O-ring 49.21 x 3.53 EPDM
(gasket set 52005628)
grounding spring
flange
Loosen set screw at housing approximately 1 turn (Allen wrench AF 4)
Unscrew stop screw at hosuing approx. 4 - 5 turns (Allen wrench AF 2.5)
Pull housing off process connection
Attention: do not damage antenna cable!
Take off the antenna through a manhole in the tank by loosening the 4 screws
Loosen flange from tank and pull out of the tank together with the
antenna pipe.
The flange can be separated from the antenna pipe by removing
the 4 Allen screws (AF 5)
UNI-flange:
The parabolic antenna with antenna pipe and antenna cable are one complete
assembly that cannot be taken apart
Assembly
The assembly and installation has to be done in reverse order:
• UNI-flange: mount flange (14) and tighten Allen screws with 10 Nm
• Mount antenna pipe with flange on tank, and align t
•
• Lubricate the O-ring between process connection and housing with some silicon
grease before mounting
• Mount housing on antenna pipe (12)
• Tighten stop screw (11) until stop, then loosen ½ to 1 turn
• Adjust the grounding spring to make a conductive connection with the antenna
pipe (ground potential to antenna)
•
• Mount completely assembled instrument in tank
• Tighten set screw (10) firmly
• The warning sign “Avoid electrostatic charge at the antenna” must be attached to
the housing with a key ring
he alignment marker to the
tank wall (see next page)
Mount parabolic reflector through manhole in tank with 4 Allen screws (AF 5) to
the antenna pipe
Re-install electronics and all modules, make sure that the cables are not pinched
