C. ULTRASTAT 25 :
The Ultrastat 25 Cooking Computer is a high perform-
ance, micro-processor based electronic controller designed for use in com-
ercial appliance temperature and timing control applications. Utilizing a
microcontroller board, membrane switch front panel with a digital LED
readout, and display board, the Ultrastat 25 Cooking Computer has been
customized for Ultrafryer Systems applications by the addition of up to (10)
stage cooking profiles for each of the (8) product keys, exit melt feature,
optional temperature setback and filtering promps, and can be programmed
to cook products under “Flex” or “Straight” timing modes. Operation of the
Ultrastat 25 Cooking Computer is covered in its Instruction Manual PN
30A051 provided with Fryers Equipped with that computer.
INITIAL START-UP
A. CLEANING:
New units are wiped clean with solvents at the factory to remove any visible signs of dirt, oil, grease, etcetera, remaining
from the manufacturing process, then given a light coat of oil. Each fryer vessel should be thoroughly washed with hot soapy water to
remove film residues, installation dust or debris; and then wiped dry before being used for food preparation.
B. START-UP:
The fryers are tested, adjusted and calibrated prior to being shipped: however adjustments may be necessary on installation to
meet local conditions, high or low gas pressure, differences in altitudes, variations in gas characteristics and to correct possible problems
caused by rough handling or vibration during shipment. Initial calibration or adjustment is the responsibility of the customer and will not
be covered bythe Ultrafryer Systems warranty.
NOTE:
Calibration and adjustments must be performed by qualified personnel.
C. LIGHTING INSTRUCTIONS:
Each fryer is equipped with a spark ignition system and to test this system, perform the following steps,
in sequence:
1. Turn the Toggle
ON/OFF SWITCH
to the
OFF
position.
2. Fill the fryer vessel with hot or cold water to the
SHORTENING LEVEL
mark.
CAUTION : IF THE MAIN BURNERS ARE OPERATED WITH THE VESSEL EMPTY, THE HEAT WILL CAUSE THE JOINTS OF THE
FRYER VESSEL TO BE PLACED UNDER UNDO STRESS AND MAY CAUSE THE HEAT EXCHANGER VESSEL TO WARP OR
BUCKLE, VOIDING WARRANTY.
3. Turn the manual gas valve behind the fryer control access door of the fryer to the
OFF
position and wait
FIVE
(5) minutes for any
accumulated gas to disperse.
4.
ENSURE
the
MAIN
gas shut-off is in the
ON
position,
MANUAL VALVE
on the combination
GAS CONTROL VALVE
(located
behind the fryer control access door) is in the
ON
position and the
EXHAUST FAN
in
ON.
5. Turn the manual gas valve to the
ON
position.
6. Turn the
ON/OFF
switch
ON
; then place the
DTMR
or
ULTRASTAT
Cooking Computer into the
MELT MODE
.
WARNING!!! DO NOT USE A MATCH OR CANDLE TO LIGHT A FRYER… EVER!
SEQUENCE OF IGNITION:
When the lighting instruction steps are performed in the sequence listed above, the following will occur:
A. Blower motor will come
ON
activating the air pressure switch.
B. The air pressure switch will
CLOSE
completing the electrical circuit to the transformer.
C. The transformer will supply 24 volts to the
IGNITOR MODULE
and
GAS CONTROL VALVE
, and the ignitor will
SPARK
lighting
the gas in the burner.
WARNING!!! WHEN CHECKING FOR BURNER PERFORMANCE, DO NOT STAND WITH YOUR FACE CLOSE
TO THE BURNER…. IT MAY LIGHT WITH A “POP” AND COULD FLASH BACK AND CAUSE FACIAL BURNS.
NOTES:
1) If the burner flame fails, it will be sensed by the SPARK IGNITOR, the Spark Ignitor Module will open the electrical circuit to the
GAS CONTROL VALVE
shutting off gas to the burner. 2) If the blower motor fails, the air pressure switch will open the
electrical circuit to the
TRANSFORMER
removing electrical power from the SPARK IGNITOR MODULE and GAS CONTROL VALVE
shutting off gas to the burner.
BURNER OPERATION TEST:
Perform above
LIGHTING INSTRUCTIONS
and observe operation of the burners. When satisfied that the
burner is operating properly, drain the fryer vessel of water and dry the vessel thoroughly; then fill the fryer vessel with shortening according to
instruction below.
SHORTENING INSTALLATION:
A. LIQUID SHORTENING:
When using a liquid shortening cooking oil) fill the fryer with shortening even with the middle line of the
“E ”
in the word LEVEL of the applicable shortening level mark on he rear wall of the fryer.
B. SOLID SHORTENING:
1) Cut a block of solid shortening into small pieces.
2) Place small pieces of solid shortening
EVENLY
on top of the
HEAT EXCHANGER TUBES
or
THOROUGHLY PACK
these
pieces of solid shortening between, below and above the
EAT EXCHANGER TUBES
. While packing solid shortening is messy
and time consuming, it is the fastest way to melt solid shortening.
