INSTALLATION
3.7
Install or replace the Pump Display Terminal and optional
accessories (if necessary)
3.7.1
Install the Pump Display Terminal
CAUTION
It is imperative that the Pump Display Terminal is stored in the recess after installation or use. Placing it on a
hot surface, such as on top of the enclosure, may adversely affect the long-term reliability of the terminal.
1. Unpack and inspect the Pump Display Terminal.
2. Refer to Figure 17. Remove the blanking panel (1) from the dashboard (2).
3. Fit the connector (4) on the end of the cable (7) to the Pump Display Terminal connector (6) in the recess (5) in
the dashboard.
Note:
The Pump Display Terminal connector (6) is intended for use by the Pump Display Terminal only, and should
not be mistaken for a Portable Personal Computer port.
4. Place the coiled cable (7) in the recess, then place the Pump Display Terminal(8) in position in the recess (5).
3.7.2
Install optional accessories
Accessories are not yet available for iF1800 rapid loadlock dry pumping systems. Please contact your nearest Edwards
for more information.
3.8
Connect the iF inlet to your vacuum system
Note:
If required (that is, if you will use the iF system in an area subject to high RF (radio frequency) emissions),
connect the end of the iF earth (ground) cable to one of the bolts that you use to connect the inlet-flange
of the iF system to your process system. refer to Section 3.15.2 for more information.
When you connect your iF system to your vacuum system, take note of the following:
To get the best pumping speed, ensure that the pipeline which connects the vacuum system to the iF system
is the minimum length possible and has an internal diameter not less than the iF system inlet-port.
Ensure that all components in the vacuum pipeline have a maximum pressure rating which is greater than the
highest pressure that can be generated in your system.
Incorporate flexible pipelines in the vacuum pipeline to reduce the transmission of vibration and to prevent
loading of coupling-joints. We recommend that you use Edwards braided flexible pipelines.
Adequately support vacuum pipelines to prevent the transmission of stress to pipeline coupling-joints.
On very dusty applications, use a low-impedance inlet-filter to minimise damage to the pump.
Incorporate a pressure gauge in the inlet pipeline, so that you determine that the iF system operates
correctly.
You must be able to isolate the iF system inlet from the atmosphere and from your vacuum system if you
have pumped or produced corrosive chemicals.
Use the following procedure to connect the inlet of the iF system to your vacuum inlet pipeline:
1. Remove the temporary cover or blanking plate from the inlet of the iF system. Retain the nuts, bolts, washers
and blanking plate for future use. Retain the temporary cover for future use on non-contaminated pumps only.
2. Use the 'O' ring supplied and suitable nuts, bolts and washers (not supplied) to connect the inlet-flange of the iF
system to your vacuum system.
