B. PRIMARY VOLTAGE CONNECTION
(1) All blower packs have high efficiency blowers to minimize the frontal and overhead
clearances required to absorb the steam.
(2) NH series remote mounted blower packs require field wiring between 2 primary
voltage terminal blocks and 2 low voltage control terminal strips; one of each is
located in the humidifier and the remote mounted blower pack cabinet. To properly
access the primary block on the humidifier, it may be necessary to remove the right
side panel. To connect the primary wiring and control wiring feed the wire though the
knockouts on the bottom and top of the humidifier. To access the blower pack
terminal strip you must remove the cover. The primary voltage can come from a
remote source as well.
NOTES
Terminal block are pre-installed on units order with a remote mounted blower pack.
Otherwise the terminal block will be provided.
Class 1 circuit wiring is require between humidifier and blower pack.
(4) Field wiring of remote mounted blower pack must conform to national and local
electrical codes.
(5) For NH series use approved wire for power connections from 2 pole terminal block of
the remote mounted blower pack to additional 2 pole terminal block inside the
electrical section of the humidifier.
(6) For NH Series use approved wire to connect ground clamp of remote mounted
blower pack to ground clamp provided in the electrical section of the humidifier.
