5. CONNECTION TO THE WATER NETWORK AND HEAT
The tank and assemblies required for its operation must be connected to the
water network according to Figure 10.2.; 10.3.; 10.4.
5.1.
It is forbidden to connect the appliance using a hose!
For cold and hot water connections, steel or red copper pipe rated for 1 MPa
nominal pipeline pressure, heat resistant plastic pipe rated up to min. 100°C
or flexible connection may equally be used.
When connecting to a copper pipeline, the use of insulating spacers is
compulsory.
One spacer must be inserted on the hot water pipe of the container
immediately, while the other one on the cold water pipe, between the
already installed assemblies and the copper water pipeline. If no spacer is
used at the connections, we neither provide guarantee for failures
attributable to the corrosion of the threaded tank pipes, nor assume liability
for damages caused by the same.
It is forbidden and dangerous to expose the tank to pressures
5.2.
The valve must be installed on the cold water pipeline IMMEDIATELY
before the container observing the flow direction indicated by the arrow.
Before installing the valve, the cold water pipeline must be carefully flushed,
in order to avoid damages due to possible contaminations. The valve may
leak, whereby the outlet should be directed vertically downwards, and the
blow-off button should be accessible. This pipe must be left open towards
the air space. The drainage pipe must be directed downwards (from the
appliance) into a frost free room, and free drainage must be ensured
towards the air space. To ensure the proper operation of the water heater,
carefully observe the commissioning drawing. You can direct leaking water
into the sewage network in a visible way.
The safety valve is not included in the accessories of the appliance
