Condensate Sample. A condensate sample is collected from the area
where the tester was installed and returned to the supplier at the same time as the
Return of Tester. The tester is packed in any convenient package,
enclosing the completed data sheet, and returned to the supplier.
INSTALLATION OF TESTER
Location of Tester. Install the tester in a horizontal return line. If
morpholine treatment is being used, install the tester in a building near the end of the
steam main where the treatment would be expected to be least effective. If a mixture of
morpholine and cyclohexylamine is used, install a tester at each end of the system.
Test Conditions. Ensure representative sampling of the condensate by
the tester. Do not install the tester to receive drips from steam mains. Drips may be less
corrosive (less acidic) than the average condensate.
Placement of Tester. Place the tester horizontally to receive the
condensate from a hot water generator or space heater that is drained by a 19-
millimeter trap. Do not install the tester downstream from a pump in the condensate line.
Avoid bypasses and do not overload the tester with condensate from several traps.
Enough condensate should flow to the tester to fill it at least halfway.
Method of Installation. To install the tester, remove a section of the pipe
from the condensate return system. Replace the section of pipe with the tester, unions,
and any additional pipe needed to complete the installation.
Length of Test. Leave the tester in place for about 90 days. Record the
dates the tester was installed and removed.
