INTRODUCTION
This installation manual concerns VRV inverters of the Daikin
RWEYQ-P series. These units are designed for indoor installation and
used for cooling and heatpump applications.
The RWEYQ-P units can be combined with Daikin VRV series indoor
units for air conditioning purposes.
The present installation manual describes the procedures for unpack-
ing, installing and connecting the RWEYQ-P units. Installation of the
indoor units is not described in this manual. Always refer to the installa-
tion manual supplied with these units for their installation.
2-1 Combination
The indoor units can be installed in the following range.
•
Always use appropriate indoor units compatible with R410A.
To lean which models of indoor units are compatible with

Range for continuous operation
Range for operation
Range for pull down operation
Range for warming up operation
• Operation range of water volume is
13.5~39.5 gpm
•
The unit is designed for the following operation range:
Water temperature: 67~95°F
Water volume: 16 gpm or more
• During cooling operation when the outside temperature is very low, it
is possible that the thermostat switches off automatically in order to
protect the unit from freezing.
• Hold ambient temperature at 35~95°F
Heat-release from the unit: 0.64 kW / hour (Model 72, 84).
It is therefore recommended to always ventilate the room.
