• Air Handling Unit Connection • Heat pump2

1 Features

Air handlin Air Handlin Control box Heat pump • Wide range of Daikin units offers maximum application potential plus flexible control options.

• The system provides optimized air conditions such as fresh air and humidity control etc. and can be used in small warehouses, showrooms and offices.

• Control box and expansion valve kit are required for each combination plus an air handling unit.

• Both option kits are designed for indoor and outdoor installation and can be wall mounted.

• High flexibility in control possibilities thanks to a wide offer of controls: control x: room, suction or discharge temperature can be controlled via DDC control (field supplied); control y: control by fixed evaporating temperature; control z: room or suction temperature control via Daikin remote controller. Remote ON/OFF can be achieved by an optional adapter KRP4A51.

1 All wiring, components and materials to be produced on the site mustcomply with the applicable local and national codes.

2 Use copper conductors only.3 For more details, see wiring diagram.4 Install a circuit breaker for safety.5 All field wiring and components must be provided by a licensed

electrician.6 The unit shall be grounded in compliance with the applicable local and

national codes.7 Wiring shown are general points-of-connection guides only and are not

intended for or to include all details for a specific installation.8 Be sure to install the switch and the fuse to the power line of each

equipment.9 Install the main switch that can interrupt all power sources in an integrated

manner because this system consists of the equipment utilizing themultiple power sources.
