11. The damper stop prevents unwanted air infiltration through either fan. The Damper stop can be adjusted so the damper does not

swing open into the house by wind or a negative pressure in the house. IMPORTANT: The damper stop prevents the damper from

swinging inward and should not be used if using the XCHANGER fan to bring outside air in. With the damper stop pushed all the

way forward, the damper will swing both ways. With the damper stop pulled all the way back, the damper will only swing to the

outside. Use the damper stop only if you want to block air infiltration into the house during seasons when the XCHANGER is not

being used or when using the XCHANGER to exhaust air. .

12. WARNING: Unplug fans from dehumidistat control when changing direction to prevent damage or injury. Insert fans in desired

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

installed confirm the air is being exhausted or supplied depending upon application, (See Diagram O).

13. Insulate around XCHANGER housing, (See Diagram P). IMPORTANT: Use of expanding foam on top of XCHANGER case may

interfere with damper slides on top of XCHANGER case. Make sure damper slides move freely.

XCHANGER DEHUMIDISTAT CONTROL MODULE INSTALLTION & OPERATION

Install XCHANGER dehumidistat control module on wall with provided screws and

wall anchors and plug in XCHANGER fans into side outlets.

IMPORTANT: Do not plug other devices into dehumidistat control or damage may result.

Once fans are installed in XCHANGER, plug in dehumidistat control into standard outlet.

The XCHANGER control module includes an adjustable dehumidistat control which acti-

vates the fan(s) if the relative humidity rises above the selected set-point. The dehumidis-

tat 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 XCHANGER fan(s) to run. Each XCHANGER fan is independently controlled by

its own on/off switch. To inhibit mold growth it is recommended that the Relative Humidity

(RH) be below 60%. Turn switch(s) off during seasons or applications where it is not desired to run that fan, (See Diagram Q).
