3.0 Installation
3.1 Installing the unit
1. Check that all the components have
been delivered, as identified in the
delivery note. Notify the supplier of any
errors or omissions immediately.
2. Check the diagrammatic ducting layout
drawing to ensure that the proposed duct
routes, fan unit and air terminal locations
can be accommodated. If in doubt, refer
to the Technical Support Department.
3. The unit is designed to be mounted
horizontally. After noting the positions of
the electrical connector, duct spigots and
suitable installation site for the unit. The
drainage connection for the unit, choose a
most desirable location for the unit is
normally within the ceiling void.
4. Never locate the unit above a sleeping
area. The most suitable position is
normally above the landing or bathroom.
The selected site must allow adequate
space around the unit for the removal of
the cover and heat exchanger for
maintenance and servicing purposes.
5. The unit is attached to the ceiling slab
with suitable fixings at four positions.
Drainage slope is provided by the set of
the fixing brackets
6. The unit must be positioned so that the
condensate outlet will accommodate a
trap (Hep vO waste valve) and the
condensate conveyed properly with a
continuous gradient to a suitable
positioned down pipe.
7. Connect the drainage system as
appropriate using PVC pipe work, joined
using PVC cement to ensure waterproof
joints. Fit a flexible tube adjacent to the
unit to allow the cover to be moved clear
during maintenance.
Also note that a blocked condensate
outlet pipe due to insufficient pipe
gradient will quickly lead to water damage
