meet ANSI / National Sanitation Foundation
®
(NSF
) Standard #7 requirements. Proper
installation is required to maintain certification.
Near the serial plate, each case carries a label
identifying the type of application for which
the case was certified.
ANSI/NSF-7 Type I - Display Refrigerator / Freezer
Intended for 75°F / 55% RH Ambient Application
ANSI/NSF-7 Type II - Display Refrigerator / Freezer
Intended for 80°F / 55% RH Ambient Application
ANSI/NSF-7 - Display Refrigerator
Intended for Bulk Produce
HUSSMANN PRODUCT CONTROL
The serial number and shipping date of all
equipment is recorded in Hussmann’s files
for warranty and replacement part purposes.
All correspondence pertaining to warranty or
parts ordering must include the serial number
of each piece of equipment involved. This is
to ensure the customer is provided with the

displaying products in air conditioned stores
where temperature is maintained at or below
the ANSI / NSF-7 specified level and relative
humidity is maintained at or below 55%.
Recommended operating ambient
temperature is between
65°F (18°C) and 75°F (23.9°C).
Maximum relative humidity is 55%.

HUSSMANN CORPORATION • BRIDGETON, MO 63044-2483 U.S.A.
Placing refrigerated merchandisers in direct
sunlight, near hot tables or near other heat
sources could impair their efficiency. Like
other merchandisers, these merchandisers are
sensitive to air disturbances. Air currents
passing around merchandisers will seriously
impair their operation. Do NOT allow air
conditioning, electric fans, open doors or
windows, etc. to create air currents around
the merchandiser.

SELF CONTAINED (LOCATION)
NAV and NAVC merchandiser models have
front-facing condenser air intake and air
discharge. Maintain a minimum clearance
distance of 2 feet in front of the merchandiser
and 4 inches on each side, so that air discharge
and air intake are not obstructed.

Do not remove the shipping skid until the
merchandiser is near its final location.
The skid provides protection for both the
merchandiser and the floor.
Remove the skid by raising one end of the
merchandiser approximately 6 inches. Block
the merchandiser securely, and remove the two
skid bolts from the raised end. Replace the
bolts with (provided) leg levelers. Repeat this
procedure at opposing end. Once the leg levelers
are secured in place, the merchandiser may be
slid off the skid and placed in its final location.
DO NOT TILT MERCHANDISER ON ITS
SIDE OR END WHEN REMOVING SKID.
Once the skid is removed, the merchandiser
must be lifted —NOT PUSHED— to reposition.
Check floor where merchandisers are to be set
to see if it is a level area. Determine the highest
part of the floor.

The serial plate is located in the top interior at
the left side of the merchandiser. It contains all
pertinent information such as model, serial
number, amperage rating, refrigerant type
and charge. This information will be needed
to maintain, service or order parts for the
merchandiser.

SEALING MERCHANDISER TO FLOOR
If required by local sanitary codes, or if the
customer desires, merchandisers may be sealed
to the floor using a vinyl cove base trim. The
size needed will depend on how much variation
there is in the floor, from one end of the
merchandiser to the other. Sealing of the lower
front and rear panels on self contained models
may hamper their removal for servicing or
maintenance of the condensing unit.
NOTE: Do not allow trim to cover any intake
or discharge grilles located in the lower front
panel.

ELECTRICAL / REFRIGERATION
MERCHANDISER ELECTRICAL DATA
Refer to Appendix A of this manual or the
merchandiser’s serial plate for electrical
information.
FIELD WIRING
Field wiring must be sized for component
amperes stamped on the serial plate. Actual
ampere draw may be less than specified.
ALWAYS CHECK THE SERIAL PLATE
FOR COMPONENT AMPERES
ELECTRICAL CONNECTIONS
All wiring must be in compliance with NEC
and local codes.
ELECTRICAL OUTLET:
Before the merchandiser is connected to any
wall circuit, use a voltmeter to check that the
outlet is at 100% of the rated voltage. The wall
circuit must be dedicated for the merchandiser. Failure to do so voids the warranty. Do
not use an extension cord. Never plug in more
than one merchandiser per electrical circuit.
• Always use a dedicated circuit with the
amperage stated on the unit.
• Plug into an outlet designed for the plug.
• Do not overload the circuit
• Do not use long or thin extension cords.
Never use adapters.
• If in doubt, call an electrician.
POWER INPUT
NAV / NAVC merchandisers are provided
with 3-Amp power receptacles. E
equipment connected to the receptacle
must not exceed 3 amps. The receptacle is in
lectrical
series with a GFCI safety device.
NAV / NAVC merchandisers do not have a
power switch. Once power cord is connected
to power, the merchandiser is energized.
The refrigeration thermostat has an OFF
position that disconnects power to the
condensing unit only.
Risk of Electric Shock. If cord or plug
becomes damaged, replace only with
a cord and plug of the same type.

— LOCK OUT / TAG OUT —
To avoid serious injury or death from electrical shock, always disconnect the electrical
power at the main disconnect when servicing
or replacing any electrical component. This
includes, but is not limited to, such items as
doors, lights, fans, heaters, and thermostats.
Merchandiser must be grounded.
Do not remove the power supply cord ground.
