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.
