I. INTRODUCTION

The Default-To-Manual-Restart (DTMR) Control is intended to reduce the possibility of “operator errors”
that can result in DRY FIRING a fryer, causing shortening to be scorched, heat mechanism damage, and/or
a vat re.

A. SAFETY - The DTMR operates on 24 volt single phase electrical power, and like other electrical
equipment, should not be operated with wet hands or while standing in water. Water should NEVER
be sprayed on or at the DTMR, as there is a danger of electrical shock and / or serious damage to its
electrical circuitry. Should the DTMR accidentally be sprayed with water, 1) IMMEDIATELY turn the
Power OFF at the Main Power Switch and 2) IMMEDIATELY contact a qualied service agent to
check the DTMR. The DTMR is located in close proximity to hot liquid shortening and care must be
taken to avoid serious burns. The oor in front of, and area around the fryer should be kept clean and
dry. Whenever anything is put into a cooking vat, care should be taken to not splash the hot shortening.
Products should always be “placed” into the shortening, not thrown.

B. SAFE CLEANING PROCEDURE - Before performing any cleaning routine, electrical power to the
DTMR should be turned OFF at the Main Power Switch. A SLIGHTLY dampened cloth may then be
used to clean any debris from the face of the DTMR. DO NOT USE any cleaners or de-greaser solvents
as they may mar the face or damage the internal circuitry of the control. Any questions regarding correct
cleaning procedures should be directed to the Ultrafryer Customer Service Department at
1-800-525-8130.

II. DEFAULT-TO-MANUAL-RESTART CONTROL
A. GENERAL

The Default-to-Manual-Restart (DTMR) Control along with an Electronic Thermostat is connected to a
fryer’s electrical system to control operation of the fryer. The DTMR contains a Default-to-Off
circuit that will DISABLE the fryer anytime the Drain Valve is OPEN, and a Default-to-Melt circuit
that will automatically place the fryer in a SHORTENING MELT MODE to gradually
and safely heat shortening each time the fryer’s Toggle HEAT/OFF Switch is turned to HEAT.

NOTE: On earlier fryer models, the Toggle HEAT/OFF
Switch may be labeled “COOK/FILTER.”

B. ELECTRONIC THERMOSTAT
The Electronic Thermostat has a temperature

range from 200ºF (93ºC) to 400ºF (204ºC).

C. DEFAULT-TO-MANUAL-RESTART CONTROL PANEL

1. BLUE “READY TO START” LAMP - When lit,

indicates the fryer’s Toggle HEAT/OFF switch
is in the HEAT position (or to “COOK” if the
switch is labeled “COOK/FILTER”), the Drain
Valve is CLOSED and the fryer is ready to be
placed in operation.

2. START BUTTON - When the button is
momentarily pressed, it places the fryer in melt
operation.

3. RED “STARTED” LAMP - When lit, indicates
the START BUTTON has been pressed, placing
the fryer in operation.

4. AMBER “MELT MODE” LAMP - When lit indicates the fryer is in the MELT MODE and that the timer
in the DTMR Default-to-Melt circuit is turning the fryer’s heat mechanism ON and OFF, as follows,
to heat the shortening gradually and safely.

TYPE FRYER

Electric 4 seconds 28 seconds

Gas (PAR 2) 8 seconds 28 seconds

Gas (PAR 3) 12 seconds 28 seconds

5. EXIT MELT BUTTON - When this button is momentarily pressed, the TIMER in the DTMR’s
Default-to-Melt circuit will switch to the FULL-ON position allowing the Electronic Thermostat

to heat shortening to its PRE-SET temperature.

6. AMBER “POWER” INDICATOR LAMP - When lit, indicates that electrical power to the fryer is on.

ON OFF

TIME

7. RED “BURNER” INDICATOR LAMP - When lit, indicates that the fryer’s heating mechanism is in

operation.

8. WHITE “READY TO COOK” INDICATOR LAMP - When lit, indicates that the preset temperature has
been reached and a cook cycle can be started.

ELECTRONIC THERMOSTAT CALIBRATION

PN 30A192 rev Apr2007 10

V Electronic Thermostat CALIBRATION - The Electronic Thermostat in all fryer congurations are equipped with
a Dial and Knob and should be checked and calibrated when necessary as follows:

A. Ensure electrical power and, if applicable, gas to the fryer has been turned OFF.

B. CAREFULLY drain sufcient shortening from the fryer to LOWER the shortening about 4” (102 mm) beneath
the Electronic Thermostat sensing probe.

C. After the sensing probe has COOLED, loop the bead of an ACCURATE digital test thermometer temperature
probe around the sensing element; then connect the probe to the thermometer.

D. Replace shortening drained in step B and ensure it is level with the shortening level mark on the rear of the
vat; then turn the power and, if applicable, gas to the fryer ON.

E. Set the KNOB of the Electronic Thermostat to the CENTER (300) of the dial and periodically STIR the shortening
in a COUNTER-CLOCKWISE (CCW) direction with a long handle skimmer to pull congealed shortening
UPWARD from the Cold Zone area.

F. When shortening has reached the set temperature and the RED indicator lamp on the fryer has turned OFF,
allow the Electronic Thermostat to cycle ON and OFF about ve (5) times to stablize the system.

G. After the shortening temperature has stablized, record the temperature reading of the TEST THERMOMETER
immediately after the RED indicator lamp and the fryer turns ON.

H. CAREFULLY loosen the set screw on the Electronic Thermostat KNOB without turning the thermostat potentiometer,
set the thermostat knob pointer to the temperature recorded by the test thermometer; then tighten the set screw on the
thermostat knob taking care not to turn the thermostat’s potentiometer.

I. Repeat steps A and B above, remove the test thermometer temperature probe from the Electronic Thermostat sensing
probe; then repeat step D to return the fryer to normal operation.
