About fan coil units

1.1 About fan coil units

A fan coil unit provides heating and cooling to individual spaces. It creates a comfortable
environment in both commercial and residential applications. Fan coil units are widely used
for the air conditioning of offices, hotels and houses.

The main components of fan coil units are:

■ a f

an,

■ a

coil (heat exchanger).

The heat exchanger receives hot or cold water
spreads the heat or coolness in order to condition the space.

WF02-03-04-05B7FV1B

4-pipe fan coil units have two supply pipes and two return pipes. This allows either hot
or

cold water to enter the unit which makes it possible to heat and cool different areas of

ilding at the same time. Use this type if you have a separate source for cooling and

3.3 Prepare the installation space

■ When preparing the installation space, use the paper pattern for installation which is
delivered with the unit. More information on how to prepare the ceiling opening can be
found in chapter “Prepare the ceiling opening” on page 11.

■ When

the conditions in the built-in space are exceeding 30°C and exceeding a relative
humidity of 80%, or when fresh air is inducted into the ceiling, an additional insulation
is required on the outside of the unit (minimum 10 mm thickness polyethylene foam).

Prepare the water piping work

3.4 Prepare the water piping work

The unit is equipped with a water inlet and water outlet for connection to a water circuit. The
water circuit must be provided by an installer and must comply with the applicable
legislation.

4.1 Unpack the unit

When receiving the unit, please check its state. Verify if any damage occurred during
transport. If the unit and/or packing are damaged at delivery, report this immediately to the
carrier’s claims agent.

Identify model and version of the unit from the indications stated on the carton packing.

Leave the unit inside its packing until you reach the installation site. Where unpacking is
un

avoidable, use a sling of soft material or protective plates together with a rope when lifting,

this to avoid damage or scratches to the unit.

Warning

Tear apart and throw away plastic packaging b
them. Children playing with plastic bags face danger of death by suffocation.

When unpacking the unit or when moving the unit after unpacking, be sure to lift the unit by

lding on to the hanger bracket without exerting any pressure on other parts.

malfunction due to electrical noise.

■ For th

delivered with the remote controller.

■ Keep wiring

in neat order so that wires do not obstruct other equipment or force the
control box cover to pop open. Make sure the cover closes tight. Incomplete connections
could result in overheating, and in the worst case, electric shock or fire.

Notice

Never connect the unit transmission wiring to the remote controller wiring. This
