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.

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.

• On 208VAC and 240VAC models, a transformer provides power for the fryer controls and drawer filter system controls.

• On 480VAC models, a 120VAC connection is required for each fryer section.

TOOLS

Standard

• Standard set of hand tools.

• VOM with A/C current tester (any quality VOM with a sensitivity of at least 20,000 ohms per volt can be used).

• Digital Temperature tester (thermocouple type).

Special

• Field service grounding kit (available locally).

• Burndy pin extraction tool RX2025 GE1; Newark Electronics Catalog Number 16F6666. Used for removing pin terminals on Burndy connectors.

• Clamp on type amp meter.

A GRO Frymate (dump station) can also be included as one or more of the sections.
