Cleaning, Sanitation and Maintenance - D Series

This ice system requires three types of maintenance:

•

Remove the build up of mineral scale from the ice

machine’s water system and sensors.

•

Sanitize the ice machine’s water system and the

ice storage bin or dispenser.

•

Clean the remote air cooled condenser.

It is the User’s responsibility to keep the ice machine and ice storage bin in a sanitary condition. Without

human intervention, sanitation will not be maintained. Ice machines also require occasional cleaning of their

water systems with a specifically designed chemical. This chemical dissolves mineral build up that forms during

the ice making process.

Sanitize the ice storage bin as frequently as local health codes require, and every time the ice machine is

cleaned and sanitized.

The ice machine’s water system should be cleaned

and sanitized a minimum of twice per year.

1. Remove the front panel.

2. Remove the evaporator cover.

3. Remove all ice from the storage bin or dispenser.

4. Push and release the Clean button. The yellow

Clean light will blink and the display will show

C. The machine will harvest any ice, drain the

reservoir and begin to refill it.Remove all ice from

the storage bin or dispenser.

5. Observe code display, when it blinks the

characters “A d 1” immediately go to the next

step.Observe code display, when it blinks the

characters “A d 1” immediately go to the next step.

6. Pour 24 ounces of Scotsman Clear 1 ice machine

scale remover into the reservoir. The unit will

circulate the scale remover, then drain and flush

it. This will take 35 minutes, then the machine will

stop and the display will show O.

7. Mix a cleaning solution of 1 oz of ice machine

cleaner to 12 ounces of water.

Note: If unit has not been de-scaled for an extended

period of time and significant mineral scale remains,

repeat steps 6 - 8.

8. Remove curtain from unit.

9. Locate ice thickness sensor. Squeeze mounting

legs together to release sensor.

10. Remove water distributor from ice machine by

disconnecting its hose, squeezing the retaining

snaps together and pushing the distributor to the

right as far as possible. Lift up to remove. Inspect

distributor for restricted orifice holes. Be sure all

holes are full open..

11. Locate water level sensor. Squeeze

catches together and pull up to remove

sensor. Separate probes from housing and

wash all surfaces with ice machine scale

remover solution. Return probes to holder.

12. Wash the metal surfaces of the ice thickness

sensor and the adjustment screw with ice machine

cleaner solution. Also wash the water distributor,

water level sensor probes and curtain with the ice

Step 13

Release

probes by

pushing in on

white buttons

and pulling

probe down

out of holder.

Ice machine scale remover

contains acids. Acids can

cause burns.

If concentrated cleaner comes

in contact with skin, flush with

water. If swallowed, do NOT

induce vomiting. Give large

amounts of water or milk. Call

Physician immediately. Keep

out of the reach of children.
