8. Check the ice level control sensor to test shut-
off. Put your hand between the light source
and the receiver so to cut off the light beam
for at least 10 seconds. This should cause the
immediate bin full condition with a bF1 on
display. The compressor stops immediately
and the gear reducer three minutes later.
Within few seconds from the removal of the
hand from between the sensor lights the ice
maker resume its operation with the standard
8 minutes of the start-up delay.
NOTE. The ice level control uses devices
that sense light, therefore they must be kept
clean enough so they can "see". Every month
clean/wipe the sensing "eyes" with a clean
soft cloth.
9. Check for refrigerant leaks and for proper
frost line, which should frost as far as approx.
20 cm (8") from the compressor. When
doubtful about refrigerant charge, install
refrigerant gauges on corresponding
Schräder valves and check for correct
refrigerant pressures.
(See Operating pressure at page 12 of this
manual).
10. Check that fan blades move freely and are
not touching any surfaces.
11. Turn the ice dispensing spout and remove it.
Wash and sanitize it as shown at point B
12. Remove the drip tray and grill for washing
and sanitizing as shown at point B.
E. CLEANING INSTRUCTIONS OF
WATER SYSTEM
1. Empty the ice storage bin trough the
dispensing button , then switch OFF the unit
from the green ON/OFF push button.
2. Remove the top panel and later the top cover
of storage bin.
3. Close the water shutoff valve on water line.
4. Remove the left side panel to gain access to
the water reservoir.
5. Remove the float reservoir cover and with a
piece of copper wire jump the two water level
sensors.
6. Switch ON the unit to purge and drain out all
water from the freezer.
CLEANING
7. Prepare the cleaning solution by diluting in a
plastic container two liters of warm water
(45°- 50°C) with a 0,2 liters of SCOTSMAN
Ice Machine Cleaner.
WARNING. The SCOTSMAN Ice Machine
Cleaner contains Phosphoric and
Hydroxyacetic acids. These compounds
are corrosive and may cause burns if
swallowed, DO NOT induce vomiting.
Give large amounts of water or milk. Call
Physician immediately. In case of external
contact flush with water. KEEP OUT OF
THE REACH OF CHILDREN
8. Pour the cleaning solution into the water
reservoir funnel till reaches the proper level.
9. After 15 minutes switch ON the Master switch
to start the unit.
10. Wait till the machine starts to discharge ice,
then continue to slowly pour the cleaning
solution into the water reservoir funnel taking
care to maintain the level just below the overf
low.
NOTE. The ice made with the cleaning
solution is slushy and colored also, it may
tend to loose fluidity creating some resistance
in being elevated and extruded; this situation
can be heard by the cracking noise made by
the ice. Should this occur it is recommended
to stop for few minutes the ice machine in
order to allow the ice in the freezer to partially
melt.
11. When all the cleaning solution has been
used, open the water shutoff valve to allow new
fresh water to flow into the reservoir. Let the unit
to continue to run until the ice resumes the
normal color and hardness.
12. Stop the icemaker and pour warm water on
the ice deposited into the storage bin to melt it up.
NOTE. DO NOT use ice produced with the
cleaning solution. Be sure none remains in
the bin.
SANITATION
13. Once completed the cleaning procedure
perform the monthly storage bin sanitizing
procedure as described at point (C).
NOTE. DO NOT use ice produced with the
sanitizing solution.
REMEMBER. To prevent the accumulation
of undesirable bacteria it is necessary to
sanitize the interior of the storage bin
with an anti-algae disinfectant solution
every once or at least twice a week.
