Initial pressure and max height difference
The initial pressure of the pressure expansion vessel must
be dimensioned according to the maximum height (H)
between the vessel and the highest positioned radiator,
see figure. An initial pressure of 0.5 bar (5 mvp) means a
maximum permitted height difference of 5 m.
If the standard initial pressure in the pressure vessel is not
high enough it can be increased by filling via the valve in
the expansion vessel. The expansion vessel's standard initial
pressure must be entered in the check list on page 40.
Any change in the initial pressure affects the ability of the
expansion vessel to handle the expansion of the water.

Manual shunting
When HBS 16 is set to emergency mode, the heating
control system is not in operation, and manual shunt op-
eration is required.
1.
Depress and lock the button on (QN11).
2.
Turn the mixing valve to the desired position by hand.

Emptying the vessel
The vessel in HE 30, HEV 300, HEV 500 is emptied by
opening the valve (QM1) and safety valve (FL2).
NOTE
When HEV 300/HEV 500 is emptied via the valve
(QM1), some water will remain in the coil and in HBS
16.
This means that there is a risk of the heat exchanger,
pipes and valves freezing at low temperatures as well
as a hygienic risk for the coil in the hot water section.

Recommended installation order
1.
Connect HBS 16 to the climate system and to the tank.
Connect cold and hot water lines as well as any extern-
al heat sources to the tank. See page 22. Also see
docking descriptions on page 26 and further on.
2.
Install the refrigerant pipes according to the descrip-
tion on page 23.
3.
Connect the load monitor, outdoor temperature
sensor, any centralised load control and external con-
tacts as well as the cable between HBS 16, the tank
and AMS 10-16. See page 33.
4.
Connect supply to HBS 16. See page 31.
5.
Follow the commissioning instructions on page 37.
