MOUNTING THE AIR PLENUM AND WEATHER COVERS

WARNING! CONTROL UNIT, TRANSCEIVER & RETRO SERIAL NUMBERS MUST
MATCH.
After the installation site has been selected and the platform requirements have been met, the mounting flanges should be installed
and aligned as described on Drawings OPM6130 and 6131. Flanges should be installed with the mounting faces on the vertical plane.
1) Before installing the Transceiver, Retro reflector or any type of
weather cover remove the air plenum from both the Transceiver
and retro reflector. Removal will make the installation easier and
less chance of damage while mechanical attachment of the air
plenums and optional weather covers when provided.
2) If the transceiver and retro reflector have been shipped from the
factory with the air plenum attached, un-clip both hold down
latches, swing open and lift up & off the hinge pins. Place the
Transceiver and retro in a safe place.
3) The air plenum is attached to the customer supplied 3" pipe flange
by four 2 1/2" long 5/8-11 bolts. Working from the 3" flange the
correct assembly is: gasket then air plenum.
4) If you have weather covers remove the two (2)-weather cover hood hinge pins located on the upper right and left
hand corner of the hood. The air plenum and weather cover are attached to the 3" pipe flange by four (4) 2 1/2"
long 5/8-11 bolts. Working from the 3" flange the correct assembly is; gasket, weather cover mounting plate,
gasket, mating flange & air plenum. Place the 5/8-11 bolt through the top hole of the middle plate. Place a flat
washer between the middle plate and mating flange and pass the bolt through. Slip a split lock washer over the
bolt and secure with a nut.
Repeat for the remaining
three mounting bolts.
5) Any wiring or air hoses can be
connected now.
