To maintain peak operating efficiency, the coil should be cleaned at least once each month. A dirty coil slows product cooling significantly and increases energy consumption by as much as 20%. Dirt buildup on coils can also cause the compressor to lock up damaging the condenser unit. All MD models have the same access panel design for commonality between merchandisers.

Remove the holding screw to release the condensing unit base.

Once the condensing unit base is free, you can slide it out for service. Use base handle to pull out the condensing unit. Pulling on refrigeration lines or others parts will cause damage to the unit.

Use a soft hand brush attachment on a vacuum to remove accumulated dust and debris.
