Installation
Best practices – pneumatics
WARNING: Before installing the pneumatics,
ensure that the machine is safe to work on by
isolating the air supply.
NOTE: Valve Kv (Cv) ow coefcient, pipe
length and pipe diameter will affect operating
performance. Exhaust lines from valves must be
routed to a clean isolated area away from any
electrical connections. An exhaust silencer/lter is
recommended.
For air supply see “Pneumatic supply” in
specication on page 5.
• Where possible, tap into the air supply that
exits the machine air supply lter/regulator
unit. Do not connect the APC to an oiled air
supply.
• Before connecting the air pipe to the inlet of
the APC unit, briey switch on the air supply
to clear out any debris from the pipe. When
no more debris is emitted, switch off the air
supply and connect to the APC.
• When installing the air pipe supply to the
APC, keep runs as short as possible to
minimise pressure drop.
• If the temperature of the air supply is greater
than +5 °C (+41 °F) above ambient and is
humid, an air dryer will be required.
