current is given on the rating plate.
- Ground protection - To prevent the user of getting exposed to electrical
shock, in the event of a insulation damage, the appliance must be grounded.
- The installation must always be secured with a minimum 10 A fuse.
- If more than one appliance needs to be installed, each appliance
must be connected to an individual fuse group.
When installing the appliance, make sure the protected earth is grounded. If
the connection is a 3-prong connection, use a three-pin plug and connect the
conductor with yellow / green insulation to ground. In order to maintain a
stable operation of the appliance, voltage variation cannot dier more than
±10 percent of the nominal voltage supply.
Always follow local regulations when preparing an installation. If in doubt
always contact your local authorities.

Cooling system
The ULUF range is fitted with a direct cooling system. The evaporator is an in-
tegrated part of the shelves in the appliance and divides the thermal radiation
into levels inside the cabinet ensuring a uniformity of only ± 2°C.
Single compressor technology
The Arctiko ULUF range also comes with a single compressor technology.
in comparison to the normal casade system, these appliances only needs 1
compressor to reach the desired temperature.
Dual cooling system (optional)
As an option you can purchase our ULUF models with dual cooling system.
The dual cooling system is designed with two independent cooling cycles
which oers optimal security of your stored products in the unlikely event of a
failure in one of the cooling cycles. In case of failure, the other cooling cycle
will serve as a backup, guaranteeing that your stored products will be kept at
the set temperature.
An Arctiko appliance which oers dual cooling system can be identified by the
denomination of –D in the end of the model
designation (e.g. ULUF 700-D).
Filterless construction
Arctiko’s single compressor system is designed as a filter-less system, which
prevents problems caused by dust building up in the filter. This minimizes the
maintenance of the cooling system and secures a more stable operation.

Main menu

22
Attention!
The factory setting for door alarm activation is 5 minutes. To change this setting, contact
the distributor/seller of the appliance. The user can only enable/disable this function.
- High temp. alarm - If the temperature in the appliance rises above the “High
temp” setpoint longer than the “Alarm delay” setting defines, the high
temperature alarm will be activated.
If products with a temperature above the “High temp” setting is placed in the
appliance near the temperature probe, it may trigger the high temperature
alarm.
Example:
The setpoint is -80°C, the “High Temp.” is set to -70°C and the ”Alarm delay”
is 15 minutes. When the temperature in the appliance rises above -70°C for 15
minutes or longer, the alarm will be activated.
Please note: The temperature probe is measuring the temperature of the air
in the appliance, not the temperature of the products placed in the appliance.
The temperature of the air will change more rapidly than the temperature of
the products.
23
Attention!
When changing the high temperature setting, remember to have the setpoint of the
appliance in mind. If the “high temp.” is set lower than the appliance setpoint, this will
activate the alarm. You can change the time settings for the “high temp” in the custom
menu when accessing “temp. Alarm delay”.
- Low temp. alarm - If the temperature in the appliance falls below the “Low
temp. alarm” limit for a period longer than the “Alarm delay”, the low
temperature alarm is activated.
If products with a lower temperature than the low temperature alarm setting is
placed against or close to the temperature probe inside the appliance, it may
result in the low temperature alarm being triggered.
Example:
The setpoint is -80°C, the “Low Temp.” is set to -95°C and the ”Alarm delay”
is 15 minutes When the temperature in the appliance falls below -95°C for 15
minutes or longer, the alarm will be activated.
Please note: The temperature probe is measuring the temperature of the
air in the appliance, not the temperature of the products placed in the
appliance. The temperature of the air will change more rapidly than the
temperature of the products.
Attention!
When changing the low temperature setting, remember to have the setpoint of the
appliance in mind. If the “low temp.” is set higher than the appliance setpoint, this will
activate the alarm. You can change the time settings for the “low temp” in the custom
menu when accessing “temp. Alarm delay”.
- Case 1: A door opening can cause the temperature to rise inside the cham-
ber. In this case, the temperature rises above the High Temperature alarm
level, but falls again within 15 minutes. In this case, no alarm is
activated.
- Case 2: Loading products in the chamber can cause the temperature to
rise inside the chamber. In this case, the temperature rises above the High
Temperature Alarm Level, and the recovery time last longer than 15 minutes.
– Therefore, the High temperature alarm will be activated.

Please note that during power failure, the cooling system will not be
operational! - When the power returns, the appliance will return to normal
function. We highly recommend NOT to open the door during power failure,
except for moving the products to another appliance or location. An open
door will increase the temperature inside the chamber.
The appliance is equipped with a backup battery, which is able to maintain the
controllers logging feature and visual, audible and remote alarm features for
a minimum of 72 hours. By pressing the on/o button while in power failure
mode, the display will light up and show the duration of the power failure and
the current temperature for a brief moment, and then turns o again.
The compressor failure alarm cannot be set in the settings menu. It is factory
preset and will only appear in the display in case of compressor failure. The
compressor failure alarm is only applicable for appliances with dual cooling
system. The compressor failure alarm activates if a compressor operates
outside normal conditions. The activation of the compressor failure alarm will
switch o the compressor that operates abnormally and keep the other com-
pressor running. The malfunctioning compressor is deactivated to protect the
compressor from running outside normal conditions.
Important: Please note that the compressor will not be reactivated by
accepting the alarm.
Recommended actions
If it is a non-recurring alarm, the compressor can be reactivated by restarting
the appliance (switching the appliance o and on again using the ON/OFF
button). If it is a recurring alarm, please contact your local distributor for
technical support.
Description of compressor failure alarm
- Probe failure - The probe mounted in the appliance measures the
temperature of the chamber and controls the operation of the cooling system.
f the probe is disconnected or damaged, the probe failure alarm will be
activated and the cooling system will stay in operation controlled by a timer
function. If the probe errors, the temperature will show + 55°.
- Power failure - The appliance needs power to operate the cooling system.
In case of power loss, the controller will go into power failure mode and the
screen will go black. The alarm (red light) will start to flash.
Attention!
The Power failure icon will remain in the display until the alarm is accepted.
Logging interval
The controller has a built-in memory for logging the
operating data of the appliance. The controller automatically logs the data at
the set time interval. The time interval is adjustable in minutes.
Attention!
The factory log setting is one minute. To provide the best service and support Arctiko
STRONGLY recommends keeping this setting. When logging every minute, the capacity
of the memory is more than 20 years. Changes to the logging time interval will not be
activated before the device is reset. Turn the appliance OFF and then ON.

Calibration
Temperature probes are mounted inside the appliance. Probe 1 controls the
cooling system and monitors the temperature inside the appliance.
To ensure precise and consistent operation, the probes can be calibrated to
oset potential changes and drifts in measurements. We recommend you to
calibrate the probe temperatures once a year.
Automatic defrost
Automatic defrost is NOT possible on the ULUF range. – Please see
Maintenance /defrosting.
Manual defrost
The manual defrost function of the G214 controller is NOT possible to be
enabled on the ULUF range. – Please see Maintenance /defrosting.
Probe at main screen
The temperature probe of the appliance (Probe 1) controls the cooling system.
It is possible to add up to two optional extra probes (Probe 2 and Probe 3) for
temperature monitoring.
The chamber probe is measuring the air temperature inside the appliance to
control the operation of the cooling system, when the compressor turns on
and o the temperature will rise and fall accordingly.
To get a better monitoring of the actual temperature of the products stored
in the appliance, probe 2 and/or probe 3 can be installed and placed in a
glycerol-filled bottle inside the appliance.
The probe related to the temperature monitoring shown on the main screen
is changed in this menu. The probe, which is selected, is shown above the
temperature in the main screen.
The temperature alarms will react to the probe selected in this menu. All three
probes can be calibrated in the “Calibration” menu. The probe displayed on
the main screen can be changed in this menu.
Attention!
Only Probe 1 is used for temperature control. Do not move or exchange for one of the
other probes as this may aect the appliance’s performance.

Hysteresis
The hysteresis in combination with the setpoint defines the temperatures for
starting and stopping the cooling compressor in the appliance. E.g. with a
setpoint of -80°C and a hysteresis of 2, the compressor will start when the
temperature in the appliance reaches -79°C and stop again at -81°C.
Attention!
Do not change the hysteresis setting without contacting a service
representative. If set incorrectly, it may severely aect the stability and
cooling performance of the appliance.
Temp. range limits
The temperature range limits define the highest and lowest temperature the
setpoint of the appliance can be set to.
Attention!
Changing these parameters and operating the appliance outside of the
specifications listed in the technical data may aect the performance of the appliance
negatively or cause damage to the appliance. The technical data can be found on Arc-
tiko’s website or by contacting the seller of the appliance.
