Nortec SETC Outdoor - Manual (Page 13)

Installation | 10
 Seal building after plumbing to ensure that building pressure remains as intended.
 Avoid installing the humidifier in an area where building exhaust may enter the cabinet
through ventilation louvers. A minimum clearance of 10ft (3m) from mechanical exhaust
outlets is recommended.
 Install so that ventilation louvers are not obstructed and cannot be blocked by accumulation
of ice and snow.
SETC Outdoor Curb
The base of the SETC includes a drain pan with a pipe chase to route water, drain, boiler steam,
boiler steam condensate, control wiring, and primary power wiring. The roof curb should be
designed to support the base and allow services to be routed to the humidifier through the pipe
chase.

Note:
 Cut-outs in the base of the unit are designed to allow lifting with a forklift.
 Four removable lugs on the base are provided to allow the humidifier to be craned
into position. Protect the cabinet from cable/strap/chain damage while lifting.
Caution: When installing the SETC Outdoor in conditions where freezing temperatures
may occur ensure that freeze protection guidelines are followed. See Freeze Protecting
