6. INSTALLATION
6.3. Ambient requirements and installation site
dimensions
The customer has to prepare the installation site in
order to guarantee the right installation and in order to
fulfill the device requirements (electrical supply, etc...).
It is Absolutely forbidden to install the machine in an
environment with potentially explosive atmosphere.

6.4. Unpacking

Inspect the device in order to check any
damages which may have occurred during
transportation.
Package material, once removed, must be discarded/
recycled according to local laws of the destination
country.

6.5. Hydraulic connection

Before proceeding with hydraulic connection
make sure to prime the pump correctly.
The IDROMAT should always be installed in horizontal
position with the overmolded arrow pointing to the top,
connecting the inlet (male) directly to the pump and
the outlet (male) to the network (picture 1 chapter 10).
Do not locate the check valve at the on the exit
of the IDROMAT (picture 7). No device must
be installed between the pump and the device.
It is reccomended to apply a ball valve in the
outside of the device to isolate the IDROMAT
group pump from the net. (pictures 5-6).
It is advisable to connect the device outlet to the
system by using a hose. (picture 6)
Do not install the Idromat in systems with pumps
achieving more than 12 bar pressure at 0 flow.
The pressure created by the pump must be
normally 1 bar higher than the restarting
pressure of the device. In particular, the actual
pressure of pump and the height of water
column which burden on the device must be
checked in relation to the restarting pressure.
The head parameter must copmply with the
table in chapter 2.
6.6. Submersible pump installation
Install an auxiliary membrane tank with minimum
capacity of 20l to prevent exceeding the maximum
number of motor-startngs per hour. (picture 5) The
auxiliary tank must be swelled to a pressure of about
0,2 bar below the restarting IDROMAT pressure.
(chapter 10).
The pump does not have to operate at a flow
lower than the minimum flow indicated on the
pump plate.

6.7. Electric connection

Fasten the input/output cables by tightening the cable
gland ferrules in the lower part of the electric control
panel.
Electrical connection must be carried out only
by a qualified electrician in accordance with
local regulations.
Follow all safety standards.
The unit must be properly earthed (grounded).
Connect the earthing (grounding) conductor to the
terminal with the marking
Once the electrical connection has been
completed, remove any pieces of wire, sheath,
washers or any other foreign bodies that may
be found inside the electric control panel.
Bad connections may spoil the electronic
circuit.
6.7.1. Power supply connection
Follow the indications reported in the electrical
scheme (paragraph 10).
6.7.2. Electric motor connection
For single-phase motors, the motor power
cable must be connected to the terminal block,
while for three-phase motors, the motor power
cable must be connected directly to the output
terminals of the contactor. (paragraph 10).
