TROUBLESHOOTING GUIDE
ISSUE
SOLUTION
Air passes through the pump
without cycling
If air passes through the pump (687001) without cycling, the pump needs to be
replaced.
The solution backs up into the
air regulator
If solution backs up into the air regulator, the check valve (683302) needs to be
replaced.
The unit operates at a reduced
pressure
Check the discharge tubing to ensure that there are no kinks that could obstruct fluid
flow.
Check for proper air pressure on the air gauge and adjust the air regulator if needed.
The air regulator is factory set at 50 psi. Operating pressure is 50 psi.
Check the air compressor (682401) to confirm sufficient air pressure is being
supplied.
If the air supply is 50 psi (3.4 bar) or above, check the air gauge, which should read
near 50 psi (3.4 bar). If the air gauge reads more or less than 50 psi (3.4 bar), adjust
the pressure by turning the knob on the top of the air regulator. Check the chemical
suction line and strainer for debris or damage. Clean or replace as needed. To
prevent damage to the unit, the strainer (688501) must always be used.

ISSUE
POTENTIAL CAUSE
SOLUTION
The compressor stopped and
does not start.
Overloaded because of motor
overheating.
Check that the main voltage corresponds to
specifications. An extension cord that is too thin
or too long can cause a voltage drop and cause the
motor to overheat. Allow the motor to cool down.
Use heavy duty extension cords. Insure that the
compressor is plugged into a socket as close as
possible to the consumer unit or fuse box.
Motor windings are burned out.
Contact Technical Service.
The motor does not start and
makes a humming noise.
Low voltage supply to the motor. Check that the main voltage corresponds to
specifications. An extension cord that is too thin
or too long can cause a voltage drop and cause the
motor to overheat. Allow the motor to cool down.
Use heavy duty extension cords. Insure that the
compressor is plugged into a socket as close as
possible to the consumer unit or fuse box
The compressor is noisy with
metallic clangs.
Compressor head gasket broken
or valve plate faulty.
Stop the compressor and contact the dealer.
Compressor has a worn or
broken piston ring.
Stop the compressor and contact the dealer.
Compressor has a worn or
broken cylinder ring.
Stop the compressor and contact the dealer.
