Stage of Food Handling| When to Check| Recommended Safe Temps
---|---|---
Delivery| Every time perishable food is delivered| 0° to 7°C is ideal for refrigerated food. –22° C to – 18° C is ideal for frozen food
Storage in refrigerator or cold store| Daily, at least| 0° to 7° C
Storage in refrigerated counter or display| Daily, at least| 0° to 7° C
Deep Freezer| Daily, at least| – 18°C or below
Defrosting frozen meat or poultry| Whenever food is thawed| 0° to 7°C
Cooling| Whenever food is cooked| Minimum core temp.of 70° C for 2 mins
Cooling| Whenever food is cooked| 7° C or cooler, ideally within 90 minutes
Re-heating| Whenever food is re-heated| Minimum core temp.of 70° C for 2 mins
Hot food on display| Frequently while on display| Minimum core temp of 63° C
Cold food on display| Frequently while on display| 0° to 7°C is recommended

The chart above gives the temperatures that are generally accepted as good practice together with the recommended period of time involved where appropriate. Keeping food at these temperatures plays a major part in ensuring that food is safe to eat. Do not leave food standing in a room, or in sunlight (for instance in a shop window)

Cooking at 70° or hotter for sufficient time kills most pathogenic bacteria, although some bacterial spores can survive high temperatures. Food must always be cooked thoroughly, right through to the centre of the thickest part

Remember: Keep cold foods really cold Keep hot foods really hot.

SAFETY REGULATIONS

The plug-in refrigerated cabinet described in this operating manual is designed and manufactured in compliance with the international safety regulations. Like any electrical appliance, it must be handled with all due care, particularly with consideration to ensuring electrical safety.

INSTALLATION

Selecting the Place of Installation
In selecting the place of installation, ensure that the following instructions are observed, this being vital for proper and troublefree working of the cabinet.

• do not install the cabinet outdoors
• do not install the cabinet in the vicinity of heating radiators or other heat sources
• do not install the cabinet where it is exposed to direct sunlight (e.g. through windows)
• avoid the installation of incandescent illumination. Fluorescent lighting is recommended
• do not install the cabinet where it is exposed to drafts from air conditioners, ventilators or open doors
• do not install the cabinet in a shop or room where the ambient temperature is above 25°
• do not stack items on top of the unit
• keep the air intake and outlet area around the front grill area of the cabinet clear of cartons and other obstacles
• when installing a cabinet against a wall, make sure that the refrigeration unit fan is free to take in ambient air from the room via the front grill area and blow it off at the back.

Adhere to the specific minimum distance of 80mm!

• When the cabinet is installed as a stand-alone unit against a wall, a minimum distance of 80mm must be maintained between cabinet back and room wall to ensure free air exit on the cabinet back
• When installing several cabinets alongside or behind one another, be sure to observe the specific installation plan

In all installation options, the air exit must be unhindered at the back of the refrigerated cabinet to exclude the accumulation of heat. Only then is trouble free operatin guaranteed

Requirements for Electrical Connection
All refrigerated cabinets must be PAT tested (Portable Appliance Test) to the legal requirenent.
This is to ensure that all electrical connections and components have not been damaged in transit

The cabinet is connected by inserting the power plug into a socket. The plug is fitted with a 13- amp fuse. The cabinet has an ON/OFF switch but we recommend the provision of a remote switch. Ask your electrician

The socket employed must be properly earthed, firmly installed and protected by a 32-amp circuit breaker, type C

Supply voltage and frequency must be in acccordance with the data shown on the cabinet type plate. The local utility company’s regulations on earth-fault protection must be observed. If in doubt, consult a qualified electrician.

The cabinet must not be plugged into a multiple outlet power strip
Run the power cables so that they are protected from risk of damage and there is no risk of tripping

STARTING and COMMISSIONING

If the cabinet has been sharply tilted while being sited or for counting of accessories, it must be left to stand for at least three hours before being started to allow the lubricating oil to settle in the compressor. Failure to do so can cause total destruction of the refrigeration system

Ensure the means of transporting/positioning used does not damage elements which exist in the lower part of the equipment.

Start the cabinet only if it has been installed as described and where the room temperature is not over 25 ° C

– plug power plug into socket
– switch on

Starting is signalled by the running noise of fans and refrigeration system

SETTING THE STORAGE TEMPERATURE

The temperature regulation parameters as well as recommended defrost times for each cabinet are based on Frost-Tech experience and on the results obtained in laboratory tests.

Regulation which is different from those recommended may be necessary for reasons of nonstandard ambient and/or operating conditions The units are delivered with the regulation already factory-set.

All temperature and defrost regulations must be set by a qualified refrigeration engineer. The buyer responsibility to ensure that the equipment will be fit for the purpose for which the Buyer intend to use the equipment.

ADJUSTING THE CONTROLLER
