# §429.36. Dehumidifiers.

- (a) **Sampling plan for selection of units for testing.**
  - (1) The requirements of [§ 429.11](/cfr/10/429.11.md) are applicable to dehumidifiers; and
  - (2) For each basic model of dehumidifier selected for testing, a sample of sufficient size shall be randomly selected and tested to ensure that—
    - (i) Any represented value of energy consumption or other measure of energy consumption of a basic model for which consumers would favor lower values shall be greater than or equal to the higher of:
      - (A) **The mean of the sample, where—**
      - (B) The upper 95 percent confidence limit (UCL) of the true mean divided by 1.10, where:
    - (ii) Any represented value of the energy factor, integrated energy factor, or other measure of energy consumption of a basic model for which consumers would favor higher values shall be less than or equal to the lower of:
      - (A) **The mean of the sample, where—**
      - (B) The lower 95 percent confidence limit (LCL) of the true mean divided by 0.90, where:
  - (3) The capacity of a basic model is the mean of the measured capacities for each tested unit of the basic model. Round the mean capacity value to two decimal places.
  - (4) For whole-home dehumidifiers, the case volume of a basic model is the mean of the measured case volumes for each tested unit of the basic model. Round the mean case volume value to one decimal place.
  - (5) **Round the value of energy factor or integrated energy factor for a basic model to two decimal places.**
  - (6) Dehumidifiers distributed in commerce by the manufacturer with the ability to operate as both a portable and whole-home dehumidifier by means of installation or removal of an optional ducting kit, must be rated and certified under both configurations.
- (b) **Certification reports.**
  - (1) The requirements of [§ 429.12](/cfr/10/429.12.md) are applicable to dehumidifiers; and
  - (2) Pursuant to [§ 429.12(b)(13)](/cfr/10/429.12.md?p=b-13), a certification report must include the following public product-specific information:
    - (i) **For dehumidifiers tested in accordance with appendix X—** The energy factor in liters per kilowatt hour (liters/kWh) and capacity in pints per day.
    - (ii) **For dehumidifiers tested in accordance with appendix X1—** The integrated energy factor in liters per kilowatt (liters/kWh), capacity in pints per day, and for whole-home dehumidifiers, case volume in cubic feet.
