5 Troubleshooting
Issue Solution
Air passes through the
pump without cycling
• If air passes through the pump (P56) 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 (CV14QF-S) 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 (AC120V-1HP-CAT) 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
(STR38-IL) must always be used.
