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

SAFETY REGULATIONS
The plug in refrigerated cabinet as described in the 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.
To ensure safe operation in all service conditions, the following
safety precautions must be observed.

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 trouble
free working of the cabinet:
- Do not install the cabinet outdoors
- Do not install the cabinet in the vicinity of heating radiators or
other heating 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 draughts
from air conditioners, ventilators or open doors.
- 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 the cabinet against a wall, make sure the
refrigeration unit fan is free to take in the ambient air from
the room via the front grill area and blow it off at the back.
Adhere to the minimum specific distance of 80mm
- When installing several cabinets alongside or behind one
another, be sure to observe the specific installation plan.
In all installation options, air exit must be unhindered at the back
of the refrigerated cabinet to exclude the accumulation of heat.
Only then is trouble-free operation guaranteed.
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.

REQUIREMENTS FOR ELECTRICAL CONNECTION
The cabinet is connected by inserting the power plug in a socket.
The plug is fitted with a 13amp fuse. The cabinet has an ON/OFF
switch but we recommend the provision of a remote switch. Ask
you electrician.
The socket employed must be properly earthed, firmly installed
and protected by a 32amp circuit breaker type C.
Supply voltage and frequency must be in accordance 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 they are protected from risk of damage
and there is no risk of tripping.
STARTING
If the cabinet has been tilted sharply whilst 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 may exist in the lower part of the
equipment.
Start the cabinet only if installed as described.
- Plug power plug in 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 case 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 non-standard ambient and/or operating
conditions.
The units are delivered with the regulation already factory set.
ADJUSTING THE CONTROLLER
Please refer to the specific instructions included.
AUTOMATIC EVAPORATOR DEFROSTING
Defrosting of the evaporator fins and evaporation of the drip
water formed during the defrosting is performed automatically.
During automatic defrosting, the temperature in the display
compartment may rise slightly.
Defrost frequency as well as duration and time are factory set.
Defrosting is automatic four times a day.
All cabinets have a stainless steel drip tray with an electrical
heating element operated by a float switch, and a hot gas pipe
running under the tray to evaporate the condensate water.
Page 8
CLEANING
A general shut down of the units must be carried out every 30
days in order to carry out general cleaning and allow the
elimination of any ice build up which might exist. For purposes
of hygiene, more frequent cleaning might be necessary.
Make sure that the drain overflows are not obstructed to avoid
significant damage being caused.
Turn off power supply to the cabinet by disconnecting the power
plug before cleaning.
Do not use any aggressive or abrasive cleaning agents. Never
use a water hose or high pressure jet to clean the cabinet.
Cleaning The Outer Casing
Wipe the outer casing with a cotton cloth moistened with
lukewarm water.
The glazed parts of the end walls can be cleaned with a
commercial brand alcohol based glass cleaner.
Cleaning The Internal Surfaces
Remove the merchandise from the display compartment and
transfer it to another storage place.
Do not start cleaning before the internal surfaces have risen to
near room temperature.
- Take accessories out of the display compartment
- Unscrew 2 recessed head screws at the return air grill with a
screwdriver for recessed head screws
- Pull out return air grill backward of the fixing device
No cleaning water must be allowed to flow into the defrost water
drain.
- Moisten cloth with lukewarm water and a little detergent
- Wipe fan wall below the return air grill
- Wipe display compartment with display shelves
- Carefully dry all wiped surfaces with a dry cotton cloth
Page 9
After cleaning, no humidity must remain in the display
compartment.
The defrost water gutter should be cleaned 2–3 times per year.
Replace return air grill in reverse order and then screw on again
Restart cabinet
The cabinet can be reloaded with refrigerated merchandise
approx 40 minutes after putting into operation.

MAINTENANCE
Maintenance must be carried out by authorised technical
personnel.
The positioning and type of the defective elements to be repaired
or replaced can be seen in the spare parts drawings.
In order to avoid accidents: where the manipulation and/or
replacement of electrical components is to be carried out, always
disconnect the units from the electric mains beforehand.
Turn off power supply to the cabinet by disconnecting the power
plug before starting any maintenance on the cabinet.
In case of breakdown in the functioning of the unit, the user
must carry out the necessary steps to prevent the deterioration
of the product. i.e. destocking and removal to operational
storage facility.
Cleaning The Condenser Fins
The refrigerated cabinet normally requires no maintenance
except for cleaning the condenser fins every two to three
months.
- Disconnect the cabinet as described above
- Unscrew 4 recessed head screws with screwdriver for
recessed head screws.
- Remove front grill
- Check whether the condenser fins need cleaning
The condenser only needs cleaning when a layer of dust, fluff
and the like begins to build up between the fins.
- Clean the fins with a vacuum cleaner and brush attachment or
flat nozzle
- Replace the front grill after cleaning
- Put cabinet in operation
Regular cleaning of the condenser is important to save power
and avoid unnecessary servicing.
