7 ADDITIONAL GUIDELINES FOR MODULAR APPLICATIONS
This chapter is as an integration of the manual for modular applications. All the indications reported outside
this chapter, for single unit installation, must be considered still valid.
The three models EWWT100-125-160Q may connect together in a system using standard Daikin master/slave (MUSE) serial
connection.
The system is equipped with:
• Two or more chiller modules, up to 4 modules connected together.
• Power supply bars system (external accessory, not standard)
• Water manifold module (external accessory, not standard)
• Pump module (external accessory, not standard)
The possible combinations of the modules are reported in Table 5.

installation the order of modules is not mandatory, it can vary from the dispositions showed in the table.
Water manifold module installation
7.1.1 Connection between manifold module and chiller unit
In case of modular application, the units shall be connected on the water side through manifold modules. The manifold allows the
connection between the unit heat exchangers and the customer plant.
The manifold modules can be:
• Supplied by Daikin for each specific installation.
• Designed by the customer.
When the manifold modules are designed by the customer, the guidelines in this chapter shall be followed for a proper design.
