humidity. The unit should be located away from doors, air ducts, and fans that could disrupt air flow
and negatively impact performance.
Cabinet Location Guidelines
• Install the unit on a strong and leveled surface.
- If the surface is uneven, the unit may be noisy.

Defrost System
Refrigerator coils are kept below the freezing point (32 degrees Fahrenheit). During compressor downtime,
the evaporator fan continues to circulate air through the evaporator coil. This air circulation raises the coil
temperature above the freezing point, melting any accumulated frost. Run-o water is drained into the evaporator
pan and evaporated. Automatic defrost timers automatically initiate at pre-set intervals and for a
pre-determined duration.
To use the merchandiser more safely and energy eciently, it is strongly recommended that the drainage pipe
behind the unit is connected to a physical drainage line. The drip tray may flood at high humidity circumstance!
If you find the unit is leaking water, please check if the drip tray floods. Please connect with drainage outlet to
avoid flooding.
Safety/Warning
Please pay close attention to the safety notices in this section. Disregarding these notices may lead to
serious injury and/or damage to the unit.

• To minimize shock and fire hazards, be sure not to overload outlet. Please designate one outlet for
your unit.
• Do not use extension cords.
• Do not put your hands under the unit while it is being moved.
• When the unit is not in use for a long time, please unplug the unit from the outlet.
• After unplugging the unit, wait at least 10 minutes before plugging it back in. Failure to do so could
cause damage to the compressor.
UNPLUG CORD
