3. Thread the calibrated test gauge fixture into
the existing t-fitting. Seal the threads with pipe
thread sealant.
You may have to slightly adjust
the t-fitting by pulling it toward the front of the
fryer with an adjustable wrench to thread in the
test fixture (figure. 4).
4. Thread the existing pressure gauge into the
test fixture T-fitting. Seal the threads with pipe
thread sealant.
Note! -
During the test procedure, use the
calibrated test gauge to collect measurement
data for the inspection form. Also monitor the
existing pressure gauge from the fryer to make
sure that it is functioning within a similar range
to the gauge of the test fixture. If no function
from the existing gauge, a sticking gauge, or one
that does not indicate zero when no pressure in
the fryer, it will need to be replaced with a new
gauge #16910 after the test. (figure. 4).
