1 Introduction

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 fan,

■ a coil (heat exchanger).

The heat exchanger receives hot or cold water from a heating or cooling source. The fan
spreads the heat or coolness in order to condition the space.

DAIKIN offers a wide range of fan coil units for both concealed and exposed applications.
Contact your DAIKIN dealer for a list of related products.

2-pipe fan coil units have one supply and one return pipe. The supply pipe can supply
either hot or cold water to the unit.

■ FWC06-07-08-09B7FV1B

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

2 Precautions for installation

All instructions described in this manual shall be carried out by a licensed installer.

Install the unit according to the instructions in the included documentation and the manuals
of the additional equipment (e.g. controller). Improper installation could result in electric
shock, short-circuit, leaks, fire or other damage to the equipment.

Be sure to wear adequate personal protection equipment (protection gloves, safety glasses)
when performing installation, maintenance or service to the unit.

If not sure of installation procedures or operation of the unit, always contact your local
DAIKIN dealer for advice and information.

Danger: electric shock

Switch off all power supply before removing the control box cover or before making
any connections or touching electrical parts.

To avoid electric shock, be sure to disconnect the power supply 1 minute or more
before servicing the electrical parts. Even after 1 minute, always measure the voltage
at the terminals of main circuit capacitors or electrical parts and, before touching, be
sure that those voltages are 50 V DC or less.

2 Precautions for installation

Danger: high temperature

Do not touch the water piping or internal parts during and immediately after
operation. The piping and internal parts may be hot or cold depending on the working
condition of the unit.

Your hand may get burned or frostbitten if you touch the piping or internal parts. To
avoid injury, give the piping and internal parts time to return to normal temperature
or, if you must touch them, be sure to wear adequate protective gloves.
