Operation - Models N225, N225L, N227 And N227L
After installation, the unit will begin operating simply
by plugging it into the proper outlet. If the unit does
not operate after being plugged in, check to see if the
thermostat is in the OFF position.
The models 225 and 227 are designed to hold
frozen products at a temperature range of 5°F to
-5°F (-15°C to -21°C). The thermostat is located in
the machine compartment.
Maintenance - Models N225, N225L, N227 And N227L
In order to maintain proper refrigeration performance,
the condenser ns must be cleaned of dust, dirt and
grease every three months. If conditions are such that
the condenser is totally blocked in three months, the
frequency of cleaning should be increased.
Clean the condenser with a vacuum cleaner or stiff
brush. If extremely dirty, a commercially available
condenser cleaner may be required.
Defrosting must be done manually after 3/8” of ice
accumulation. To defrost disconnect power to the
equipment or turn the thermostat knob to the OFF
position.
The lid should be cleaned regularly with a soft
cloth or sponge and solution of soap and water to
maintain it’s ability to seal properly.
Maintenance - Models 203, 204, 204P, 240, 242, 248, 250, 305 And 307
The interior and exterior of these models may be cleaned
using soap and warm water. If this is not sufficient, try
ammonia and water or a non-abrasive cleaner. Be sure
to rinse thoroughly with clean water after using ammonia
or a cleaner. When cleaning the exterior, always rub
with the “grain” of the stainless steel to avoid marring
the nish.
Do not use an abrasive cleaner. Abrasive
cleaners will scratch the stainless steel
and plastic.
