INSTALLATION MANUAL
7 Storage and transport
The device must always be stored in the manu-
facturer’s original packaging. All the instructi-
ons stated on the outside of the packaging
must be followed. The storage space must be
dry and arranged in such a way as to prevent
the packaging from being damaged. During
transportation the original packaging must
remain undamaged in order to protect the devi-
ce. When placing the box into the vehicle, do
this in such a way that the box cannot shift. Keep
the device contained in the packaging, as long as
possible until you have reached the location
where the installation is to take place.
7.1 Contents of the packaging
The packaging contains the following items:
- Waterheater
- Manual
- Quick installation guide
- Connecting set
7.2 Packaging and the environment
In order to save the environment, you must:
• Dispose of the cardboard elements at a
local assembly point for recycling.
• Dispose of the remainder of the packaging
through the regular disposal channels.
• Or give the box a second life by transfor-
ming it into a storage box.

9.3 Connecting conditions
- Electricity connections are present or can
be installed;
- An earth-connected wall socket is used for
the input;
- Water conduits are present or can be installed;
- A cut-off valve is never placed between the
inlet combination and the waterheater;
- The expansion water from the relief valve of
the inlet combination is carried off via the
drain pipe to the sewer;
- The supplied inlet combination has an ope-
ning pressure of 6 bar (and is equal to the
operating pressure of the waterheater);
- The 1 meter long flexible connection-hoses
are allready mounted in the factory and
tested for leakage. It is not recommended to
loosen them.
9.4 Possible accessories
System under pressure
- A pressure reducing valve* is necessary
if the water supply pressure is higher
than 5 bar;
Unpressurised system
- A unpressurised single hole mixing tap.*
* Not supplied!
• Connect the cold water connection of the
tap with the cold water supply;
• Connect the hot water connection of the
waterheater (10 mm compression coupling)
with the hot water connection of the tap.
Unpressurised system (Fig. 2.2)
• First carefully flush out all the pipes connec-
ting with the waterheater (especially impor-
tant in case of newly-built houses);
• Close off the main cock of the water main;
• Connect the cold water connection of the
waterheater (G 1/2” swivel) with the cold
water pipe of the tap;
• Connect the cold water connection of the
tap with the cold water supply;
• Connect the hot water connection of the
waterheater (10 mm compression coupling)
with the hot water connection of the tap.

10.3 Connection drain pipe
(with pressurised system)
• Connect the drain T-joint in the drainage
pipe and attach the flexible drain pipe
according to the diagram (fig. 2.1 and 2.3).
Do not forget to place the Tie-wrap to gua-
rantee stench seal.
The (main-) drainpipe on which the
outlet of the relief valve on the inlet
combination is connected, must be
placed in a continuous downward
direction in a frost-free environment.
10.4 Filling the waterheater
• Open the hot-water tap;
• Open the stop cock of the inlet combina-
tion (with a system under pressure);
• Open the main cock of the water main;
• Have the waterheater properly flushed through;
• Check the installation for leakage.
10.5 Connections electricity
The waterheater must be completely
filled with water and the installation
must be free from leaks before a
connection with the electricity grid
can take place.
The device has a 1,5 metre long cord for a con-
nection with an earth-connected wall socket.

10 Installation
10.1 Installation of the waterheater
• Place the device on a flat surface with nothing
in between.
10.2 Connections water main
When installing swivels and compres-
sion couplings, always use 2 open-end
spanners in order to prevent bending
and torsion on the pipes and acces-
sories.
The new flexible connection hoses that
are supplied with the Modesto should
be used to install the new water heater.
Old connecting hoses must not be re-
used.
Pressurised system (Fig. 2.1 and 2.3)
• First carefully flush out all the pipes connecting
with the waterheater (especially important in
case of newly-built houses);
• Close off the main cock of the water main;
• Connect the cold water connection of the
waterheater (G1/2” swivel) with the inlet-
combination;
• Install a pressure reducing valve upstream of
the inlet combination if the water main
pressure is higher than the closing pressure
of the inlet combination;
• Install the inlet combination on the coldwater
supply or -with the Modesto Hotfill - on
the hot water pipe (Hotfill pipe) of the
main hot water provision;
9 Preparations for installation
9.1 Local installation instructions
When installing the waterheater, you must
follow the locally applicable installation
instructions regarding, for example, the
electricity company and waterworks.
9.2 Installation conditions
Determine the place where the waterheater is to
be installed on the basis of the examples on p. 6
(fig. 6, 7, 8 and 9) and the situation in your kitchen.
Take into account the following points:
- Waterheater, inlet combination, water con-
duits and drain pipes are located in a frost-
proof space;
- The ground is level and can support the
waterheater with contents;
- Make sure the waterheater stays reachable
for service and maintenance.
