INSTALLATION

NSF CERTIFICATION

These merchandisers are manufactured to
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

Placing refrigerated merchandisers in direct
sunlight, near hot tables or near other heat
sources could impair their efficiency. Like
other merchandisers, these self-contained units
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 case. BCH units take in air and exhaust

air through the front of the case, and require
no clearance space on top, at the back or either
side. Product should always be maintained at

proper temperature. This means that from the
time the product is received, through storage,
preparation and display, the temperature of
the product must be controlled to maximize
the life of the product.

For California Businesses:

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
correct parts.

LOCATION

These merchandisers are designed for
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) with a maximum
55% relative humidity to 80 F (26° C) with a
maximum 55% relative humidity.

This product may contain chemicals known

to the State of California to cause cancer,
birth defects, or other reproductive harm.

This warning is the result of the California State
law known as the California Safe Drinking Water
and Toxic Enforcement Act of 1986, which is
commonly referred to as “Proposition 65.”

This warning does not mean that Hussmann
products will cause cancer or reproductive
harm, or is in violation of any product-safety
standards or requirements. As claried by the
California State government, Proposition 65
can be considered more of a ‘right to know’ law
than a pure product safety law. When used as
designed, Hussmann believes that our products
are not harmful. We provide the Proposition 65
warning to stay in compliance with California
State law. It is your responsibility to provide
accurate Proposition 65 warning labels to your
customers when necessary. For more information
on Proposition 65, please visit the California
State government website.

UNLOADING

Unloading from Trailer:

Lever Bar (also known as a Mule, Johnson

Bar, J-Bar, Lever Dolly, or Pry Lever)

Move the merchandiser as close as possible
to its permanent location and remove
all packaging. Check for damage before
discarding packaging. Remove all separately
packed accessories such as kits and shelves.

Improper handling may cause damage to
the merchandiser when unloading. To avoid
damage:

1. Do not drag the merchandiser out of the

trailer. Use a Johnson bar (Mule).

2. Use a forklift or dolly to remove the

merchandiser from the trailer.

SHIPPING SKID

Each merchandiser is shipped on a skid to
protect the merchandiser’s base and to make
positioning the case easier.

Remove the top of the crate and detach
walls from each other. Lift crate from the
skid. Unscrew the case from the skid.
The merchandiser can now be lifted off the
crate skid. Lift only at base of skid! Remove
any braces and/or skids attached (blanket
wrapped merchandiser may have skids).

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. To remove the skid, remove screws
attaching skid to the merchandiser.

Check floor where merchandisers are to be set
to if it is a level area.

Do not walk or put heavy objects on case.

EXTERIOR LOADING

Do NOT walk on top of the merchandiser or

damage to the merchandisers and serious
personal injury could occur.

merchandisers are not structurally
designed to support excessive external
loading such as the weight of a person. Do

not place heavy objects on the merchandiser.

Do NOT remove shipping crate until the

merchandiser is positioned

for installation.

SHIPPING DAMAGE

All equipment should be thoroughly examined
for shipping damage before and during
unloading. This equipment has been carefully
inspected at our factory. Any claim for loss
or damage must be made to the carrier.
The carrier will provide any necessary
inspection reports and/or claim forms.

Apparent Loss or Damage

If there is an obvious loss or damage, it must
be noted on the freight bill or express receipt
and signed by the carrier’s agent; otherwise,
carrier may refuse claim.

Concealed Loss or Damage

CABINET LEVELING

This merchandiser must be installed level

(from back to front, and side to side) to allow
maximum draining of the condensate water as
well as proper door alignment and operation.
Choose a level area to install case.

BCH-8S and BCH-18 cases have one
adjustable cabinet foot at each bottom corner
for easy adjustment if required. BCH-45
and BCH-68 also have an adjustable foot at
center front and back. Turn the foot levelers
clockwise to add length to each foot for
leveling.

When optional 6-inch legs are used, screw the
legs tight to the merchandiser base and then
adjust the feet.

Adjustable Foot

When optional casters are used, screw them
tight to the merchandiser base. Once in final
position, lock each caster.

Thumbscrew Lock

Lock Each Caster

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.

To adjust the torque applied to the hinged
door:

1. Place a wrench on each of the two lower

support nuts located at the bottom hinge.

2. Loosen the lower nut while holding the

upper nut in place.

3. Torque is increased or decreased by
rotating the top nut. After adjustments are
made, tighten the bottom nut while holding the
upper nut in place. Torque bottom nut to a
minimum of 20 ft-lb.

SERIAL PLATE LOCATION

The serial plate is located at the interior left
side of the merchandiser’s cabinet. It contains
all pertinent information such as model, serial
number, amperage rating, refrigerant type and
charge.

REFRIGERATION UNIT ACCESS

The merchandiser’s front grille has two
screws, which must be removed from either
end at the top of the panel. The lower front
panel may be removed by lifting the panel
straight upward and over the tabs on which it
is hanging. The panel is installed by reversing
the above procedure. Ensure lower front
panel is connected to the bottom brackets to
prevent interference with door and to avoid air
circulation problems.

ELECTRICAL / REFRIGERATION

• BCH-8S and BCH-18 require a dedicated
15 AMP/115V circuit with grounded wall
receptacle (NEMA 5-15R).

• BCH-45 and BCH-68 require a dedicated

Merchandiser must be grounded.

Do not remove the power supply cord ground.

REFRIGERATION

BCH merchandisers are equipped with a
hermetic compressor. The condenser is of fin
and tube construction. The air is taken into
the merchandiser from the front of the cabinet
and is also discharged from the front. See
page 1-2 for details. BCH models use R-134A
refrigerant. The systems employ capillary tubes
for refrigerant flow. The capillary tube is soldered
to the suction line pull-out coil for proper heat
exchange. If the capillary tube should become
plugged or damaged, it is better to replace the
heat exchanger (capillary tube and suction line).

20 AMP/115V circuit with a grounded wall
receptacle (NEMA 5-20R).

• 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.

If the power supply oscillates beyond the range
given in the following table, a voltage regulator
is required.

PLUG

The plug cord is 7 ft long and is located on
the right hand rear of the merchandiser.
Disconnect power before servicing. BCH
merchandisers require a dedicated electrical
circuit with ground. 12AWG is the minimum
sized acceptable wire.

— 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.

OPERATING Safe-NET III CONTROLS

The Safe-NET III electronic temperature and
defrost controller is located in the cassette
compartment. The controller comes factory set
at position #5 and is ready to go.

Safe-NET III Controller Location

The front grille must be removed in order to
access this control. To remove the grille, open
the door and remove the two plastic screws
and retainers on the top of the grille, then tilt
out and lift up to remove.

The temperatures can be adjusted by rotating
the knob counter-clockwise for a warmer
setpoint, or clockwise for a colder setpoint.
The display shows the setpoint for a few
seconds when changed, then reverts to showing
the sensed temperatures in the merchandiser.

The adjustment knob allows the user to
select a pre-configured cold setpoint, warm
setpoint or any setpoint within this range. The
adjustment knob is also configured with

O

n functionality to power off the controller.

START-UP / OPERATION

The defrost cycle is initiated at power on.
(This cycle will quickly terminate on the
initial start-up of a warm merchandiser.)
Another defrost cycle will follow every 8 hours
thereafter. The defrost times will reset whenever
power is interrupted. Therefore, the standard
defrost times can be reset by interrupting power
(full stop, then start) at the desired time.
This will reset the initial time and restart the
8-hour cycle.

Troubleshooting

During the compressor-on time (1 minute),
or compressor-off time (2 minutes), built-in
protection time will delay the defrost initiation.

If you force a defrost cycle during this time,
the feature will initiate but not start until the
compressor protection mode times out.

ALARMS AND CODES

Safe-NET III is available with an audible
alarm (located in the display module) that
sounds in the event a failure occurs.

cleaN light shields. Never use abrasive
cleaNsers or scouriNg pads.

The interior surfaces may be cleaned with most
domestic detergents and sanitizing solutions
with no harm to the surface.

Product must be stored in a cooler when
product is removed from merchandiser for
cleaning.

Do NOT Use:

•Abrasive cleansers and scouring pads, as these
will mar the finish.

•Coarse paper towels on coated glass.

•Ammonia-based cleaners on acrylic parts.

Do not use HOT water on COLD glass surfaces.
This can cause the glass to shatter and could
result in personal injury. Allow glass fronts,
ends and service doors to warm before applying
hot water.

fan motors and cleaning or rinse water.

•Do NOT flood merchandiser with water.

do Not use steam or high water

Cleaning Coils

To maintain peak operating efficiency, the coil
should be cleaned at least once each month.
A dirty coil slows product cooling significantly
and increases energy consumption by as much
as 20%. Dirt buildup on coils can also cause
the compressor to lock up damaging the
condensing unit.

• Remove screws on top of each side of the
louvered grille, then lift off the grille.

• Next, detach the merchandiser’s electrical
wire harness located on the right or left hand
side near the coil.
