Note
In cold environments the effectiveness of the cleaning mixture is enhanced if it is heated. Heating can be
accomplished by installing a propane heater underneath the heat exchanger and temporarily enclosing
the unit with a tarp to heat up the cleaning mixture as it circulates cleaner solution through the exchanger.

Note
The length of flushing time and number of fill/drain cycles needed to achieve desired water quality will
vary with system size and the amount of residual (trapped) liquid in the system. Residual liquid is trapped
in the system and cannot be removed when the system is drained. Smaller systems with less residual liquid
may require a lower number of flush cycles.
