NUR Series: Installation & Operation
1. Start up:
Before operating your unit, please ensure that all casters are properly installed. The unit
must be level after it is positioned in its permanent location. This ensures proper door alignment on
all cabinet, adequate condensate water drainage, and proper overall refrigeration system operation.
Electrical power to the unit is generated immediately after plugging the power cord into an adequate
outlet.
2. Set Temperature:
Push the SET key for more than 2 seconds to change the Set point value; The value
of the set point will be displayed and the “°C” or “°F” LED starts blinking; To change the Set value
push the o or n arrows within 10s. To memorize the new set point value push the SET key again or
wait 10s.
3. Temperature controller:
After turning on for the delay time (2 minute), the compressor starts when
cold room temperature ≥set tempe hysteresis, and will be off when cold room temperature
≤set temperature. To protect the compressor, it can re-start unless the time when the compressor
stops every time is longer than the delay time. (2 minutes)
CAUTION:
Setting the temperature control to the coldest setting may result in a warmer cabinet
temperature.
4. Transportation:
Do not incline the unit more than 45° during transportation and do not move the
unit frequently once plugged in.
5. Storage:
Do not overload the unit with products and do not store foods for too long.
6. Maintenance:
Please clean the cabinet with a soft cloth regularly. Unplug the unit before cleaning. If
the cabinet will not be in use for an extended amount of time, disconnect the unit and clean it. Verify
the wiring prior the resuming usage of the unit.
Restart: Please wait 5 minutes to restart the refrigerator after unplugging the unit or a power outage
occurs or it affect the compressor. To save energy, the refrigerator door should not be frequently
opened or left open for a long time.
7. Defrosting:
Timing of defrosting: The electronic control panel is preset to automatically execute 4
defrosting cycles within 4 hours. Its timer will reset to the time or the initial first start-up. In order
to modify the start time for the defrost cycle to the desired time, follow these directions: press the
defrosting button for 6 seconds, the unit will start defrosting at the time, and another cycle will
follow 6 hours later.
Manual defrosting: Press the button on the top right of the display of the electronic thermostat for
6 seconds. The defrosting will start only if the sensor reveals a temperature that is inferior to a pre-
set value. In that phase, the defrosting pilot light and defrost LED switch on. Refrigerator coils are
defrosted by compressor stopping. Freezer coils are defrosted electrically.
CAUTION:
Do not remove ice with a sharp metal instrument.
