ES-ISCT
Installation Manual
2.0 INTRODUCTION
The Ecosmart Energy Saving Speed Control is designed to control
selected Nuaire fans and to match the range of integrated
Ecosmart control systems.
The control is only available for three phase electrical supply.
The case material is of Aluzinc corrosion resistant steel, incorporates a
frequency inverter, Ecosmart control board and is directly compatible
with the Ecosmart range of user controls, time clocks, ‘stats and
sensors.
3.0 DELIVERY & HANDLING
All equipment is inspected prior to despatch and leaves the factory in
good condition. Upon receipt of the equipment an inspection should be
made and any damage indicated on the delivery note.
Particulars of damage and/or incomplete delivery should be endorsed
by the driver delivering the goods before offloading by the purchaser.
No responsibility will be accepted for damage sustained during the
offloading from the vehicle or on the site thereafter. All claims for
damage and/or incomplete delivery must be reported to Nuaire within
two days of receipt of the equipment.
The weight of the unit modules and palletised items are displayed
on the packaging. Some of the modules have an uneven weight
distribution, and this will be indicated by labelling where appropriate.
Offloading and positioning of the equipment is the responsibility of
the purchaser. Items should only be lifted by competent personnel
following appropriate risk assessment.
Always handle with care to avoid damage and distortion, and where
lifting slings are employed use spreaders to ensure slings do not come
into contact with the unit case, or control pack.

Typical Lifting Methods
4.0 DIMENSIONS (mm) & WEIGHTS (kg)
Control sizes are selected by matching the unit full load current with
the control code i.e. control code ES-ISCT8.8A is suitable for a fan with
a maximum full load current of 8.8A.
The Inverter overload is pre-set at the rating plate value, if a lower
setting is required fit an appropriately sized overload relay to the output
contactor and adjust accordingly.

5.0 INSTALLATION
Installation must be completed by competent persons, in accordance
with good industry practice and should conform to all governing and
statutory bodies i.e. IEE, CIBSE, etc.
The ES-ISCT is designed to be installed indoors
, away from any water
spray or steam generating source. Fix or mount in upright position to a
secure vibration free vertical surface (Figure 2). Ensure the ventilation
grilles are free of obstruction. Minimum distance of 50mm between
grilles and any side obstruction. Minimum distance of 100mm between
grilles and any top obstruction.
If the unit is installed outdoors,
the matching size weathering cover ES-ISCT-WP must be used to
provide weather protection.
The operating range is -10°C to 40°C, up to 85% relative humidity
(non-condensing). Installation in unventilated loft is not
recommended.
Ensure that the unit is electrically isolated from the mains supply
before commencing work. When the fan is isolated, allow 5
minutes for the capacitors in the inverter to discharge before
commencing any work on the unit.
Motors of 4kW and above must be connected to Delta ∆.
The screening of the power cable must be continuous. Bridge any
breaks (e.g. at local isolators) using braided earthing cable. Ensure
the screening is earthed at both ends.
5.1 Mechanical Installation
For ease of installation, remove the front cover and disconnect any
cooling fans fitted. Remove the control casing from the base, offer the
base to the wall (or mark from the drill pattern).
Drill and fix the base to the wall using appropriate fasteners. It may be
easier to connect the field wiring at this stage. Reassemble the case
ensuring that cooling fans are reconnected.
