Carrier 17/19EX - Manual (Page 249)

Inspect the Starting Equipment
Before working on any starter, shut off the machine, and open all disconnects supplying
power to the starter.
CAUTION CAUTION
!
Water must be within design flow limits, clean, and treated to ensure proper
machine performance and reduce the potential of tubing damage due to corro-
sion, scaling, erosion, and algae. Carrier assumes no responsibility for chiller
damage resulting from untreated or improperly treated water.
The disconnect on the starter front panel does not deenergize all internal circuits.
Open all internal and remote disconnects before servicing the starter.
