TROUBLESHOOTING:
Unit will not start
Check system’s power connection.
Turn On/Off switch ON for operation.
Check that voltage selector module is set for source
voltage.
Check fuse. If blown, replace with 6A/125V medium
time delay fuse for 120V operation, or a 4A/250V slo-
blo fuse for 230V operation.
Unit starts but blows fuse
Check that voltage selector module is set for source
voltage.
Check vacuum waste container. If full, immediately
empty to continue operation.
Check vacuum hose assembly for blockage.
Check that fuse is correct for source voltage.
No water coming out
Check water supply tank for water level and verify
that cap is tight.
Depress foot switch for 5+ sec. to pressurize supply
tank.
Ensure the handpiece air control knob is not open
(turned clockwise) all the way.
Insufficient vacuum
Check vacuum waste container. If full, immediately
empty to continue operation.
Check vacuum hose assembly for blockage.
Check that waste container lid is properly seated and
tightly secured.
Insufficient handpiece operation
Check that handpiece coolant ON/OFF toggle is
“ON”.
Check that air control valve is turned up adequately.
Check that handpiece tubing is untangled and not
crimped.
Check handpiece connection for missing gasket.
Compressor makes a chugging sound and does not
start up properly
Check for sufficient power source and avoid long
light-grade extension cords (Refer to Figure 8 Exten-
sion Cord Recommendations).
EXTENSION CORD RECOMMENDA-
TIONS:
Use only a 3-wire extension cord that has a 3-blade grounding
plug. Connect extension cord plug to a matching 3-slot
receptacle. Ensure that the extension cord is in good condition
and that its gage wire is the correct size wire to carry the current
this product will draw. An undersized cord is a potential fire
hazard and will cause a drop in line voltage, resulting in loss of
power and causing the product to overheat. Figure 8 indicates
the correct size cord for the length required and the ampere
rating listed on the product nameplate.
If in doubt, use the next
heavier gage cord. The smaller the gage number, the heavier
the wire gage.
Disposing of your old product
Each Member State in the European Union (EU) requires that
the waste from electrical and electronic products be disposed
of separately from normal household waste. This includes
electronics, metals and electrical accessories, such as signal
cables or power cords. Products in this category carry the symbol
below.
Contact your local disposal authority and comply with the correct
disposal method and follow national guidelines for unit disposal.
