ER SERIES ELECTRIC FRYERS - GENERAL GENERAL INTRODUCTION This Service Manual covers specific service information related to the models listed on the front cover. Current production model fryers are built using a solid state control and computer control from Tridelta Industries (TDI). SINGLE FLOOR MODEL FRYERS Fryers with the Filter-Ready option installed, use the Mobile Filter. For service information related to the Mobile filter, refer to F24599 MOBILE FILTERS.
ER SERIES ELECTRIC FRYERS - GENERAL The fryer battery still utilizes many of the same components as the Vulcan ER series fryers. KLEENSCREEN FILTERING SYSTEM The Kleenscreen filtering system has been integrated into the ER Series fryer battery. The filter is housed in a pull-out drawer assembly at the base of the fryer. The filtering components in the drawer include a stainless steel filter tank, crumb-catch basket and a dual element mesh filter screen.

ER SERIES ELECTRIC FRYERS - ELECTRICAL OPERATION 2) SEQUENCE OF OPERATION Refer to schematic diagram 8810 for Cooking Control and Filtering System operation. 3. Cooking Control, Solid State or Computer FRY CYCLE - LIQUID SHORTENING R2 power relay coil and R2-2 N.O. contacts close. Cooking control powered at pin C2-1 (24VAC) and is jumpered to pin 6 (heat status). The control initializes and performs a diagnostic self check.
ER SERIES ELECTRIC FRYERS - ELECTRICAL OPERATION A. If shortening reaches 415°F or higher (1st high limit), the cooking control deactivates the heat demand and basket lift outputs, cooking timers are cancelled (if active), keypad is disabled, display indicates HI, and the electronic alarm will sound continuously. Turn power switch off to silence the alarm. Normal operation resumes when temperature drops below 415/F. B.
ER SERIES ELECTRIC FRYERS - ELECTRICAL OPERATION NOTE: If using solid shortening, when all filtered shortening is returned to the fry tank and filter power switch is off, open the filter drawer approximately one inch. Allow the remaining shortening in the line to drain into the filter tank to prevent possible clogging after the shortening cools and solidifies. Close the filter drawer when complete. 5. F. Pump motor circulates shortening through filter until power is removed. G.
