Main Power Disconnect Switch; Air Distribution System - DeWalt DXCMV7518075 Guide D'utilisation

Main power disconnect switch

Install a main power disconnect switch in the line from the panel
to the compressor. The main power disconnect switch must be
located near the compressor, for ease of use and safety. When
turned OFF, the main power disconnect switch shuts off all
power to the compressor. When it is turned ON, the compressor
will start and stop automatically, controlled by the pressure
switch.

Air Distribution System

WARNING: Risk of bursting. Plastic or PVC pipe is not designed
for use with compressed air. Regardless of its indicated pressure
rating, plastic pipe can burst from air pressure. Use only metal pipe
for air distribution lines.
INSTALLING AND DISCONNECTING HOSES
WARNING: Risk of unsafe operation. Firmly grasp hose in hand
when installing or disconnecting to prevent hose whip. Ensure
regulated pressure gauge reads 0 psi.
The next figure represents a typical air distribution system.
The following are tips to remember when setting up the air
compressor's air distribution system.
NOTE: Compressed air from oil lube air compressors will contain
wa ter condensation and oil mist. Several drains, traps and filters
will be needed to supply air without water (including aerosols) or
oil to spray equipment, air tools and accessories requiring filtered
air. Always read the in struc tions for the air tools and accessories
being used.
• Use pipe that is the same size as the air tank outlet. Piping that
is too small will restrict the flow of air.
• If piping is over 100' (30.5 m) long, use the next larger size.
• Bury underground lines below the frost line and avoid pockets
where condensation can gather and freeze. Apply pressure
before underground lines are covered to make sure all pipe
joints are free of leaks.
• A flexible coupling is recommended to be installed between the
globe valve/air discharge outlet and main air distribution line to
allow for vibration.
• A separate regulator is recommended to control the air
pressure. Air pressure from the tank is usually too high for
individual air driven tools.
• DO NOT install lubricators between the tank and any spray
equipment, air tool or accessory requiring oil-free filtered air.
• Drain all traps, filters and dirt legs daily.
