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 representative. State size, number and type of
conductors and conduits installed:
a.
From 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
Applied 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 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.
4.
Refer to NEC Article 430-22 (a)
*Does Not Apply to Magnetic Bearing Chillers (WMC/WME)
