Installation Operation & Maintenance Instructions

201-2001 heat interface unit
1
These instructions must be read and understood
before installing and maintaining the HIU.
CAUTION! FAILURE TO FOLLOW THESE
INSTRUCTIONS COULD RESULT IN A SAFETY
HAZARD!
1The device must be installed, commissioned and
maintained by qualified technical personnel in accordance
with national regulations and/or relevant local
requirements.
2If the device is not installed, commissioned and maintained
correctly in accordance with the instructions provided in
this manual, it may not work correctly and may endanger
the user.
3Flush the pipework thoroughly before installing the HIU to
remove any particles, rust, incrustations, limescale, welding
slag and any other contaminants.
The water circuits must be clean and free from debris.
4Make sure that all connection fittings are watertight.
5When connecting water pipes, make sure that threaded
connections are not mechanically overstressed. Over time
this may result in breakage, causing water damage and/or
personal in ury.
6Water temperatures higher than 50˚C may cause severe
burns. When installing, commissioning and maintaining the
device, take the necessary precautions so that these
temperatures will not be hazardous for people.
7In the case of particularly hard or impure water, there must
be suitable provision for filtering and treating the water
before it enters the device, in accordance with current
legislation. Failure to do so may result the HIU becoming
damaged or working incorrectly.
8Any use of the HIU other than it’s intended use is
prohibited
9Any coupling of the device with other system components
must be made while taking the operational characteristics
of both units into consideration.
10An incorrect coupling could compromise the operation of
the device and/or system.
11 If the system is prone to ‘water hammer’ a water hammer
arrester must be installed.
12If hot water recirculation is present or a non-return valve is
installed in the cold water inlet, provision must be made to
accommodate water expansion by fitting an expansion
vessel.

Safety Instructions
NOTE: Risk of electric shock. Live parts. Shut off the electric
supply before opening the HIU cover.
1During installation and maintenance operations, always
avoid direct contact with live or potentially hazardous parts.
2The device must not be exposed to water drops or humidity,
direct sunlight, the elements, heat sources or high intensity
electromagnetic fields.
This device cannot be used in areas at risk of explosion or
fire.
3The device must be connected to an independent bipolar
switch. If work has to be done on the device, switch off the
electric supply first. Do not use devices with automatic or
time reset, or which may be reset accidentally.
4Use suitable automatic protection devices in compliance
with current legislation.
5The device must always be earthed before it is connected to
the electric supply. If the device has to be removed, always
disconnect the earth connection after disconnecting the
electric supply. Check that the earth connection has been
made to the highest of standards under current legislation.
6Electrical installation only be carried out by a qualified
technician, in accordance with current requirements.

Hydraulic connections
The whole system should be thoroughly flushed to remove
any debris that may be in the supply pipework to the HIU and
to the domestic hot water pipework in the apartment before
connecting the HIU.
Fix the HIU to the wall
N.B.: the wall anchors (not supplied) can only guarantee
effective support if inserted correctly (in accordance with
good technical practice) into walls built using solid or
semi-solid bricks. If working with walls built using perforated
bricks or blocks, mobile dividing panels or any masonry walls
other than those indicated, a preliminary static test must be
carried out on the support system.

Installation
The 201-2001 HIU is designed for installation in a sheltered
domestic environment (or similar), therefore cannot be installed
or used outdoors, i.e. in areas directly exposed to atmospheric
agents. Outdoor installation may cause malfunctioning and
hazards.
If the device is enclosed inside or between cabinets, sufficient
space must be provided for routine maintenance procedures. It is
recommended that electrical devices are NOT placed underneath
the HIU, as they may be damaged in the event of leakage from
any hydraulic component of connection.
If this advice is not heeded, the manufacturer cannot be held
responsible for any resulting damage.
In the event of a malfunction, fault or incorrect operation, the
device should be deactivated; contact a qualified technician for
assistance.
Preparation
After establishing the position where the HIU will be installed,
perform the following operations:
•Mark the holes required for securing the HIU to the wall.
•Mark the position of the water pipe connections.
Check the measurements again before installing pipework and
electrical cables.

Technical Specification - Actuator of 2-port Control Valve
Materials: - base and cover: PC G 10
Synchronous motor: Normally closed
Supply: 230 V - 50 Hz
Power consumption: 6.5 W; 7 VA
Opening time: 70 to 75 s
Closing time: 5 to 7 s
Microswitch contacts rating: 0.8A
Protection class: IP 40
Max. ambient temperature: 40˚C
Complies with Directive: 72/23/EC and
89/336/EC
Length of power cable: 95 cm
Operation
With the electrical supply off, the actuator keeps the valve in the
closed position.
When a temperature thermostat or other electrical device switches
the supply on, the actuator moves the disc in the valve into the open
position.
When the supply is turned off, the valve closes again due to the
action of a return spring.
Construction
Auxiliary microswitch
The actuator is fitted with a microswitch to operate devices such as,
for example, a circulating pump. The microswitch comes on when
the valve is 60% open.
Manual opening
The valve can be opened manually by moving
the lever to the lock open position. When the
power is restored the manual control is
automatically overridden.
Clip on actuator
A rapid clip-on system makes it easy to remove the actuator from
the body of the valve for maintenance or replacement operations.
Operation
The actuator is fitted with a special mechanism for gradual
movement of the valve disc which prevents udder and vibration due
to the inertia of the gear motor.
Removing the actuator
1 Set the lever on the side of the actuator to the open position (or
to manual opening).
2 Press the open button on the side of the actuator and remove
the actuator.
Fitting the actuator
1 Set the lever on the side of the actuator to the open position (or
manual opening).
2 Check that the actuator is correctly positioned with respect to
the valve as determined by the different dimensions of the
operating stem and the locking pin.
3 Press the open button fully down. Clip on the actuator and
release the button.
Technical Specification - Differential Pressure Control Valve
Medium: water, glycol solution
Max. percentage of glycol: 50%
Max. working pressure: 16 bar
Temperature range: -10 to 120˚C
Diaphragm max. differential pressure: 6 bar
∆p setting range: 50 to 300 mbar
5 to 30 kPa
Connections
Capillary tube connection size: G¹/
Tightening torque: 4 to 7 Nm
Length of capillary Ø3 mm 1.5 m
∆p indicator
The operation of setting the ∆p
differential regulating valve is
simplified by the presence of the
mobile indicator (1) and the
graduated scale (2) in mbar on the
valve knob.
Shutting off the flow and maintaining the ∆p setting
It is possible to isolate the circuit controlled by the differential
regulating valve.
The mechanism to stop the flow is built into the valve.
The circuit is shut off by inserting an
Allen wrench into the hole and
turning it fully clockwise.
This allows the flow to be shut-off for
system maintenance without having
to reset the valves after re-opening.

Locking/sealing the regulated position
On the knob and on the valve body
there are special holes that can be
used to seal the devices, once the
regulation operations have been
completed.
The application of sealing means
that, during any inspections, it can
be easily seen if the system has not
been tampered with.
