1. With the "ICE-OFF-WASH" switch in the center (OFF) position, turn on supply
water and power.
2. Pour about one liter of potable water into the circulation system to lubricate the
pump seal.
3. Move the "ICE-OFF-WASH" switch to the right (WASH) position and observe
the water fill cycle and the pump running. Water fill is complete when the water
in the liquid level control tube reaches the high-level probe. At this time
observe that the water shuts off and that there are no water leaks.
4. Pull the right end of the water plate down, stretching the springs until the pump
stops, and hold until the pump does not re-start when released. The water plate
will open fully to dump the batch of water, then close immediately. The water
plate should stop when it is fully closed, and the water fill cycle will repeat.
5. After the water fill is complete move the "ICE-OFF-WASH" switch to the left
(ICE) position and observe that the compressor (and fan in "A" models) starts,
and the water pump continues to run.
6. Test the bin thermostat by holding some ice against the capillary tube. If
necessary, adjust the thermostat so that the ice maker shuts off within 30
seconds after ice contacts the capillary tube.
7. Be sure that the drain pan/ice chute is in place, and that the electrical control
box cover is secured, then replace the cabinet panels. Start with the SIDE
panels, then the FRONT panel. Secure the FRONT panel with (2) screws along

the bottom edge, replace the TOP panel, and finally secure all the panels with
(2) screws in the TOP-SIDES of the machine.
8. Discard ice from start-up cycles, then clean and sanitize the bin following the
instructions provided with the bin.
9. Leave this manual with the owner/user. Emphasize the "CAUTION: RISK OF
PERSONAL INJURY..." NOTICE ON THE FIRST PAGE, and the importance of
the PREVENTATIVE MAINTENANCE recommendations below.
PREVENTATIVE MAINTENANCE
CLEANING: 3 to 6 month intervals, depending on water conditions.
INSPECTIONS: During cleaning - at least twice a year.
SERVICE: All such equipment will require service at some time. Service requirements
will be minimized with faithful preventative maintenance including good housekeeping
at the installation site. A CALL FOR SERVICE AS SOON AS A POSSIBLE
PROBLEM IS NOTICED MAY AVOID EXTENSIVE REPAIRS.

CAUTION:
RISK OF PERSONAL INJURY OR PROPERTY DAMAGE.
Do not use ammonia solutions in cleaning any part of the ice maker.
Do not mix ice machine cleaner and sanitizer together.
Use rubber gloves, eye protection, and an apron.
Clean up splashes or spillage immediately.
Follow these instructions exactly.
1. Mix 1/2 bag of KOLD-DRAFT ice machine cleaner (55R-01000) in one (1) liter
of clean, warm water (82°C. MAX.).
2. If the cuber is operating, wait until a harvest cycle occurs then trip the
"ICE-OFF-WASH" switch to "WASH" as soon as the water plate begins to close.
3. Empty all ice from the storage bin and shut off other ice makers on the same
bin.
4. After the water fill is completed, switch the "ICE-OFF-WASH" to "OFF". While
pinching water level control hose, carefully remove the water level control tube
from the cap. HOLD THE TUBE HIGH ENOUGH SO THAT THE TUBE DOES
NOT OVERFLOW. Release the hose and pour about half of the mixed cleaner
into the tube. Replace the tube on the cap, while pinching water level control
hose, then pour the remaining cleaner into the control stream box.
5. Switch the "ICE-OFF-WASH" to "WASH" and allow the cleaner to circulate for
approximately 15 minutes, then pull the right side of the water plate down until
the pump stops and hold it until the pump will not re-start when released.
6. The water plate will open and dump the cleaner then close immediately, and the
water system will refill. Repeat this dumping and refilling three (3) times to rinse
out all of the cleaning solution.
7. Mix a sanitizing solution of 60 ml 5-1/4% sodium hypochlorite (household
bleach, or equivalent) and one (1) liter of clean water.
8. As in step #4, pour about half of the sanitizing solution into the water level
control tube and the remaining sanitizer into the control stream box.
9. Allow the sanitizing solution to circulate AT LEAST 15 MINUTES, then dump
and rinse two (2) times as described above. If necessary, reset the water level
probes to the proper levels.
10. While the cleaning and sanitizing solutions are circulating, clean, rinse, and
sanitize all accessible parts of the ice-making compartment of the cuber.
11. After cleaning has been completed, trip the "ICE-OFF-WASH" switch to "ICE"
and check to be sure that the cuber is operating properly, particularly the water
level probes. Then re-assemble and secure all cabinet enclosure panels.

ICE BIN CLEANING INSTRUCTIONS
storage areas.
The bin should be cleaned periodically. If bin drain has any horizontal run, remove ice
around the drain fitting and flush with two liters of hot water monthly. (Long drain lines
should be flushed weekly.)
CAUTION:
RISK OF PERSONAL INJURY, EQUIPMENT DAMAGE OR
CONTAMINATION OF THE ICE BIN.
Do not use ammonia solutions or strong detergents in cleaning any part of the
ice maker or bin.
Never use appliance polishers or other finish preservatives or cleaners in ice
1. Clean exterior of bin frequently.
2. To clean the interior, follow instructions provided with bin.
3. Empty the storage area and disconnect the electrical power supply to the ice
maker(s).
4. Remove the ice maker top and front panels, and drain pan. Remove bin doors,
if possible, following the bin instructions.
5. When cleaning the ice maker, follow the ice maker cleaning instructions and
clean the bin last.
6. Replace all enclosure panels before re-connecting the electrical supply.
WINTER CONDITIONING
Ice cubers which are idle in the winter months require preparation as follows to prevent
damage from freezing:
1. Shut off and detach the water supply to the Ice Cuber.
2. Remove all water from the circulation system, solenoid valve, and condenser.
3. Disconnect the electrical supply.
