Frymaster EH1721 Installation & Operation Manual page 10

a. Emergency Cutoff System: Be sure that each fryer is connected to a dedicated set of contacts in an
emergency cutoff system.
1. Do not attempt to connect the contacts in series.
2. Do not connect more than one fryer to each set of contacts.
3. The contacts must be normally closed contacts that open during the emergency.
4. Do not apply external voltage to the contacts.
3.5 OPERATING SWITCHES:
a. Fryer/Filter Switches: This fryer/filter system is equipped with drain valve safety switches on the
two batteried fryers to de-energize the fryer heating elements during the filter process. This is for
additional safety. You should always turn the fryer power switch "OFF" prior to filtering.
1. Fryer Power Switch: Located on the right-hand side of the computer. It transfers the power from the
computer to that individual fryer's heating element
circuits.
2. Pump Power Switch: Located on the right fryer cabinet
control panel of the fryer battery. It operates the Super
Cascade filter pump motor.
3. Drain Valve Micro-switch: The computer will display
"HELP" when the drain valve is opened. The computer
will lockout and prevent any cooking operation until
"EXIT/COOL FILTER" is pressed.
4. Float Switch: Located in the frypot. Designed as a safety
switch, it prevents the computer from calling for heat until
the oil level extends above the heating elements.
