Checking the safety valves

FIGHTER 310P has three safety valves, one for the
heating system and two for the water heater.
The safety valves must be checked regularly. Check
one valve at a time as follows:
■ Open the valve.
■ Check that water flows through the valve.
■ Close the valve.
■ The heating system may need to be refilled after
checking the safety valve (52), see the section
"Commissioning and adjustment" – "Filling the
heating system".

Pressure gauge

The pressure gauge reading should be between the
initial pressure of the expansion vessel (normally 0.5
bar) and 2.5 bar (25 mvp). See "Commissioning and
adjusting"

Extract air temperature

Check that the temperature of the extract air (channels
5) is clearly lower than the room temperature when the
compressor is operational, also see section "Dealing
with malfunctions" "High extract air temperature". It is
normal that the extract air temperature varies.
