TROUBLESHOOTING:
EXTENSION CORD RECOMMENDATIONS:
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.
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).
