1.1 About This Manual
EUWA/Y5-30HB/C(Z
) chiller types The Daikin EUWA/Y5-30HB/C(Z) packaged reversible air-to-water chillers are designed for outdoor installation. The EUWA/Y5-30HB/C(Z) units are available in 6 standard sizes with nominal cooling
capacities ranging from 9.1 to 65.2 kW and nominal heating capacities ranging from 11.5 to 72.6 kW.
The EUWA5-30HB/C(Z) unitsare available in6 standard sizes withnominal cooling capacities ranging
from 10.1 to 63 kW.
The EUWA/Y5-30HB/C(Z) units can be combined with Daikin fan coil units or air handling units for air
conditioning purposes. They can also be used to supply water for process cooling or heating.
The present service manual gives you all the information you need to do the necessary repair and
maintenance tasks.
Before starting up the unit for the first time, make sure it has been properly installed. Consult the check
lists in ‘Pre-Test Run Checks’ on page 4-3.
Two controllers The digital controller for chiller types EUWA/Y5-10HB(Z) differs from the digital controller for chiller
types EUWA/Y15-30HC(Z):

(1): Minimum water volume standard thermostat difference setting of 3 K. For reducedsetting multiply
this water volume by (3/new setting). Minimum allowable setting = 0.1 K.
(2): The sound pressurelevel is measured using a microphone at a certain distance from the unit. It is
a relative value, depending on the distance and acoustic environment.
(3): The sound power level is an absolute value indicating the “power”, which a sound source
generates.
Nominal conditions The nominal conditions are as follows:
■entering/leaving water temperature 12/7 °C
■ambient air temperature 35 °C
■power input is total input: compressor + control circuit
■leaving evaporator water temperature from 4 °C to 20 °C (pull-down condition to 25 °C).

(1): Minimum water volume standard thermostat difference setting of 3 K. For reducedsetting multiply
this water volume by (3/new setting). Minimum allowable setting = 0.1 K.
(2): The sound pressurelevel is measured using a microphone at a certain distance from the unit. It is
a relative value, depending on the distance and acoustic environment.
(3): The sound power level is an absolute value indicating the “power”, which a sound source
generates.
Nominal conditions The nominal conditions are as follows:
■entering/leaving water temperature 12/7 °C
■ambient air temperature 35 °C
■power input is total input:
compressor + control circuit.
Operation range The nominal operation range contains a leaving evaporator water temperature from 4 °C till 20 °C
(pull-down condition till 25 °C).
