– Loss of cooling could occur if the refrigerator operates in a noticeable out-of-level position for several
hours.
– It is not critical for the refrigerator to be level when traveling.
• Operating the refrigerator at high altitudes:
– When the refrigerator is operating on LP gas, reduced cooling performance and burner outage may occur
at elevations higher than 5,500 feet above sea level.
➤ Operate the refrigerator on electric power at altitudes higher than 5,500 feet.

– Refrigerator performance may be reduced in sub-zero temperatures. This temporary condition is normal
for absorption refrigerators.
