How to Repair an Evaporator Distributor

The distributor trough dispenses water to the evaporator pad in a humidifier. Over time, problems can occur with these parts. The evaporator pad will eventually become accumulated with deposits, and this will obstruct the absorption of water. Additionally, leaks can occur if the distributor cover is too loose to contain the water pressure. Uneven water flow from an unbalanced humidifier will also affect how the distributor operates. All three of these problems can be repaired in just three short steps.

Non-sudsing liquid detergent
New evaporator pad (if needed)
Soft, clean cloth
Wrench

Instructions

- 1
  Use a wrench to tighten the distributor trough (the narrow receptacle part of the distributor) to stop water from escaping from high pressure. Make sure the distributor trough cover is tightened as well.
- 2
  Replace the evaporator pad if it becomes corroded with lime deposits. Dirty pads will slow down and stop the water from flowing through the distributor trough.
- 3
  Verify that the distributor trough is completely level on all sides if water does not flow through every hole in the part. Use a liquid detergent that does not produce suds and a clean cloth to clean out the notches on the distributor trough.
