8. LEVELING
If legs are used, adjust the leveling legs of the storage bin until the
unit
is level and all
four (4) legs are insolid Gontact with the floor.
Leveling is very important to obtain proper dralning and to maintain the
proper level
in the water pan of the ice tuber*.
NOTE: If the bin is to be installed flush to the floor, the machine must
be sealed to the floor with an approved mastic such *as .Sears #3803-0 Caulk,
Dow R.T.V. 101, 102 or G. E. 731, 732. This.1~an N.S.F. requirement and
is the responsibility of the installer.
C. UNIT LOCATION
1.
Allow at least a minimum of six (6) inches at the rear and side of the
ice machine for proper air circulation.
This unit has been designed to be installed
in an indoor location which
is clean and which can be adequately ventilated; the
air and water
temperatures should never exceed 100 degrees nor fall below
50 degrees.
(Temperatures above 100 degrees
will cut the ice making capacity below
an economical level; temperatures below 50 degrees will cause a
malfunction of thenostatic sensors.

D. UNIT SET-UP
1.
Take off front panel of machine and remove hardware bag or service
manual envelope with the water strainer enclosed.
2.
Mount the ice maker to the top of the ice storage bin or adapter in
the proper position over the ice drop opening. The ice maker must
then be sealed both on the outside and the inside bottom edges with
an approved

J. STARTING THE UNIT
After the ice cuber has been unpacked and leveled and all plumbing and
electrical connections have been made, start the
unit and check for proper
operation.
A cuber has three separate circuits:
A. The water circuit
B. The refrigerant circuit
C. The electrical circuit
1. Start checking the water circuit by making sure that there are no thread
or flare joint leaks, either outside the unit or inthe compressor section.
Next check the water flow over the evaporator and make sure that all holes
in the water distributor are open, and that there- is no undue splash or
loss of water into the ice bin.
Also check to see
if the float valve is functioning properly and the
correct water level is being maintained. Re-adjust
if necessary.
Check the refrigerant circuit by making sure that the condenser fan is
running.
(Feel the casing for vibration.)
2.
(This will be evident by air noise.)
Is the compressor running?
Is the evaporator getting cold?
3- Check bin-harvest switch operation. (See proceedure in manual)

SANITIZING AND CLEANING PROCEDURE
1.
Remove front panel to gain access to the on-off-clean switch.
2.
Push switch to "clean" and allow the ice on the evaporator to
release or melt away.
3. Remove all ice from storage bin.
4. If lime scale is present add 2 oz. of "Lime-A-Wayn or Yalgon
Nickel-Safe Ice Machine Cleaner" directly into water reservoir.
Circulate for no longer than
15 minutes. Go to Step 7 to flush
out the system before going to Step 5.
CAUTION: All ice machine cleaner must be flushed
out of the system before the sanitmg solution
is used
in Step 5. The reaction of the two
chemicals can cause hazardous gases to be
generated.
5.
Pour
1/2 02. of household bleach into the water reservoir and
circulate for 15 minutes to sanitize the circulating water system
including the evaporator,
pump, distributor and a1 1 interconnecting
vinyl tubing.
Go to Step 7 to flush out.
Mix a sanitizing solution of
1 oz. household bleach to one gallon
of water. Using
a non-metallic bristle brush, scrub the following:

Make sure splash curtain is correctly positioned.
7.
Depress dump valve switch on top of control box and allow cleaner
or sanitizer to
drain away. Allow float valve to fill reservoir
with clean fresh water, circulate for apporximately
1 minute.
Depress
dump valve switch and allow water to drain away.
Repeat

WATER TREATMENT
Automatic ice-making machines can quit working for any number of reasons,
mechanical, electrical or faulty refrigeration, but
water problems foul them
UP faster than almost anything elsq. While ice machines vary In design, you
can apply these water treatment tips to
all of them.
1. START WITH THE WATER
The mineral content of water .varips in diffewnt areas and as the
chart shows, high hardness and alkalinity counts combine to
form
insoluble calcium carbonate or lime scale. If this condition is
constant, the intake water must be treated constantly to prevent
scale formation
in the ice machine.
2.
3.
4.
PREVENT LIME SCALE FORMATION
<

incoming water line.
with a capacity of 400-450 lbs. per day. Fill the feeder with 6R
Hicromet, the
slowly soluble poly-phosphate which lasts six months
before renewing the
8-02. charge.
Constant treatment
with 6R Micromet will control lime scale and
prevent minerals from sticking to the freezing surfaces in ice
machines. Result
- smooth movement of ice slabs, good harvest of
ice cubes, efficient, automatic production.

REMOVE OBJECTIONABLE TASTE OR ODOR
If the bad taste or odor is traceable to the water source, install a
Calgon Fine Carbon Filter to the incoming water line.
Fine Carbon Filter is ideal
for machines making up to 500 pounds of
ice per day and will remove bad taste, odors, and problems caused
by chlorine in the water supply.
