Checking the water level

For systems with a header tank, set the red marker
on the pressure gauge to the required system
pressure. On sealed systems the pressure gauge
marker must be within the green range.

Check the system water level; where required
replenish with water and vent the entire system.
If water is lost during operation, replenish it slowly
and vent the entire system. If the system frequently
requires topping up, investigate the cause and rectify
immediately.
