As part of an ongoing maintenance program for Innovator Doors, Hussmann recommends that the items below be checked annually.

b) Gasket performance (check for tearing and proper sealing)

c) Check the top hinge pin to ensure the pin is properly seated and not bent

d) Check the bottom hinge plate for excessive wear (worn cam teeth)

e) Proper operation of hold open brackets

1. Check the doors for proper closing torque:

Test 1: Open door 90 degrees and close it manually. Make sure the door opens and closes without binding.

Test 2: Open door 90 degrees and release it. The door should close on its own.

Warning: Always turn off power to the case before working on any electrical components.

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 VRL models have the same access panel design for commonality between merchandisers.

Loosen screws at each side of the front bottom grille, then lift up and pull off the grille.

Detach the merchandiser’s electrical wire harness.

Unscrew the stop bracket that holds the condensing unit to the rail base.

Grab the condensing unit from condensing unit handle. Use only the unit handle to pull out the refrigeration system. Pulling on refrigeration lines or other parts will cause damage to the refrigeration unit.

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

Consult an authorized service technician if more extensive cleaning is needed. If the refrigeration unit is damaged, it can be replaced with a new unit.
