Hussmann Merchandiser E1S

• Honeycombs should be cleaned every six months. Dirty honeycombs will cause merchandisers to perform poorly. The honeycombs may be cleaned with a vacuum cleaner. Soap and water may be used if all water is removed from the honeycomb cells before replacing. Be careful not to damage the honeycombs.

1. Using a flat object such as a screw driver, compress the honeycomb and remove it from its retainer.

2. Clean and dry the honeycomb.

3. After cleaning, replace in reverse order.

• The interior back panels may be removed for cleaning and to gain access to the evaporator coils. Remove the rear interior back panels as follows:

1. Disconnect the electrical power to the merchandiser.

3. Remove the lower panel first: lift the panel up, then pull forward and out.

• Fluorescent lamps are furnished with moisture resistant lamp holders, shields and end caps.

• Whenever a fluorescent lamp is replaced, be certain to reinstall the lamp shields and end caps.

• The switch in the canopy operates both the canopy and the shelf lamps. The rail lamp switch is located on the rail.

• Inspect all lamp sockets and plug–receptacle connections for signs of arcing. Replace any component that shows signs of arcing.

• Make sure all unused receptacles have their close-off covers securely attached.

2. REPLACING LAMP HOLDERS AND END CAPS

• The Impact lamp holder is designed to snap into the sheet metal of the case. The lamp holder has a locking ‘nub’ which fits inside the groove of specially designed end caps.

CAUTION! Fluorescent lamps contain mercury vapor. Mercury exposure at high levels can harm the brain, heart, kidneys, lungs, and immune system of people of all ages. Do not break or puncture fluorescent lamps. Dispose of, or store, all fluorescent lamps in accordance with Federal (40 CFR 273), State, and local hazardous waste requirements.

* NEVER USE SHARP OBJECTS AROUND COILS. Use a soft brush or vacuum brush to clean debris from coils. Do not puncture coils!

• Do not bend fins. Contact an authorized service technician if a coil is punctured, cracked, or otherwise damaged.

• ICE in or on the coil indicates the refrigeration and defrost cycle is not operating properly.

• Contact an authorized service technician to determine the cause of icing and to make adjustments as necesssary. To maintain product integrity, move all product to a cooler until the unit has returned to normal operating temperatures.

• Clean bumpers with household spray cleaner.

• To remove marks from a ballpoint pen, use hair spray or dry erase cleaner.
