Introduction
1.3 How to Use this Document
All the contents of this document are written for general air-conditioner facility designers. An air-conditioner facility
designer must provide the most economical and most efficient air-conditioner facility to end-users, comprehensively
taking all aspects of the air-conditioner into consideration, including air, water, refrigerant, environment, energy
consumption, and facility management. In particular, to allow efficient operation of the air-conditioner facility,
management or operation of the air-conditioning system must be examined thoroughly. All aspects of the management
and operation of the air-conditioning system must be designed based on user requirements.
Daikin's controlling equipment described in this document enables designers to fully satisfy user requirements.
Therefore, this document is an essential for source of information for air-conditioning system design.
This document covers almost all of the controlling equipment available from Daikin. This single document enables the
designers to explain the position or functions of equipment, required end-user operations, and prepare a proposal of the
air-conditioning system for a particular property. The designer of an air-conditioner facility can design a controlling
system for the property, and prepare the documents, such as below, for presentation to the end-user:
1. Equipment List: Types and quantities of equipment required
2. System Diagram: Diagram of connections between equipment items
3. Layout Plan for Controlling Equipment: Layout plan for each floor
4. Initial Settings: Minimum settings required for system operation, especially when there is a mixture of control
equipment types.
For the documentation required after satisfying the end user and obtaining the approval for the proposal, please refer to
installation guide and operation guide for the equipment for construction and test-operations. Also, separate Engineering
Data are available for the following products. If more detailed information about anything from total planning to test-
operation is required, or if you are an engineer specialized in control technology itself, our recommendation is to refer to
the Engineering Data:
1. intelligent Touch Controller ED72-423B
2. intelligent Manager ED72-746
3. BACnet

1.4 Safety Precautions
Safety Precautions
For design, installation and maintenance, be sure to read the catalogue, this manual and the installation and operation
manual enclosed in the unit, and to follow their instructions.
Be sure to follow the “WARNING” (Failure to follow these instructions may cause a heavy injury or death.) and the
“CAUTIONS” (Failure to follow these instruction may cause the injury or damage on the property.) described in the
installation manual and etc.
<Cautions when designing the system>
1. Select the right products for your applications.
2. Be sure to consider the safety, electric shock and electric leakage when you design the system.
3. Be sure to follow the instructions in this manual for the operating range, characteristics of performance and limitation
for installation and etc.
<Cautions for the installation/operation>
1. Be sure to follow the safety pre-cautions described in the installation and operation manuals.
2. Be sure to install correctly according to the descriptions of the installation manual. Make sure to perform by the
authorized personnel the works such as a electrical work which requires the qualification.
3. Be sure to perform the commissioning of the system properly, and be sure that the power supply is correct and there
is no electric leakage and other abnormalities, such as abnormal sound, abnormal smell, smoke and etc. Also keep a
record of all the test operating data all the time.
4. Be sure to explain the contents of the operation manual when you hand over the job to the customer, and also ask the
customer to keep this manual wherever the operator can refer to all the time.
5. Hand over to the customer the warranty card duly filled.
