SEP Humidifier Configuration
The SEP is factory configured to operate under most conditions without the need for any
changes to its configuration. If required several settings can be made using jumpers on the
SEP’s control board. The blowdown of the SEP can also be adjusted by using a potentiometer
on the SEP’s control board. See Figure 46: SEP Control Board Jumpers for location of jumpers
and the blowdown adjustment potentiometer.
Note: Nortec recommends not making any configuration changes unless they are required and
that any changes to the SEP’s settings be performed by a qualified technician.
Figure 46: SEP Control Board Jumpers
Blowdown Adjustment
Sets the amount of water as a percentage of steam produced that
will be drained to control mineral concentration in the tank. The
blowdown adjustment potentiometer is located on the side of the
control board as shown in Figure 46. It can adjust the blowdown
between 0% and 50% of steam produced. (Factory setting = 25%
blowdown).
Note: 0% blowdown should never be used even with Deionized
water. Minimum recommended setting is 5%.
Caution: Never adjust jumpers other than those listed in this section. Other jumpers are
factory set and must not be changed.
