Split - Sky Air

Daikin’s unique position as a manufacturer of air conditioning equipment, compressors and refrigerants has led to its close involvement in environmental issues. For several years Daikin has had the intention to become a leader in the provision of products that have limited impact on the environment. This challenge demands the eco design and development of a wide range of products and an energy management system, resulting in energy conservation and a reduction of waste.

ISO14001 assures an effective environmental management system in order to help protect human health and the environment from potential impact of our activities, products and services and to assist in maintaining and improving the quality of the environment.

Daikin Europe N.V. is approved by LRQA for its

Quality Management System in accordance with the ISO9001 standard. ISO9001 pertains to quality assurance regarding design, development, manufacturing as well as to services related to the product.

Daikin units comply with the European regulations that guarantee the safety of the product.

Sound pressure level is a relative value, depending on the distance and acoustic environment. For more details, please refer to sound level drawings of this chapter.

The sound power level is an absolute value indicating the power which a sound source generates.

Sound values are measured in a semi-anechoic room.

In case of drain piping for outdoor unit, drain piping kit (option) is needed.

Nominal cooling capacities are based on : indoor temperature : 27°CDB, 19°CWB, outdoor temperature : 35°CDB, equivalent refrigerant piping : 7.5m, level difference : 0m.

Nominal heating capacities are based on : indoor temperature : 20°CDB, outdoor temperature : 7°CDB, 6°CWB, equivalent refrigerant piping : 7.5m, level difference : 0m

NOTES

1. RLA is based on the following conditions:

Indoor temp.: 27°CDB/19.0°CWB

Outdoor temp. : 35°CDB

2. TOCA means the total value of each OC set

3. Voltage range

Units are suitable for use on electrical systems where voltage supplied to unit terminals is not below or above listed operation range limits

4. Maximum allowable voltage unbalance between phases is 2%.

5. MCA/MFA

MCA = 1.25 x RLA + all FLA, MFA = < 2.25 x RLA + all FLA (next lower standard fuse rating Min. 16A)

6. Select wire size based on the larger value of MCA or TOCA

7. Instead of fuse, use circuit breaker

8. For more details concerning conditional connections, see http://www.daikineurope.com/extranet, select ’’Daikin Documentation’’ and select

’’conditional connection’’, ’’the requested product type’’ and ’’English’’ from the drop down lists, click the search button.

11 Installation

11 - 1 Installation method

REQ71 ∼ 125B

Oil trap

Indoor unit

Oil trap

Outdoor unit

Gas piping

Liquid piping

NOTE:

Since there is fear of the oil held inside the riser piping flowing back into the compressor when stopped and causing liquid compression phenomenon, or cases of deterioration of oil return, it well be necessary to provide a trap at an appropriate place in the riser gas piping.

A trap is not necessary when the outdoor unit is installed in a higher position than the indoor unit.

Obstacle is present

In these cases, close the bottom of the installation frame to prevent discharged air from being bypassed.

In these cases, only 2 units can be installed.

This situation is not allowed.

Figures between ( ) indicate the dimensions only for the

100-125 class models.

Do not stack more than one unit.

About 100mm is required as the dimension for laying the upper outdoor unit’s drain pipe.

Get the portion A sealed so that air from the outlet does not bypass.

C. Multiple-row installation

1. Installation of one unit per row 2. Installing multiple units (2 units or more) in lateral connection per row

Notes:

- Depending on operation and installation conditions, the indoor unit can change over to freeze-up operation (indoor de-icing).

- To reduce the freeze-up operation (indoor de-icing) frequency, it is recommended to install the outdoor unit in a location not exposed to wind.
