The volume of balance tank(8) should be greater than 40L(for 5~9kW unit, greater than 20L) The drain valve (6) should
be installed at the lowest positon of the system. An independent backup heater can be selected and installed in the door.
Temperature sensor T1B must be installed at the outlet of AHS, and connect to the corresponding port in the main
control board of hydraulic module(refer to 9.3.1 Main control board of hydraulic module), pump(10) should be
controlled by outdoor unit and connect to corresponding port in the outdoor unit(refer to 9.7.6 Connection for other
