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 AFE424 is an ice machine that produces
flaked ice and stores it in a insulated bin. It
automatically maintains the level of ice by turning
on when the ice level falls and switches off when it
is full.

This unit in serviceable in place; the ice storage bin
and hood may be removed from the chassis to
allow service access without removing the ice
machine from its installed location. The
refrigeration system uses R-134a as the
refrigerant.

The ice machine must be installed indoors in a
controlled environment.

AIR OUT
Operating the ice machine outside of the above
limitations, or outdoors, is potentially damaging to
the machine, and it is misuse of the machine. This
may void the warranty.

AIR IN
Airflow on air cooled models:
·
Intake through the right grill.
·
Exhaust from the left grill.
Do not install where this air flow is blocked.
The AFE424 has a removable cabinet. When
installed, the machine should have some extra
clearance (1/8") on the left and right sides so that
the cabinet may be easily removed when the
machine is in place.

Installation
Water
The water supply for this ice machine has been in
contact with many materials since it fell from the
sky as rain. All rain is slightly acidic, and tends to
dissolve the materials it comes in contact with.
During water’s journey to the ice machine, it has
flowed over and through the ground, been picked
up by a municipal or private pump, forced through
a series of pipes of differing construction and may
have been treated by the municipality providing the
water.
The water supplied to this ice machine will then
contain a variety of substances that will likely show
up as solids during the ice making process. These
solids are similar to those found when water is
boiled out of a saucepan. Only the water boils
away, and the minerals that were in the water
solidify in the pan. During ice making the water is
frozen into ice, and many of the minerals stay
behind in the ice machine water system. After time
the minerals will have to be dissolved by ice
machine cleaner, then flushed away during the
cleaning process.
An ice machine is a food manufacturing plant; it
takes a raw material, in this case water, and
transforms it into a food product, ice. The purity of
the water is very important in obtaining pure ice
and in maximizing product life.
The water to the ice machine should be filtered.
Water filters vary greatly in ability and function.
Install one that filters out suspended solids The
finer the filter the better, but finer filters may
plug-up sooner than course ones. It may be
necessary to add a course filter ahead of the fine
filter to prolong filter life.
This ice machine may be installed in the open or
under a counter. No clearance is required at the
sides or top beyond what’s needed to place the
cabinet into position. Air cooled models blow air in
and out through the grills at the front. Space is
required for utility connections at the back.
The ice machine is not designed for outdoor
use. It must be installed indoors, in a controlled
environment. The air and water temperatures
must not exceed rated limits.
Electrical power is supplied through a cord
connected to the unit. All local codes must be
followed.
Pre-installation:
1. Inspect the place where the ice machine is to be
installed. Check for:
space for the cabinet
·
water supply,
·
drain availability
·
and electrical power supply.
·
No extension cords are allowed. The building drain
inlet must be lower than the drain outlet(s) at the
back of the ice machine. The water supply must
have a hand shut off valve accessible when the
unit is installed.
2. Determine the method of installation, is the
machine to be installed under the counter? Is the
drain in the floor under the machine? Is the water
inlet accessible from the top?
Have the water tested. Either acidic water or
alkaline water will cause corrosion. Dissolved
solids cannot be filtered out. Check with a water
treatment specialist regarding testing, treatment
and filters.
Note: Deionized water is not recommended due
to its potential corrosive nature and any
damage caused by DI water will not be covered
by the warranty.
