EHVH04CB3VF
Addendum to the documentation set
EHVH08CB3VF
We advise to first carefully read this addendum and only then to consult delivered manuals and proceed with installation of the unit.
For this floor standing low temperature heat pump EHVH04CB3VF or EHVH08CB3VF, instructions in the manuals delivered with the unit are these
of the EHVH04CB3V or EHVH08CB3V.
All delivered manuals as well as the Installer reference guide and User reference guide referred to in delivered manuals apply, but there are some
exceptions and attention points for the “F”-version units.
These exceptions and attention points are described in this addendum.
Differences mainly relate to
1) water piping and refrigerant piping connections (see pictures in this addendum);
2) the built-in 12 l flow-through vessel under the domestic hot water tank (which impacts on the minimum water volume of the installation);
3) lay-out of the internal piping;
4) impact of these differences on technical specification drawings. The correct versions are therefore added to this addendum.
There is no difference for everything related to the user interface, the software or the operation of the unit. All information in the delivered manual
related hereto is therefore correct.
1. Water piping connections and refrigerant piping connections
The following picture illustrates the water piping connections of your unit (chapter “To connect the water piping”). Analogous pictures in the
EHVH04/08CB3V manual are to be neglected.
The following picture illustrates the refrigerant piping connections of your unit (chapter “To connect the refrigerant piping to the indoor unit”).
Analogous pictures in the EHVH04/08CB3V manual are to be neglected as well.
2. Minimum water volume (chapter “To check the water volume and flow rate)
ONLY applicable for EHVH04+08S18CB3VF
The system does not require a minimum water volume. Since an extra flow-through vessel is built into the unit, the total water volume in the
installation can be 0 l. It is however required that when all heat emitters are closed, the user interface displays a minimum water flow of 15 l/min.
INFORMATION
Critical processes or rooms with a high heat load may require extra water.
NOTICE
When circulation in each space heating loop is controlled by remote controlled valves, it is important that a minimum water flow of 15 l/min is
guaranteed, even if all valves are closed.
