Operation

Defrost System

Automatic Defrost Cycle

• Refrigerator coils are kept below the freezing point (32°F).

• 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-off water is drained into the evaporator pan and evaporated.

• Automatic defrost timers initiate at pre-set intervals and for a pre-determined duration.

• If a drainage pipe is available, lower the condensation drainage pipe and connect to a drain or condensate

pump. Verify the pipe is unobstructed and it is lower than water receiver indicated by the line on the sticker.

• If no drain is available, the condensation drainage pipe can be hung up. The excess water will be evaporated

with the condensate evaporator pan. Note that the use of this option will increase the energy consumption of

the unit.

• If your cooler utilizes wicking pads for absorption of condensation, it is recommended that the pads

(22477146) be replaced every 4-6 months depending on the ambient temperature and relative humidity of the

environment.

• If water is leaking from the cabinet, check that the wicking pads have recently been changed and/or the

drainage pipe is connected properly.

• WARNING: High humidity environments can cause increased amounts of condensation that can overflow the

evaporator pan. Connecting the drainage pipe to a nearby drain is necessary for environments exceeding 55%

relative humidity.

Running a Manual Defrost Cycle

• Units are pre-programmed to run automatic defrost cycles at preset intervals. However, if you would like to run

a manual defrost cycle at any time, follow the steps below. Only models with digital controls can run a manual

defrost cycle. Units with mechanical controls cannot run a manual defrost cycle.

• Controller #1: Press the defrost button ("DEF" and ▼) for approximately 5 seconds.

Repeat to stop the defrost cycle.

• Controller #2: Press the defrost button (Snowflake and ▼) for approximately 3 seconds.

Repeat to stop the defrost cycle.

Loading Product

• Ensure there is at least 4" of clearance from the evaporator.

• Ensure all shelves are sitting level and properly secured before loading products.

• DO NOT store flammable/explosive gas or liquids inside the unit.
