NOTE: The Ecosmart Control Box is a seperate item,
packed individually.
Warning - 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.
Introduction
The units shall be manufactured from a highly rigid
pentapost framework with 25mm double skinned infill
panels. The panels shall contain inert high density infill. Panel
materials are heavy gauge Aluzinc corrosion resistant steel.
The units shall provide exceptional thermal and acoustic
insertion. The very low breakout noise level through the unit
casing must not be exceeded.
The general construction is to class A leakage.
The fan impeller and motor shall be selected to provide the
most energy efficient solution conforming to part L
regulations and shall be direct drive with EFF2 high
efficiency motors to BS5000 as standard.
The fan impeller shall be a high efficiency backward curved
centrifugal design, manufactured in galvanised steel.
Galvanised steel.
NOTE: Maximum ambient operating
temperature 50 Degree C.
1.0 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.
Note: the weight of the unit from the rating plate and lift
using “spreaders” as shown in (figure 1.)
2.0 Fan 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 a optional
outdoor cover. (Please refer to section 3.0 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 and 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.
2.1 Ecosmart Control Installation
The controller must be fitted indoors (an optional outdoor
cover can be purchased) and away from moisture ingress.
The operating range is - 10
o
to 35
o
C up to 85% relative
humidity.
The controller must be fitted to a vertical vibration free wall
with appropriate fastners 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 and 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).
