Introduction
Units are rectangular in section and have circular rigid spigots
at each end. Four matching mounting feet are supplied with the
unit.
Full size access panels are fitted to the top and bottom faces.
These panels are fully detachable for inspection purposes.
The models are coded as follows:
EST (Internal Duct Mounted) in line unit.
Handling
Handle the units carefully to avoid damage and distortion.
If mechanical aids are used to lift the unit, spreaders should be
employed and positioned so as to prevent the slings, webbing
etc. making contact with the casing.
Installation
The installation must be carried out by competent personnel
in accordance with the appropriate authority and conforming
to all statutory and governing regulations.
The units can be mounted in any attitude except vertical with
the outlet facing down, or inverted i.e. upside down as in these
attitudes the shutters will not operate.
The units are supplied for installation into In-line ductwork
(internal) applications. The mounting feet can be employed in
surface or suspended applications.
Units should always be positioned with sufficient space to
allow removal of the access covers and subsequent removal
of fan and motor assemblies etc.
Ductwork connections must be airtight to prevent loss of
performance. The method of mounting used is the total
responsibility of the installer. The unit has an external case side
mounted control module/terminal box and is supplied ready for
connection into the electrical supply. If necessary, the module
can be located on the other side of the unit (fixings by others).
Rigid Mounting
Note, the unit case has captive M8 nuts which can be used
after removing the M8 ‘plugging’ screws.
On Resilient Mountings
Suspension rods / fixing screws are not supplied. Note that the
large round washers included in the resilient mounting kits are
for fitting above or below the resilient mounting as required to
safeguard the installation against break-up of, or damage to,
a mounting. In the event of a resilient mounting failure the
washer will support the weight of the unit.
Suspended from ceiling
Large washers should be fitted BELOW the resilient mounts.
