5.3 Installing the Air Compressor

(Selection of a proper installation location is essential to a long service life for the Air Compressor.)
1. Keep flammable solvents or any other hazardous chemicals away from the air compressor. Such
chemicals may be ingested into the air compressor and could cause an explosion during the
compression process.
2. Do not use fire near the air compressor; otherwise the sparks may enter the airend and burn it internally.
■  Install the air compressor in a bright, wide, and airy room as follows:
Ventilating fan
If you install the air
compressor in a small room,
provide a ventilating fan to
keep the room temperature
at 104℉ (45℃) or lower.
Maintenance Space
Plug the fork slots with
the fork slot covers
(standard accessory)
■ Install the air compressor in a dry and dust-free room, and avoid the following.
Raindrops, Basements, Steam
Causes electric leak, generation of
drain/rust, microcomputer malfunction.
■ Install the air compressor on a level floor.
To ensure an appropriate amount of oil
To prevent noise and vibration
● Install the air compressor indoors. Installing it outdoors may lead to damage of the airend due to
water vapor, dust, etc.
● The air compressor installation room should have an air intake opening, an air exhaust opening and
have good ventilation. If the room is poorly ventilated, hot air exhausted by the air compressor may
cause the room temperature to rise excessively and lead to damage of the air compressor.
