Weekly
Air Filters (air-cooled)
1. Inspect for dust and wash dirt with warm water and neutral detergent.
Monthly
External water filter
1. Make sure that the pressure is adequate and make changes if needed.
Outside of the icemaker
1. Wipe it with a clean, soft cloth, and use a cloth dampened with a neutral
detergent to wipe away any accumulated dust or grease.
2. Clean the chlorine dye (green spots) with non-abrasive detergent.
The bottom of the ice
maker
1. Wipe clean with clean cloth and warm water.
Every six
months
Dispenser and reservoir
1. Clean and disinfect according to the disinfection instructions given in the
instruction manual.
Evaporator condensate
drain pan and Geared
motor drain pan
1. Wipe clean with clean cloths and warm water, and slowly pour a cup of
disinfectant solution (prepared as described in the instructions for disinfection
in the manual) into the evaporator condensate drain pan.
2. Take care not to overflow the drain pan.
3. This disinfectant solution will flow out through the geared motor drain pan and
drain passage.
4. Rinse repeatedly with a glass of clean water.
Ice maker and reservoir
1. Always check that it is kept clean.
Ice exit fixing
seal bolt
1. Check for leaks around the seal bolt. Tighten if necessary and replace O-rings.
2. Always replace the O-ring when loosening the seal bolt and tighten it again. If
there is no O-ring, apply Loctite 243 or equivalent fixing agent so that it does not
leak.
Every year
Water supply valve and
Drain valve
1. Close the shutoff valve to shut off the water supply line and drain the water.
2. Clean the inlet of the water supply valve and check the water supply valve and

and lower bearings (ice exit head and lower housing) (Paid service)
Mechanical seal
1. Check for leaks in the bottom housing, and if there is a leak, disassemble the
auger to replace the mechanical seal. (Paid service) (Water with a lot of calcium
will shorten the life of replacement parts.)
Every three
years
Upper and lower
bearings,
Housing O-ring,
Mechanical seals,
Evaporator cylinder,
Auger
1. Please check if the auger and bearing clearance exceeds the factory
recommended value (0.5mm or less (0.02mm or less for AIWD160 model)), and
