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

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%.

Placing refrigerated merchandisers in direct sunlight, 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 merchandisers will seriously impair their operation. Do NOT allow air conditioning, electric fans, open doors or windows, etc. to create air currents around the merchandisers.

To prevent sweating on the exterior surfaces of merchandisers, there must be

A MINIMUM

CLEARANCE OF

4 INCHES (102 MM) between the

merchandisers and other fixtures or walls.

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.

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. The carrier will supply necessary forms.

Concealed Loss Or Damage

When loss or damage is not apparent until after equipment is uncrated, a claim for concealed damage is made. Upon discovering damage, make request in writing to carrier for inspection within 15 days and retain all packing. The carrier will supply inspection report and required claim forms.

HEY ARE NOT STRUCTURALLY

DESIGNED TO SUPPORT EXCESSIVE EXTERNAL

such as the weight of a person. Do not

place heavy objects on the merchandiser.

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 and may damage the coil. T

HEREFORE, BE SURE TO REPLACE

THESE BOLTS WITH THE SHORTER BOLTS

PROVIDED

Be careful not to damage the factory-installed end while moving the merchandiser. Make sure that tools are positioned past the end and beneath the merchandiser’s support bar.

SHIPPING BRACES

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

Locate the shipping block in the center of the heat exchanger (see illustration), and remove it before piping the merchandiser. This block was installed to minimize shipping vibration.

REMOVE FRONT PANEL (D

OES NOT APPLY TO RLT)

Before setting case, remove the front panel as follows: remove screws from front panel tabs, then lift the front panel. Refer to the illustration below. Set panel and screws aside to reinstall once all electrical work is complete.

At completion of all electrical work, installation contractor shall re-install the panels using care to ensure all panels are centered and properly fastened.

LEVELING

Merchandisers must be installed level to ensure proper operation of the refrigeration system and to ensure proper drainage of defrost water. When leveling merchandisers, use a carpenter’s level as shown.

Metal leveling shims or wedges are provided with each merchandiser for use if needed.

NOTE: B

EGIN LINEUP LEVELING

FROM THE HIGHEST POINT OF THE

STORE FLOOR

Place shims under the rail and make sure that they are positioned at a base component (crossbar). This transfers the weight directly from the loaded case through to the floor. Placing shims at other locations will cause uneven distribution of weight leading to piping leaks, as well as sagging or wracked doors.

DOOR ADJUSTMENT

After leveling and joining the merchandisers, adjust and level doors according to manufacturer’s instructions shipped with each product. Factory settings are lost due to vibration during shipment.

JOINING

Sectional construction means that two or more merchandisers may be joined in line yielding one long continuous display requiring only one pair of ends. Joining kits and instructions are

shipped with each merchandiser.

To join like fixtures, a joining kit is required. To join unlike fixtures, or like fixtures operating at different temperatures, a 1

2 inch (38 mm)

partition kit is required. To join same temperature fixtures on different defrost cycles, a plexiglass partition kit is required.

INSTALLING BUMPERS

Offsetting the bumpers and top rails helps to disguise the joint locations, giving the lineup a smoother look.

Begin at the left end of the line-up. A starter bumper is factory-installed with end kits. Insert the internal joint trim, then add the full-length bumper.

Align each bumper section with its retainer and push into place, working from the end of the lineup. Install full length bumpers and internal joint trims offset across joints. Make sure that no gaps exist between sections. Continue installing bumpers the length of the line up.

Do NOT install the last bumper sections at this time. These sections will be installed in the last step.

Once all except the last section of bumper have been installed, refrigerate the case line-up for at least six (6) hours. The last sections of bumper should be kept inside a refrigerated case or cooler during this time to allow the bumpers to contract.

Before installing the last full-length section, measure the remaining space. Use a miter box and fine-tooth saw to cut last bumper to length. Install the last section.

REFRIGERANT

The correct type of refrigerant will be stamped on each merchandiser’s serial plate which is located on the left-hand end of the interior top liner.

REFRIGERANT PIPING

Connection Location

The refrigerant line connections are at the righthand end of the merchandiser (as viewed from the front) beneath the display pans.

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 merchandiser to merchandiser through the end frame saddles provided for this purpose. D

O NOT

RUN

REFRIGERANT LINES THROUGH MERCHANDISERS

THAT ARE

NOT ON THE SAME REFRIGERATION

SYSTEM

as this may result in poor refrigeration

control and compressor failure.

NOTE: If Gas defrost is used, the liquid line will need to be increased two sizes larger inside the merchandiser area. This is necessary to ensure even liquid drainage from all evaporators during defrost.

Line Sizing

Refrigerant lines should be sized as shown on the refrigeration legend that is furnished for the store or according to ASHRAE guidelines.

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.

INSULATION

With GAS Defrost

The suction and liquid lines should NOT contact each other and should be insulated separately for a minimum of 30 ft (9144 mm) from the merchandiser.

With OTHER Than Gas Defrost

The suction and liquid lines should be clamped or taped together and insulated for a minimum of 30 ft (9144 mm) from the merchandiser.

With All Defrost

Additional insulation for the balance of the liquid and suction lines is recommended wherever condensation drippage is objectionable or the lines are exposed to ambient conditions.

P/N 0387183_D 2-1

HUSSMANN CORPORATION • BRIDGETON, MO 63044-2483 U.S.A.

REFRIGERATION / ELECTRICAL

When brazing pipes be sure to use the

insulation blanket shipped with the

merchandiser to prevent damage to

the plastic case bottom.

Refrigeration lines are under pressure and should be depressurized before attempting

to make any connections.

EXPANSION VALVE ADJUSTMENT

Expansion valves must be adjusted to fully feed the evaporator. Before attempting to adjust valves, make sure the evaporator is either clear or only lightly covered with frost, and that the merchandiser is within 10 deg F (6.5 deg C) of its expected operating temperature. Adjust valves as follows:

Attach two sensing probes (either thermocouple or thermistor) to the evaporator. Position one under the clamp holding the expansion valve bulb; securely tape the other to the coil inlet line.

Some “hunting

”

of the expansion valve is normal. The valve should be adjusted so that during the hunting

THE GREATEST DIFFERENCE

BETWEEN THE TWO PROBES IS

3–5 deg F (1.7–2.8 deg C).

With this adjustment, during a portion of the hunting the temperature difference between the probes will be less than 3 deg F (1.7 deg C) and at times 0.

Make adjustments of no more than 1/

4 turn for Balanced

Port TEV and

2 turn at a

time for other valve models. Wait at least 15 minutes before rechecking the probe temperature or making further adjustments.

REFRIGERATION THERMOSTAT

The thermostat body is located in the electrical raceway near the right-hand end of the merchandiser. Its sensing bulb is located behind the right end interior back panel.

MERCHANDISER ELECTRICAL DATA

Merchandiser data sheets for specific models are shipped with this manual. The data sheets provide merchandiser electrical data, standard electrical schematics, parts lists and performance data.

Refer to the merchandiser data sheets and case serial plate for electrical information. Refer to the separate wiring diagrams shipped with the case for specific information about the case and any optional wiring kits that may have been applied.

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 thermostats. 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

Electric Defrost is standard for low temperature merchandisers and requires temperature termination. Gas defrost is optional

Off Time Defrost is standard for medium temperature merchandisers and is time terminated.

When two or more merchandisers with full length raceways are installed in line, remove the splashguards, end caps and raceway covers, and install the nipple and nuts (supplied) providing electrical passage from one merchandiser to the next.

Following NEC and local codes is the responsibility of the electrical contractor.

ELECTRICAL CONNECTIONS

All wiring must be in compliance with NEC and local codes. All electrical connections are to be made to the terminal blocks in the electrical raceway behind the lower front panel at the righthand end of the merchandiser (facing front).

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 raceway.

WASTE OUTLET AND WATER SEAL

The waste outlet location varies for each of the 1, 2, 3, 4, and 5 door merchandisers. Drip piping is located between the front case base and the splashguard fixture and runs parallel to the case (see Data Sheet for exact locations).

INSTALLING DRIP PIPING

Poorly or improperly installed drip pipes can seriously interfere with the merchandiser's operation and result in costly maintenance and product losses. Please follow the recommendations 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.

OUBLE 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

/8 inch

per foot (1 mm per 100 mm).

4. Avoid long runs of drip piping. Long runs make it impossible to provide the pitch necessary for good drainage.

5. Provide a suitable air break between flood rim of the floor drain and outlet of drip pipe. To meet code on low base merchandisers, it may be necessary to install a field-supplied drip pipe reducer. An alternative is to cut the last section of drip pipe at an angle.

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, provide means to prevent freezing.

SEALING SPLASHGUARD TO FLOOR

F REQUIRED by local sanitation codes, or if

desired by the customer, plastic splashguards may be sealed to the floor using silicone type sealer. The amount needed will depend on how much the floor is out of level.

• Remove all dirt, wax and grease from the area of the splashguard where adhesion will be necessary. This is to ensure a good and secure installation.

• Apply a good silicone type sealer along the bottom of the splashguard. Sealant must be removed and replaced when servicing.

PTIONAL Stainless steel splashguards may be

sealed to the floor using a vinyl cove base trim. The size of trim needed will depend on how much the floor is out of level.

To install the trim to the splashguard:

• Remove all dirt, wax and grease from the area

of the splashguard where adhesion will be necessary. This is to ensure a good and secure installation.

• Apply a good contact cement to the cove trim

and allow proper drying time according to the directions supplied with the cement.

• Install the trim to the splashguard so that it is

lying flush with the floor. D

O NOT SEAL THE TRIM

TO THE FLOOR

• If required by local health codes Cove Trim

may be sealed to the floor using a silicone type sealer. Sealant must be removed and replaced when servicing.

STARTUP

See the merchandiser's Data Sheet Set for refrigerant settings and defrost requirements. Bring merchandisers down to the operating temperatures listed on the data sheet.

STOCKING

Product should NOT be placed in merchandisers until all refrigeration controls have been adjusted and merchandisers are at proper operating temperature.

All shelves and the lower deck are intended to display product. Shelf height is adjustable in one inch increments. Spacing of 12 inches is recommended for most applications. Maximum load per shelf is 170 pounds. Merchandisers may be ordered with optional “L” shaped wire shelves.

Proper rotation of product during stocking is necessary to prevent product loss. Always bring the oldest product to the front and set the newest to the back.

IR DISCHARGE AND RETURN FLUES MUST REMAIN

OPEN AND FREE OF OBSTRUCTION AT ALL TIMES

to provide proper refrigeration and air curtain performance. Do not allow product, packages, signs, etc. to block these grilles. Do not use nonapproved shelving, baskets, display racks, or any accessory that could hamper air curtain performance.

Do not prop doors open while stocking. And keep the doors closed as much as possible to prevent coil frosting and high merchandiser temperature.

LOAD LIMITS

Shelf life of perishables will be short if load limit is violated. A

T NO TIME SHOULD MERCHANDISERS

BE STOCKED BEYOND THE LOAD LIMITS INDICATED

DO NOT BLOCK HONEYCOMB
