SAFETY INSTRUCTIONS

Pay particular attention to the signs and their symbols
General danger to people
Warning of electrical voltage
ATTENTION!
Danger to equipment and operation
This appliance can be used by children aged 8 years or over
and by persons with limited physical, sensory or intellectual
capabilities, or with limited experience and knowledge, pro-
vided that they are supervised or have been instructed in the
safe use of the appliance and are aware of the dangers in-
volved. Children must not be allowed to play with the appli-
ance. Cleaning and user maintenance must not be carried out
by children unless they are supervised.
Before assembling, carefully read the contents of this man-
ual. The non-observance of the instructions will result in the
annulment of the warranty.

GENERAL INFORMATION

Our pressurization groups are manufactured for pumping
clean water. They must be installed in places protected from
bad weather and ice, well ventilated and in non-dangerous
environment.
Each of our groups is entirely tested in our establishments.
Upon delivery, check that the group has not suffered any dam-
age during transportation; in this case, contact immediately
the retailer. In case of claims, contact immediately the retailer
within ten days of purchase.
LIMIT OF USE
ATTENTION! Before checking the pumps priming make sure
that their max. pressure, shown on their nameplate, is com-
patible both with the system pressure and with its devices.
Furthermore make sure that eventual security valves are set
to have an higher intervene pressure than the max. pressure
of the pumps.
ATTENTION! The group is not suitable for pumping chemical-
ly aggressive or flammable liquids.
ATTENTION! Avoid any dry-operating of the motor pump.
Temperature
Maximum temperature of the pumped liquid: 40°C
Maximum ambient temperature: 40°C, (50°C per le elettro-
pompe DHR, VLR)

INSTALLATION

Assembly diagrams normally used
Fig. 1
All the assembly operations must be carried out
withgroup disconnected from the power grid.
In the case where the pressurization group is fed by a tank,
avoid any unpriming phenomena; we recommend to control
the following characteristic data:
- Static level (initial level of the well)
- Dynamic level (level reached during the group operation)
- Flow rate
- Hmax suction
To reduce losses during replenishment it is necessary to in-
stall the group as close as possible to the pumping point and
to install a suction pipe with a minor number of curvatures
that should have a sufficiently wide radius.
Even the diameter of the pipe should be calculated so as to
reduce load losses, what requires dimensions greater than or
equal to those of the pump aspiration inlet.
In order to avoid the formation of air locks into the suction
pipes, these ones must have a positive gradient, from bottom
to top, avoiding counter gradients or "goosenecks", and there
must not any air infiltration in the connections.
Connect the delivery collector to the distribution collector by
interposing vibration-damping joint. This connection can be
done either on the right side or on the left side of the collector
by displacing the blind flange or the threaded cover.
ATTENTION! It is a good rule to foresee the evacuation of wa-
ter losses in case of bad seal of joints, mechanical seal, tanks
overflowing, etc.
