INSTALLATION
CAUTION! FOR ALL DIAMANT 2000 / DIAMANT PRO ACTUATORS
nce installed, the actuator connection should not be at the bottom of the valve. When the valve
works with low-temperature fluids (potential frost formation on the valve stem) or with high-tempe-
rature fluids (danger of actuator overheating), it is advisable to install it in the correct position, as
shown in the picture.
2-WAY BALL VALVE:
The 2-WAY Diamant 2000 / Diamant PRO have no constrained flow direction,
therefore their installation is not particularly difficult: in fact, the cut-off is made up of a ball with a
through hole. The actuator is supplied in the open position. The installation should be carried out as
shown in the picture.

The ball valve is supplied in POSITION 1. Referring to the ball valve as shown in the picture, the com-
municating ways are the LEFT and the BOTTOM ones.
During the operation, the fluid flow is progressively cut off on the LEFT side; the flow remains inter-
rupted for a few seconds and then is progressively opened again, on the RIGHT side. The actuator
rotates 180° and the ball rotates counter clockwise.
Now the communicating ways are the RIGHT and the BOTTOM ones.

BY-PASS BALL VALVE
The BY-PASS type ball valve should be used in heating systems when the fluid has to be intercepted,
allowing a limited flow between outlet and return.
The ball has a through hole and it is faced; therefore, in the open position, the operation is similar
to that of a two-way ball valve. In the closing position, the faceting generates the BY-PASS, allowing
the communication between the intercepted way to the central one.

ACTUATOR’S OPTIONALS
Diamant 2000 and Diamant PR actuators can be provided with emergency manual override on the
top (see picture 1) or lever on the spacer for insulation (the spacer is also available without lever for
manual override, see picture 2).

ATTENTION
The valve can be manually operated only when
electrically disconnected or if the actuator is bro-
ken. If the valve is blocked, please follow below
instructions:
• disconnect the actuator
• remove the actuator
• try to move the ball using a screwdriver or a
wrench suitable for the valve rod.
We would recommend not to overstress the valve
to avoid damages to the body or to the actuator’s
connection. If the ball remains blocked, remove
and replace the valve.
CABLE GLANDS SIDE
Please proceed as per following instructions and be careful
to respect positioning of all components:
1.Place the actuator with cable glands oriented towards you
and put the spacer with the vertical connection piece on the
right side.
2. With the actuator in open position, fix the central rod
paying attention that the lever for the manual opening is
opposite to the cable glands.
3. Tighten the screws to fix the spacer between valve and
actuator.
4. Electrically connect the actuator and make it open and
close to test it works properly. Looking the actuator from
above, you will see the lever moving anticlockwise from
open to close position.
ATTENTION:
Not compliance with the provisions above may cause dange-
rous situations for operators and/or the system integrity..

ELECTRICAL CONNECTIONS
TECHNICAL FEATURES OF THE ACTUATOR
Before making the electrical connections the supply power must be properly disconnected by quali-
fied personnel, according to the diagram shown under the cover.
To make the connections, unscrew the screws and remove the housing cover in order to access the
terminal strip and the printed circuit board. Remove the side plug which closes the cable gland hou-
sing, screw the cable gland and proceed to the electrical connection. During the electrical connection,
tighten the cable in the cable gland and make sure it is properly placed (fig. 2-3), close the cover
tightening the screws; the seal must fit perfectly in its housing (fig. 1).
Tighten the screws with a manual screwdriver.
Note: any electrical connection which does not comply with the attached diagrams can seriously dama-
ge the equipment.

The electrical systems must be planned taking into account the environment they will be installed
into. The IP class protection of electrical components indicates its level of protection against the
penetration of solids and liquids.
The actuators were designed to have an IP65 (Diamant 2000) and IP67 (Diamant PR )electrical pro-
tection (it is recommended to keep away from direct sunlight and to stick to the allowed temperature
range).
All the other equipments must be earthed.
Moreover, thermo-magnetic switches, fuses and circuit breakers must be installed upstream the actua-
tor, in order to ensure the compliance with the safety condition required by the existing laws.
ALL DIAMANT 2000 / DIAMANT PR M T RIZED VALVES ARE EQUIPPED WITH AN “ALL IN ONE”
SYSTEM, which allows to set the 2-POINT or 3-POINT electrical control with a jumper-type selector,
according to the user’s needs (as shown in the pictures below).
ELECTRICAL FEATURES:
CAUTION
In case of replacement, if the 3-POINT actuator version is earlier than the ALL-IN-ONE one, reverse
the connection on the terminal strip 2& 3.

DIAMANT ELECTRICAL CONNECTIONS
The “a” figure shows the connections of the 2-POINT actuator. The fixed phase must be connected
to terminal 2; at the same time, the phase on terminal 3causes the valve to open, whereas cutting
the phase on the same terminal, it closes (automatic electrical closing).
The “b” figure shows the connections of the 3-POINT actuator. If the phase is present on terminal 2,
the valve connected to the actuator closes; instead, if the phase is on terminal 3, the valve opens
(no contemporaneous phase on terminal 2and 3is allowed).
Connect the neutral on terminal 1 both for 2-POINT and 3-POINT versions.
With the 2-POINT connection, it is possible to activate multiple actuators with the same control devi-
ce (thermostat, relay, etc.) With the 3-POINT connection, it is possible to activate only one actuator
with a control device and to make in-between settings in order to make a modulation, provided it is
used with a suitable control device.

ANTI-CONDENSING HEATER
The anti-condensing heater prevents the risk of condensation inside the actuator.
To activate the heating effect of the resistance, connect the two resistance wires using suitable
faston connectors.
The supply voltage must be equal to the one indicated on the tag.
