from the power cord aaches to
the starter relay and provides the
means to complete the electrical
circuit. So, a failure of the starter
relay can also look like a problem
not only with the compressor, but
also the condenser fan motor.
Before replacing a compressor, test
with a spare starter relay and over-
load that you can use for replacing
the exisng starter relay and over-
load.

b. This refrigerator is to be used and operated in an indoor seng that provides protecon from di-
rect exposure to rain, sunlight, and wind.
c. All power supplies used with this unit must have a properly grounded outlet that is compable with
the ground prong on the electrical plugs used with this refrigerator. The green color wire on the power
cord is the ground wire lead. Any electrical plug used with this refrigerator must match up its ground
prong with the green wire coming from the power cord. Failure to do so could result in damage to the
refrigerator and/or serious injury or death to the user.
d. Chemicals that are known to aack plasc, steel, vinyl, aluminum, and/or copper are not to be stored
in this refrigerator. Such use could severely damage the refrigerator and cause it to fail.
e. Flammable materials, or chemicals that react in a ammable or explosive nature when stored with
other chemicals are not to be stored in this refrigerator. Such use could result in serious injury or
death.
f. This refrigerator is NOT to be used or operated in atmospheres that are considered explosive, am-
mable, or of a hazardous locaon nature. Such use could result in serious injury or death.
g. The 500 VA transformer supplied with this refrigerator is for the exclusive use of supplying electrical
power to the refrigerator when a 230VAC power supply is available. Do NOT use it to supply electrical
power to any other electrical equipment. Such usage could result in damage to the transformer and
cause it to fail.
