mode will increase the preheated solution
temperature an additional 11
_
C (20
_
F) at the
spray tips.
Example: Preheated solution
temperature of 66
_
C (150
_
F) will increase to a
maximum temperature of approximately 77
_
C
(170
_
F).
ATTENTION: DO NOT switch from PREHEAT to
CLEAN mode when pump switch is activated,
pump and gauge damage may occur (not covered
by warranty). Always turn pump switch off before
turning preheat/clean knob.

NOTE:
In order to get optimum water heat at spray
tips while operating, keep preheat/clean knob in
CLEAN mode. Cleaning in PREHEAT mode will not
harm machine, this will only prevent optimum water
heat at spray tips.
