Installation manual
Read this manual attentively before installation. Do not
throw it away. Keep it in your files for future reference.
Improper installation or attachment of equipment or
accessories could result in electric shock, short-circuit,
leaks, fire or other damage to the equipment. Be sure only
to use accessories made by Daikin that are specifically
designed for the use with the equipment and have them
installed by a professional.
If unsure of installation procedures or use, always contact
your 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.
The English text is the original instruction. Other languages are
translations of the original instruction.
This option kit needs to be used in combination with an EKRP1C11
kit and a FWF or FWC fan coil unit.
The units are equipped with a water inlet and water outlet for
connection to a water circuit. This circuit must be provided by a
licensed technician and must comply with all relevant European and
national regulations.

CONNECTION OF THE FAN COIL UNIT TO FIELD
PIPING BY USE OF THE 2-WAY/3-WAY VALVE
Refer to the installation manual of the fan coil unit for details on
installing the fan coil unit.
Be careful not to deform the unit piping by using excessive
force when connecting the piping. Deformation of the
piping can cause malfunction of the unit.
If air, moisture or dust gets in the water circuit, problems may occur.
Therefore, always take into account the following when connecting
the water circuit:
■ Use clean pipes only.
■ Hold the pipe end downwards when removing burrs.
■ Cover the pipe end when inserting it through a wall so that no
dust and dirt enter.
■ Use a good thread sealant for the sealing of the connections.
The sealing must be able to withstand the pressures and
temperatures of the system.
■ When using non-brass metallic piping, make sure to insulate
both materials from each other to prevent galvanic corrosion.
■ Because brass is a soft material, use appropriate tooling for
connecting the water circuit. Inappropriate tooling will cause
damage to the pipes.
■ 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.
■ Never use Zn-coated parts in the water circuit.
Excessive corrosion of these parts may occur as
copper piping is used in the unit's internal water
circuit.
■ The equipment is not intended for use in a potentially
explosive atmosphere.

Pay attention to the mark on the 3-way valve
body.
The long arrow must point inside the inlet water piping of
the fan coil unit.
In case 2 valves are installed on the same fan coil unit
(4 pipe model), use the same method described above to
install the second valve.
The complete water circuit, inclusive all piping, must be
insulated to prevent condensation and reduction of the capacity
(minimum thickness: 10 mm).
If the temperature is higher than 30° and the relative humidity is
higher than 80%, the thickness of the sealing materials should
be at least 20 mm in order to avoid condensation on the surface
of the sealing.
4 Seal the valve and piping connections.
1 Add the "insulation for valve" (1) around the valve and the
sealing of the unit piping and the field piping.
2 Close the sealing off with the insulation tape (2).
