Field installed compressor motor power supply leads too small. Questions: Contact the local Daikin Applied sales representative. State size, number and type ofconductors and conduits installed:a. From Power supply to starterb. 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. DaikinApplied recommends ASCO Type 8210B27 solenoid valve or approved equal and 40-mesh strainer. Daikin Applied does not supply these components.3. A 115-volt field-supplied relay (CP1,2) must be used to start/stop condenser water pump on most applications. Cold condenser water must not flow throughcondenser 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.4.
