Cleaning Condenser Coils - Hussmann microSC VRL Installation & Operation Manual

CLEANING CONDENSER COILS

The coil should be cleaned at least once each month to maintain peak operating efficiency.
A dirty coil slows product cooling significantly and increases energy consumption by as much
as 20 percent. Dirt buildup on coils can also cause the compressor to lock up damaging the
condenser unit.
To clean the coils, use a vacuum cleaner with a wand attachment and a soft (non-metallic) brush
to remove dirt and debris. Do not bend coil fins. Always wear gloves and protective eye wear
when cleaning near sharp coil fins and dust particles.
NEVER USE SHARP OBJECTS AROUND COILS. Use a soft brush or vacuum brush to clean
debris from coils. Do not puncture coils! Do not bend fins. Contact an authorized service technician if a
coil is punctured, cracked, or otherwise damaged.
All VRL models have the same access panel design for commonality between merchandisers. To
remove the front grille perform the following steps:
1. Lift up, and pull off the grille.
2. Remove the holding bracket to release the condensing unit base. Once the condensing unit
base is free, you can slide it out for service. Use base flange to pull out the condensing unit.
Pulling on refrigeration lines or others parts will cause damage to the unit.
Lift up, and pull off the grille.
