Water volume and expansion vessel pressure
Note :
(a) The expansion vessel is 2 liter and 1.5bar pre-pressurized for 4/6/8kW unit; 3 liter and 1.5bar per-
(b) pressurized for 10/12/14/16kW unit ;
(c) Total water volume of 44 liter is default for 4/6/8kW unit and 66 liter for 10/12/14/16kW unit; if total water is
changed because of installation condition, the pre-pressure should be adjusted to secure proper operation.
If the unit is located at the highest position, adjustment is not required;
(d) Minimum total water volume is 20 liter;
(e) To adjust pre-pressure, use nitrogen gas by certificated installer.
