This appliance is intended for commercial use in kitchens of restaurants, bakeries,
hospitals, etc. but not for the continuous mass production of food such as in a factory
setting. During use the units airborne A-weighted emission sound pressure is below
70 db(A). All repairs must be performed by the manufacturer, its service agent or
similarly qualified persons in order to avoid a hazard.
Always use strain relief. The provided power cord must be installed with a strain relief
in a way that if the strain relief fails, wires L1, L2, L3 and N must draw taunt and fail
first. If the supplied power cord or an existing one becomes damaged, do not use it;
rather, replace it with a known good power cord. The powercord must be replaced by
the manufacturer, its service agent or similarly qualified persons in order to avoid a
hazard.
Proper daily, weekly, monthly, quarterly and yearly maintenance must be performed
on this appliance to ensure safe and continuous operation. This appliance must never
be cleaned with a water jet or steam cleaning tool. Cleaning brushes are shipped with
the appliance and proper cleaning instructions are included in this manual.
Proper maintenance also increases the usable life of the appliance and oil, which
reduces lifetime operating costs. Additionally, old oil increases the possibility of surge
boiling and fire due to the reduced flash point of the oil. The oil temperature must
never exceed 450° F (230°C).

Preface
vii
This appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge, unless
they have been given supervision or instruction concerning use of the appliance by a
person responsible for their safety. Children should be supervised to ensure that they
do not play with the appliance.
This appliance is not intended to be operated by means of an external timer or a
separate remote control system.

T-25 ANALOG CHANNELS This test mode is available to display the current low-
level analog status of any of the analog inputs on the
primary Analog to Digital converter chip inside the
control.
T-26 HEAT CTRL This test mode has very specialized and very limited
use. It displays information about the heating algorithm
and its performance, and can be useful when tuning
the heating algorithm for a brand new fryer type.

not used, the control cycles the pressure solenoid on
and off. This keeps the solenoid from getting gummed
up and sticking. This cycling at the end of a cook cycle
occurs only for cook cycles which haven't just used the
pressure solenoid. Generally it is used for open fried
products being cooked in a pressure fryer.
T-31 BLOCKED DRAIN
AUTO-REV RETRIES
The control gets a feedback signal from the motorized
drain valve when it is at the fully open and fully closed
positions. If the control is commanding the drain valve
to close, but it doesn’t see the closed feedback signal
within a reasonable time, it presumes that maybe a
brush has been left in the open drain valve and that is
preventing the valve from closing. In response, the
control automatically opens the drain valve back up,
sounds a sequence of fast beeps, and displays Drain
Blocked for a few seconds, giving the user time to re-
move the brush. After a short delay, the control auto-
matically tries to close the drain valve again.
T-32 ATO DELTA: -FULL- The auto-topoff (ATO) oil level detection system moni-
tors the temperature difference between the main
probe (just above the heating elements) and the level
probe (located at the desired oil fill level). In static, non-
cooking situations, the level probe, high in the pot, is
generally cooler than the main probe, even when the
pot is properly filled and both probes are immersed in
the oil (the oil at the top of the pot radiates a lot of its
heat, and conducts heat away, into the air).
T-33 ATO DELTA: -LOW- The auto-topoff (ATO) oil level detection system moni-
tors the temperature difference between the main
probe (just above the heating elements) and the level
probe (located at the desired oil fill level). In static non-
cooking situations, the level probe high in the pot is
generally cooler than the main probe even when the
pot is properly filled and both are immersed in the oil.
T-34 QUICK FLTR: FILL TO
LVL PROBE - TEMP
RISE
When refilling the pot after a filter operation, the control
monitors the upper temperature probe (the level probe,
at the oil fill line) and looks for a temperature rise there
that indicates the oil has refilled high enough to reach
or splash on that probe.
T-35 DAILY+POL: FILL TO

T-36 ANY FILL: LVL PROBE
MIN DETECT
How the control monitors the level probe for a tempera-
ture rise when refilling the pot is described in the de-
tails of step T-34. This T-36 parameter specifies a
minimum reasonable filling time for that temperature
rise to be trusted.
T-37 CHANGE TECH CODE The default Tech Mode password can be changed by
the user. This password is used for entry to Tech Mode
and Stats Mode. It is recommended that this password
not be changed except under extreme circumstances,
as a service technician visiting the store to service the
fryer would probably not know the new password and
would not be able to access Tech Mode.

initialize the control board.
T-39 HEAT PULSE ENABLED Always displays YES, and is not changeable.
T-40 PROTECTION PROBE Manually turn on the protection probe feature. Must up-
grade software to v1.60 to use this feature. For soft-
ware v1.60 and after, the control auto-detects whether
the probe is connected when the fryer enters the melt
cycle for the first time and sees the probe 50°F hotter
than the main temp probe.

Foaming or boiling
over.
Some customers choose not
to use oil stabilizers which
can cause foaming and boil-
over.
Product with excessive ice crystals
should be dipped once quickly then
removed from the fryer to allow ice
crystals to melt and excessive water
to evaporate. Then place the product
back into the fryer and cook
normally.
See boil-over chart on fryer
and Boil-Over Prevention
section of Operator’s Manual.
Refer to 2.7 Boil-Over Prevention in

In the event of a system failure the control board displays an error message. These
messages are coded as E which represents an error, a number designation and error
message, such as E-4 CPU TO HOT. Also, a constant tone sounds. To silence the
tone, press any of the product buttons. Use the following table to interpret and correct
an error code.

E-10 High limit tripped
(Software prior to
version 1.60).
Check the error log to find out the vat temperature at
the time the high limit tripped. If this temperature was
very low, this may be a sign that the vat was turned on
with low or no oil. If this was the case, fill the pot with
oil and reset the high limit. If the trip temperature was
several degrees above the oil setpoint temperature,
test for a sticking contactor and replace if faulty. If the
high limit tripped at an oil temperature, inspect the high
limit thermocouples for carbon build up and clean if ne-
cessary. If no carbon found, see 8.12
