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.
