INSTALLATION
General
Before removing any packaging, check the identity of
the fan coil unit against the stencil reference marked
on the access panel. Packaging should be retained to
protect the fan coil unit from damage by other works
after installation.
Fitting
1.
Prepare drop rods to accept the fan coil. M6, M8
or M10 drop rods are recommended, with
appropriate washers. Refer to diagram 2 for
positions of fixings.
2.
Suspend the fan coil unit and ensure it is level
in both directions. Use a spirit level
casing. (The drip tray is graded internally to
ensure drainage of condensate).
3.
Connect ductwork to the fan coil unit. Flexible
duct connections are recommended where
sheet metal ductwork is used. Do not suspend
any ductwork from the fan coil unit alone. Refer
to diagram 4 for spigot positions.
4.
Connect pipework as shown in Diagram 5.
5.
Connect a suitable drain to the drip tray.
6.
Connect electrical supply and control
accessories as shown in wiring diagrams
enclosed with the fan coil unit.
7.
After filling the hot and chilled water systems,
check for leaks (refer to Commissioning).
8.
Ensure condensate pump is installed in
accordance with the manufacturer's
requirements and see Diagrams 3a and 3b

The coil is a dual-purpose coil with OD15mm
copper tube tails at 40mm centres between flow
and return connections. Always observe the
correct direction of flow. (see Diagram 5)
Local isolating and regulating valves are
recommended, as well as strainers to filter out
foreign matter in the water.
The installer must provide any fittings to
connect pipework to fitted 2 or 4 port valves.
The drip tray has an OD22mm tube connection,
suitable for a compression fitting or similar, to
be supplied by the installer.
The electrical connections box is located on the
side of the fan coil unit, and incorporates a
hinged access door, fastened with a
self-tapping screw.
Connect a 230V/1ph/50Hz supply to the flying
lead fitted to the electrical connections box.
Fit any remote accessories in their appropriate
locations and connect terminal block inside the
electrical connections box.
Refer to the wiring diagram enclosed with the
fan coil unit for specific wiring details.
All wiring should comply with IEE regulations
(BS 7671) and local bye-laws.
