FBR18 & FBRA18 SERIES GAS RETHERMALIZERS

CHAPTER 3: OPERATING INSTRUCTIONS

3.1Introduction

Mechanically, the FBR18 and FBRA18 rethermalizers are virtually identical, the only difference being that the FBRA18 units have an automatic filling (AutoFill) feature. Both units use the same digital temperature controller and mechanical timers.

In operation, a setpoint is programmed into the controller which then regulates burner firing to maintain the water in the cookpot at the desired temperature. Six individual color-coded mechani- cal timers allow different types or quantities of product to be rethermalized simultaneously. The timers are equipped with an alarm to notify the operator that rethermalizing is complete. The prod- uct baskets have color-coded handles that correspond to the timers to eliminate confusion.
