Daily
Check the main turbine filter daily for cleanliness.
The turbine systems are lifetime lubricated. The only
maintenance required is filter cleaning and replace-
ment.
The turbine main filter and pre-filter must be clean at
all times to provide sufficient air flow to cool the motor
and atomize the fluid. Check the filters weekly, mini-
mum. Replace the pre-filter as required.
NOTE: To check the filter, turn on the turbine and
place a piece of paper against the air intake filter. If the
air intake holds the paper in place, the filter is okay.
To clean the main filter:
1. Turn off and unplug the turbine.
2. Loosen the four main filter screws. See Fig. 5.
3. Remove the main filter and clean it by following
one of the following three methods:
Tap the filter gently on a flat surface, dirty side
down.
Direct compressed air (100 psi [7 bar] maxi-
mum) through the filter panel in the opposite
direction of the arrows on the side of the filter.
Soak the filter for 15 minutes in water and a
mild detergent. Rinse the filter until it is clean.
Air dry the filter; do not use compressed air.
WARNING
To avoid damage to the turbine and possible elec-
tric shock, never install a damp filter in the turbine.
Maintenance
Do not operate the turbine sprayer without the filter
installed.
