PREFACE
The latest technological innovations of air conditioners make remarkable progress. We are not able to perform our duty
without mastering the proper basic theory and knowledge in service skills and techniques.
The field of VRV system particularly
shows such a rising tendency. The techniques on trouble shooting and trouble removing corresponding to the
computerized and systematized products are required. Based on these requests, therefore, we have prepared this
manual, emphasizing the understanding on VRV system.
We wish that you would use this manual as a guidebook for the service of VRV system or as a reference book for
education of service personnel, which leads to the development of skills in whole service group of Daikin.
