6. Visually inspect the pressure pin, lid lock
assembly and lid handle weldment for any
broken or missing parts (Fig. 2 & 6). If
any of the afore mentioned are true, stop.
Take the fryer out of service until a new lid
assembly can be installed. For the lid part
number, see page 5.
7. Next, visually inspect for oil migrating into
the top of the lid through the lid lock assem-
bly or vent holes. If either of these are true,
this fryer will not pass inspection and the lid
will need to be replaced ASAP. The store
however will be able to temporarily con-
tinue to use this lid as long as it passes the
pressure pin engagement / disengagement
procedure.
8. Clean and lube the pressure pin, locking
pins and linkage with spindle lube (compo-
nents shown in Figure. 2.).
9. Have the store bread and cook either a 4,
6, or 8-head load of Original Recipe in the
pressure fryer and start the appropriate
timer. The lid handle should be fully in the
locked position during this test.
As pressure builds, the locking pins
will engage the lid handle weldment.
(Direction indicated by the arrow.)
10. Once the calibrated test gauge reads greater than 3psi (figure 10), check to make sure the locking pin is
engaged in the lid handle weldment. To do this, insert a business card where indicated by the red dotted line
in figure 7. If the business card will not slide between the right side of the lid handle weldment and the locking
block, then the pin is engaged and the lid handle is locked (Figure 8). If you are able to slide the business
card between the right side of the lid handle weldment and the locking block, then the lid handle is unlocked
(figure 9). STOP! Take this fryer out of service until a new lid assembly is installed and do not open the lid
until the pressure gauge reads zero psi (lid part numbers listed on page 5.).
Note! - If pressure exceeds 12psi during the test, wait until all pressure safely exhausts from the fry pot and then
make sure the deadweight is clean and free from obstruction as well as all associated plumbing.
