8.2 DefRoST ConDiTionS
8.3 Coil SenSoR oPeRaTinG PRoPeRlY:
While the
compressor is running in the AUTO DEHUMIDIFY MODE, the
control unit will monitor the coil sensor and measure how much
time it sees a coil temperature that is equal to or less than 30
˚F (-1 °C). Once that count reaches 15-minutes, the unit will
perform a DEFROST CYCLE.
8.4 Coil SenSoR MalfUnCTioninG (DiGiTal DiSPlaY
SHoWS “e1”):
The unit will perform DEFROST CYCLES after the
compressor has run for 53 minutes.
8.5 DefRoST CYCle:
During a DEFROST CYCLE, the compressor
will turn off, the fan motor will turn on, the RED DEFROST LED will
illuminate and the 15 minute defrost timer will be reset.
8.6 DefRoST CYCle CoMPleTe ConDiTionS
8.6a Coil SenSoR oPeRaTinG PRoPeRlY:
When the coil
sensor sees a temperature higher than 37 ˚F (3 °C) for 4 minutes,
the control unit will exit the DEFROST MODE.
8.6B Coil SenSoR MalfUnCTioninG (DiGiTal DiSPlaY
SHoWS “e1”):
The control unit will execute a DEFROST CYCLE
for 6 minutes and then exit the DEFROST MODE.
8.6C The DefRoST CYCle leD
will be extinguished.
8.7 DeHUMiDifY CYCle DelaYeD STaRT
(COMPRESSOR
PROTECTION FUNCTION)
When the compressor stops running for any reason (%RH set point
reached, mode change, power off, power failure, etc.), it will not
restart for 3 minutes. When it starts, it will run for a minimum of 5
minutes regardless of the %RH setting.

CAUTION!
eleCTRiC SHoCK HazaRD: Maintenance and repairs should be
performed by a qualified service person.
8.8a Coil SenSoR:
When the coil sensor reports a temperature
that is lower than 4 ˚F (-20 °C) or higher than 158 ˚F (70 °C), the
control unit considers it faulty and will display “E1” in the digital
display. The unit will continue to run in the AUTO DEHUMIDIFY
MODE and will perform a DEFROST CYCLE every 53 minutes of
operation.
8.8B HUMiDiTY SenSoR:
When the humidity sensor’s output
voltage is less than 0.5V or more than 4V, the control unit
considers it faulty and will display “E2” in the digital display. The
unit will run continuously in the AUTO DEHUMIDIFY MODE or FAN
MODE and will perform a DEFROST CYCLE as required.

In the RUN mode, pressing the UP/DOWN buttons
together for 2 seconds will lock the control. None of the buttons
will function except ON/OFF. A decimal point will appear
indicating this condition. Pressing the UP/DOWN arrow buttons
together for 2 seconds again will unlock the control and restore
the all button functions.
9.2 DiSPlaY Coil TeMPeRaTURe:
In the RUN mode, pressing the UP arrow button and the MODE
button together for 2 seconds will display the coil temperature.
Pressing the UP arrow button and the MODE button together for
2 seconds again will return the display to the current %RH of the
room.

11. Maintenance
11.1 air filter
The SaniDry XP is equipped with two (2) air filters. An aluminum/
foam pre-filter followed by a standard MERV-11 65% efficient
pleated fabric filter. These should be checked every six months.
Operating the unit with dirty filters will reduce dehumidifier
capacity and efficiency and may cause the compressor to cycle off
and on unnecessarily.
If dirty, the aluminum/foam prefilter can be vacuumed or carefully
hand washed with warm water and mild detergent then rinsed.
The pleated fabric filter can generally be vacuumed clean several
times before needing replacement. Replacement filters can be
ordered from your local Basement Systems dealer.
Do noT
operate the unit without the filters or with a less effective filter.
The heat exchange coils inside the unit could become clogged and
require disassembly to clean.
