7.8 Condensate in duct
1.
Verify humidifi er capacity versus air volume.
2.
See section 6.1 in trouble-shooting section of this manual.
3.
Verify that hi-limit controller is working. Correct if necessary.
4.
Verify evaporation distance to obstructions or elbows. Correct if
necessary.
5.
Verify steam valve is not leaking. Correct if necessary.
6.
Uninsulated duct may be running through an area where ambient
temperature is below internal duct dew point. Insulate duct externally.
7.9 Steam leaks from P-traps.
1.
Check that height of trap exceeds the static pressure of the duct/AHU,
especially if under negative pressure. Correct if necessary.
2.
Check valve sizing to maximum distributor capacity. Resize valve within
distributor capacity.
3.
Check that inlet steam pressure does not exceed the limits of the valve.
The ultimateSAM distributor itself requires no regular maintenance since its
design has no moving parts. It is recommended that the external surfaces
of the distributor should be inspected once a year. If there is evidence of a
steam leak at one of the static seals, contact Carel.

8. MAINTENANCE
For optional equipment, such as valves, actuators, traps, and strainers, follow
the maintenance instructions in the user manuals that are provided with each
of these devices. These accessories should be inspected at least once a year.
For systems in which the inlet pressure to the control valve is greater than
0.7 bar (10 psig), more frequent inspections of the valve may be required. In
addition, steam hoses should be inspected yearly for evidence of cracking or
hardening.
