INSTALLATION INSTRUCTIONS
INFINITY/ EVOLUTION CONTROL WIRING
The Steam Humidifier produces internal 24VAC in
order to energize control circuits . For this application,
a 24VAC N .O . Isolation Relay (DPST) part number
HN61KQ120 available through Totaline, MUST be
used to prevent mixing the internal humidifier power
with the indoor equipment transformer . Applying
24VAC isolation relay coil to furnace or fan coil
HUM and COM terminals will allow the Infinity/
Evolution Control to automatically energize the HUM
output during a call for humidification . The N .O . relay
contacts will be used to energize the humidifier . See
Figure 8B for wiring Infinity/Evolution control .
DRAIN LINE
Attach the 7/8" I .D . drain tubing provided to the drain
assembly at the bottom of the humidifier . Secure with
the hose clamp provided . Do not over tighten .
Make sure the drain line has a constant downward
slope from the humidifier to the drain and is not
kinked or blocked .
If floor drain is not available, use condensate pump
(Part #5392) to route water to a suitable drain .
Provide at least 16 inches for of drain line between
the steam humidifier and the condensate pump .
Note: The humidifier uses cold water to temper drain
water to less than 140°F .
