11. Connect the waveguide to the antenna with either an E-bend or H-bend wave-
guide. See the supplied instruction manual (C32-01903) in Antenna Unit for de-
tails.
1) Wipe the surface of the waveguide flange with a clean, dry cloth to remove
any foreign material.
2) Grease the O-ring and set it in its groove on the Antenna Unit.
3) Evenly coat the waveguide flange for the Antenna Unit side with supplied ad-
hesive.
Note: Apply an even coat of the supplied adhesive to the waveguide flange.
It should leak out slightly when the fixing bolts are tightened. Be sure no ad-
hesive contacts the choke groove and waveguide.
4) Connect the waveguide flange and then fix with the bolt.
Note 1: If it is necessary to open the front cover after installing the de-icer kit,
remove the de-icer power cable from the locking wire saddle shown in the fol-
lowing figure then detach the cover slowly to prevent damage to the heater
element.
Note 2: For the de-icer, take care not to hit the heater elements on the chassis
or radiator. If the heater hits something, unfasten the fixing screws for the
heater to adjust the position of the heater. Then fix the heater again.
5) Wipe out the excess adhesive of the flange.
12. Check that the gasket on the front and rear covers is seated properly, then
close the covers. The torque for the fixing bolts must be 10.0 N•m.
