CHAPTER 6 - 808-P2 INSTALLATION GUIDE

1. Pick a spot in the tank for the sender bar to be mounted. It should
be as close to the middle of the tank as possible. Allow room for the
head at the top of the sender bar. Make sure that the float will not
contact any baffles or other obstructions in the tank. It is preferable if
the float can be accessed from the hatch, to make any future service
work easier. For this reason do not mount the float behind a baffle
where it can't be reached from the hatch.
2. Drill or cut a hole in the top of the tank to mount a 1 inch NPT coupler
(not provided). Weld the top coupler in place.
3. Slide the compression fitting over the sender bar, threads facing
down, and insert the bar through the coupler and align it vertically in
the tank. Determine how much length needs to be cut off the bottom
of the bar. At a minimum the bar should be mounted 1 inch off the
bottom of the tank to allow for tank expansion and contraction. For
tanks greater than 75 inches in height, increase the gap to 1.5 inches.
Cut the bar with a hack saw and trim exposed circuit board with a sharp
knife. Do not use a disk type cutoff saw since the heat generated
will short circuit the internal circuit board.
4. Ensure that the compression fitting is on the bar and clean the end
of the bar and the inside of the end cap with Loctite 7070 Cleaner.
Spray Loctite T7471 Primer onto both the end of the bar and the inside
of the end cap. Allow the primer to dry for a few minutes. Apply a
bead of Loctite 680 Retaining Compound around the bottom of the
tube and around the top of the end cap. Place the cap onto the end
of the tube with a twisting motion so that the retaining compound
is smeared completely on the portion of the bar where the end cap
is. To remove entrapped air, place the end on the floor and rock the
bar until excess air has escaped. Keep the end cap in position by
gently clamping the bar in a vise with the end against a solid object.
Avoid setting the end cap against a cold floor, as this will slow the
curing process. The curing time should be about an hour at room
temperature.
CAUTION: The Loctite must be set before the tank is put into
W
service. Bar failure due to a leaking end cap is NOT covered by
warranty.
Note that a kit with all the required Loctite products is available from
Garnet. For further details on the Loctite products see Technical
Service Bulletin #17 on our web site, www.garnetinstruments.com.
