immediately, then replace the protective flange cover and store in an area
where the temperature range is controlled between -20 to +85°C.
The Model 730 can be mounted in any orientation on the vacuum system.
To avoid the buildup of debris or condensable material in the measurement
cavity of the Model 730 (which may cause measurement errors), we recom-
mend that you install the Model 730 vertically with the tube facing down.
Outline drawings showing the external dimensions are shown in Figure 1
(see below).
To connect the Model 730 to your system use the appropriate hardware
for the type of fitting:
• Use a Swagelock® Ultra Torr vacuum fitting to connect to the O.5” or
0.25” OD tube.
• Use an O-ring/centering ring and clamp to connect to the NW16 or 25
flange options.
Note: A stepped O-ring carrier may be used to connect the NW16
flange to an NW10 flange on the system.
• Use a Male 4 VCR™ or 8 VCR™ Face Seal Fitting and sealing
gasket to connect to the female swivel 4 VCR™ or 8 VCR™ Style Face
Seal Fitting.
Note: Tighten fittings in accordance with the manufacturer’s
specifications.
