Section 2 Installation

Electrical Service

DANGER

Check all wiring connections, including factory

terminals, before operation. Connections can become

loose during shipment and installation.

Warning

This appliance must be grounded and all field wiring

must conform to all applicable local and national

codes. Refer to rating plate for proper voltage. It is the

responsibility of the end user to provide the disconnect

means to satisfy the authority having jurisdiction.

VOLTAGE

All electrical work, including wire routing and grounding,

must conform to local, state and national electrical codes.

The following precautions must be observed:

• The equipment must be grounded.

• A separate fuse/circuit breaker must be provided for

each unit.

• A qualified electrician must determine proper wire size

dependent upon location, materials used and length

of run (minimum circuit ampacity can be used to help

select the wire size).

• The maximum allowable voltage variation is ±10% of

the rated voltage at equipment start-up (when the

electrical load is highest).

• Check all green ground screws, cables and wire

connections to verify they are tight before start-up.

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.

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.

Caster Installation

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.

Warning

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.

Warning

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.

2. Located at each caster mounting location are 4 bolts,

for a total of 16. Remove them.

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.

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.

MF Series Operation

MF series remote models will require a connection to a

separate refrigeration system.

LOADING: MF SERIES

To load, place a complete layer of cartons or bottles

standing upright on the load tray. Then place a divider tray

on top of this layer, then another layer of cartons or bottles

on this tray, then another tray and another layer, etc. As

each additional tray is loaded, the elevators gradually lower.

The last layer may be placed on top without the use of

another tray. When loading the average tall half pint bottles,

four layers may be loaded into each compartment standing

upright and the fifth layer laying down.

Important

It is very important to use the divider trays provided

between each successive layer of contents to assure the

correct balance of the load and the proper action of the

elevating mechanism.

Wire racks, when used, should be loaded completely. When

placing one rack on top of the other, be sure the stacking

lugs are properly aligned.

LOADING: N6/10/14 SERIES

These cabinets are designed to dispense 13” x 13” x 11”

(33cm x 33cm x 28cm) high (maximum dimensions) dairy

cases. Place one case loaded with milk on the carrier and

then place a second case loaded with milk on top of the

first case. Press down on the cases leaning them toward

the retaining bracket located under the top lid track, then

gradually release pressure on the cases so that the top edge

of the case engages with the retaining bracket.

The elevating mechanism is designed to keep the contents

several inches below the top of the cabinet when fully

loaded. This distance serves two purposes:

A. It keeps the top layer of milk completely refrigerated

even when the lids are removed.

B. It insures that the lids will operate without striking the

contents as successive layers are added.

LOADING: NDF SERIES

These cabinets are designed to dispense 13” x 13” x 11”

(33cm x 33cm x 28cm) high (maximum dimensions) dairy

Maintenance Section 4

INTERIOR CLEANING

Note

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.

Note

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.

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.

Note

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.

Self-Contained Units Evaporator Maintenance

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.

Part Number: 9291482 05/16 19

Section 4 Maintenance

EXTERIOR CLEANING

Note

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.

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.

Defrosting

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.
