Location and building in
The cabinet should be placed in a room which is dry and sufficiently ventilated. To operate efficiently it
should not be positioned in direct sunlight or near warm appliances. Please note that optimal cabinet
performance is obtained at an ambient temperature between +16°C and +32°C.
In environments with both high temperature and high air humidity, the appliance is approved in
climate class 4+.
Refrigerators:
By placing the cabinet in an environment with high air humidity, it might be necessary to acquire extra
equipment for re-evaporation of the drip water in the reevaporation pan over the compressor. This
equipment can be bought as extras.
Stainless steel:
cabinets: Avoid placement of the cabinet in a chlorine/acid-containing environment (swimming-bath etc.)
due to risk of corrosion.
Appliances with drawers must be secured to a stable surface to prevent them from tipping over
when the drawers are fully extended.
The cabinet can be installed freestanding against a wall or it can be built under a worktop.
Important
The cabinet must have sufficient ventilation and free air circulation beneath, above and behind the cabinet.
The cabinet legs under the cabinet and the spacers at the rear of the cabinet ensure
sufficient air space.
The drawings show how much air space is needed.
A. shows a refrigerator free-standing against a wall.
B. shows a refrigerator installed under a worktop (LR/PR170 & LF140). Note the necessary clearance
between refrigerator and worktop. This dimension must be maintained to ensure air circulation. If the
refrigerator is installed under a worktop and this dimension cannot be observed, air circulation must be
provided by making an extract channel in the worktop.
Fig. 1: There must be a minimum
clearanceof 30 mm above
the cabinet.

Solid/glass door:
By placement of cabinets side by side, the minimum distance shown below should be regarded, due to risk
of condensation between the cabinets.
If additional sensors or similar are to be fitted to the inside of the cabinet, care must be taken to avoid
damaging the wiring as this may prevent the appliance from functioning. If necessary, please contact your
local distributor or Arctiko for information on wiring location.
Cable entries through the cabinet wall should be equipped with a lead-through tube and kit. Such kits are
available through local distributors.
Whether the standard alarm functions with which the appliance is equipped are sufficient or whether
additional surveillance systems or the like are required should be assessed in each specific case. If
substances which are either irreplaceable or replaceable only on the expenditure of considerable time, effort
or money are to be stored in the appliance, it is advisable to take suitable precautions regarding storage and
surveillance.
The appliance has been manufactured in accordance with EN 60079-15: Electrical apparatus for explosive
gas atmospheres - Part 15: Type of protection "n".
Connection in zone 2 environment:
The appliance must be connected to the external power supply using a suitable device which mechanically
prevents the plug and socket from being separated unintentionally. The connection must be labelled:
”DO NOT SEPARATE WHEN ENERGIZED”
Connection in areas not covered by zone 2 regulations:
The appliance may be connected in accordance with applicable heavy current regulations.

Important! Applies to cabinets with glass door and/or drawers:
Anti-topple brackets must be installed to avoid the cabinet toppling over when opening the door.
The brackets which are delivered with the cabinet must be fastened to the wall behind the cabinet, as
shown in the drawings.
Fuses and similar must never be removed or replaced while the appliance is connected to a power source.
The electrical terminal box must never be opened while the appliance is connected to a power
source.
The compressor starting equipment must never be dismantled while the appliance is connected to a power
source.
The halogen lighting must never be dismantled while the appliance is connected to a power source.
Whenever electrical components are dismantled or replaced, the appliance must be moved to an area in
which there is no risk of ignition caused by the electrical components or gases contained in the appliance.

Connection to electricity
The cabinet is intended for connection to alternating current. The connection voltage (V) and frequency (Hz)
are shown on the name plate in the cabinet . Power connection is made by a three pin plug to a wall socket.
Any requirement for earthing from the local power supply must be met. The cabinet plug and wall socket
should then give a correct earthing. If you are in doubt, approach your supplier or authorized electrician.
Warning - this appliance must be earthed
The flexible cord fitted to this appliance has three cores for use with a 3-pin 13 Amp 3-pin or 15-Amp plug.
If a B.B. 1363 (13 Amp) fused plug is used, it should be fitted with a 13 Amp fuse.
Important
The wires in this mains lead are coloured in accordance with the following code:
Green-and-yellow: earth
Blue: neutral
Brown: live
The colours of the wires in the mains lead of this appliance might not correspond with the coloured markings
identifying the terminals in your plug. Proceed as follows: The wire which is coloured green-and-yellow must
be connected to the terminal in the plug which is marked "E" or marked by the earth symbol or coloured
green-and-yellow. The wire which is coloured blue must be connected to the terminal which is marked with
the letter "N" or coloured black. The wire which is coloured brown must be connected to the terminal which
is marked with the letter "L" or coloured red.
In case of technical problems or failure, always contact authorised service personnel for repair.
Never open the electrical terminal box or other electrical components yourself.
Note that EN 60079-15 contains special regulations regarding appliances in zone 2.
Voltage free contact
The voltage free contact is providing with a remote alarm in case of temperature alarm, power failure or
door alarm, with separate delay.
•or normally open connect one wire in NO and one in COM.
•or normally closed connect one wire in NC and one in COM.

Starting up (PC-Board MPC 46)
Plug in the cabinet
To start, press the START/STOP key.
When starting up the display will first show the software version of the cabinet followed by the program
variant. When the display switches to displaying temperature the cabinet is ready for use.
To turn off the cabinet, push for more than 6 seconds.
Servicing:
Make sure the appliance is switched off at the socket before service is performed on electrical parts. It is not
sufficient to switch off the cabinet by the START/STOP key as there will still be voltage to some electrical
parts of the cabinet.
