Installation

Upon receipt of equipment inspect for damage. Any damaged parts should be reported to H&K Ltd within 24 hours of receiving the unit.

The unit must be kept upright at all times (i.e. in working position). It is designed to be used on a level surface with a minimum of 25mm clearance at the rear of the unit. Sufficient air circulation around the unit is necessary in order for the freezer to operate properly.

Temperature settings on the Controller have been factory pre-set and should not require adjustment.

Before initial start-up leave the freezer to stand for 2 hours without power. This is to prevent any damage to the internal refrigeration components.

The Product Rack should be positioned inside the unit. This ensures that cold air is allowed to circulate round the frozen product within the unit. (This part can be purchased separately: see parts list on page 10)

Operation

At daily start-up, after switching on, allow 1 to 2 hours for the unit to reach operating temperature. The lid must be closed during this chill-down period. When operating temperature has been reached (-18 to -24°C), food product (which must be at least -18°C prior to loading) may be loaded into the freezer.

At daily shut-down, switch off the unit and remove lid assembly to allow the unit to de-frost. Wipe off excess water with damp cloth.

The exterior of the unit should be cleaned daily with a damp cloth rinsed in a mild soap and water mixture. Do not use abrasive cleaners as they will damage the finish of the stainless steel. The interior of the unit and Product Rack should also be cleaned daily, with a mild soap and water mixture.

Maintenance

Ensure power is disconnected before attempting any maintenance work

Cleaning the condenser

The condenser (pictured below) 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 front of 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 blow out the condenser with pressurised air, CO2 or nitrogen.
