Basic Maintenance — Drain Maintenance

Check for excessive water accumulation inside the unit

Ensure the drain tube is connected from the evaporator housing to the condensate evaporator drain pan

Inspect for water collected underneath the unit

Verify the condensate evaporator drain tube is inside the drain pan

Ensure all drain lines are free of obstructions

Remove any food product blocking the drain lines

Inspect the condenser coil for debris and dust accumulation

Clean the condenser coil with a brush if light dust and debris are present

Use a vacuum or compressed air for heavier dust build-up

Apply de-greasing agent for heavy grease presence and blow through with compressed air

Is a commercially available condenser cleaner required?

Ensure no high pressure water wash is used to avoid damage to electrical components

Operation — To Set Time of Day (Two & Three Door Models Only)

Grasp the knob of the Paragon 8145 time clock dial in the center of the inner (2 hour) dial and rotate it in a counter-clockwise direction.

Continue turning until the correct time of day on the outer dial lines up with the time pointer.

Was the correct time set on the outer dial?

Was there an interruption of power to the freezer?

Disconnect power supply before servicing.

Ensure no live electrical parts are exposed.

Select the cleaning method based on the coil condition

Is the condenser coil free of dust, dirt, and grease after cleaning?

Ensure no high pressure water is used during cleaning

Clean the condenser fins with a vacuum cleaner or stiff brush

Was a commercially available condenser cleaner used?

Are the condenser fins visibly clean and undamaged?

Is the refrigeration performance normal after cleaning?
