Introduction

To the owner or user: This service manual is
intended to provide you, and the maintenance or
service technician, with the information needed to
install, start up, clean, maintain and repair this
product.

The SLE400 is an ice machine that produces
cubed ice on 6 vertical cube freezing surfaces.

When harvested, the cubes fall individually into the
ice storage bin. The SLE400 automatically
maintains the level of ice by turning on when the
ice level falls, and switches off when the bin is full.

The refrigeration system uses R-404A as the
refrigerant.
