DATAFLOW RTU
14.1.2 Optional mounting bracket RITRON part number 25104600 is available for
DATAFWW RTU.
To install this
bracket to the case, remove and save the four thread-forming screws described in paragraph 14.1 to attach the
mounting bracket to the case. Be sure the narrow portion of the keyhole is positioned towards the top (UHF
antenna connector) of the
DATAFLOW RTU.
Use the recommended hole pattern for the optional mounting
bracket shown in Figure A5 .

Cover/Waterproofing the Antenna Connection
14.2.1
The DATAFLOW RTU
is
weather-resistant
if
it has been properly sealed.
If you have opened or
disassembled the device, refer to the following instructions.
14.2.2 Sealing the Housing Cover: Inspect the seal and mating surfaces for flaws (tears, gaps, dents, etc.). Repair the
surface or replace the part as necessary. Purchase replacement cover gaskets through Ritron: Part No. 25605100.
Insert the seal in the cover.
Thread
the four
(4)
screws through the cover, into the housing; do not tighten the
screws. Snug down the screws in an "X" sequence; i.e.: top left, then bottom righ� then top right, then bottom
left. Then fully tighten the screws in this same sequence.
14.2.3 Replacing Connectors: RITRON discourages the practice of removing and discarding the protective cap from
the connectors. Doing this may reduce the water-resistance of the unit. If you must remove a connector for any
reason, make sure it has been retightened properly -
"finger-tight" connector nuts
will
not provide an
effective water barrier.
14.2.4 Connecting the Antenna: Seal screws are used to secure the antenna to the housing. Always replace with a new
seal screw, not a common screw.
Do not remove the antenna connector from the housing; doing so win destroy the silicone rubber seal in the
interface. The screw securing the ground strap inside the housing must be fully tight.
14.2.5 If this device is to be used in a wet environment, use seal tape around the antenna connection. Use Archer
Connector Sealant, Radio Shack Number 278-1645 or an equivalent. Wrap the connection with the sealant tape
and press it securely in place.
