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.

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 Vido is fitted to a stud wall, there may be an adverse
effect on the sound levels especially with the higher fan speeds. If
the Vido is to be used for cooling applications then the disposal of
the condensate must be considered.
Follow stages a-f from FIG 5 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.
Note:
Before making the pipe-work connections refer to the Vido
specifiers guide for advice on system design.
l
Pipes should be sized based on flow rates.
l
Connect using field supplied

inch fitting.
l
Care should be taken when connecting the flow and return
pipes to the Vido, 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.
l
If the Vido 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
Units with controls (type C) can be used to control units with no
controls (type N) by taking the 0-10V output from the
type C to the type N in accordance with wiring diagrams 10a
and 10b. Interconnecting wires should be 22AWG, 60°C
in rating.
l
An external room thermostat can be used to control No Control
(type N) units. The thermostat must have a 0-10V output.
l
It is possible to control up to 5 no controls units (type N)
from a unit with controls (type C) or up to 6 no control units
(type N) from an external controller (supplied by others). See
wiring diagram 10a ‘B’ for the output signal from the controls
unit and 10b ‘C’ 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 10c ‘C’.
WARNING: All Vido models must be earthed.
