SAFETY
The major safety factor associated with the Ultrafryer ZRT3-H Gas Fryer is burns from hot shortening. In order to pre-
vent serious burns, good houskeeping habits are required. The floor in front of and the area around the fryer should be kept
clean and dry. Whenever anything is placed in to a fryer vat, care should be used not to splash the hot shortening. Product
should always be “
PLACED”
into the shortening,
NOT THROWN.
Safety googles, neoprene insulated gloves and an apron
must be worn while filtering or boiling-out a fryer vat. Electrical controls on all Ultrafryer Fryers operate on 120 volts single
phase electrical power. No adjustments or replacement of electrical controls should ever be attempted without first disconneting
electrical power. The fryer should never be operated with wet hands or while standing in water. To do so can result in serious
electrical shock or death.
The Ultrafryer Model ZRT3-H is equipped with the following safety features:
1) High limit thermostat to shut off gas to the burners by opening a solenoid-actuated safety valve in the combination
gas control valve.
2) Combination gas control valve which includes a built-in pressure regulator and manual valve.
3) An air pressure switch to open the 24 volt electrical circuit to the combination gas control valve, turning gas to the
fryer
OFF,
should the Blower Motor fail.
4) Sensing circuit within the Spark Ignitor module to turn gas to the fryer
OFF
if a burner
FLAME OUT
occurs.
5) A Drain Valve Safety Switch and a Default-to-Off circuit in the Default-to-Manual-Restart (DTMR) Control that
will DISABLE the fryer each time the drain valve is
OPENED.
