PRINCIPlE OF OPERATION

The purpose of the Aprilaire ® Dehumidifier is to keep humidity in a space at acceptable limits, reducing
the unwanted effects of high humidity. The dehumidifier measures the condition of the air in the space
to determine when to run.
Do not use a dehumidifier to prevent window condensation in the winter. Indoor humidity levels must
typically get lower than what dehumidifiers can achieve during cold winter months. Use ventilation to
lower indoor humidity levels in the winter.

and cement to secure the trap in
place. Cement the supplied threaded
90-1393
coupler to the outlet of the trap.
• S crew the supplied hose barb fitting into the coupler and attach the supplied
Route the hose to the nearest drain.
