1.1 Installation prescriptions
CAUTION
Always foresee the installation of an emergency relief valve and a properly
dimensioned expansion vessel. These devices are not built in the AWS unit.
Where the storage tank should be installed lower than the AWS unit, foresee the
installation of a jolly valve at the higher point of the water piping.
Failure to observe these prescriptions could result in malfunction and/or damage to the
unit.
Always foresee the installation of a buffer tank, fitted with anti stratification
pipes, which size should be adequate to the AWS unit capacity.
Failure to observe these prescription could result in malfunction and/or damage to the
unit.
Always check that the Y-shape water filter (supplied with the unit) is installed on
the primary circuit return pipe. In case of multi units plants, install one filter each
AWS unit. Install the filter to not less than 50 cm from suction of the pump.
Failure to observe this prescription makes the warranty no longer valid and could result
in malfunction and/or damage to the unit.
WARNING
Welding, refrigerant gas and water piping installation should be always
performed by specialised technical personnel in accordance with instructions
and prescriptions mentioned in the present manual.
Failure to observe this prescription makes the warranty no longer valid and could result
in malfunction and/or damage to the YOSHI AWS unit.
