How to Check / Clean the Heat Exchange Coil:
(NOTE: See the Operators Safety Manual
The heat exchange coil should be inspected for deposit build-up after 40 hours of use, or once a month, whichever
comes first. In hard water areas a water softening system should be employed.
Scaling or liming of the coils is caused by mineral deposits from the water and occurs much faster in hard- water
areas and with heavier machine usage. Lime build-up can also be caused by inferior cleaning compounds.
DANGER: Failure to properly maintain the heat exchange coil can result in a steam explosion! Scale or lime build-
up will act as an insulation and decrease the efficiency of the heatexchanger coil and will also cause
"hot spots". This can result in a weakening of the tubing which can lead to a steam explosion.
