Central vacuum systems

Every dust separator is equipped with a by-pass

valve for the vacuum of air which acts when in the

piping there is too much suction power.

•

On the systems with 2,2 kW motors the by-pass

valve on the dust separator should be always

closed.

•

The by-pass valve is used only on the systems

with 5,5 kW motors, when on a motor just one

operator is working. The excess of vacuum power

is compensated by the by-pass valve Check that

the valve is open and adjust eventually the bolt

for a maximal efficiency.

Steps for the adjustment of the by-pass valve

1. with a wrench unscrew the bolt of the cover 1

and remove the metal cover and remove the

soundproof cover 2.

In the case that in the piping some by-pass valves

will be installed for the self-cleaning of the lines,

close the valve on the dust separator and adjust

such valves as described in the paragraph “Check

of the functioning of the by-pass valve on the dust

separator”.

Steps for the adjustment

1. After having removed the soundproof cover of

the valve, start the system by inserting 2 flexible

hoses into the inlet valves.

2. Adjust the valve as described in the paragraph:

“Check of the functioning of the by-pass valve on

the dust separator”.

valves adjustment

2. start the system by inserting the 2 flexible hoses

into the inlet valves and vacuum by both of them.

3.adjust with a wrench the by-pass valve 3, by

opening it until when an air infiltration could be

heard

4. remove one flexible hose from the inlet valve and

check that the inlet valve starts working again

5. close the valve to the closing

6. reassemble the soundproof cover
