1 Introduction

Thank you for purchasing this DAIKIN fan coil unit.

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 installer for a list of related products.

either hot or cold water to the unit.

■ FWF02-03-04-05B7FV1B

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

Precautions for installation

The installer should install and connect your fan coil unit as described in the installation
manual. Please note that the installer can only install your fan coil unit:

■ in a concealed ceiling,

■ in perfect condition.

Precautions before operating

Only operate your fan coil unit after it has been installed by a licensed installer. Verify that
the installation has been completed by checking that the “Annex: Handover of the installation

to the user” on page 11 has been filled in completely.

Precautions for operating

Only operate a fan coil unit if you are fully alert and aware.

Fan coil units are not intended for use by persons with reduced physical, sensory or mental
capabilities or those who have not used the fan coil unit before, including children. When
these persons want to use the fan coil unit, the person responsible for their safety must
supervise them or instruct them in the use of the fan coil unit.

3 Tips for optimal operation

■ Adjust the room temperature properly for a comfortable environment. Avoid excessive
heating or cooling. Notice that it may take some time for the room temperature to reach
the set temperature. Consider using the timer setting options.

■ Prevent direct sunlight from entering a room during cooling operation by using curtains
or blinds.

■ Ventilate the room regularly. Using the unit for long periods of time requires attentive
ventilation of the room.

■ Keep doors and windows closed when the unit is in operation. If the doors and windows
remain open, air will flow out and decrease the effect of cooling and heating.

■ Never place objects near the air inlet and the air outlet of the unit. It may reduce the
effectiveness or cause the unit to stop.

■ Turn off the main power supply switch when not using the fan coil unit for long periods
of time. Electricity is consumed so long as the switch is on. Turn off the main power
supply switch in order to save energy.

■ Fully use the function of air flow direction adjustment if available. As cold air gathers on
the floor and warm air gathers against the ceiling, it is recommended to set the air flow
direction during cooling operation parallel to the ceiling and to set it downwards during
heating operation. Be sure that you do not direct air flow on to the inhabitants of the
room.
