ELECTRONIC CONTROLS

(A) ON/OFF BUTTON: Your R-AS-10 unit's ON/OFF button has two uses: The first is to turn your R-AS-10 unit on and off.
The second allows for you to select temperature display in either Fahrenheit or Celsius. Temperature display can be
changed to indicate either degrees (F) Fahrenheit or degrees (C) Celsius. To change between temperature scales: While
unit is plugged in and turned off, Press and hold the ON/OFF button for five seconds, after 5 seconds the display will show
"de9F" or "de9C", release the ON/OFF button, display will continue to show "de9F" or "de9C" for three seconds then display
will go blank: Press ON/OFF button to turn your R-AS-10 unit on. Display will show temperature followed by "F" or "C" to
allow at glance recognition of temperature scale. Repeat this step to change temperature scale again.
"de9F" indicates your R-AS-10 unit will display temperature in Fahrenheit.
"de9C" indicates your R-AS-10 unit will display temperature in Celsius.
(B) POWER INDICATOR "ON" LIGHT: Your R-AS-10 unit is equipped with an on indicator light. When illuminated the on
light indicates Power is ON.
(C) CYCLING INDICATOR LIGHT: Your R-AS-10 unit is equipped with a cooling system cycle indicator light. When cycle
light is "ON", this indicates your R-AS-10 unit is cooling down to the desired temperature. When the R-AS-10 refrigeration
compressor is running the cycle light will come "ON" until your R-AS-10 has reached the desired temperature, and go
"OFF" when your R-AS-10 has reached desired temperature.
(D) TEMPERATURE DISPLAY: Your R-AS-10 unit allows you to select the temperature display in two modes, Actual
temperature or Set Point temperature. Set Point temperature is the FWE factory default. In circumstances where displaying
the Actual temperature is desired the FWE R-AS-10 AIR SCREEN allows you to choose this function. Actual temperature
will display internal cabinet temperature acting as an internal thermometer. To switch between Set-Point and Actual
temperature display press and hold the temperature recall button. Display will flash "S" or "A" then display "SET" for
Set-Point or "ACT" for Actual. When display is "SET" or "ACT" release the temperature recall button, to accept the new
setting press and release the temperature recall button.
(E) TEMPERATURE SETTING: Your R-AS-10 units operating temperature is PRE-SET at 34°F (1.1°C) with an operating
temperature range of 33°F to 38°F ( 0.56°C to 3.33°C). To change temperature press the up or down arrow temperature
setting buttons.
(F) TEMP RECALL: Your R-AS-10 unit is equipped with an easy access temp recall button. The temp recall button
has two uses.
First is to momentarily display set-point or actual temperature. When your R-AS-10 unit is set to display Set-Point
temperature press and release the temp recall button to see actual temperature, display will show actual temperature for
3 seconds then revert back to Set-Point display. When your R-AS-10 unit is set to display actual temperature press and
release the temp recall button to see set-point temperature, display will show set-point temperature for 3 seconds then
revert back to actual temperature display.
Second, The temp recall button is used to change temperature display between Set-Point and Actual temperature.
Item (D) above describes how to change the display.
(G) DEFROSTING THE EVAPORATOR COIL: Your FWE R-AS-10 AIR SCREEN unit offers you smart auto defrosting.
Smart defrost is the factory default and requires you to do nothing, the defrost cycle is automatic. Sensors on the evapora-
tor coil read coil temperature and decide how long and how often your R-AS-10 unit requires defrosting. Depending on
usage and environment your R-AS-10 unit will defrost in intervals of 4, 6, 8, 10 and 12 hours.
During a defrost cycle the condensation from the evaporator coil will flow from the top of the unit down a drain line to the
condensate vapor pan. The condensate vapor pan will automatically evaporate all defrost condensation. There is no need
to empty a defrost water pan. Vapor can sometimes be visible and should be considered a normal operating condition.
Proper attention should be given to defrost your R-AS-10. Every "Event" or time the unit is used with door open, the coil
may build up ice reducing the effectiveness and overall operation of your R-AS-10.
