3.Product Operation Rules

First power-on
After first power-on, the refrigerator shall operate with the cold chamber set at 5℃and the freezing chamber set at -
18℃.
The function of adjusting the temperature manually
Temperature regulation of cold chamber (2℃~8℃)
Under t he unlocking state, keep long press of " SET" key for 3 seconds, and press "SET" key to adjust the temperature
of refrigerating chamber after the temperature zone icon switches to the refrigerating chamber. Then, press once
"SET" key, the temperature will descend 1℃, and the gears of the refrigerating chamber cycle in "08" - " 07" - " 06" - "
05" - " 04" - " 03" - " 02" - " 0F" - " 08" . Stop the key operation after selecting the appropriate temperature and wait
for 5 seconds, then the set temperature gear is confirmed.
Temperature regulation of freezing chamber (-22℃~ -15℃)
Under the unlocking state, keep long press of "SET" key for 3 seconds, and press "SET" key to adjust the temperature
of freezing chamber after the temperature zone icon switches to the freezing chamber. Then, press once "SET" key, the
temperature will descend 1°C, and the gears of the freezing chamber cycle in "- 15" - “ - 16" - " - 17" - " - 18" - " -
19" - " - 20" - " - 21" - " - 22" - " - 15" . Stop the key oper ation after selecting the appropriate temperature and wait
for 5 seconds, then the set temperature gear is confirmed.
Fast cooling function
When the display panel is unlocked, press the "Function"button repeatedly until the "Super Cool"icon
flashes, and then stop operating any button and wait for 5s to activate the fast cooling function of cold chamber. Such
operation can quit the fast cooling function by hand.The fast cooling function operates for 2h, and then stops
automatically .
When the "Super Cool"function is on, set temperature to 2℃for refrigerator compartment, until the function

exit quick refrigerating function. Open refrigerator door over three minutes exit quick refrigerating function
exits. (Under quick refrigerating status, adjust set temperature of refrigerator compartment to automatically
under quick refrigerating status.)
Fast freezing function
When the display panel is unlocked, press the"Function"button repeatedly until the "Super Freeze"icon
flashes, and then stop operating any button and wait for 5s to activate the fast freezing function of
freezing chamber . Such operation can quit the fast freezing function by hand. After the fast freezing
function is activated, the refrigerator will start the strong freezing for 4h, and then stop the fast
freezing automatically .
When the "Super Freeze"function is on, set temperature to -24℃for freezer compartment, until the function exits.
(Under quick freezing status, adjust set temperature of freezer compartment to automatically exit quick freezing
function. Open freezer door over three minutes exit quick freezing function under quick freezing status.)
Smart function
Under unlock status, repeatedly press "Function"key until the "Intelligence Temp.Control"icon flashes. Stop key
operation and wait for 5 seconds to enter intelligent function. Manually exit intelligent function through the same
operation.When the "Intelligence Temp.Control"function is on, the refrigerator will automatically monitor the
status of all compartments and run efficiently. Under intelligent status, the refrigerator can automatically enter
quick-refrigerating or quick freezing function according to the temperature in refrigerator and freezer
compartments. (Setting other functions under intelligent status can automatically exit intelligent function.)
Child lock function
Under unlock status, enter " "function:
Automatically on: the child lock function is automatically on after no key operation for 30 seconds," "
icon is lit, and the key board is locked;
Exit child lock: when the " "icon is lit, long press "Function"key for 3 second to unlock.

Refrigeration shut down function
Under the unlocking state, repeatedly press the "SET" key for 3 seconds, and press "SET" key to adjust the
temperature of refrigerating chamber after the temperature zone icon switches to the refrigerating chamber. Stop
the key operation after selecting the“0F" gear of refrigerating chamber and wait for 5 seconds, then enter the
refrigeration shut down function. If the setting temperature of the refrigerating chamber isn' t " 0F" , the
refrigeration shut down function is exited. ( Under the refrigeration shut down function state,
the refrigeration shut down function may be exited automatically when conducting the setting of other functions.
Note: before starting the refrigeration shut down function,please take out the foods in the refrigerating chamber. )
Under the on-state of " refrigeration shut down" function, the refrigerating chamber will enter the off-state.

Technical Data

4.Refrigeration System and Electrical
Control
The cold circulation system is as shown in the figure. TRF-460WEXDA+ is single-system, completely air-cooled
frost-free refrigerators. The refrigerating system is composed of compressor, evaporation coil, condenser, dew-proof
pipe, drier-filter, capillary tube, fin evaporator, return pipe and return transition pipe in the refrigerant flow direction.

bottom up on the left and the second row from bottom up on the right
respectively. When fixing the foam, the aluminum foil cannot be attached to
the fins but only to the baffle plate.
Wrap the foam fixing block with
aluminum foil.
