1.0 Introduction

2.0 Warnings & Safety Measures

This heater/cooler fan convector is designed for use on
central heating systems or heating and cooling systems in
homes and commercial environments. Models are available
with 2 and 4-pipe connections.

The control system provides thermostatic room temperature and
fan speed control, and allows operation on a stand alone basis,
or by integration into building management systems.

The unit is fitted with a washable air filter that can be easily
removed for cleaning.

A range of accessories are available for this product including
control valves and condensate pumps for cooling installations.

l Please carefully follow the instructions and guidelines

contained in this manual during installation. Always perform
each step in sequence.

l Inspect this product for concealed shipping damage prior to

installation. If items are damaged or missing please contact
your supplier.

l This fan convector must be installed by qualified tradespeople.

l Do not install this fan convector in areas where excessive

dust exists.

l The manufacturer accepts no liability for damage or injury

caused by failure to adhere strictly to the safety precautions
and instructions contained in this manual, or by negligence
during the installation of the product and any accessories
described in this manual.

l 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

This manual should be read carefully prior to installation and retained for future reference.

This fan convector can be fitted on a series loop with mono-flo or venturi tees, on a two pipe system, or
on a stand alone zone.

This unit MUST NOT be installed in a bathroom or other high humidity area.

This appliance must be grounded.

DO NOT cover or obstruct the air inlet or outlet grille.

Disconnect from the power supply before carrying out any maintenance work.

This heater/cooler fan convector is designed for wall mounted
installation.

For optimum fan convector performance the system must be
capable of providing sufficient flow of water through the heat
exchanger at the correct temperature. This means that:

1. Pipework should be designed and installed to guarantee
sufficient water flow through the unit. Refer to section 3 on
page 4 for recommended pipe sizes.

2. This unit is not suitable for series loop pipe systems.

3. Optimum performance will require effective balancing of the

whole system. Each emitter on the circuit should be checked
and valves adjusted so that the required water flow rate
through each unit is achieved.

4. Where the unit is fitted on to a system with other emitters a
separate circuit for the fan convector should be considered
in order to provide sufficient flow through the unit.

5. The system water must be above 90°F for heating mode and
below 59°F in cooling mode.

6. This unit must not be used to replace a radiator in an existing
heating system unless an adequate flow of water through the
unit can be guaranteed.

Note: Pressure independent balancing and control valve kits
are available for this product as an accessory. The valve
kits can simplify system design by eliminating the possible
need for larger balancing valves elsewhere in the system, and
will maintain the flow in the unit to the required levels. See
accessories section for more details.

NB: Pipes should be sized using flow rate and pressure losses.

4.0 Unit Selection/Sizing

Heating output performance data is given in the technical data
section of this manual (see page 15). Outputs are shown for the
three fan speeds, however, it is important to size the unit to
match the calculated heat loss requirements of the room with
the unit operating on the normal fan speed. The higher fan
speeds are used in Comfort mode when the room temperature
is significantly lower than the preset temperature.

Note: It is also possible to electronically remove the highest fan
speed from the functionality of this unit via the control system
(see page 20). This may be advantageous on low temperature
systems to prevent cool air being blown into the room on the
highest setting.

When establishing the temperature difference,

i.e. entering

water to room temperature difference, allowance should be
made for the temperature drop in the system. It is the water
temperature at the unit that dictates the output.

5.0 Location

This unit may be fitted to any convenient wall at a height from
the floor level that suits the application, providing an unimpeded
flow of air into the area to be heated/cooled.

For cooling applications, the need for disposal of condensate
may influence the position of the unit.

8.0 Water Connection

Before making the pipework connections refer to section 3.0 for advice on System Design.

Connect the unit to the supply and return pipes. Pipework can
be routed from the floor or through the wall at the back of the
unit. (See options below). Connections are 3/4"bsp.

Connection directly onto the heat exchanger should be made
using straight connectors so that the pipework can more easily
be routed inside the unit.

For heating only applications the condensate collector mounted
on the chassis below the heat exchanger connections is not

needed and can be removed by unscrewing the two bracket
fixing screws. Removal of this component will aid pipework
fitting when the pipes are routed up from the floor.

For applications involving cooling, the pipework must be routed
to avoid the condensate collector. Connection to the heat
exchanger should be made using straight connectors so that
the pipework can more easily be routed past the condensate
collector.

Pipe Routing Options

2-pipe connection

(The same options are possible for 4-pipe connection)

Note 1: The supply pipe should be connected to the bottom
connection of the heat exchanger.

Note 2: Isolating valves are not supplied with this unit, but
should be fitted in case of future service requirements.
The type and size of valves and their location should be suitable
for the application. Valves should be selected in accordance with
system temperature and pressure requirements whilst taking into
account pressure drop characteristics.

Note 3: External pipework carrying chilled water must be
insulated. Use a suitable sealant as necessary to ensure that
condensate does not spill or leak. Once connection to the
system flow and return pipes is made, any exposed internal
pipework and isolating valves must also be insulated.

with this unit is not the result of system controls being

incorrectly set, that there is no electrical supply to the unit or
that the unit is incorrectly set.

Possible Installation Faults

Poor heating or cooling performance from this unit could be the
result of one or more of the following factors which should have
been taken into consideration at the installation stage.

l Unit incorrectly sized against the room heat loss.

l Lack of water flow - Incorrect pipe size to unit

- Valves not fully open

- System incorrectly balanced

- Pump set too low

l Boiler or heat pump controls set too low.
