INSTALLATION
MONITORING AND DISPLAY
During both the first installation and maintenance ensure THERE IS NO POWER in the line
During both the first installation and maintenance ensure the plant is UNPRESSURED
DO NOT OPEN THE COVERS OF THE INVERTER
In addition ensure that the electricity supply has protections and in particular has a differential switch of great sensitivity (30 mA
in class A for domestic applications and in class B for industrial applications) and grounding in conformity with the regulations.
Verify that the data on the plate are those desired and that they are adequate for the installation.
Install TISSEL-100 in a place:
– protected from external agents
– ventilated, free of excess humidity or too much dust
– where it does not suffer from harmful vibrations or mechanical stresses from the tubes connected to it.
POSITIONING OF THE PRODUCT
• Fix the unit with screws onto a solid horizontal base.
• If the pump has to be installed externally where it might freeze protect it to avoid freezing. Freezing of the liquid contained in
the body of the inverter causes irreversible damage.
IMPORTANT
For the correct functioning of the TISSEL-100 the installation of an adequate expansion tank is absolutely necessary.
The expansion tank:
• Accumulates water under pressure in order to reduce to a minimum the start of the pumps.
• It is indispensable in the presence of small losses of the installation.
• It absorbs eventual over-pressures coming from the plant.
• The minimum volume required in litres (for models with a membrane) is indicatively equal to 10% of the maximum flow rate
of a single pump, expressed in l/min.
Example of a standard application: Qmax = 80 l/min Æ V = 80 x 10% = 8 litres (rounded up by excess to the commercial size)
• Pre-load pressure (with an empty plant): approximately 70% of the work pressure:
Example: Pset = 4 bar
Æ Pre-load pressure = 4 x 70% = 2.8 bar
ELECTRICAL CONNECTIONS
• The electric connections between the pump and the inverter are implemented in full in the factory and therefore for its func-
tioning nothing needs to be done.
• TISSEL-100 is connected to the electricity supply (230 V/50 Hz) by means of an electric cable.
