POSSIBLE SOLUTIONS

Vac requires 110V to operate. Check to be sure
that 110V are present. If voltage is not present
check all breakers . If all breakers are good - call
an electrician.

Check for 110V Power at Breaker inside Cabinet.

If power is found, then check for 24V coming out
of Transformer (Yellow/Blue wires)

If you do not have 24V then the Transformer is
bad.

Check for clogged hose - Remove hose - place
hand over hole in vac - is there suction now?

If there is still no suction - check to be sure both
motors are running. (Remember - when one
motor runs the other motor will turn due to the
passing of air).

Check screen on bottom for dust build up - if there
is a build up - remove dust and replace motors.

If you still do not get results - clean filter bags (dirty
filter bags will not allow air to pass through them)
leaving you with little or no suction. Also, dirt
doors with bad gaskets do not make a good seal
leaving you with little or no suction.
