3.2 VICTRIX PRO V2 3555606880 EU ADDITIONAL BOILER HYDRAULIC MANIFOLD KIT INSTALLATION
Remove the lower protecting plate (15) of the boiler (16).
Pre-mount the tting unit (12) and nipples (7) on the 3-way valve (11), interposing suitable sealing material such as oakum or similar.
Pre-assemble the tting unit (12) on the system shut-o valve (13) by interposing suitable sealing material such as oakum or similar.
Pre-assemble the nipples (7) on the non return valve (5) by interposing suitable sealing material such as oakum or similar.
Pre-assemble the non-return valve (5) to the manifold (1) by interposing suitable sealing material such as oakum or similar.
When installing the non-return valve (5) make sure that the arrow on the body points towards the system return pipe (10) as shown in gure 8.
Connect the previously preassembled tting assembly (12) and 3-way valve (11) to the system ow (M) of the boiler (16), making sure to interpose the corresponding
gaskets (8).
Connect the preassembled ball valve (13) and the 3-way valve tting assembly (12) to the system return (R) of the boiler (16), making sure to interpose the corresponding
gaskets (8).
Connect the insulated ow pipe (9) to the 3-way valve (11) and the insulated return pipe (10) to the ball valve (13), interposing the seals (8).
Connect the manifold (1) to the ow pipe (9), interposing the gasket (8).
Connect the manifold (1) to the return pipe (10), interposing the gasket (8).
Proceed in this way for subsequent boilers, making sure to place the relative gaskets (2) between the manifold connections (1).
Upon completion of the connections, proceed by tting insulation (3) and (4) on the manifolds (1).
Mount the insulation (6) on the non-return valve (5) and the insulation (14) on the ball valve (13).
Ret the lower boiler protecting plate (15).
Aer the 1st temperature test, check the tightness of all the pipes.
e components downstream of the system, such as the expansion tank, must be sized according to the ow rate of the system.
When assembling the kit with free outputs on the le side, perform the installation as shown in gure 7.
To empty the boiler, proceed as follows:
1. First close the ball valve by turning the lever clockwise.
2. en close the 3-way valve by turning the lever anti-clockwise.
Before closing the system shut-o valves, the boiler must be switched o.
