6.6 Connecting the Air Sampling Pipe
The air inlet port is designed to fit a standard pipe of 25mm (1in) OD. A tapering of the air inlet
port prevents the pipe from being inserted beyond 15mm (5/8in).
Note Where it is common practice to use ¾ inch pipe which has a 1 1/16 inch OD, a
suitable adaptor should be used to connect the pipe to the inlet manifold. Such an
adaptor is supplied with the LaserCOMPACT in the appropriate territories.
a) De-burr and square off the end of the sampling air pipe. Ensure the pipe is free from swarf.
b) Remove the plugs from the inlet and exhaust ports.
c) Insert the pipe into the inlet port ensuring a firm fit. DO NOT glue this connection.
d) Pipe the exhaust when necessary.
Caution DO NOT GLUE THE AIR INLET AND EXHAUST PIPE CONNECTION
Glued connection makes disconnecting the sampling air pipe from the
LaserCOMPACT for maintenance extremely difficult and will result in damage
to the equipment.
