HANDLING
Before commencement of lifting ensure that normal equipment safety checks have
been carried out and the lift/deposit areas are clear of site personnel and
traffic. Obtain the weight of the unit from the rating plate and lift using
“spreaders” as shown (Figure 1).
MECHANICAL INSTALLATION
Installation must be carried out by competent personnel in accordance with the
appropriate authority and conforming to all statutory and governing
regulations e.g., I.E.E., CIBSE, COHSE etc. Units are suitable for internal
use unless it has an optional outdoor cover (Section 5.0 for outdoor weather
cover details). Prior to installation the impeller should be rotated by hand
to check for smooth rotation and that no transit damage has occurred. It is
advisable to fit flexible connectors on either side of the fan unless there is
an open-ended inlet or discharge, and the fans should be supported on A/V
mounts (Figures 2 & 3).
The A/V mounts should be “levelled off” for satisfactory running and the flexible connectors installed maintaining the line of the ductwork with minimal crimping. A range of ancillaries including guards and silencers are available from Nuaire.
ECOSMART CONTROL INSTALLATION
(OPTIONAL)
The Ecosmart Control Box is a separate item, packed individually.
The controller must be fitted indoors (an optional outdoor cover can be
purchased) and away from moisture ingress.
The operating range is -10 to +35°C with up to 85% relative humidity. The
controller must be fitted to a vertical vibration free wall with appropriate
fasteners and for ease of installation the cover should be removed, and the
casing separated from the base. If cooling fans are fitted, they should be
disconnected while installation takes place.
The cable connecting the Ecosmart control to the fan must be a screened power
cable, max length 30m. It should be earthed at
both ends using the special cable glands supplied (Details of wiring
connections are shown on pages 2 & 4).
Inverter Speed Control – An Inverter is used to provide speed control. When
the fan is isolated, allow 5 minutes for the capacitors in the inverter to
discharge before commencing any work on the unit.

Three Phase with Ecosmart Control
Installation Manual
Ecosmart Control Connections
Control Connections
Net – the 4 IDC plug-in connectors are provided for the connection of
compatible sensors, manual controls and for linking the fans together under a
common control. If more than 4 connections are required, the junction box
(product code ES-JB) should be used (see data cable installation).
Switch Live (SL) Terminal – A signal of 100-230V AC will activate the fan
(required at each control).
A signal from an isolating transformer will produce an unpredictable result
and is not recommended.
Damper Connections
OP – 230V 50Hz 1A max supply to open the damper
CL – 230V 50Hz 1A max supply to close the damper
N – Neutral supply to damper
RET – 230V AC return signal from the damper limit switch indicates the
damper has reached its operating position. If the return signal is not
present, the fan will wait for 1 minute before starting.
If a damper is not fitted, connect a link wire from OP to RET. This will
cancel the delay.
Where units are supplied in modular sections, it will be necessary to install
and connect mains wiring between controls and devices such as motorised
dampers, it may also be necessary to install and connect mains wiring between
sensors and actuators.
Depending on final damper location, extension of the cable looms may be
required.
Volt Free Relay Contacts
The volt free contacts are not fused. If these are used to power any external
equipment, the installer must provide adequate fusing or other protections.
Volt free relay contacts are rated at 5A resistive, 0.5A inductive.
Run Connections – Contacts closed when the fan is running
Fault Connections – No Fault = Contacts are closed
Fault – Contacts are opened
Heat Demand – Contacts closed when heating is selected.
Data Cable Connection
A 4-core SELV data cable is used to connect devices.
Do not run data cable in the same conduit as the mains cables and ensure there
is a 50mm separation between the data cable and other cables. The maximum
cable run between any two devices is 300m when it is installed in accordance
with the instructions.
Please note that the total data cable length used in any system must be less
than 1000m. Keep the number of cable joints to a minimum to ensure the best
data transmission efficiency between devices.
Maximum Number of Devices
The maximum number of devices (including fans) that can be connected together
via the cable is 32, irrespective of their functions.
Other Low Voltage Cables
Follow the basic principle in Section 6.2.4. Keep the cable run as short as
possible, less than 50 metres. Use screened cable if cable length is more than
2m.
Ecomsart Commissioning Board
Using Test Button (ES Control Only)
The test button allows the individual blowers within the unit to be checked
for its operation. If the fan is running already, press the button once to
stop the fan, press again to switch on the fan. The fan will return to normal
operation after 30 seconds.
LED Indication
- PWR GREEN: Power on & OK.
- Standby LED on when fan is not running.
- Fan 1 GREEN: Fan 1 is running, RED: Fan 1 faulty.
- Fan 2 GREEN: Fan 2 is running, RED: Fan 2 faulty.
- **Heating*** GREEN: Heating selected RED: Heating faulty.
- **Cooling*** Not applicable. See note.
- Fault LED on when a fault is present on unit.
- **Frost*** Not applicable. See note.
- TX LED on when the controller is transmitting data
- RX LED on when the controller is receiving data.
*The control panel is common to all the Ecosmart products and will have indicators for functions that are not available in this particular fan. However these indicators will not be illuminated.
Maximum Airflow
- Ensure the power supply is switched off and that a link wire is connected from the supply L to the SL terminal. Unplug all items connected to the ‘Net‘ connectors.
- Switch on the power supply.
- Wait for the fan to complete its self-test operation.
Measure the airflow using standard commissioning instruments at a suitable point in the ductwork. If adjustment is required, rotate the pot marked ‘MAX’ to obtain the desired airflow.
Minimum Airflow (Trickle)
- Repeat the same procedure as for maximum airflow above but without the link wire between supply L and SL terminal. Ensure the trickle switch is in the ‘ON’ position. Adjustment must be made on the pot marked ‘Min’
The minimum setting (20% of maximum air flow) must be below the maximum setting; otherwise minimum setting will be automatically set to be the same as the maximum.
Trickle Ventilation
Slide the ‘trickle’ switch 0 = Off, 1 = On. With ’trickle’ on and power to
unit, the fan will run at minimum speed until the switch live signal activates
it to boost.
Overrun Time
A switched live of 100-230V at terminal SL will activate the fan.
When the switched live signal is removed the fan will overrun for period set
by the dial ‘SL run on’ – adjust the desired overrun time between 1-60 minutes
by rotating clockwise.
BMS Input Signals
The system’s response to a 0-10V DC BMS signal is given in the following
table. The BMS signal will override any sensors and user control connected in
the system. The voltage tolerance is +/- 125mV and is measured at the fans
terminal.
