9-4 Maintaining the Evaporator
Dirty heat exchange surfaces on the evaporator reduce system
capacity and efficiency. Remove dirt and slime in the evaporator
by reverse circulating with a mild detergent and water solution.
Remove mineral deposits by reverse-circulating AEC Liquid Citric
Acid De-Scaling Solution (AEC Part No. A0536607). Follow the
directions on the container.
9-5 Evaporator Process Piping Y-Strainer (Optional)
The process piping Y-strainer requires periodic cleaning of its
screen to ensure the proper flow through the evaporator. To clean
the strainer screen, remove the access plug and retaining cap, and
pull out the screen.
Wipe, brush, or vacuum out any and all dirt left behind in the
strainer body. Clean the screen and replace it in the strainer taking
care to fit it squarely into the machined seat provided.
!
CAUTION
Do not forget to re-install the screen after cleaning it.
Operating the chiller with no strainer screen
can potentially plug the evaporator with dirt.
The AEC, Inc. warranty does not cover chiller failures from a dirty evaporator!
