Dimensioning expansion vessel

The expansion vessel volume must be at least 5% of total water
volume in the circulation system.

Initial pressure and max height difference

Recommended maximum height diﬀ erence between expansion
vessel and the highest point in the system is 5m.
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 diﬀ erence 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 User’s manua1.
Any change in the initial pressure affects the ability of the
expansion vessel to handle the expansion of the water.
Consult local distributor in case height diﬀ erence exceeds 5m.

Recommended installation order

1. Hang indoor unit and control unit to appropriate position

and connect indoor unit and tank unit.

2. Connect indoor unit to climate system, cold and hot water

lines as well as any external heat sources. See page 14.
Also see docking descriptions on page 23-24 and further
on.

3. Install refrigerant pipes according to the description on the

Installation manual for outdoor unit.

4. Connect current limiter, any centralised load control and

external contacts as well as the cable between indoor unit
and outdoor unit.

5. Connect incoming electricity to indoor unit and/or outdoor

unit. See page 29.

6. Follow the commissioning instructions on page 30-41.
