• This unit is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the unit by a person responsible for their safety.

BEFORE USING FOR THE FIRST TIME

IMPORTANT: Before switching the unit on, we recommend you allow it to stand upright for 8 hours. Failure to do this may result in damage to the unit.

• Remove the wooden pallet and the packing.
• To ensure correct operation, it is important that the unit is level. Use a spirit level to check.
• Before operation, the protective film must be removed, and we recommend that the cabinet is cleaned for reasons of hygiene and to remove any residue left from manufacture.
• For good circulation, vents must not be blocked. Keep a minimum of 100mm of clear space around the preparation counter. Your Husky unit should be placed on flat and firm surface for quieter operation.
• Do not expose the unit to direct sunlight or a heat source such as ovens, radiators, heaters, etc.
• Do not under any circumstances place heated food or beverages in your Husky commercial preparation counter.
• Do not open the door more often than necessary to lessen the escape of cold air.
  • For better air circulation, do not overfill the unit.
• Adjust the thermostat according to the amount of product and the ambient temperature.

Troubleshooting

Before calling Technical Support, please check the following points; you may be able to solve any problem yourself.

Problem	Solution
The sound of flowing liquid may be heard.	This is the refrigerant circulating and is part of normal operation.
There is frost on the unit.	A little frost develops if the ambient humidity is high.Wipe away with a soft cloth.
The compressor cannot be heard but the preparation counter inner temperature reads normally.	This is part of normal operation. High levels of insulation means that the compressor may not need to operate for long periods.
Compressor does not work.	1. Check the power cable is con nected and the socket is switched on.2. Check the fuse and replace with a fuse of a similar rating if necessary.3. Check the power switch is in the ON position and the thermostat is on the correct setting.
The unit is excessively noisy.	Check the floor is level and the unit is securely positioned.
The compressor may be heard working constantly.	If the temperature inside is too high, this constant running of the compressor may be explained by:1. Warm items being placed into the unit. Ensure warm items are never placed into the unit.2. The doors are not being closed properly. Always ensure the doors are closed securely.3. A build-up of ice on the evaporator. Defrost the preparation counter regularly.
	If the temperature inside is correct, then this constant running may be due to:1. The ambient temperature is too high. If possible try to move the unit to a cooler location, or out of direct sunlight.2. The thermostat is set too low. Check and adjust as necessary.3. The thermostat is not working correctly. Refer to an engineer.

Connect the preparation counter to a power outlet and press the Power switch.

The thermostat has been pre-set, and in most cases it is not necessary to adjust the settings. When the unit is operating normally, the display will show the current temperature.

To display the set temperature press the button. Press the button again to return to normal operation.

To set a new temperature, press SET the display will flash and the current set temperature will be displayed. Press the button to increase the set temperature, or press the button to decrease the set temperature. Press the button to save the new setting. The display will flash with the new value and then revert to display the cabinet temperature.

Please note:

1. When the chiller is connected to the mains for the first time there will be a short delay before cooling starts. During this time the Refrigeration Light will flash. After the short delay, cooling will begin and the Refrigeration Light will be illuminated. When the chiller reaches the set temperature, the Refrigeration Light will be off.

2. If you do not press any button, after six seconds the controller will return to its normal display.

ALARM CODES

PFI flashing in the display indicates that the cabinet sensor is defective. The unit will attempt to maintain the set temperature until the fault is repaired.

PF2 flashing in the display indicates that the evaporator sensor is defective. This does not compromise the operation of the unit, but the fault should be repaired as soon as possible.

DEFROSTING

The unit defrosts automatically at preset intervals. If however the doors are opened too often, or if the unit if in a location with high humidity, or if the contents are changed more frequently, it may be necessary to defrost the unit manually. To start or stop manual defrosting, press the button for six seconds. The Defrosting Light will be illuminated. Melt water runs to a container placed in the compressor compartment and evaporates. After defrosting is complete, the unit will return to normal operation.

ensure appropriate temperature control and maintain energy efficiency. Use a vacuum cleaner fitted with a soft brush attachment to remove dust carefully from the condenser, the components and grilles (see 'Cleaning the filter' on page 7).

The external and internal surfaces of the unit should be cleaned regularly. Switch the unit off and disconnect the plug from the mains socket. Clean the external and internal surfaces of the unit with a mild soap solution, then wipe dry. Do NOT use cleansers containing chlorine or other harsh cleansing agents, as these can damage the stainless steel surfaces and components. Use mild soapy water to clean the gasket and seals.

GETTING SERVICE ASSISTANCE

The cooling system is a hermetically sealed circuit and does not require any maintenance other than regular cleaning (see 'Cleaning').

If the unit fails to work, first check the power supply. If you cannot locate the reason for the failure, please contact your supplier, stating the model and serial number of the cabinet. You may find this information on the rating plate, which is affixed on the back wall.
