20. Pipe Exhaust
We suggest installing
automatic exhaust valve
in pipe to ensure smooth
emission of the system
gas. If the pump is used
in household heat sys-
tem. Switch on the water
source and turn on each
tap, then the gas can be
exhausted.
21. Pump Exhaust
The gas within the pump must be also exhausted after the system being exhausted to ensure
the pump to work in best condition.
Note: care must be taken not to splash the water column or drops go into the junction box to
avoid the electric fault.
