Install lter unit and air tubes
1. Mount the lter unit in the holder where it is
easy to reach and with the lter unit lid in the
upward direction (see gure).
2. An open lter unit control valve lowers lifting
speed and may be used by new operators.
Verify that the valve is closed before continu-
ing (a).
3. Connect section one of the air tube between
the vacuum pump and the lter unit with
hose clamps (use a clamp torque of 5 Nm)
(b).
4. Connect section two of the air tube between
the lter unit and the lift tube top swivel with
hose clamps (use a clamp torque of 5 Nm)
(c).
VM0/40/50 come with a reducing socket
which is placed inside the lter inlet. The l-
ter inlet and outlet are marked with an arrow.

• Take care to mount the lter unit in the correct orientation during reassembly. Damage to the
pump may occur if the lter unit is mounted upside-down.
• Make sure to install all air hoses as straight as possible. Sharp hose bends will reduce lifting ca-
pacity and may cause the pump to overheat.
• Do not use more than 30 m of hose for the entire installation. Lifting capacity will be reduced and
may cause the pump to overheat.
