5.2.3 Air modules, Transceiver and Reflector
After completing the welding of the sockets and the support and alignment brackets, the
air modules can be mounted onto the welding sockets. To avoid gas leaks, it is recom-
mended to use e.g. Teflon thread tape in between. Fix the air module in position with the
lock screw. Normally the best position is with the purge air supply connection facing down.
After completing the mounting of the air modules, the transceiver and reflector can be
mounted on each side of the stack. The transceiver and reflector module are then secured
by tightening the ring nut.
5.2.4 Audit Module
The audit module is an optional item that enables the user to validate the performance of
the monitoring system e.g. in relation to demonstration of compliance requested by au-
thorities. Only one audit module is needed for each set of transceiver/reflector. The audit
module can either be mounted on the transceiver side or the reflector side, however it is
important to have easily access to the audit module. The audit module is designed to fit in
between the air module and the transceiver/reflector as shown on Figure 5-3 & Figure 5-
4.
