Drain Plumbing

Your ice machine uses a gravity drain, (figure 1)
that requires 5/8" I.D. tubing from the back of the
ice machine to a plumbed connection to a sanitary
sewer. Remove the access panel to plumb in drain
connection. Gravity drain location for built-in units
can be within the area shown in figure 3. An option­al drain pump, (figure 2) can be purchased for your
ice machine if a gravity drain is not accessible.

OBSERVE AND FOLLOW ALL LOCAL CODES
WHEN INSTALLING ICE MACHINE.

Water Supply

This ice machine must be connected to a potable,
active cold water supply line delivering water
pressure at a minimum of 20 psi and maximum of
120 psi.

• Water connection is made through a right angle
garden hose fitting. See garden hose fitting for
detailed instruction sheet.

• A water filter is recommended for this unit. A
quality filter can remove particles as well as
remove taste and odors from water. Do not use
any thread sealers.

• Softened water is not recommended. This will
produce mushy, cloudy ice cubes that will stick
together.

• De-ionized water is not recommended. This
water will not form solid ice cubes.

• Awater specialist can recommend proper water
treatment.

• After installation of water line, turn on water and
check for any leaks. Additional tightening may be
needed.

• Allow for extra water line for built-in installations
for easy removal of unit and to help prevent the
water line from kinking.

Operation

Your ice machine is unique in forming ice. It uses
fractional freezing to form a slab of ice that is clear
and has less mineral content than the water it is
produced from. This is accomplished by running
water over the cold evaporator plate which gradu­ally freezes the water to produce the ice slab. Min­eral deposits are left in the reservoir.

When the ice slab reaches the correct thickness
determined by the temperature of the evaporator
plate, the electronic control switches to the har­vest cycle to harvest the ice. During the harvest
cycle, the ice slab falls from the evaporator to the
ice grid cutter. Here, the ice slab is cut into 3/4"
squares by the grid cutter's heated wires. During
the harvest cycle, the drain valve will remain open

for 45 seconds to drain the reservoir of remaining
deposits. After that, the water valve open will open
for 2 minutes providing 2 quarts of water to the
reservoir for the next ice production cycle.

The ice machine will keep producing ice until the
ice machine's bin is full and will restart automati­cally when ice needs to be replenished in the bin.

Help Prevent Tragedies

Each year, children die because they climb inside
a discarded refrigeration product, get trapped
inside and suffocate. Take precautions to prevent
such tragedies by removing the door, taping or
chaining it shut before discarding.

Cleaning Your Ice machine

Some impurities will remain and build-up in the ice
machine and stick to the ice machine's parts over
time. This build-up must be removed for proper ice
production, ice quality, and ice machine life. Your
ice machine is equipped with a cleaning mode that
will help in cleaning out these impurities.

The impurities will regularly (at the very least,
annually) need to be cleaned of this build-up,
depending on use and water hardness. You can
use an acid such as one specified for ice machine
cleaning or you can use citric acid to remove the
build-up. To clean the ice machine:

1. Switch the selector switch to the "OFF"
position.

2. Remove the drain plug at the bottom of the
reservoir to drain any remaining water and
then reinstall.

3. Add the recommend cleaner solution to the
reservoir of the ice machine. Access to the
reservoir can be obtained by removing the
front panel screws and the front panel.
Determine to proper amount of cleaner from
the ice machine cleaner manufacturer's mix­ture ratio based on 3 quarts of water (refer
to manufacturer's directions).

4. Replace the front cover panel and close the
door.

5. Switch the selector switch on the grille of the
ice machine the clean position. Three quarts
of water will automatically be added to the
cleaning solution.

6. The total cleaning time will end in 49 min­utes. The cleaning cycle will automatically
rinse the evaporator plate and also drain the
cleaning solution and rinse water.

7. After the cleaning cycle has ended, remove
the front panel again and check that the
build up has been removed. The evaporator
plate should be clean, shiny, and smooth to
the touch. If build up is still visible, repeat
the cleaning cycle above. If build up is
removed, continue below.

8. Remove the distributor tube, hose clamp,
hose and its rubber ends.

9. Thoroughly clean the inside of the distribu­tor tube and the spray holes. You can use
the same cleaning solution as before and an
old toothbrush to reach the inside of the dis­tributor tube.

10. Reinstall the rubber ends, hose, and hose
clamp to the distributor and then reinstall the
distributor tube to the evaporator with the
spray holes pointed to the bottom of the
evaporator plate. Reinstall the front cover
panel with the two front panel screws.

11. Clean the ice machine's interior, ice scoop,
interior door panel and door gasket with mild
soap and water. Using two tablespoons of
baking soda in one quart of warm water
while cleaning will help remove odors. Rinse
with fresh water. Do not use any abrasive
cleaning products.

Your ice machine is now clean and sanitized and
may be put back into operation by switching the
selector witch to the "ON" position.

THINGS TO REMEMBER

Things to Remember

• Allow your ice machine to run for 24-48 hours to
accumulate ice in ice machine's bin.

• Unit will cycle often between ice production and
ice harvest cycles.

• Your unit will automatically shut down when the
ice bin is full.

• Unplug your ice machine before working on
unit.

• Keep your ice machine clean for proper ice
quality, production, and unit life.

• Room and water temperatures will greatly
affect the output of ice in your unit (see table).
Ice will also melt away, especially at the start
of an empty bin, but will slow down as ice
accumulates.
