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

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.

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.

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

ance of 4 inch es (102 mm ) between the merchan-

EXTERIOR LOADING

Do NOT walk on top of merchandisers or damage to the merchandisers and serious personal injury could occur.

They are noT sTrucTurally designed To supporT

excessive exTernal loading such as the weight of

a person. Do not store items or flammable materials atop the unit.

For California Businesses:

This product may contain chemicals

known to the State of California to

cause cancer, birth defects, or other

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.

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.

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.

Check the following before the rear of the case is positioned at its final location according to the store plan:

1. The external braces must be reinstalled with (6) nuts per brace, torqued to 24 foot pounds.

Do not walk on top of merchandiser.

FINAL LOCATION

Once the case reaches its final location, reassemble the wireway and door handles as follows:

1. Reinstall wireway pan in reverse order of removal.

2. The ground lug must be reinstalled using the screws provided.

3. Replace the conduit connectors and plastic gromets to the wireway pan.

LEVELING

Merchandisers must be installed level to ensure proper

operation of the refrigeration system and to ensure

proper drainage of defrost water. When leveling mer-

chandisers, use a carpenter’s level as shown.

Metal leveling shims or wedges are provided with each

merchandiser for use if needed.

Rear external frames must be

reinstalled securely before setting

or unloading shelves.

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 may be 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 2inch (51mm) partition kit is required. To join same temperature merchandisers on different defrost cycles, a plexiglass partition kit is required.
