3 Installation
3.1 Unpack and inspect
Remove all packing materials and protective covers and check the AIM Gauge. If the AIM Gauge is damaged, notify
your supplier and the carrier in writing within three days; state the Item Number of the AIM Gauge together with your
order number and your supplier’s invoice number. Retain all packing materials for inspection. Do not use the AIM
Gauge if it is damaged.
If the AIM Gauge is not to be used immediately, replace the protective covers.
Store the AIM Gauge in suitable conditions as described in Section 6 .
Note: Please consult your supplier in case of any difficulty.
3.2 Fit the AIM gauge to the vacuum system
The AIM Gauge can be mounted in any orientation. To avoid the build up of debris or condensable material in the
body tube of the AIM Gauge (which will probably cause pressure measurement errors), we recommend that you install
the AIM Gauge vertically as shown in
Figure 2 .
Use an O-ring/centring ring or co-seal and clamp to connect the NW25 flange of the AIM Gauge to a similar flange on
your vacuum system.
If required, you can turn the end cap (relative to the magnet housing) so that the electrical connection socket is in
a convenient position on your system; refer to
Figure 1 and use the following procedure: hold the magnet housing (4)
and turn the end cap (1) in a clockwise or anti-clockwise direction (arrow B) until the electrical connection socket
(7) is in the required position.
3.3 Electrical connection
When using a cable longer than 30 m, full compliance with European Standards requires an in-line surge suppressor
(please refer to
Section 7.3 ).
Note: Ensure the cable is installed in such a way as to not cause a trip hazard.
3.3.1 Connect to Edwards controllers or AGD display
Connect the AIM Gauge to the controller or display with a cable which is terminated in suitable connectors. Suitable
cables are available from Edwards (refer to
Section 7 ).
WARNING
The AIM gauge incorporates magnets. Keep away from heart pacemakers, computers, credit cards
and any other magnetically sensitive devices.
WARNING
If the AIM Gauge malfunctions, the AIM Gauge pressure output may be incorrect. If such a failure
could cause injury to people or damage equipment, you must install a suitable control system to
indicate the failure and, if necessary, to close down your process system.
