IntroductionIntroduction

1 Introduction

Introduction

1.1. About fan coil units

A fan coil unit provides heating and/or 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:

2

Q a fan,
Q a heat exchanger.

2

The heat exchanger receives hot or cold water from a heating or
cooling source.
DAIKIN offers a wide range of fan coil units for both concealed and

2

exposed applications. Contact your DAIKIN dealer for a list of related
products.

Introduction

Cassette
C: 3x3

T: 2-pipe
F: 4-pipe

2-pipe fan coil units have a single-circuit heat exchanger. The
device can be used for either cooling or heating.

4-pipe fan coil units have a double-circuit heat exchanger. The
units can be connected to both cooling and heating systems. Use
this type if you have a separate source for cooling and for
heating.

1.3. About this document

This document is an installation manual. It is intended for the installer
of this product. It describes the procedures for installing,
commissioning and maintaining the unit, and it will provide help if

Precautions for installation

1.3.1. Meaning of warnings and symbols

Warnings in this manual are classified according to their severity and
probability of happening.

Danger: Indicates an imminently hazardous situation
which, if not avoided, will result in death or serious injury.

Warning: Indicates a potentially hazardous situation which,
if not avoided, could result in death or serious injury.

Caution: Indicates a potentially hazardous situation which,
if not avoided, may result in minor or moderate injury.

Notice: Indicates situations that may result in damage to
equipment or property.

Information: This symbol identifies useful information, but
no hazardous situation warnings.

Some types of danger are represented by special symbols:

Electric current

Danger of burning or scalding

Precautions for installationPrecautions for installation

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, short­circuit, 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.

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.

3.2. Verify the appropriate installation location

When selecting the installation location, take into account the
instructions as mentioned in the following paragraphs of this chapter.
Select an installation location where the following conditions are
fulfilled:

Q the space around the unit is adequate for maintenance and

servicing. See figure 2: “Space required for installation”.

Q the space around the unit allows sufficient air circulation and air

distribution. See figure 2: “Space required for installation”.

Q the unit may be installed on ceilings up to 4.2 m. However, it

becomes necessary to make field settings using the remote
controller when installing the unit at a height over 3.2 m.
Install the unit where the height of the decoration panel is more
than 2.5 m to avoid accidental touching.

Q the air passage is not blocked.
Q the condensate water can be properly drained.
Q the installation location is frost-free.
Q the unit can be installed horizontally.
Q the unit must be installed as far away as possible from

fluorescent lights or other sources that possibly interfere with the
signal of wireless remote controllers.

See figure 2: “Space required for installation”

Information

Leave 200 mm or more space where marked with *, on
sides where the air outlet is closed.

Refer to figure 2: “Space required for installation”.

Information

The equipment is not intended for use in a potentially
explosive atmosphere.

Prepare the installation of the fan coil unit

3.3. Prepare the installation space

Q 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 5.

Q 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 installation of the fan coil unit

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.

Notice

The unit is only to be used in a closed water system.
Application in an open water circuit can lead to excessive
corrosion of the water piping.

Before performing the water piping work, check the following points:

Q the maximum water pressure is 10 bar,
Q the minimum water temperature is 5°C,
Q the maximum water temperature is 50°C (2-pipe fan coil units)

and 70°C (4-pipe fan coil units),
Q be sure to install components in the field piping that can withstand

the water pressure and temperature,
Q provide adequate safeguards in the water circuit to be sure that

the water pressure will never exceed the maximum allowable

working pressure,
Q provide a proper drain for the pressure relief valve (if installed) to

avoid any water coming into contact with electrical parts,
Q be sure that the water flow rates are according to the table below,

speed (l/min.)

FWC06-09B7FV1B 5.4 36 cooling coil +

Table 3.1: Maximum and minimum water flow

Q provide shut-off valves at the unit so that normal servicing can be

accomplished without draining the system,
Q provide drain taps at all low points of the system to permit

complete drainage of the circuit during maintenance or service to

the unit,
Q provide air purge valves at all high points of the system. The

valves shall be located at points which are easily accessible for

servicing. A manual air purge valve is mounted onto the unit,
Q always use materials which are compatible with the water and a

maximum of 40% volume glycol,
Q select piping diameter in relation to required water flow and

available ESP (External Static Pressure) of the system pump.
