Manyproductmodelsaredesignedtooperate
inharshoutdoor/marineenvironments.Speial
considerationsincludethefollowing:
 • Theunitsaredesidnedtooperatebetween
50°F(10°C)and110°F(40°C).Highambient
temperatures(110°Forhigher)mayreduce
theunit’sabilitytoreachlowtemperatures
andmayalsoreducetheiceproductionrate
forthosemodelswithicemakers.
 • Iftheambienttemperatureisexpectedto
dropbelow45°F,drainallwaterfromtheunit

DANGER
Electrocution can cause death or serious injury.
Burns from hot or cold surfaces can cause serious
injury. Take precautions when servicing this unit.
• Disconnect the power source.
• Do not stand in standing water when working
around electrical appliances.
• Make sure the surfaces you touch are not hot or
frozen.
• Do not touch a bare circuit board unless you are
wearing an anti-static wriststrap that is
grounded to an electrical ground or grounded
water pipe.
• Handle circuit boards carefully and avoid
touching components.
Figure 1
To measure the start winding resistance measure across
the C and S pins.
To measure the run winding resistance measure across the
C and R pins.
Also check S to R and you should get the sum of the run
and start windings.
To ensure the windings are not shorted check the S and R
to ground.
