LOCATION
These merchandisers are designed for displaying
products in air conditioned stores where tempera-
ture is maintained at or below 75°F (24°C) and
relative humidity is maintained at or below 55%.
Placing refrigerated merchandisers in direct sun-
light, near hot tables or near other heat sources
could impair their efficiency.
Like other merchandisers, these are sensitive to air
disturbances. Air currents passing around mer-
chandisers will seriously impair their operation.
Do NOT allow air conditioning, electric fans,
open doors or windows, etc. to create air currents
around the merchandisers.
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.

The top cylinders, which allow the raising and
lowering of this glass, have been carefully
installed and tested for the proper tension before
shipment. However, during shipment and storage,
the lubricant inside the cylinders may have settled.
This settling can cause excessive or uneven ten-
sion on the glass to the point of breakage.
To avoid any damage, please do the following
before completely raising the front glass.
1. Slowly raise and lower each glass section
6 times to a height of 6 in. (152 mm).
2. Increase the height to about 12 in. (305
mm) and raise and lower the glass 6 times.
3. Then raise the glass to the full extension
and lower.
This should release any settled lubricant in the
cylinders and prevent any stress on the front
glass.
Read before raising front glass.

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 case.
MERCHANDISERS SHIPPED
WITH END INSTALLED
If the case was shipped with the end installed, two
long bolts were used to hold the shipping brace to
the end. If the shipping bolts are reinserted after
removing the brace, they will extend into the
product area. Therefore, be sure to replace these
bolts with the shorter bolts provided. Refer to the
detailed information provided in the separate
End Kit Instruction shipped with each end.
Note: Be careful not to damage the factory
installed end while moving the case. Make sure
that tools are positioned past the end and beneath
the merchandiser’s support bar.
SHIPPING BRACES
Move the fixture as close as possible to its perma-
nent location and then remove all packaging and
shipping braces. Check for damage before dis-
carding packaging. Remove all separately packed
accessories such as kits, and shelves.
Remove all nut retainers used with shipping
braces.
SHIPPING RIDER
Each case is shipped on a rider to protect factory-
installed legs, and to make positioning the case
easier. Remove the rider after the case has been
positioned.
Note: Once the rider is removed, the case must
be lifted –NOT PUSHED– to reposition.
To remove the rider, remove screws attaching
each leg to rider. Remove screws holding rider
cross-members, then slide cross-members out
from between sides. Once cross-members are out,
slide the sides out.
1-2 INSTALLATION
P/N 406928

LEVELING
Merchandisers must be installed level to
ensure proper operation of the refrigeration
system and to ensure proper drainage of
defrost water.
Set a long level (4 ft [1220 mm] or more) on
the upper front panel of the merchandiser.
Use an open-end wrench to turn leg levelers
until the merchandiser is level from end to
end and from front to back. Check all 6 legs
on 8 ft (2438 mm) cases, or 8 legs on 12 ft
(3658 mm) cases.

P/N 420057

REFRIGERANT
The correct type of refrigerant will be stamped on
each merchandiser’s serial plate. The case refrig-
eration piping is factory sealed, pressurized and
leak tested. Before making refrigeration hookups,
depress universal line valve to ensure that coils
have maintained pressure during shipment.
REFRIGERANT PIPING
Connection Location
The refrigerant line connections are at the right-
hand end of the merchandiser (as viewed from the
front) beneath the display pans. A sticker marks
the location of the connection “pod.” The installer
must saw a hole through the pod to exit the case.
After connections have been made, seal this outlet
thoroughly. Seal both the inside and the outside.
We recommend using an expanding polyurethane
foam insulation.
Multiplexing
Piping of merchandisers operating on the same
refrigeration system may be run from merchan-
diser to merchandiser. DO NOT RUN REFRIGERANT
LINES THROUGH MERCHANDISERS THAT ARE NOT
ON THE SAME REFRIGERATION SYSTEM BRANCH as
this may result in poor refrigeration control and
compressor failure.
Interconnecting piping inside the merchandiser
must be located as shown below to allow room for
lifting the hinged fan plenums and for clearance
beneath the display pans. The interconnecting
piping may be run outside the case.
Line Sizing
Refrigerant lines should be sized as shown on the
refrigeration legend that is furnished for the store
or according toASHRAE guidelines. Refer to the
information on the next page for branch line
piping of Hussmann Equipment.
Oil Traps
P-traps (oil traps) must be installed at the base of
all suction line vertical risers.
Pressure Drop
Pressure drop can rob the system of capacity. To
keep the pressure drop to a minimum, keep the
refrigerant line run as short as possible using a
minimum number of elbows. Where elbows are
required, USE LONG RADIUS ELBOWS ONLY.

Fan Coil
When brazing pipes be sure to use the
insulation blanket shipped with the
merchandiser to prevent damage to the
plastic case bottom.
CAUTION
!

INSULATION
The suction and liquid lines should be clamped or
taped together and insulated for a minimum of
30 ft (9144 mm) from the merchandiser.
Additional insulation for the balance of the liquid
and suction lines is recommended wherever
condensation drippage is objectionable or lines
are exposed to ambient conditions.
SUCTION LINE
• Pitch in direction of flow.
• May be reduced by one size at one third of
case run load and again after the second third.
Do not reduce below the case suction line
size.
• Case suction lines should enter at the top of
the branch line.
LIQUID LINE
• May be reduced by one size after one half the
case run load. Do not reduce below the case
liquid line connection size.
• Take-offs to case liquid lines should exit the
bottom of the branch liquid line. Provide an
expansion loop for each evaporator take-off.

CONTROL SETTINGS
Merchandiser data sheets are shipped with this
manual. The data sheets provide case control
settings and defrost data.
An evaporator pressure regulator or EPR
(primary control) and a 3 – 5ºF (1.7 – 2.7ºC)
differential thermostat (secondary control) must
control refrigeration temperature. The EPR must
be set to maintain the proper saturated evaporator
temperature as listed in the data sheets. The
thermostat must be set a couple degrees colder
than the discharge air temperature specified in the
data sheets. The thermostat will prevent product
freezing should the EPR temperature drift down-
ward during reduced load periods (lights off,
lower ambient). The thermostat will be wired to
control the compressor motor contactor (single
compressor) or a liquid line solenoid valve
(parallel compressor systems).
Defrost is Off Time. Defrost control settings are
listed in the data sheets. When these merchandis-
ers are connected to parallel compressor systems,
a suction stop valve must be used to isolate the
evaporator during defrost periods.
REFRIGERATION THERMOSTAT
The bulb for the optional refrigeration thermostat
is located in the discharge air of the evaporator.
The optional refrigeration thermostat is located
behind the exterior rear panel.
DEFROST TERMINATION THERMOSTAT
The standard disc type defrost termination
thermostat is not adjustable. This thermostat
is clamped to the inlet of the coil on the left-
hand (facing front) end of the merchandiser.

MERCHANDISER ELECTRICAL DATA
Merchandiser data sheets are shipped with this
manual. The data sheets provide case electrical
data, electrical schematics, parts lists and
performance data. Refer to the merchandiser data
sheets and case serial plate for electrical informa-
tion.
ELECTRICAL CONNECTIONS
All wiring must be in compliance with NEC and
local codes. All electrical connections are to be
made in the electrical raceway or Handy Box.
FIELD WIRING
Field wiring must be sized for component
amperes stamped on the serial plate. Actual
ampere draw may be less than specified. Field
wiring from the refrigeration control panel to the
merchandisers is required for defrost termination
thermostats and for optional refrigeration thermo-
stats. When multiple merchandisers are on the
same defrost circuit, the defrost termination
thermostats are wired in series. ALWAYS CHECK
THE SERIAL PLATE FOR COMPONENT AMPERES.
IDENTIFICATION OF WIRING
Leads for all electrical circuits are identified by
colored plastic bands. These bands correspond to
the color code sticker (shown below) located
inside the merchandiser’s raceway.

WASTE OUTLET AND WATER SEAL
The waste outlet is located in front of the fan
plenum 6 ft (1829 mm) from the left-hand of the
merchandiser (facing case front) allowing drip
piping to be run under the fixture lengthwise. A
11/2in. (38 mm) water seal is supplied with each
fixture. The water seal must be installed to
prevent air leakage and insect entrance into the
fixture. A tee, adapter, ell, and plug have been
shipped to allow field installation to determine
direction of drain.
NOTES:
Water seal outlet must clear front skid rail.
PVC–DWV solvent cement is recommended.
Follow the manufacturer’s instructions.
INSTALLING DRIP PIPING
Poorly or improperly installed drip pipes can
seriously interfere with the operation of these
merchandisers, and result in costly maintenance
and product losses. Please follow the recommen-
dations listed below when installing drip pipes to
ensure proper installation.
1. Never use drip piping smaller than the nominal
diameter of the pipe or water seal supplied
with the merchandiser.
2. When connecting drip piping, the water seal
must be used as part of the drip piping to
prevent air leakage or insect entrance. Never
use two water seals in series in any one drip
pipe. Double water seals in series will cause
an air lock and prevent draining.
3. Pitch the drip piping in the direction of flow.
There should be a minimum pitch of 1/8in. per
foot (3 mm per 300 mm).
4. Avoid long runs of drip piping. Long runs
make it impossible to provide the pitch neces-
sary for good drainage.
5. Provide a suitable air break between flood rim
of the floor drain and outlet of drip pipe.
6. Prevent drip pipes from freezing:
A. Do NOT install drip pipes in contact with
uninsulated suction lines. Suction lines should
be insulated with a non-absorbent insulation
material.
B. Where drip pipes are located in dead air
spaces, such as between merchandisers or
between a merchandiser and a store wall, pro-
vide means to prevent freezing.
Note: To prevent condensation problems, the
water seal should be insulated.
