Condenser in and out piping is factory equipped with a 3/4-
inch internal NPT. Remove the plug that comes from the
factory and install fittings as shown in this typical setup. It is
recommended to install supply and return water valves.

the calculation tool allows you to adjust the
amount of ScaleBreak-MP needed based on
the thickness of scale in your SWEP BPHE.

1. Isolate the heat exchanger from the system by closing
the supply and return water valves.
2. Position a ball valve on the low point of the heat
exchanger. This valve will function as the entry point for
your ScaleBreak-MP cleaning and can be closed to
prevent backflow if needed.
3. Attach your circulation hoses so you are pumping into
the bottom of the heat exchanger and returning the fluid
out the top.
4. Your exit point on top needs to be at the highest point of
the exchanger. If the exit point is lower than the top of
the plate pack, position the hose at a higher point. This
action will insure the entire plate pack is flooded and
ScaleBreak-MP comes in contact with all the interior
wetted surfaces. It will also insure upper interior areas
do not become air bound with CO
from the cleaning.
5. Fill your exchanger with water and perform a
hydrostatic test by turning your pump on and circulating
the water. This action assures the exchanger is isolated
and none of the ScaleBreak-MP will be needlessly lost.
6. You will need to bleed off enough water equal to the
volume of ScaleBreak-MP required for the cleaning. If
you relieve too much water, you can add some back to
complete your circulation loop.
7. Water formed deposits will occupy volume, as a result,
additional water may need to be added during the
cleaning process as deposits are dissolved.
8. Periodically check your isolation valves as they may
have initially seated against scale. As ScaleBreak-MP
dissolves the scale, this action will help you avoid
losing product.
9. Circulate the ScaleBreak-MP solution for the
recommended timeframe as indicated by our
calculation tool.
10. During your ScaleBreak-MP cleaning you will want to
make sure your solution remains active. For this step,
please follow our "Testing ScaleBreak's Effectiveness"
procedure.
11. Once you have reached the recommended circulation
time and your ScaleBreak-MP solution has completed
the job, you can begin your flushing process.
