SERVICE PRECAUTIONS FOR R600A SYSTEM
Features of R600a refrigerant
• Achromatic and odorless gas.
• Flammable gas and the ignition (explosion) at 494°C / 921°F.
• Upper/lower explosion limit: 1.8%~8.4%/Vol.
Features of an R600a refrigeration unit
• Requires about 60% of the refrigerant required by an R134a system
• The suction pressure is below 1bar (abs) (14.5 PSI) during the operation.
• Any type of dryer is applicable
• The compressor has a label referring to the R600a refrigerant.
CONTROLS AND ELECTICAL SYSTEM
CONTROL FUNCTIONS
Silent Mode vs Dynamic Mode:
In the Dynamic Climate mode, the interior fan cycles on 20 seconds and off 30 seconds to
circulate the inside air evenly even when the set temperature is reached. Dynamic Climate
mode is NOT the factory preset mode. To change to Dynamic Climate mode, touch and hold the
DOWN key for approximately five seconds. The beverage fridge will beep five times to confirm
Dynamic Climate mode is on. To change back to default (Silent) mode (Also referred to as
energy saving mode), touch and hold the UP key for approximately five seconds. The beverage
fridge will beep three times to confirm default (Silent) mode is on.
Eco Demo Mode:
By pressing and holding the “UP” & “DOWN” and “LIGHT” keys all at the same time for at least
5 seconds, the indicator light will flash five times to confirm the unit has been put into Eco Demo
mode. The indicators for Fahrenheit and Celsius degree will be ON. In Eco Demo mode, the
compressor and all fan motors are OFF. NOTE: To perform the multi-key function, press and
hold the first key, then press the rest key the required number of times and then release all the
keys.
SABBATH Mode:
Sabbath mode is available for the observance of certain religious holidays. This mode turns off
the displays, interior light and audible alarms and prevents them from turning on again. Normal
cooling operations will still take place. To initiate Sabbath mode, press the POWER and LIGHT
keys at the same time for at least 5 seconds. The indicator light will flash four times and confirm
the Sabbath mode is ON. Sabbath mode can be exited by repeating the above process. The
Sabbath Mode will automatically exit after 96 hours.
Page 11
ALARM SYSTEM
Temperature Display
During normal operation, the temperature display on the control panel will show the temperature
inside the appliance.
The temperature display will flash if:
• A different temperature is being set
• The temperature in deviates by more than 5°C from the set temperature. Note: To view the
“set” temperature at any time, touch the “UP” or “DOWN” mark, the “set” temperature will
temporarily flash in the LED display for 5 seconds.
If the LED readouts display the icon “--" and flash, that means the display temperature is out of
the range from -9 to 37ºC for Celsius degree and from 16 to 99ºF for Fahrenheit degree. That is
normal.
Temperature Alarm
An alarm will sound if the temperature rises or falls outside the temperature range. The
temperature display will flash at the same time. The temperature the appliance is set at
determines the temperature the appliance recognizes as being too warm or too cool.
The alarm will sound and the temperature display will flash if:
• When there has been a lengthy interruption to the power supply.
• When too many items have been put into the unit at one time.
• When the door is not been closed tightly.
Door Alarm
If the door has been left open for more than 60 seconds, the alarm will sound. After closing the
door, once the set temperature has been reached in the appliance, the alarm stops and the
temperature display stops flashing. However, if the noise disturbs you, you can switch the alarm
off before this if you wish by pressing the POWER key once. The alarm will stop. The
temperature display will continue to flash until the set temperature has been reached. The
display will then light up constantly, and the alarm system is fully active again.
Page 12
OTHER FUNCTIONS
Temperature Memory Function
In the event of a power interruption (power surge, breaker switch, etc.), the unit will remember
the previous temperature settings. When the power is recovered, the unit will operate with the
last temperature set-point.
Interior Light
Touching the LIGHT button toggles between 2 modes of operation for the internal lights:
Functional (default) mode and showcase mode. If you are in functional (default) mode, the lights
will turn on only when the door is open. If you are in showcase mode, the lights will be on all the
time.
Defrosting
• Defrosting is performed each time the total running time for the compressor reaches
• 10 hours.
• During the defrosting cycle, the compressor is OFF and the fans operate continuously.
• After 30 minutes, the defrosting cycle is completed
• During the defrosting cycle, the storage temperature may vary by 5 or 6 degrees.
• Frost may be accumulate on the evaporator if the unit is repeatedly opened in a high heat or
high humidity locations. If this frost pattern does not clear within 24 hours, your unit will
require manual defrosting.
ºF/ºC Selector
Select the temperature display setting in Fahrenheit or Celsius degree. To change the
temperature from Fahrenheit to Celsius or from Celsius to Fahrenheit, press and hold the
LIGHT key for 5 seconds.
TEST MODE
Press and hold the “LIGHT” and “UP” keys at the same time for 5 seconds with the power
ON. The indicator light will flash twice to confirm the input and the unit will run in the TEST
MODE. The compressor and all fan motors will operate continuously & independent from the
SET temperature. At the same time, the display shows the icon “--". The TEST Mode will
automatically exit after 30 minutes or you can stop the TEST mode by disconnecting the unit
from power source.
