ctivate

the volume control switch in both directions, when

Technical Information

VOLUME CONTROL VALVE TES

If you don't feel vibration in the flow control valve, find

and cut the two wires that come from the electronic

control and to the flow control valve. This is to isolate

these circuits in case there is a short in the flow

control valve that may affect the following test.

These wires are 12V DC and are (bidirectional).

Using a test meter, measure between the two wires

and verify 12V DC is present when the volume control

switch is activated. The (polarity) should change in

relation to the volume control operation - increasing or

decreasing the volume.

MANUAL VOLUME CONTROL ADJUSTMENT

If voltage is present but the polarity does not change,

it is possible the problem is within the electronic

control. Check for faulty wiring or a bad connection in

the system.

If voltage is present and the polarity changes as

indicated it is possible the problem is within the flow

control valve. The electric motor has either failed or is

mechanically stuck.

Cut the volume control valve power cord.

Loosen the flow control valve retainer screw (orange

circle) in order to free the housing. Adjust the volume

by rotating the housing in either direction for desired

setting.

Retighten retainer screw after making desired volume

adjustment.

This manual adjustment procedure can be used till the

defective flow control valve is replaced.

Mark the outer volume control valve housing and nut

to relocate the valve back to its normal position if

needed.
