Maintenance of the valves
Humidity in the valves can cause freezing
and sticking of the valves during operation.
To prevent this both valves in the block can
be easily removed and cleaned with ethanol.
Remove both steel valves with a screw
driver. The 2nd steel valve is located
underneath the 1st valve.
Before inserting the valves again, check that
the ball inside the valves is free.
