Can Be Installed for Each Floor
Since the external hydrostatic pressure of the outdoor unit fan motor is 6 mm H2O, an outdoor unit can be placed on each floor using short-discharge ductwork.
* Refer to pages 23 and 24 for details about Advanced Controllers.
Unique piping and wiring systems and lightweight, compact indoor units make it possible for just a few people to install a VRV system quickly and easily. The Auto Address Setting function and the Auto Check function for piping and wiring errors allow anyone with just the ability to install regular direct expansion type air conditioning equipment to perform a highly reliable installation.

Super Wiring System

A Super Wiring system is used to enable the shared use of the wiring between indoor and outdoor units and the central control wiring. A high-level central control system can be achieved via a relatively simple wiring operation. Even when retrofitting with a central control system, all that is required is to connect the central control unit to the outdoor units.

Conventional

Super wiring system

Outdoor unit

Reduced Piping and Cost
Daikin's advanced REFNET piping system makes installation easy. Only two* main refrigerant lines are required in one system, and the strainers, stop valves, two-way and three-way valves, used in conventional water piping systems are not required. Thanks to the REFNET piping system and electronic expansion valves, imbalances in refrigerant flow between units is greatly reduced even though small-diameter piping is used. The smalldiameter piping is also easy to handle and requires less piping shaft space. (* Three in the case of heat recovery type.)
Central remote controller

Indoor unit

Auto Address Setting Function
The address of each indoor unit is set automatically at the same time they are connected, thus eliminating the need to manually set each address. Address setting for central control can be performed easily from the remote controller of an indoor unit.

Sequential Starting

By employing D -net, systems on the same power line will be started sequentially. This holds down the starting current, allowing the capacities of breakers to remain small (possible up to 100 HP).
Four-Way Wiring and Piping Connection

REFNET Joint ATTACHED INSULATORS for REFNET Joint
The REFNET Joint and REFNET Header (both optional) reduce the amount of work involved in installation and increases the reliability of the system.
REFNET Header for REFNET Header
Wiring can be fed from the front panel, both left and right side panels or bottom panel of the outdoor unit. Piping can be fed from 4 directions, front, both left and right or bottom of the outdoor unit.
These features increase installation flexibility, minimizing the space required for installation and simplifying maintenance of the wiring and piping.

Front Bottom Left Right

Simple Wiring
Two-wire multiplex transmission system makes it possible to connect multiple indoor units to one outdoor unit with one 2-core wire, thus simplifying the wiring operation.
Power supply Front Bottom
Note: Refer to engineering data for details of the exterior design of the outdoor unit and the locations of connection points for piping and wiring.
Check Function for Connection Errors of Wiring and Piping
Twin cable multiplex transmission system
Mistakes in piping or wiring in the system can be checked via lamps on the printed circuit board of the outdoor unit.
Self-Diagnosis Function for Efficient Servicing and Maintenance
The self-diagnosis function detects malfunctions in major locations in the system and displays the type of malfunction and location. This allows servicing and maintenance to be performed more efficiently.
The VRV system is an advanced system that offers convenience and comfort for end users.
Precise Room Temperature Control
Electronic expansion valves respond to changes in load in indoor units and continually control the flow rate of refrigerant. In this way, the VRV system maintains a nearly constant room temperature without the typical temperature changes that occur with a conventional ON/OFF control system. The extremely refined PID control maintains the room temperature within 0.5C of the set temperature. (Cooling)

Auto Swing

Whether it be a ceiling-mounted cassette (double- flow/multiflow/600 x 600 multi-flow) type, ceiling-mounted cassette corner type, ceiling-suspended type or wall-mounted type, all these indoor units have an Auto Swing mechanism that helps keep the room temperature uniform.
Low Operating Sound Design
All indoor units have a low operating sound design.

LCD Remote Controller

The remote controller uses an easy-to-read liquid crystal display for easy operation. A full line of wired and wireless controllers is available for the indoor units of all types.

Auto Restart Function

Even if there is an extended power failure, the VRV system will automatically restart operation. A power failure will not cause any settings to be lost, thus eliminating the need for re-programming.

Daikin's HRV (Heat Reclaim Ventilation) recovers heat energy lost through ventilation and holds down room temperature changes caused by ventilation, thereby maintaining a comfortable and clean environment. This also curbs the load on the air conditioning system and conserves energy. In addition, the HRV is interlocked to Daikin's VRV system, SkyAir and other air conditioning systems an d automatically switches over ventilation mode, further increasing the effects of energy conservation. HRV operation has been centralized on the air conditioner remote controller allowing total control over air conditioning and ventilation with a simple configuration.

Sound Level dB(A) [50Hz/60Hz]

-10 -20

Note: 1. Sound level is measured at 1.5m below the center of the body. 2. Air flow rate can be changed over to Low mode or High mode. 3. Sound level is measured in an anechoic chamber. Sound level generally become greater than this value depending on the operating conditions, reflected sound, and peripheral noise. 4. The sound level at the air discharge port is about 8 dB higher than the unit's sound level. 5. Even when the outdoor temperature is below -15C, the system is operable down to -20C with the preheater installed at the outdoor air intake side.

Precautions

System/ Precautions on
Refrigerant Refrigeration oil Condensing pressure R22 Mineral oil (Suniso) 1.84MPa (18.8kg/cm 2) R410A Synthetic (ether) oil 2.97MPa (30.3kgf/cm 2)
(Single-component refrigerant) (Quasi-azeotropic mixture refrigerant)

Installation

Several dedicated tools are required for the installation work of R410A models. Some of conventional tools can be used except tools actually used to the installation work for R22 models.
R410A applies higher pressure than R22 and uses refrigeration oil different from R22. Therefore, piping works and tools are also different from those for R22 refrigerants.
Refrigerant Piping Materials

REFNET piping materials

Branch pipe and dividing pipe for R410A are provided specially for REFNET piping. Since these new parts are not interchangeable with current REFNET parts, do not use current REFNET piping materials for R410A. (Refer to the option list)

Tool name Pipe cutter

Work process / Usage Pipe cutting Pipe flaring Applying to flared section Flare nut jointing Pipe expanding in connection of pipe Pipe bending Air tight test Oxidation proof for inside pipe Pipe brazing
Interchangeability with conventional tool Interchangeable and can be used. Dedicated flaring tool is required due to flaring dimension change. Use dedicated ether oil, ester oil, alkyl-benzene oil or mixture of these oils. Dedicated torque wrench is required due to different size of 1/2 "and 5/8" flare nuts.
Other refrigerant piping materials
Use C1220 type copper tube for refrigerant piping. Wall thickness of copper tube shown in the below table can be applied. (The table is same as the recommendation for R22)
