3.3 INSTALLATION OF HYDRAULIC MANIFOLD KIT 2 BOILERS IN SERIES VICTRIX PRO V2 100120150 EU
Remove the lower protecting plate (20) of the boiler (21).
Pre-mount the tting units (18) and nipples (13) on the 3-way valves (16), interposing suitable sealing material such as oakum or similar.
Pre-assemble the tting units (18) on the system shut-o valves (19) by interposing suitable sealing material such as oakum or similar.
Pre-assemble the nipples (13) on the non-return valves (12) by interposing suitable sealing material such as oakum or similar.
Pre-assemble the nipples (1) on the non-return valves (12) by interposing suitable sealing material such as oakum or similar.
When installing the non-return valves (12) make sure that the arrow on their body points towards the system return pipe (15) as shown in gure 10.
Connect the previously preassembled tting assembly (18) and 3-way valve (16) to the system ow (M) of the boiler (21), making sure to interpose the corresponding
gaskets (10).
Connect the preassembled ball valve (19) and the 3-way valve tting assembly (18) to the system return (R) of the boiler (21), making sure to interpose the corresponding
gaskets (10).
Connect the insulated ow pipes (14) to the 3-way valves (16) and the insulated return pipes (15) to the ball valve (19), interposing the seals (10).
Mount the blind ange (5) on the manifold (1), interposing the gasket (2).
Connect the manifold (1) to the ow pipe (14), interposing the gasket (10).
Connect the manifold (1) to the return pipe (15), interposing the gasket (10).
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 the insulation (3) on the manifolds (1) and then the adhesive manifold end caps (6) with the collar insulation
(3+4) on all manifold ends (1).
Mount the insulation (11) on the non-return valves (12) and the insulation (17) on the ball valve (19).
Ret the lower boiler protecting plate (20).
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 9.
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.
VICTRIX PRO V2 boilers have an electrical insulation rating of IPX5D. However, if installed outdoors, it is advisable to insulate the relative pipes and
protect the kits from the weather.
Boilers must be installed in their original congurations and with their original battery kits. Immergas declines all liability whenever the installation technician does
not use original Immergas appliances and kits, or uses them improperly.
