2.0 Installation
For the correct installation of this unit it is essential that
fixing is carried out in such a way that it is suitable for
intended use and predictable misuse. A number of elements
need to be taken into consideration including the fixing method
used to secure it to the wall, the type and condition of the wall
itself, and any additional potential forces or weights that may
happen to be applied to the unit, prior to finalising installation.
Before proceeding with the installation, remove the carton lid,
unpack the content and check against the items shown in FIG 1.
Also check contents for concealed shipping damage.

3.0 Water Connection

Note: Before making the pipe-work connections ensure pipes
have been sized correctly in line with the flow rate and pressure
loss requirements .
l Pipes should be sized based on flow rates and pressure loss
requirements.
l Connect to heat exchanger - G
l Care should be taken when connecting the flow and return
pipes to the iVECTOR, see FIG 3 for information also a range
of routing options can be found in FIG 4.
l Isolation valves are not supplied with this unit however it is
advised they are fitted in case of future service requirements.

4.0 Electrical Connection

WARNING: All iVECTOR models must be earthed.
l The electrical installation must comply with local or
national wiring regulations and should be carried out by a
qualified electrician.
l This unit is supplied with factory fitted test leads. Remove
these and discard.
l A fused electrical spur with a maximum 3A fuse and a switch
having 3mm separation on all poles must be provided in an
easily accessible position adjacent to the unit.
l Electrical cable entry to the unit should be made through the
underside of the unit, into the control box on the right hand
side using the cable gland provided. The supply cord must
be 0.75mm² only.
l Connect the live and neutral and earth to the wiring block
terminal connections.
l Follow stages a-c shown in FIG 8 to access the control panel.
Product wiring diagrams are shown in FIG 10.
l When using a valve kit with an actuator, it is possible to
remove the terminals from the power board for easy
installation, this is shown in FIG 8d. The cable should also be
routed via the diagram in FIG 8e.
For cooling applications an external sensor is required, see FIG 8f - 8i

Check the location where the product is to be installed, the wall
surface must be flat and clearances shown in FIG 2 must be
available. If iVECTOR is fitted to a stud wall, there may be an
adverse effect on the sound levels especially with the higher fan
speeds. If the iVECTOR is to be used for cooling applications
then the disposal of the condensate must be considered.
For types BC and BN follow stages a-f from FIG 5 and for types
FC and FN follow stages a-c then g-i to show how to fit product
to the wall.
Note: Do not fit outer casing until water (Section 3) and
electrical connections (Section 4) have been completed.
Type BN - Bottom inlet/no controls
Type BC - Bottom inlet/intergrated controls
Type FN - Front inlet/no controls
Type FC - Front inlet/intergrated controls
l If the iVECTOR is to be used for cooling applications with
chilled water then the pipe-work supplying the chilled water
should be insulated. Condensate will form at the coil and fall
into the condensate collector, see FIG 6. Provision must be
made for condensate disposal in accordance with any local
regulations.
l Fill and vent the system, open all valves fully and vent from
the heat exchanger, see FIG 7 then check for leaks.
l Heating and cooling pipework under the iVECTOR must be
insulated.
l When using an external air sensor for cooling applications the
existing sensor must be removed and the new sensor installed
in its place as shown in FIG 8f-8g, the external sensor should
be positioned as shown in FIG 8h-8i.
l Units with controls (type BC/FC) can be used to control units
with no controls (type BN/FN) by taking the 0-10V output
from the type BC/FC to the type BN/FN in accordance with
wiring diagram 10c. Interconnecting wires should be 22AWG,
60°C in rating.
l An external room thermostat can be used to control No
Control (type BN/FN) units. The thermostat must have a
0-10V output.
l It is possible to control up to 5 no controls units (type BN/FN)
from a unit with controls (type BC/FC) or up to 6 no control
units (type BN/FN) from an external controller (supplied by
others). See wiring diagram 10a 'B' for the output signal from
the controls unit and 10b 'D' for the input signal from the
controls unit to the no controls unit, this is also the same input
signal for the external controller as shown in 10b 'D'.
l Multiple valves (up to 6) can be controlled from a type BC/FC
as shown in FIG 10e.
