Table 7. Ceiling and Frontal Clearances for Blower Packs
B.
PRIMARY VOLTAGE CONNECTION
(1) As a safety feature, blower packs come equipped with a manual reset safety
thermostat and relay built into the blower pack cabinet. The manual reset thermostat
locks out the humidifier if the blower pack is not powered. The control thermostat,
mounted on the steam distributor, starts the fans when steam is generated.
(2) All blower packs have high efficiency blowers to minimize the frontal and overhead
clearance required to absorb the steam.
(3) NH Series remote mounted blower packs require field wiring between two primary
voltage terminal blocks and two low voltage control terminal strips; one of each located
in humidifier and remote blower pack cabinet. To properly access the primary block on
the humidifier, it may be necessary to remove the side. To connect the primary and
control wiring, the wiring is fed through the knockouts provided in the bottom of the
blower pack and the top of the humidifier. The terminal block and strip are accessed by
removing the blower pack cover.
NOTE
Class 1 circuit wiring is required between humidifier and blower pack.
(4) Field wiring of remote blower packs must conform to national and local electrical codes.
Refer to wiring diagram supplied at the back of this manual.
(5) For NH Series use approved wire for power connection from two-pole terminal block of
remote blower pack to additional two-pole terminal block inside electrical section of
humidifier.
(6) For NH Series use approved wire to connect from ground clamp of remote mounted
blower pack to ground clamp provided in the electrical section of humidifier.

NOTES: 1. Four remote mounted blower packs are recommended on the 200 model.
2. Clearances based on 72°F at 35% RH.
3. Remote mounted blower pack must be used for 150 and 200 models.
4. When there are clearance restrictions, adding blower packs can resolve the problem. For example, if you
have a series 100 and less than the required minimum clearance, changing from one blower pack to two
50 series blower packs reduces the minimum clearance to 36/84 in. from 48/156 in.
