Apply power to DR90. Turn the humidity control to a low RH% level to initiate a dehumidification call.
Confirm that the DR90 compressor and fan turn on. The furnace blower will also turn on to circulate air. This
will take up to two minutes. Be sure to turn the control to the desired RH% or to Off when checkout is com-
plete.

Cleaning

On an annual basis, maintenance is required to ensure DR90 runs at peak efficiency.
Unplug DR90 before beginning service.

Remove the magnetic filter door.
Remove the panels on each side of the

dust and debris from blower, refrigerant
coils, and compressor coils. Reattach
cabinet panels when finished.

Remove filter (50049536-003) and

replace with new filter.
Check the drain connection and drain
line to ensure it is clear of debris and

sludge. Ensure all hose connections
are secure once maintenance of the
drain lines is complete.
When service is complete, initiate
a call for dehumidification and

check that the compressor and fan
activate. If using the VisionPRO IAQ or
TrueIAQ controls, reset maintenance
reminders.
