Descale Heating Coil
In hard water areas, scale can build up inside the
heating coil tubing. Scale deposits will decrease the
output pressure and temperature of heated spray and
may eventually clog water flow through the heating coil.
Descale the coil tubing at least annually and more
frequently if you detect a decrease in output pressure or
temperature.
CAUTION: De-scaling burn hazard
Do not run the burner while de-scaling.
To Descale the Coil:
• Wear rubber gloves.
• Mix a commercial coil cleaner in a 5-gallon bucket
and elevate bucket so it is higher than the
unloader.
