Operation

At daily start-up, after switching on, allow 1 hour for the unit to reach operating temperature. The day cover must be closed during this chill-down period.

Pre-chill ALL cold food products prior to loading into unit.

Do not exceed the chill line (the ridge on the inside of the pan) when filling the pans.

When the operating temperature has been reached (0 to 4°C), the day cover can be opened and the pre-chilled product pans can be loaded into the unit.

Place the pre-chilled food product pans into the unit so that there are NO gaps between the pans.

Stir cold product at least once per hour to maintain proper temperatures throughout the pans.

Continually rotate the product.

Do not line the unit with aluminium foil or subwraps etc. This decreases the unit’s efficiency.

During non busy times it is recommended that the day covers are closed.

Never use the unit for extended holding.

At daily shut down, the product must be removed and the unit switched off. This allows the unit down time and prevents excessive ice build up.

General Maintenance Note: The unit must be switched off prior to cleaning

General maintenanceThe unit should be cleaned regularly with a mild soap and water mixture. Do not use abrasive cleaners; they will damage the finish of the unit.

Glass should be cleaned daily or as required using a proprietary glass cleaner. Care should be taken to select a cleaner with minimum odour to avoid food tainting.

Cleaning the condenser

The condenser (pictured) must be kept clean in order to maintain a clear passage through which air may pass. Air is continually drawn through the condenser fins, along with dust, lint, paper, grease, etc. Do not allow this dirt to build up and block vision through the fins. A clean condenser will minimise operating, maintenance and repair expenses. The condenser fins are likely to require cleaning at least once a month but the frequency will depend on unit usage and operating conditions.

Step Action

1 Isolate power and unplug the unit2 Remove the protective grill from the unit3 Gently brush or vacuum the dirt from the condenser fins4 Re-align the fins using a fin comb (H&K Ltd part number S06084)5 Replace the cover panel

If there is a significant dirt build-up that is difficult to remove, contact a refrigeration service company who will be able to blow out the condenser with pressurised air, CO2 or nitrogen.
