Filling System with Seal Liquid
If the process fluid being measured must not come in contact with the transmitter, the transmitter
lines must be filled with a suitable seal liquid. The procedure to do this is as follows:
1. If the transmitter is in service, follow the procedure for “Taking the Transmitter Out
of Operation” on page 18.
2. Close both process shutoff valves.
3. Open all three valves on 3-Valve Manifold.
4. Partially open vent screws on transmitter until all air has been forced out of
transmitter body and lines. Close vent screws.
5. Refill tee connections. Replace plugs and close bypass valve. Check for leaks.
6. Follow procedure for “Putting Transmitter into Operation” on page 18.
!
CAUTION
To prevent loss of seal liquid and contamination of process fluid, never open both
process shutoff valves and manifold shutoff valves if bypass valve is open.
Positioning Housing
The transmitter housing (topworks) can be rotated up to one full turn in the counterclockwise
direction when viewed from above for optimum access to adjustments, display, or conduit con-
nections.
!
CAUTION
1. Do not rotate the housing more than one turn from the as received position. If
there is doubt about the housing rotational position, turn fully clockwise and
then back off no more than one full turn.
Positioning Display
The display can be rotated within the housing to any of four positions at 90 ° increments. To do
this, refer to Figure 7 and perform the following:
1. Turn off power source to transmitter.
2. Screw in cover lock (if present) and remove the electronics compartment cover by
rotating it counterclockwise.
3. Remove electronics module by unscrewing two screws closest to sides of transmitter
and pulling out module.
4. If turning display 180 °, turn and return module to housing by reversing Step 3.
