LP GAS SYSTEM
Leak testing can be accomplished using an electronic leak
detector or a commercial grade leak test solution. The use
of home made soap and water leak test solution should be
avoided if possible. When applying leak test solutions, apply
the solution over the entire joint using a small brush or spray
applicator.
Due to low system operating pressure, it may take a few
minutes for bubbles to appear if the connection is leaking.
Hidden joints should be examined thoroughly using an
inspection mirror.
Fig. 8 - LP Gas System Components.
The refrigerator LP gas system, shown in Fig. 8, is for propane
gas use only. The system working pressure is 10.5 to 11.5
in. water column. Propane gas pressures below 10.5 in. w.c.
or above 11.5 in. w.c. will affect heat output which in turn will
affect cooling effi ciency.

WARNING:
When working on or near the LP gas system:
• Do not smoke or light fi res! Extinguish all open fl ames!
• Do not use an open fl ame to leak test any of the LP gas
system components. LP gas is highly fl ammable and
explosive.
• Do not connect the refrigerator directly to the LP gas
tank. Always use an approved pressure regulator
between the LP gas tank and the refrigerator LP gas
system.
• To prevent damage to connections, piping, and
components, always use two wrenches to tighten or
loosen connections. Damaged connections, piping, and
components create the potential for gas leaks.
!
CAUTION:
Do not use leak test solutions that contain ammonia
or chlorine. Ammonia and chlorine attack copper and
brass components.
!
WARNING:
Do not wet or spray liquids on or near electrical
connections or electronic components. Many liquids,
including leak detection solutions, are electrically
conductive and can create an electric shock
hazard, short electrical components, and/or damage
electronic circuits.
