For access to these fans:
1. Remove product and place in a refrigerated area.
Turn off power to the merchandiser.
2. Remove bottom display pans.
3.
Disconnect fan from wiring harness.
4. Remove fan blade.
5. Lift fan plenum and remove screws holding bottom
of motor to fan basket.
6. Replace fan motor and blade.
7. Lower fan plenum.
8. Reconnect fan to wiring harness.
9. Turn on power.
10. Verify that motor is working and blade is turning
in the correct direction.
11. Close air gaps under fan plenum. Warmer air
moving into refrigerated air reduces effective
cooling. If the plenum does not rest against the
case bottom without gaps, apply foam tape to the
bottom of the fan plenum to reduce improper air
movement. Use silicone sealant to close other gaps.
12. Reinstall display pans. Bring merchandiser to operating
temperature before restocking.
