Condensate Removal System with Condensate Evap Pan
Cleaning
although each Zero Zone display case is thoroughly cleaned before shipping, the cases should be thoroughly cleaned again before start-up and
routinely thereafter to maintain a clean appearance. With just a few minutes of cleaning each week, the case will remain in top condition.
1. Do not use high-pressure water or steam to clean the interior or any components.
2. Do not wash fan motors. a damp cloth can be used to wipe the fan motors. Cover the fan motors with a plastic bag when washing the case.
3. Wipe out the case interior using a mild detergent and warm water (never an abrasive cleaner).
4. Clean all glass doors, windowed ends, and mirrors using glass cleaner. Cleaning interior glass reduces fogging and increases visibility.
Do not use any cleaning products containing silicon or anti-fog.
5. For Crystal™ freezers, Highlight™ cases, or Reveal™ cases: Internal components can be cleaned after removing coil covers, access
panels, and sheet metal components. Use a mild detergent and warm water or a mild sanitizer.
6.
For Crystal™ coolers only: The drain pan can be flushed after removing bottom wire racks. The coil can be cleaned after removing the
false ceilings, fans, and fan plenums.
7. If the case is equipped with a condensate pan and pump, the drain should be blocked before washing coils. Water can be removed with a
shop vacuum.
8. Coils may be cleaned with a garden hose or pails of water. If the case is equipped with a condensate pan and pump, cases should be
cleaned with a minimal amount of water so the evaporator, pump, and drain pans do not get overfilled.
9. The case drain should frequently be cleaned of debris to prevent clogging. If water is rising, check if the drain is clogged.
Under Case Floor Cleaning (nSF)
The floor under your Zero Zone display case can be cleaned by following these steps:
1. Remove the fasteners attaching the kickplate to the case. The fasteners are accessed from the front of the unit.
2.
With the kickplates removed, remove debris from the floor.
3. Vacuum under the case to remove any dirt, debris, and dust build-up.
4.
Mop under the unit using non-abrasive floor cleaner and warm water.
5.
When finished mopping, squeegee any remaining water under the unit to the floor drains to speed up the drying process. Replace the
kickplates after the floor has dried.
