DATAFLOW RTU

14.1.2 Optional mounting bracket OMEGA part number RTU-25104600 is available for DATAFLOW 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.

14.2 Reassembling DATAFLOW RTU 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 Omega: Part

No. RTU-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 right, then top right, then bottom

left. Then fully tighten the screws in this same sequence.

14.2.3 Replacing Connectors: OMEGA 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 will 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.
