11. The X CHANGE R TM comes with (2) air infiltration magnetic draft stops to block incoming air during seasons or periods when the
X CHANGE R TM is not in use if desired. Place magnet(s) over X CHANGE R TM fan opening(s) when fan is not in use to block air infiltra-
tion. Place magnet(s) on side of X CHANGE R TM cabinet so they are not lost if not in use to block fan openings, (See Diagram N).

direction for either exhaust or intake. See arrow on bottom of fan cartridge or side of fan shroud for air flow direction. Once

XCHANGER DEHUMIDISTAT CONTROL MODULE INSTALLATION & OPERATION
XCHANGER DEHUMIDISTAT CONTROL MODULE INSTALLATION & OPERATION
Install X CHANGE R TM dehumidistat control module on wall with provided screws and
wall anchors and plug X CHANGE R TM fans into side outlets.
IMPORTANT: Do not plug other devices into dehumidistat control or damage may result.
Once fans are installed in X
CHANGE R TM , plug dehumidistat control into standard outlet.
The X CHANGE R TM control module includes an adjustable dehumidistat control which
activates the fan(s) if the relative humidity rises above the selected set-point. It is gener-
ally recommended to maintain a Relative Humidity (RH) below 60% to inhibit mold
growth. The dehumidistat can be turned fully clockwise to the ‘on’ position for constant
fan(s) operation or it can be turned fully counter-clockwise to ‘off’ during seasons or
times when it is not desired for the X
CHANGE R TM fan(s) to run. Each X CHANGE R TM fan
is independently controlled by its own on/off switch. Turn switch(s) off during seasons
or applications where it is not desired to run that fan, (See Diagram Q).
