GROUND FAULT CIRCUIT INTERRUPTER
Ground Fault Circuit Interrupter (GFCI/GFI) protection is
a system that shuts down the electric circuit (opens it)
when it senses an unexpected loss of power, presumably
to ground. Manitowoc does not recommend the use of
GFCI/GFI circuit protection to energize our equipment.
If code requires the use of a GFCI/GFI then you must
follow the local code. The circuit must be dedicated, sized
properly and there must be a panel GFCI/GFI breaker. We
do not recommend the use of GFCI/GFI outlets to energize
our equipment as they are known for more intermittent
nuisance trips than panel breakers.

the stainless steel to avoid marring the finish. If a greasy
residue persists, use a damp cloth rinsed in a mild dish soap
and water solution. Wipe dry with a clean, soft cloth.
Never use steel wool or abrasive pads for cleaning. Never
use chlorinated, citrus based or abrasive cleaners.
Stainless steel has a clear coating that is stain resistant and
easy to clean. Products containing abrasives will damage
the coating and scratch the panels. Daily cleaning may be
followed by an application of stainless steel cleaner which
will eliminate water spotting and fingerprints. Early signs of
stainless steel breakdown are small pits and cracks. If this
has begun, clean thoroughly and start to apply stainless

In order to maintain proper refrigeration performance, the
condenser fins must be cleaned of dust, dirt and grease
regularly. It is recommended that this be done monthly. If
conditions are such that the condenser is totally blocked
in a month, 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.
Failure to maintain a clean condenser coil can initially cause
high temperatures and excessive run times. Continuous
operation with a dirty or clogged condenser coil can
result in compressor failure. Neglecting the condenser coil
cleaning procedures will void any warranties associated
with the compressor and cost to replace the compressor.
N225 & N227 DEFROSTING
Mechanically cooled freezers should be defrosted after 3/8”
of ice accumulation. To defrost disconnect power to the
equipment or turn the thermostat knob to the OFF position.
Never use sharp objects or tools to clean or scrape ice/frost
build up from the refrigerated cold pans. A puncture could
cause irreparable damage to the refrigeration system.
