Startup/Operation
The RM-BP is designed to distribute atmospheric steam directly into a space. The RM-BP may be
used in conjunction with the NH-EL Humidifier, as well as other Nortec Humidifiers, including the
Resistive, Gas and Steam Exchange models. The RM-BP is equipped with a 5 foot (1.5m) long
power cable which can be plugged into conventional wall circuits (15 amp single phase). A single
RM-BP can hold a capacity of 100 lbs/hr of atmospheric steam.
The NH-EL Space humidifier is already equipped from factory with a built on blower pack and can
be used for direct room applications.
Sequence of Operation
Once hot steam is generated and reaches the blower pack, a control thermostat located inside the
blowerpack starts the blower fan and allows for steam distribution. The blower pack is equipped
with a security loop which should be wired with the respective humidifier safety. The purpose of the
security loop is to prevent humidifier operation should power be interrupted to the blower pack.
The blower pack is equipped with a dual speed fan switch. The switch can be used to increase or
decrease the fan speed effectively changing absorption distance and noise. Once desired speed is
selected, no further change is required.
