Functional description
The SV-3 storage tank transfer set is used to connect an
additional SolvisStrato stratified buffer tank as a follo-
wing buffer tank (ES) to an existing SolvisStrato as the
leading buffer tank (FS) in the SolvisVital 3 system. You
can use a motorised four-way switching valve to charge
from the leading buffer tank to the following buffer tank,
or vice versa. When you install the system, pay attention
to the position and installation direction of the non-
return valve (RV) (spring-loaded gravity brakes), see
Fig. 7.

1.3 Installation
Laying the piping
1. Connect the pump (6) to the 20 mbar gravity brake
(5), the ball valves (4), the adjusting valve (3) and the
4-way mixer (1) as shown. In the process, make the
on-site pipe connection (2) between the adjusting
valve and the 4-way mixer.
2. Lay pipes from the 4-way mixer and the gravity bra-
kes (7) to the storage tanks according to the system
diagram (see
