Document Attached: Final Order Acknowledgement
Notes: The most common problems delaying start-up and affecting unit reliability are:
1. Field installed compressor motor power supply leads too small. Questions: Contact the local Daikin Applied sales rep* State size, number and
type of conductors and conduits installed:
a. From Line Power supply to starter
b. From starter to chiller unit (remote mounted)
2.
Centrifugal chillers with water-cooled oil coolers must have a 115-volt normally-closed water solenoid valve installed in the oil cooler water supply
line. Daikin recommends ASCO Type 8210B27 solenoid valve or approved equal and 40-mesh strainer. Daikin does not supply these components.
3. A 115 volt field supplied relay (CP1,2) must be used to start and stop condenser water pump on most applications. Cold condenser water must not
flow through condenser during compressor off cycle. Provisions have been made in control center for connecting CP relay, but must not have a rating
in excess of 100 VA.
