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.

DANGER
Legs or casters must be installed and the legs or casters
must be screwed in completely to prevent bending.
When casters are installed the mass of this unit will
allow it to move uncontrolled on an inclined surface.
These units must be tethered/secured to comply with
all applicable codes.
nWarning
The unit must be installed in a stable condition with
the front wheels locked. Locking the front casters after
installation is the owner’s and operator’s responsibility.
nWarning
Use a jack to lift the refrigeration unit off the ground
just far enough to remove the caster. Place blocking
underneath the unit. Do not work underneath a raised
unit without proper blocking. Do not lift the unit more
than necessary to remove the caster. Lifting the unit too
far can make the unit unstable.
1. Carefully place the unit on its back.
NOTE: * BTU is with lids closed.
2. Located at each caster mounting location are 4 bolts,
for a total of 16. Remove them.
For installation of remote MF series units, consult a
refrigeration service company to connect refrigeration lines
to the remote condensing unit.
3. Place a locking plate caster over one of the front holes,
matching the 4 mounting holes to the pre-drilled holes
in the underside of the unit. Insert 4 bolts and tighten.
Drain Connections
nWarning
If a mechanically cooled refrigerated base does not have
a condensate evaporator supplied, you must connect
the condensate line to a suitable drain. Otherwise, water
will collect on the floor, causing a potentially hazardous
situation.
4. Repeat step 3 with the other three casters.
5. Carefully lift the unit upright.
,Caution
After installing casters, the unit must stand upright for
twenty-four (24) hours before being powered up to
assure oil return to the compressor sump.
nWarning
Moisture collecting from improper drainage can create a
slippery surface on the floor and a hazard to employees.
It is the owner’s responsibility to provide a container or
outlet for drainage.
All refrigerators have drains located in the bottom of the
tank. An appropriate drainage area or container must be
provided by the owner.

INTERIOR CLEANING
Self-Contained Units Evaporator Maintenance
Not
When cleaning interior and exterior of unit, care should
be taken to avoid the front power switch and the rear
power cord. Keep water and/or cleaning solutions away
from these parts.
Not
Never use a high-pressure water jet for cleaning or hose
down or flood interior or exterior of units with water. Do
not use power cleaning equipment, steel wool, scrapers
or wire brushes on stainless steel or painted surfaces.
The interior can be cleaned using soap and warm water. If
this isn’t sufficient, try ammonia and water or a nonabrasive
liquid cleaner.
Each unit has a drain located inside the unit that removes
the condensation from the evaporator coil and routes it
to an external condensate evaporator pan. Each drain can
become loose or disconnected during normal use. If you
notice water accumulation on the inside of the unit, be sure
the drain tube is connected to the evaporator drain pan.
If water is collecting underneath the unit, make sure the
end of the drain tube is in the condensate evaporator. The
leveling of the unit is important as the units are designed to
drain properly when level. Be sure all drain lines are free of
obstructions.
Remote Units Evaporator Maintenance
The stainless steel condensate evaporator pan should be
cleaned monthly. Use a vacuum cleaner or damp cloth to
remove dust that may have accumulated. This will prevent
corrosion of the stainless steel.
To help prevent corrosion of the evaporator coil, store all
acidic items, milk is slightly acidic, in seal-able containers.
Immediately wipe up all spills.
Cleaning the NLFAC milk dispensers
This instruction applies to the model NLFAC dispenser only.
A drain is supplied to simplify cleaning of the interior. Open
the drain tube clamp. Drain accumulated liquid from the
cabinet. Be sure to re-clamp the tubing before resuming
operation of the NLFAC unit.
After cleaning the interior and exterior as described, be sure
to return the milk case loading tray to the bottom of the
unit. The load tray is required not only for easy self-locating
of milk cases, but it also ensures proper air flow through the
evaporator coil for the air curtain.
Not
Any restriction to the air flow path, including leaving
the milk case load tray out of the cabinet, will result in
the voiding of your warranties.

Part Number: 9291482 05/16
Section 4
Maintenance
EXTERIOR CLEANING
Defrosting
Not
Never use an acid based cleaning solution on exterior
panels! Many food products have an acidic content,
which can deteriorate the finish. Be sure to clean the
stainless steel surfaces of ALL food products.
Clean the area around the unit as often as necessary to
maintain cleanliness and efficient operation.
Wipe surfaces with a damp cloth rinsed in water to remove
dust and dirt from the outside of the unit. Always rub with
the “grain” of 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 exterior panels have 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 steel cleaners in attempt to
restore the steel.
Milk or Ice Cream dispensers require defrosting after 3/8” of
frost forms. On/Off switch is located above the louver panel.
Never use sharp objects or tools to clean or scrape ice/frost
build up from the refrigerated cold pans. A puncture to the
pan could cause irreparable damage to the refrigeration
system.
CLEANING THE CONDENSER COIL
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.
Gasket Maintenance
Gaskets require daily cleaning to prevent mold and mildew
build up and also to retain the elasticity of the gasket.
Gasket cleaning can be done with the use of warm soapy
water. Avoid full strength cleaning products on gaskets as
this can cause them to become brittle and crack. Never use
sharp tools or knives to scrape or clean the gasket. Gaskets
can be easily replaced and do not require the use of tools
or an authorized service person. The gaskets are “Dart” style
and can be pulled out of the groove. Soak new gaskets in
warm water to make them more pliable. Dry and “press”
back into place.
Casters
Wipe casters with a damp cloth monthly to prevent
corrosion.
