Upon receipt of the TMMG:
1. The float tube guide should be removed. It is
simply threaded onto the standpipe.
2. Remove the float tube and magnet from the
standpipe along with the cardboard.
3. Check the jam nut on the magnet end of the
tube to insure it is tight.
4. Insert the float tube through the float tube
guide. Be sure to maintain the proper
orientation.
5. Install the float tube and magnet back in the
standpipe.
6. Completely thread the float tube guide to
the standpipe. Tighten the setscrew.
If your TMMG utilizes a Penberthy float guide
system see steps 7 and 8. If not, go to step 9.
Penberthy recommends that either our guide
system or a stilling well be utilized to prevent
damage to the float tube.
7. Attach your float guide system by threading
it to the float tube guide until it will no
longer turn. Tighten the setscrew.
8. Insure that the float tube extends out of the
standpipe and into the float guide system.
9. Attach your float to the float tube via the
threaded stud on top of the float. A jam
nut has been provided to tighten this
connection.
Your TMMG is now ready to be installed in your
vessel.
