INSTALLATION INSTRUCTIONS

Connection of Compressed Air to the Laser
WARNING: Operating air pressure is 4 bar!
Connect the hose from the air installation kit to the laser compressed air
inlet.
A safety valve is at the air inlet. It opens if the air flow at the inlet exceeds
450lpm.
For safety reasons there are two separate outlets for compressed air. To
one of them a silencer is connected (Air Outlet 2). A hose is connected to
the other one (Air Outlet 1). The end of this hose has to be installed in a way
that it does not get blocked at any time or that water may infiltrate into the
hose. Please check the outlets for blocking and dirt on a regular monthly
basis. Blocked outlets may damage the laser!
One may check the function of the safety valve upon installation. Turn the
line pressure up to 3,5 bar to 4,5 bar until the safety valve opens. Reduce
the pressure by 01, bar to ensure the correct air flow. Please note that air
pressure is only applied to the safety valve if the switch valve inside the
laser head is open. If it is closed there is no air flow through the laser head.
Both air outlets must be kept clear. Only one silencer has to be installed to
the air outlets. Do not use silencers on both air outlets. Do not swap inlets
and outlets for compressed air.
Check the silencer for dirt once a year. Remove the stainless steel housing
to check the silencer.
Minimum inner diameter of the outlet hose must be 12 mm. The length of
the outlet hose must not exceed 4 metres.
