AO2000-LS25 installation
Note
• Read all instructions carefully before installation.
• All housing parts are made of stainless steel or aluminum.
• All threads must be greased using suitable grease before
installation.
• Both receiver and transmitter units have optical windows
installed by the factory. The optical windows should not be
taken off and their angular positions should not be changed.
This is important for successful alignment.
• Make sure that the mains cable is disconnected or that the
power is disconnected before performing the electrical
connection.
• Make sure that the power plug is the disconnecting device
(no separate mains switch on device) and the power socket
should be placed easily accessible for the operator.
Perform installation of the device as described in the following
steps:
1. Install the purging flanges
5
on the stack flanges using 4
M16 × 60 screws each, see
All 4 bolts on either side must be tightened firmly to
compress the large O-ring.
Adjust the 4 locking screws prior to mounting the unit, to
assure good alignment of the unit and a uniform
compression of the O-ring.
• Install pressurized device purging as described in
on page 37.
2. Turn on the purge gas, see
on page 37
for details.
3. Place the window adapter ring
4
on the purging flange.
Make sure that the O-ring is firmly connected to the purging
flange and greased. The guiding pin on the purging flange
must fit the hole in the adapter ring.
