INTRODUCTION

To the owner or user: The service manual you are

reading is intended to provide you, and the

maintenance or service technician, with the

information needed to install, start up, clean,

maintain, and service this ice system.

The ice machines covered in this manual are a

remote condenser type modular ice system that fits

a variety of Scotsman storage bins. They feature:

front service for the freezer, gear motor, control

box, water reservoir, and bin control; an electronic

circuit for monitoring ice and water level; a

thermostatic expansion valve; and R-404A as the

refrigerant.
