ERA & EBD SERIES ELECTRIC FRYERS - GENERAL
GENERAL
INTRODUCTION
This Service Manual covers specific service
information related to the models listed on the front
cover. ERA and EBD series electric fryers come
equipped with behind-the-door solid state controls.
The features and operation of the cooking controls
are the same for both single floor model fryers and
Kleenscreen battery fryers. All pictures and
illustrations are of a 2ER50AF (17kW, 208V) unless
otherwise noted.
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.
A GRO Frymate (dump station) can be configured in
a battery with fryers 15 1/2 inches or 21 inches in
width.

ERA & EBD SERIES ELECTRIC FRYERS - GENERAL
KLEENSCREEN FILTRATION
SYSTEM
The Kleenscreen filtration system is integrated into
the ERA & EBD 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. With
the filter drawer closed, a self-seating oil return line
provides the path to return the filtered shortening to
the fry tank.
This system is designed to provide a thorough and
easy method to filter the shortening.
Some of the benefits include:
• Self-contained system eliminating the use of
external filter equipment.
• Paperless filtering system.
• Easy to clean and low maintenance.
Kleenscreen fryer batteries are available in a
minimum of two and a maximum of four fryer
sections. The fryer size of each section is identical.
A GRO Frymate (dump station) can also be included
as one or more of the sections.
