Steam Distributors
Symptom
Cause
Corrective Action(s)
Distributor spitting out water
1 Distributor not level
1 Use support at end o 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 insure 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.
SAM-e
Symptom
Cause
Corrective Action(s)
SAM-e spitting out water
1 “P” Trap too close to SAM-e
1 “P” trap must be at least 12 in (30
cm) below header. Relocate if
required.
2 Condensate line not sloped
sufficiently
2 Ensure line is sloped sufficiently to
carry condensate produced.
3 Steam line not insulated
3 If steam line is long condensate build
up could overload the SAM-e
condensate port. Insulate the steam
line to improve efficiency and install
condensate traps as required.
