TEMPERATURE SELECTOR

The temperature selector on the refrigerator controls both the gas and electric operation, thereby
eliminating the necessity of resetting each time a different energy source is employed.
After the initial start-up, the temperature selector should be moved from "COLDEST" to the desired
temperature setting, which is usually about mid-setting.
TO SHUT OFF THE REFRIGERATOR
The refrigerator may be shut off while in any mode of operation by pressing the main power ON/OFF button
(1) to the UP (OFF) position. This shuts off all DC power to the refrigerator, including the interior light.

the GAS mode.
If the CHECK indicator lamp (D) illuminates and the GAS mode indicator lamp (C) is off, the controls have

ON/OFF button (1) to the OFF then ON position. (See Step 2 under GAS MODE). Press the
TEMPERATURE SELECTOR button (3) until the lamp at the desired position is illuminated.
