3 English2. INTRODUCTIONThis installation manual concerns VRV inverters of the DaikinRWEYQ-P series. These units are designed for indoor installation andused for cooling and heatpump applications.The RWEYQ-P units can be combined with Daikin VRV series indoorunits for air conditioning purposes.The present installation manual describes the procedures for unpack-ing, installing and connecting the RWEYQ-P units. Installation of theindoor units is not described in this manual. Always refer to the installa-tion manual supplied with these units for their installation.2-1 CombinationThe 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 withR410A, refer to the product catalogs.• Total capacity/quantity of indoor units〈Outside unit〉 〈Total capacity index of indoor units〉 〈Total quantity of indoor units〉RWEYQ72PTJU ................36 ~ 93.5 12 unitsRWEYQ84PTJU ................42 ~ 109 14 unitsRWEYQ144PTJU ..............72 ~ 187 20 unitsRWEYQ168PTJU ..............84 ~ 218 20 unitsRWEYQ216PTJU ............108 ~ 280 22 unitsRWEYQ252PTJU ............126 ~ 327.5 32 units2-2 Standard operation limitThe figures below assume following operating conditions for indoor andoutside units:Equivalent pipe length ......................................................25 ftLevel difference ..................................................................0 ftCooling HeatingA Inlet water temperature (°F)B Indoor temperature (°FWB)C Indoor temperature (°FDB)Range for continuous operationRange for operationRange for pull down operationRange 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°FWater volume: 16 gpm or more• During cooling operation when the outside temperature is very low, itis possible that the thermostat switches off automatically in order toprotect the unit from freezing.• Hold ambient temperature at 35~95°FHeat-release from the unit: 0.64 kW / hour (Model 72, 84).It is therefore recommended to always ventilate the room.2-3 Standard supplied accessories• Make sure that the following accessories are included.(Check by removing the front panel.)(Refer to figure 1)1. • Operation manual• Installation manual• Clamp (A)• Clamp (B)• Conduit mounting plate2.
