(TSEW Models) Check the condition of the
condenser water for algae, scale, and particulate
fouling. Rod out the tubes and back flush the
condensers. If scaling exists on the condenser
tubes, chemical cleaning of the tubes may also
be necessary. If a chemical cleaning agent is
used, it should be suitable with the internal
components composed of copper, steel, and
cast iron. The frequency at which this task is
required depends on specific site conditions.
21.
(TSER Models) Check the condition of the air
coils of the remote condensers for dirt and
debris. If the coils are dirty or clogged, use a
compressed air source to blow the contaminants
out of the air coil. The frequency at which this
task is required depends on specific site
conditions.

Have a qualified laboratory perform a
compressor oil analysis to determine system
moisture content and acid level.
Cleaning the Operator Interface
Use of abrasive cleaners or solvents may damage the
window. Do not scrub or use brushes. To clean the
display window:
1.
Disconnect power from the terminal at the
power source.
2.
Using a clean sponge or a soft cloth, clean the

by rubbing lightly with isopropyl alcohol.
Afterward, provide a final wash using a mild
