The boiler connection system "PWW" allows an economical and time-saving connection of the
boiler to the pipework.
The individual components of the "PWW" are supplied loosely connected. The connection has
to be tightened after installation of the pump.
The circulation pump and the tailpipe sets are to be ordered separately. The connection box of
the pump must be on the left hand side of the actuator (9 o'clock position).
The insulation shells are part of the packaging. When leaving the factory, the supply pipe is on
the right hand side.
Installation of the supply pipe of the PWW on the left hand side is carried out as follows:
Unscrew flanged pipe with check valve on the return (left hand side of the PWW) and screw it
back on the right hand side. Install pump on the left hand side.
The switching box of the pump must be on the right hand side of the actuator (3 o'clock
position). Pull out and interchange the red and blue plugs on the front of the insulation.
Red = Supply, Blue = Return.
A modification to the mixing valve is not required.
