Expansion Vessel; Safety Valve - Effecta Lambda Operation, Service And Installation Manual

Components
Laddomat 21
A Laddomat valve should always be mounted between boiler and
tank. It´s described further on page 10.
Automatic Shunt
It´s recomended to use an automatic shunt valve to control the flue
in the radiator circuit. It feels the temperature in a special place in
the house and regulates the temperature in the radiator circuit flue.
Using an automatic shunt will significantly reduce the amount of
wood needed during a year, and your indoor climate comfort will
also improve.

Expansion Vessel

The expansion vessel normally is tested for 6bars. Highest working
temperature is 99degreees. The vessel has a preepressure of ,5bar.
The volume should be approx. 10% of the total volume of the sys-
tem. An open vessel should have a volume of 5% of the total.

Safety Valve

The safety valve will release when pressure exseeds 1,5bars. When it
opens water will drip out of it and the pressure goes down. Remem-
ber that the system is designed for a maximum pressure of 1,5bars,
and shall under no circumstanes be under higher pressure.
Shuntvalve
The shunt valve is mounted on the radiator circuit, and it´s designed
to mix the accumulatorwater and the return water from the radiator
to get the right temperature indoor. If mounting an automatic shunt
valve, read it´s instructions.
