Location

These units are intended for indoor use only. Be sure the location

chosen has a floor strong enough to support the total weight of

the cabinet and contents. Units in this product line can weigh as

much as 1500 pounds when it is fully stocked. Reinforce the

floor as necessary to provide for maximum loading.

For the most efficient refrigeration, be sure to provide good air

circulation inside and out.

Inside cabinet: Do not pack unit so full that air cannot circulate.

Take care not to block air flow to the fans and allow space along

sides.

Outside cabinet: Be sure that the unit has access to ample

air. Avoid hot corners and locations near stoves and ovens. It

is recommended that the rear of the unit be no less than two

inches from any wall, partition or any other object which will

restrict exhaust air flow.

Leveling

A level cabinet looks better and will perform better because

the cabinet will not be subject to unnecessary strain due to

doors not properly lining up with door frames.

Some models have casters for ease of cleaning underneath and

for mobility. It is important that the unit be installed in a stable

condition with the front casters locked before operating. Locking

the front casters after installation is the operator’s responsibility.

Electrical connection

A standard self-contained unit is provided with a power cord

and three-prong grounded plug.

The unit should be plugged into a receptacle with its own

circuit protection that matches the amperage of the plug.

Refer to the amperage data on specifications

page or the serial tag data and your local code or

the National Electrical Code to be sure the unit is

connected to the proper power source. A protected

circuit of the correct voltage and amperage must

be run for connection to the unit.

The power supply must be disconnected

whenever performing maintenance or repairing

the equipment!

The unit must never be operated without the

louvered panel in place.

Built-in units

All self-contained units (MFSC) are tested at the factory to assure

proper operation. The unit should not be installed directly next to

high heat generating equipment (ranges, griddles, etc.).

These units are built into the counter from below and must be

supported from the bottom. The counter cut-out sizes and power

supply requirements are shown on the specifications page. All

refrigerators have drains located in the bottom of the tank. An

appropriate drainage area or container must be provided by

the customer. Be sure to place the unit so the pressure control,

located near the compressor, can be reached.

For installation of remote units (MF), consult a refrigeration

service company to connect refrigeration lines to the remote

condensing unit.

Self-contained refrigerated units (MFSC) require

air flow to the compressor. A louver is provided

and must be installed in the counter in front of the

condenser. An equal size opening at the rear of

the cabinet must also be provided to allow warm

air to escape. Failure to do so will void all product

warranties.

Free standing units

All self-contained units (N, N6/10/14, NDF, NLFAC, SCF and

NSCF) are tested at the factory to assure proper operation. The

unit should not be installed directly next to high heat generating

equipment (ranges, griddles, etc.).

These units are free standing, either on legs or casters. The

power supply requirements are shown on the specifications

page. All free standing units have drains located in the bottom

of the tank. An appropriate drainage area or container must be

provided by the customer.

Do not place the unit against a wall or any object that will block

air circulation through the condensing unit. If the unit must

be placed against a wall, leave a minimum of 2” of space for

air flow.
