5. Air Filter
As the air filter becomes clogged with dirt or dust, the unit’s performance will be reduced.
Do not operate the unit with the air filter removed. This will accelerate clogging of the
condenser and result in failure. Check the filter at least twice each month. If it is dirty,
use warm water and a neutral cleaner to wash the filter. To avoid damaging the air filter,
do not use water hotter than 104°F (40°C). The filter is located behind the front panel.
This filter can be removed by opening the front panel and lifting the filter away from the
condenser. Reinstall the filter after cleaning.
6. Shelves
Remove and clean regularly.
7. Drawers
On units with drawers, the drawers can be removed for cleaning either individually or as
an entire assembly.
• To remove an individual drawer, first remove all food product from the drawer. Pull the
drawer out to its fully extended position and lift up on the handle to disengage the drawer.
Before removing the drawer, carefully support the rear and front of the drawer and then
slowly remove it from the cabinet.
• To remove the drawer frame assembly, first remove the drawers and then remove the
fasteners in the thermal break and in the rear of the cabinet. Carefully slide the frame
out of the cabinet, making sure not to damage the thermal break. Reinstall in the reverse
order, making sure not to overtighten the screws in the thermal break.
• To remove the drawer slide (center slide containing rollers) for cleaning, rotate the top
of the slide away from the frame while the slide is completely inside the cabinet. Drawer
slides do not require lubrication, but slides should be kept clean and free of food.
Note: Drawer slides are dishwasher safe.
B. Maintenance
1. Air Filter
The air filter promotes clean condenser surfaces and efficient unit operation by removing
dirt and grease from circulating air. The filter should be checked monthly and cleaned
when necessary—as described in "A.5. Air Filter".
All other maintenance or service on this unit should be performed in accordance with the
Hoshizaki Service Manual by a qualified service technician.
