BEFORE SERVICING

ALWAYS DISCONNECT ELECTRICAL POWER AT THE MAIN DISCONNECT WHEN SERVICING OR REPLACING ANY ELECTRICAL COMPONENT.

This includes (but not limited to) Fans, Heaters Thermostats, and Lights.

Evaporator Fans

The evaporator fans are located at the center front of these merchandisers directly beneath the display pans. Should fans or blades need servicing, always replace fan blades with the raised embossed side of the blade TOWARD THE MOTOR.

Coils

The copper coils used in Hussmann merchandisers may be repaired in the field. Materials are available from local refrigeration wholesalers.

Hussmann recommends using #15 Sil-Fos for repairs.

Tips and Troubleshooting

Before calling for service, check the following:

1.Check electrical power supply to the equipment for connection.

2.Check fixture loading. Overstocking case will affect its proper operation.

3.If frost is collecting on fixture and/or product, check that Humidity Control is working properly, and that no outside doors or windows are open - allowing moisture to enter store.

Replacing Fluorescent Lamps

Fluorescent lamps are furnished with a shatterproof protective coating. The same type of lamp with protective coating must be used if replaced.

CLEANING PRECAUTIONS

When cleaning:

Do not use high pressure water hoses

Do not introduce water faster than waste outlet can drain

NEVER USE A CLEANING OR SANITIZING SOLUTION THAT HAS AN OIL BASE (these will dissolve the butyl sealants) or an AMMONIA BASE (this will corrode the copper componets of the case)

TO PRESERVE THE ATTRACTIVE FINISH:

DO USE WATER AND A MILD DETERGENT FOR THE EXTERIOR ONLY

DO NOT USE ABRASIVES OR STEEL WOOL PADS AS THESE

WILL MAR THE FINISH
