’variomat 2-2’ with VG basic vessel
and VW thermal insulation
The level gauge should only be mounted when the VG basic vessel is in its final position. The transport protection
(wooden block) at the vessel foot of the basic vessel must be removed and replaced with the pressure cell (23).
Above a vessel size of 1000 l (Ø 1000 mm), the level gauge must be mounted using the screws supplied.
Apply the VW thermal insulation around the VG basic vessel
and close with the zip. We recommend insulating the VG
basic vessel and the expansion lines against the loss of
heat, especially in heating systems. There is no need to
insulate VG secondary vessels.
Since there is an air space between the diaphragm and the
vessel wall, there is no need to insulate the lid.
In the case of possible formation of condensate, we
recommend on-site insulation.
C A U T I O N
The following points must be noted to ensure correct operation of the level gauge:
– The vessel must be freestanding and vertical on a stable and level surface (do not bolt down, set in concrete,
and so on.).
– Auto-zeroing of the filling level may only be performed with the vessel aligned and empty.
– The vessel foot should not be subjected to any impact loads once the level gauge has been mounted (for example
during installation/plumbing of the vessel).
– Always connect the VG basic vessel and the first VF secondary vessel flexibly using the connection sets supplied.
Non-compliance with these instructions may cause measuring errors as well as malfunctions of and damage to the
level gauge.

– Make sure the system is
freestanding!
– Do not tilt the pistons!
– Remove the transport
protection
– Push the oil pressure cell
underneath and bolt onto
the foot in the case of
