1 Design, Installation & Testing InstructionR-410A Heat Recovery 60 HzREYQ96 MTJUREYQ192 MTJUSiUS39-506 PrefaceThis system is a modular zone controllable air conditioning system of great sophistication which is capable of assembly in a variety of different configurations. It would, however, be no exaggeration to say that the full potential of the systems functions can only be achieved in combination with the skills of those involved in the design of the equipment itself and those responsible for the Installation the move towards intelligent buildings has gathered momentum, so we have also been seeing ever more a growing demand for a wider range of independently controllable building related this background there have also quite naturally been calls for the development of more distributed types of air conditioning systems while at the same time taking full account of the need to use energy economically by demand matching in view of the huge annual increases in the demand for electric power seen in recent have therefore prepared this Installation manual to enable Installation work to be handled confidently on the basis of a clear understanding of the special features of this system.

2 We have paid particular attention to points of difference in Installation procedure between this system and the more traditional package and room air conditioning manual is designed specifically to cater for those supervising Installation work and concentrates on those products which are currently on the market. Essential points which need to be taken into consideration when designing an appropriate configuration for the system and in each of the separate Installation processes have also been have also added a section covering problems which have arisen in connection with Installation work undertaken to date in an attempt to prevent the recurrence of the same be sure to read this manual thoroughly before starting Installation work in order to ensure that all such work is carried out with maximum efficiency and to maximum following technical documents are also available from Daikin. Please use these documents together with this manual to conduct efficient Manual VRVII R-410A Heat Recovery 60Hz Series SiUS39-506 Sept.
