Thetford 1200 Series AC With Cooling Unit Sensing Capabilities - Manual (Page 7)

Owner’s Manual 7
Operating the Refrigerator Controls
AC Operation 120 volts AC
(108 volts min.-132 volts max.)
12 volts DC - control voltage
(10.5 volts min. - 15.4 volts max.)
The refrigerator operates on these energy sources. Operation
out of these limits can damage the refrigerator electrical
components and will void the warranty.
Control panel:
The refrigerator control panel (See Art01333) is between the
freezer compartment and the fresh food compartment. To
maintain the operating control functions of the refrigerator, a 12
volt DC power supply is necessary. The refrigerator receives
DC power from the 12 volt system of the vehicle; either an
auxillary battery, a converter, or the vehicle engine battery.
The ON / OFF button [30] starts and shuts down the refrigerator:
- To turn on the refrigerator, push and release the ON / OFF
button.
- To turn off the refrigerator, push the ON / OFF button for one
second and then release.
The SET TEMP button [32] controls the temperature adjustment
of the freezer and the fresh food compartment.
- Push the SET TEMP button and the temperature setting (the
numbers “1-9”) show in the center display [33].
- The number “9” is the coldest temperature setting.
- Push and hold the SET TEMP button and the temperature
setting changes.
- Release the SET TEMP button when the temperature
setting that you wish appears.
- After ten seconds, the temperature setting will go out and
only a green power ON light remains.
NOTE: Push and release the MODE button [4] to show “AC”,
the current mode of operation, in the center display
for 10 seconds.
- If 120 volts AC is not available to the refrigerator:
- The fault codes “no” “AC” shows in the center display
and an audible alarm sounds.
If 120 volts AC is available to the refrigerator, but is not operating
correctly:
- A fault code shows in the center display.
- An audible alarm starts.
- Refer to the “Fault Codes” section of this manual.
Ice Maker (Optional)
The ice maker is assembled to the refrigerators at the factory as
optional equipment. If the refrigerator does not have a factory
installed ice maker, one cannot be added to the refrigerator at a
later time.
The ice maker is fully automatic and will operate in ambient
temperatures as low as 0° F. To allow operation at tempera-
tures between 0° F and 32° F., the ice maker has a heater on
the solenoid water valve and on the water line between the
solenoid valve and the ice maker. At temperatures below 0° F,
store the ice maker as written in the “Ice Maker Storage” section
of this manual.
CAUTION: The water line heater does not protect the
water supply line from the vehicle shut off valve to the
solenoid valve on the back of the refrigerator.
When the freezer temperature of the refrigerator is low enough,
the ice maker opens the water solenoid valve and fills the mold.
The ice maker ejects the frozen ice into a storage bin. As the
storage bin fills, the ice raises the shut-off arm until it turns off
the ice maker. As you use the ice and lower the ice level in the
storage bin, the shut-off arm also lowers. This turns the ice
maker ON and begins the process of making ice.
The ice maker operates on:
- Cold potable water at a pressure of 15 psi - 125 psi.
- 120 Volts AC (108 VAC min. - 132 VAC max.).
Ice maker operation:
1. Make sure the ice maker AC power cord is plugged into a
receptacle.
2. Open the water shut off valve of the vehicle.
NOTE: Make sure that the ice maker arm can move freely and
does not touch the frozen foods in the freezer.
