PREVENTIVE MAINTENANCE:
1.)
Periodically inspect and clean water inlet screen located at the inlet of the unit (at
the hose attachment on the Ultra 600/1300 models-Ultra 250 filter is part of the
pump).
2.)
Periodically inspect nozzle to make sure it is clean. Restricted water flow, shut
down or interrupted spray pattern is an indication of obstruction in the nozzle.
3.)
DESCALING: hardness or mineral content in water along with steam temperatures
will eventually create a coating or build-up of scale in the heating coils. Excessive
scale will shorten coil life and interfere with temperature controls. Scale appears
periodically. Check for scale build-up on inside of steam connections. When scale
has built-up to such a degree that the machine senses accurate low water flow
internally, the unit will not light, or will light and shut-off. A test for scale build-up
is to remove the nozzle and see if the machine lights, and if it does, then you may
need to descale the unit. Other low water issues maybe the cause, such as a bad
pump, etc. See DESCALING Section.
