1.11 Instructions for installation and connection of the unit
1.11.1 Characteristics of the location
Before locating the unit, make sure you have received the appropriate product by checking the specifi‐
cations described on the outside of same.
The unit should be placed on a perfectly horizontal plane, making sure the base can support the weight
of the unit.
If vibration-free operation is required, the unit can be placed on a cork or similar anti-vibratory base, or
fastened to the base with anti-vibratory plates or supports.
1.11.2 Specifications for the foundation or anchoring of the unit
Where the unit is to be installed at ground level, the
characteristics of the ground it will sit on must be taken
into account.
Characteristics, such as acceptable surface firmness,
must be suitable for the foundation the unit requires.
1.11.3 Hydraulic connections
The hydraulic connections of the water inlet and outlet of the unit should be carried out respecting the
inlet and outlet directions indicated.
Galvanised iron or copper piping can be used, with dimensions no lower than those indicated, and keep‐
ing in mind the pressure drops at said connections and in the internal exchanger of the installation.
Pump dimensioning should be carried out in accordance with a nominal flow that allows an Δt within the
operating limits.
In all cases, a flow switch should be installed so as to avoid the possibility of operation without water
flow.
An adequate expansion vessel for the total volume of the water in the installation should also be installed
in the water return piping.
During the winter season, with outdoor temperatures below 0°C, take precautions to avoid freezing of
the water in the piping network.
Usually, a filling solution is applied to the circuit with an antifreeze mixture (glycol).
