14. Make sure there is sufficient slack tape inside the tank to allow float travel to the tank bot-
tom (check reference mark previously made). Trim the tape about 6 feet (1.8 M) from the
bottom of the gauge head.
15. Proceed per instructions in section , Install Tape in the Gauge Head, on page 35 depending
on the model.
16. Make a hand gauge measurement of the tank product level. Use the bench mark reference
to calibrate the hand gauge. Use extra care to make certain that this measurement is accu-
rate, because the accuracy of the automatic gauge depends upon it.
17. Refer to appropriate tank configuration to reset the gauge, then use the hand gauge mea-
surement to set the current product level.
Note To fill the counter assembly side of the gauge head with oil, it is necessary to
change the bottom NPT condensate drain plug. Replace it with a solid 1/4”-NPT plug or
reverse the top solid plug with the bottom plug. Fill the hole in the condensate drain plug
with RTV 737 sealant.
