11. Depending on the cook load selected, pressure will release somewhere between the last one to two minutes
of the cook load. As pressure releases, verify the pressure (as viewed on the pressure gauge) when the
lid locking pin fully disengages the lid handle. To do this, use a business card and try to repeatedly slide this
between the locking block and the right side of the lid handle locking weldment (figure 8). Once you are able
to fully slide the business card between these two components (figure 9), immediately note the pressure from
the calibrated test gauge. This is the point when the lid is unlocked.
12. If this pressure was less than 1.7psi (figure 10) this lid passes inspection. Move to step 13. If the pressure
when the lid locking pin disengages was greater than 1.7 psi, stop. Take the fryer out of service until the lid
assembly can be replaced (lid assembly part number listed on page 5). Record your results in the inspection
form.
Note! - If pressure does not drop below 1.7psi when the timer reaches 0:00, wait for all pressure to release from
the fry pot, then make sure the pressure solenoid is working freely and unobstructed as well as all related
pressure release plumbing.
13. Have the store remove the product from the fryer.
14. Re-install the lid cover.
15. Remove Existing Pressure gauge from the test
fixture and then remove the test fixture from the
fryer. (figure. 4)
16. Replace the reducer in the T-fitting and re-install
the existing pressure gauge if it passed inspec-
tion. Otherwise replace with #16910. Seal
threads with pipe thread sealant.
