of the rotor coatings.
■ Do not install the DSP near a wall. Doing
this may cause the operating sound to
resonate and increase the sound levels.
