NOTE
In an extreme case where the heat exchanger cleaning has been neglected
Flush as directed in the diagram using a pressure washer
without chemical additives and for
maximum 10 minutes to avoid complete saturation of the gaskets.
o
After flushing shake excess water from the heat exchanger and replace directly
o
Assemble in reverse order of removal
o
Do not use tools to tighten the thumb screws, if available lubricate threads with grease
(even olive oil can be used) This will make the thumb screws easier to turn by hand.
o
Once assembled switch the Fresh-r on and close the door
