3.2 Required tools
The following tools are required:
 Spanner 55/65 for SmartRadar (Honeywell Enraf part number S0186396),
or wrenches with seizes 55 mm (23/16”) and 65 mm (29/16”).
 Standard wrenches for loosening flange/adapter plate fastening bolts.
 Small screw driver or pliers.
3.3 Disassembly of the components around the Tank Separator
The two O-rings which are to be exchanged are located inside the Tank
Separator. Hence, the SmartRadar FlexLine housing must be removed from the
Tank Separator, the flange (or adapter plate) with the Tank Separator must be
removed from the tank nozzle (or stilling well), the Antenna must be removed
from the Tank Separator and the Tank Separator must be removed from the
flange (or adapter plate). Refer to figure 3-1.

 Note the level (and temperature) reading of the SmartRadar FlexLine for
later use.
 Switch off supply from the SmartRadar FlexLine.
 Unscrew the SmartRadar FlexLine housing (1) by loosening the nut to
which it is fixed to the Tank Separator.
 Place the SmartRadar FlexLine housing carefully aside the Flange/Adapter
plate.
 Loosen the bolts from the Flange/Adapter plate and lift the Flange/Adapter
plate until the Antenna is free from the tank nozzle (stilling well).
 Straighten the Antenna locking ring (11).
 Loosen the Antenna lock nut (12) with spanner 55/65 (or wrench 55 mm
(23/16”)).
 Pull out the Antenna.
 Loosen the Tank Separator nut (2) with spanner 55/65 (or wrench 65 mm
(29/16”)).
 Remove the Tank Separator (4) from the Flange/Adapter plate (5).

3.4 Removing the original (or expired) O-rings
Refer to figure 3-2.
The two O-rings to be exchanged are indicated by A and B.
FIG.3-2 O-rings in Tank Separator
.
Existing O-rings are:
A = O-ring  85.32 x 3.53 mm; material: FPM
B = O-ring  38.00 x 4.00 mm; material: FPM
 Remove the existing O-rings, marked A and B as indicated in figure 3-2.
For removal of the O-rings, a small screw driver or pliers can be used.
 Clean the inside of the Tank Separator.
3.5 Installing O-ring B and re-installing Antenna
 Place O-ring B from the kit inside the Tank separator (4). Use with this
O-ring the supplied grease while wearing the protective gloves.
 Apply some grease (mind to wear the protective gloves) on the lower screw
thread of the Tank Separator.
 Shift the Antenna locking (11) ring over the Antenna stem.
 Slide the Antenna (13) into the Tank Separator (4) (some force is required
to push the Antenna stem over the O-ring). Mind the orientation of the
locking pin (9) on the Antenna stem so it is aligned with the corresponding
hole inside the Tank Separator. The Antenna is completely shifted into the
Tank Separator when the circlip (10) on the Antenna stem is at a distance of
approximately 2 mm (1/16”) from the Tank Separator (4) (refer to figure 3-3).

FIG.3-3 Detail of distance Circlip on Antenna stem – Tank separator
 Place the Antenna locking ring (11) over the Locking pin of the Tank
Separator (4).
 Fasten the Antenna locking nut (12) with spanner 55/65 (or wrench 55 mm
(23/16”)).
 Bend the Antenna locking ring (11) against one of two the flat parts of the
Antenna locking nut (12) (mind that the hole in the Antenna locking ring
remains over the locking pin).
3.6 Re-installing the Tank Separator on Flange / Adapter plate
 Place O-ring A from the kit on the flange of the Tank separator (4).
 Insert the Tank Separator (with Antenna) from underneath the Flange/Adapter
plate (5). Mind locking pin!
 Apply some grease (mind to wear the protective gloves) on the screw thread
of the Tank Separator just above the Flange/Adapter plate.
 Place the M55 inside star washer (3) over the Tank Separator (4).
 Fasten the tank separator nut (2) with spanner 55/65 (or wrench 65 mm
(29/16”)).

3.7 Re-installing the Flange/Adapter plate with Antenna on tank nozzle / stilling
well
Refer to the Installation Guide SmartRadar Antennas.
 Place the gasket on the roof nozzle / stilling well flange (check if new gasket
is required).
 Place the Flange/Adapter plate with Tank Separator and Antenna according
to the instructions of the Installation Guide SmartRadar Antennas on the
tank nozzle (stilling well). Mind the orientation of the Antenna (SmartRadar
FlexLine housing) in case of free space Antenna application.
 Secure the Flange/Adapter plate.
WARNING:
For a proper bounding of the Flange/Adapter plate, install a braided ground cable
or copper strip under one of the Flange/Adapter plate bolts.
Place sharks ring between braided ground cable/copper strip and flange.
3.8 Re-installing the SmartRadar FlexLine on the Tank Separator
 Apply some grease (mind to wear the protective gloves) on the top part of
the screw thread of the Tank Separator
 Place the SmartRadar FlexLine on the Tank Separator. Mind the position of
the locking pin!
 Secure the SmartRadar FlexLine housing by the nut on the Tank Separator.
 Apply power to the SmartRadar FlexLine.
When the SmartRadar FlexLine is powered up, do check if its readings are
correct (if level reading has changed from before the O-ring exchange, perform a
level check by means of a manual dip).
 If applicable, seal the SmartRadar FlexLine according to W&M procedures.
 If the SmartRadar FlexLine is used in a SIL loop, the 990 SIL checklist
should be completed by a qualified technician to validate the instrument.

3.9 Labeling the SmartRadar FlexLine
 Engrave, or stamp the installation date of the special O-rings (month – year
will do) on the black part of the Special O-ring indication plate (refer to figure
3-4).
 Secure the label by means of the sealing wire and seal to the rod on the
rear side of the FlexLine housing (refer to figure 3-4).
