Nortec NH-EL Series - Manual (Page 76)

73 | Troubleshooting
Symptom Cause Corrective Action(s)
5 Capacity has been manually
limited
5 Check Manual Capacity on status
screens. Adjust “Manual Capacity (A/B)”
under “0335” / ”Configuration” /
”Features” / if necessary.
6 Low conductivity water 6 Check if “Max Level”: “Max Level” is
displayed on the humidifier’s display. If
operated on low conductivity water it may
take several hours for the NH-EL 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.
Humidifier has faulted or
has a warning 1 Software has detected an
abnormal condition
1 Refer to Table 11: Troubleshooting
Warnings and Faults.
Steam Distributors
Symptom Cause Corrective Action(s)
Distributor spitting out water 1 Distributor not level 1 Use support at end of distributor to
ensure it is level.
2 “P” Trap too close to distributor 2 “P” Trap must be a minimum of 12 in
(30 cm) below the distributor to
ensure flow. Relocate if required.
3 Condensate line not sloped
sufficiently
3 Sufficient slope to ensure flow is
required. Reinstall if required.
4 Trap blocked 4 Check that water flows through trap.
Clear out if blocked.
5 Condensate line double trapped 5 Condensate lines must not have two
traps in sequence. This can cause an
air lock and prevent water draining.
6 Steam line not insulated 6 If steam line is long, condensate build
up could overload distributor
condensate port. Insulate line to
improve efficiency and install
additional condensate traps as
required.
Condensation in duct 1 Installation clearances not
observed
1 Refer to distributor installation manual
for required clearances. Relocate
distributor if required.
2 Design conditions changed 2 Check supply air temperature and
humidity to determine if conditions
have changed.
3 High limit not functioning 3 Check setting and operation of high
limit. Replace if defective.
4 Air proving not installed or not
working
4 Check that the humidifier will only
operate when there is air moving in
the duct.
5 Improper location of high limit 5 Check that high limit is installed where
it can detect high duct humidity.
