Start Up Procedure
1.
Examine the humidifier and installation for damage
and/or improper installation.
2.
Ensure the cylinder is properly seated in the drain valve
and that the electrode plugs are pushed all the way
down on the cylinder pins.
3.
Ensure that the front cover is in place and secured with
its retaining screws.
4.
Open the supply water shut off valve.
5.
Turn on the main power using the installed disconnect.
WARNING
Personal Injury Hazard.
Damaged or improperly installed units must not be
operated. Damaged or improperly installed units may
present a danger to persons and property.
6. Turn the On/Off switch on the front of the humidifier to
On.
• The humidifier will perform a self-diagnostic
sequence during which the LED’s and internal
components will be momentarily activated. See
“LED Status Lights” on page 14 for an explanation
of the LEDs and sequences.
• If an error is detected during the self-diagnostic
sequence the humidifier will not start. The yellow
status LED will flash in sequence to indicate the
detected fault. See Tables 7 and 8 for information
on diagnosing and correcting faults.
• After the system test the humidifier is in normal
operation mode.
7.
Check and adjust the control setpoint on the control and
high limit humidistat.
8.
When the external humidistat generates a demand for
humidity and the security loop is closed the green
humidifying LED on the front of the humidifier will light
up, the power relay on the control board will engage, the
fill valve will activate (after a delay) and the cylinder will
slowly fill with water.
NOTE: While the cylinder is filling with water there
should be no water flowing down the drain. If
water is flowing down the drain it can indicate
excessive backpressure or a leaking drain valve.
See Troubleshooting.
9.
If a fan enable relay is used, the green LED will continue
to flash until the air proving closes. Once the air closes,
the flashing green LED will become solid and the
humidifier will start steam production as described in
step 8.
10.
It can take 5 – 10 minutes for the water to be heated up
by the submerged electrodes and for steam to be pro-
duced.
NOTE: If operated on low conductivity water it may take
several hours for the HM700 to reach full output
capacity. This is normal. During this time the
humidifier will not perform any drains and the
conductivity of the water in the cylinder will
increase. To expedite this process, add a
1/4 teaspoon of salt to the cylinder. This will
immediately increase water conductivity and
initiate heating.
