Effects of High Altitude on Propane Gas
Operation
When you operate the refrigerator on propane gas at altitudes
higher than 5500 feet above sea level:
- You may experience reduced cooling performance of the
refrigerator.
- You may experience burner outages.
To avoid these possible problems, Norcold recommends that
you operate the refrigerator on AC when at altitudes higher than
5500 feet above sea level.
If you reset the controls and the fault occurs again before the
refrigerator completes a full cooling cycle:
- The heat sources to the cooling unit are turned off and are
locked out.
- An audible alarm starts.
- A fault code “no” “co” shows in the Center display.
- This time you can not reset the fault. Have the refrigerator
serviced by your dealer or a Norcold authorized Service
Center as soon as possible.
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 (white) 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.
3. Push the ice maker arm down to the ON position [1] (See
Art01015).
CAUTION: If you operate the refrigerator without
connecting the water supply line and/or opening the
water shut off valve of the vehicle, make sure the ice
maker arm is up in the OFF position.
4. Allow the freezer to cool enough and ice production will begin
to fill the storage bin [2].
NOTE: New plumbing connections and/or impurities in the
water supply line after winterizing can cause the first
ice to be discolored or have an odd flavor.
5. To stop the ice maker, push the ice maker arm up to the OFF
position [3].
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.
Refrigerator Care Checklist
Your refrigerator will give you years of trouble free service if you
do these simple checks every three to six months:
- Keep the food compartment and the freezer clean. See
“Cleaning”.
- Defrost the refrigerator as necessary. See “Defrosting”.
- Make sure the door seals correctly. See “Door Sealing“.
- Be aware of any cooling changes that are not because of
weather, loading, or gas control changes. If changes occur,
contact your dealer or service center.
