Introduction

Please take a few moments to carefully read through this manual. Correct maintenance and operation of this machine will provide the best possible performance from your POLAR product.

Pack Contents
The following is included:
POLAR Blast Chiller /Freezer Instruction manual
POLAR prides itself on quality and service, ensuring that at the time of unpacking the contents are supplied fully functional and free of damage.
Should you find any damage as a result of transit, please contact your POLAR dealer immediately.

Installation

Note: Not for use in vans or trailers, food trucks or similar vehicles.
Note: If the unit has not been stored or moved in an upright position, let it stand upright for approximately 12 hours before operation. If in doubt allow to stand.

1.  Remove the appliance from the packaging. Make sure that all protective plastic film and coatings are thoroughly removed from all surfaces.
2. To optimize performance and longevity, ensure a minimum clearance of 2.5cm is maintained between the unit and walls and other objects, with a minimum 20cm clearance on the top.
   NEVER LOCATE NEXT TO A HEAT SOURCE.

Note: Before using the appliance for the first time, clean the interior with soapy water then dry well.

Operation

Storing Food

To get the best results from your POLAR appliance, follow these instructions:

• It is important that food entering the Blast Chiller/Freezer does not exceed a temperature of 90°C.
• It is recommended that metal containers / trays are used as other materials such as plastic or polystyrene containers will act as an insulator and extend blast chilling times.
• Sufficient space must be left between products in order to guarantee a sufficient flow of cold air. Ensure product is not in contact with the internal walls of the unit, and leave sufficient gaps between trays.
• Never obstruct the inlet of the evaporator fans.
• Products that are more difficult to chill because of their composition and size should be placed in the centre of the unit.
• Blast chilling data refers to standard products (low fat content) with a thickness below 50 mm: therefore avoid overlaying products on trays or the insertion of pieces with a much higher thickness, as this will lead to an extension of blast chilling times. Always distribute the product well on the trays and in the case of thick pieces decrease the amount to blast chill.
• Limit the number of times and the duration of time the doors are opened.
•  The chiller should be used for storage for short periods only.
• When removing product that has undergone blast chilling/shock freezing, always wear gloves to protect the hands from cold burns.

Introduction
The appliance has the following operational states:

• If power is interrupted during a timed blast chilling operation, when power is restored, chilling will continue from the time point at which the interruption occurred (with a maximum error of 10 minutes).
• If power is interrupted during a set temperature blast chilling operation, when power is restored, chilling will start again from the beginning.
• If power is interrupted during a storage operation, when power is restored the storage operation will be reset.
• If power is interrupted while in “stand-by” mode, when power is restored the device will be in the same state.

Turn On

1.  Ensure the power switch is set to [O] and turn on at the socket.
2.  Switch on the Power [I]. This will place the unit in standby whilst waiting for the cycle to be selected.

Insert the food probe

• Before selecting which cycle to use, the probe must be inserted into the food. This allows the internal temperature of the food to be measured.
• It is important that the probe is correctly connected to the unit.

Note: To prevent bacterial contamination or contamination of any other biological nature, the needle probe must be disinfected after use.
