Nortec SE Series - Manual (Page 39)

Start Up | 36
Warning: Damaged units or improperly installed units must not be operated. Damaged or
improperly installed units may present a danger to persons and property.
Start Up Procedure
1 Examine the humidifier and installation for damage and or improper installation.
2 Open the supply water shut off valve. If the auxiliary drain valve is installed ensure it is
closed.
3 Slowly open boiler steam isolation valve to allow boiler steam into the steam supply line up
to the CV valve.
4 Turn on the main power using the installed disconnect then turn the On/Off switch on the
front of the humidifier to On.
The LCD display will illuminate and the humidifier will perform
a self-diagnostic sequence during which the LED’s and
internal components will be momentarily activated. The SE
will then begin filling with water. The fill time is between 10
and 30 minutes depending on the size of the unit.
5 Once the water level is close to the top of the tank the LED
lights on the SE’s float chamber will light up and indicate the water level. On start up the SE
will perform a float and drain pump test by first filling until just the green LED is lit and then
draining until just the red LED is lit. After the float and drain test the humidifier is in normal
operation mode.
6 If On/Off or a control humidistats have been installed check and adjust the control setpoint
on the control and high limit humidistat (see Nortec Digital Controls on page 39). If
transducer controls have been installed then adjust the humidity setpoint using the keypad
and display (see Transducer Control on page 39)
7 When either the external humidistat or internal controller generate a demand for humidity
higher than 15%, the security loop is closed, and the float chamber indicates the tank is full
the SE will transmit a signal to the CV valve to open. Steam will flow into the SE’s heat
exchanger(s) and the SE will heat the water in its tank.

Note: on initial startup with cold water in the SE’s tank it may take 5 to 15 minutes
(depending on unit size) for the SE to reach a full boil and produce its rated steam.
Note:

Pressing the ESC key on the keypad will interrupt the float and drain test and the
humidifier will go straight to normal operating mode.

If an error is detected during the self-diagnostic sequence a Fault will be displayed.
See troubleshooting section for information on diagnosing and correcting faults.

SEP does not have an LCD display. The information on the SETC’s LCD depends on
the SETC’s configuration and actual operating conditions. It may vary from display
shown.
