Maintenance

ELECTRICAL PRECAUTIONS

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.

REPLACING FLUORESCENT LAMPS
Fluorescent lamps are furnished with a shatterproof pro-
tective coating. The same type of lamp with protective
coating must be used if replaced.

This lamp has been treated to resist breakage and must be
replaced with a similarly treated lamp in order to maintain
compliance with NSF Standards. NSF CODE 4.28.1

Contact HUSSMANN Chino for replacement

1-800-395-9229 x 2131

T-5 BULBS

Please note: T-5 lights must be turned off and on

after

bulb

replacement.

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.

COPPER 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 & 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.

FOR PROMPT SERVICE

When contacting the factory,

be sure to have the Case Model and Serial

Number handy. This information is on a plate

located on the case itself.
