MAINTENANCE AND CLEANING INSTRUCTION

A. GENERAL

The times and the procedures for maintenance
and cleaning are given as guides and are not to be
construed as absolute or invariable. Cleaning
especially will vary depending upon local water
and ambient conditions and the ice volume
produced. Each ice machine must be maintained
individually, in accordance with its particular
location requirements.

B. Ice machine

The following maintenance should be scheduled at
least two times per year on these ice machines:

1. Check and clean the water line strainer or filter.

2. Remove the cover from the float reservoir – be
careful to not damage the two water sensors –and
depress the float to make sure that a full stream of
water enters the reservoir.

3. Check that the ice machine is level.

4. Check that the water level in the water reservoir
is below the overflow but high enough that it does
not run out of the spout opening.

NOTE: The float must stop the incoming water flow
when the rubber housed in the setting screw is
perpendicular to the water nozzle.

5. Clean the water system, water reservoir and the
interior of freezing cylinder using a solution of ice
machine cleaner. Refer to section C. CLEANING
INSTRUCTIONS OF WATER SYSTEM for
cleaning procedures and after cleaning will indicate
frequency and procedure to be followed in local
areas.

NOTE: Cleaning requirements vary according to
the local water conditions and individual user
operation.

6. If required, polish the two sensor rods secured
to the float reservoir cover. Heavy scale sediment
on them can be removed with the help of a bit of
ice machine cleaner plain.

7. With the ice machine and fan motor OFF clean
condenser using vacuum cleaner, whiskbroom or
non-metallic brush taking care to do not damage
the condenser temperature sensor.

8. Check for water leaks and tighten drain line
connections. Pour water into the sink to be sure
that drain line is open and clear.

9. Check the ice level control sensor to test
shut-off. Put your hand between the light source

and the receiver on the upper side of the storage
bin to cut off the light beam for at least 6 seconds.

This should cause the 1st RED LED on the front of
the PC board to turn off and, 6 seconds later the
ice machine will cease operation and the 6th
YELLOW LED will turn on. Once you remove your
hand the ice machine should resume normal
operation within a few seconds.

NOTE: The ice level control uses a device that
senses light, therefore they must be kept clean
enough so they can “see”.

Every month clean/wipe the sensing “eyes” with a
clean soft cloth.

10. Check for refrigerant leaks and for proper frost
line, approx. 8 inches from the compressor.

When in doubt of refrigerant charge, connect
refrigerant gauges to corresponding Schräder
valves and check for correct refrigerant pressures.
(See Operating Pressure on page 19 of this
manual).

11. Check that fan blades move freely and are not
touching any surfaces.

12. Remove the ice spout cover, loosen the bolt
securing the casting ice sweep and remove it; then
inspect the top bearing. Wipe away existing
grease and apply a coating of food grade
waterproof grease.

NOTE: Use of food-grade, waterproof grease to
lubricate the top bearing is recommended.

13. Turn the ice-dispensing spout and remove it.
Wash and sanitize it.

14. Remove the sink grill for washing and
sanitizing.
