*Available as an option on 17EX chillers.

²The compressor and gear oil pump contactors are wired together on the line side. Their amperage values must be added together when sizing conductors.

NOTE: The oil pump is powered through a ®eld wiring terminal into the power panel. Power to the controls and oil heater via the power panel must be on circuits that can provide continuous service when the compressor starter is disconnected.

*To ensure relief valve serviceability, and as required in ASHRAE 15, latest edition, three-way valves and redundant relief valves are in- stalled on the storage vessel. Only one of the ``No. of Valves'' listed are in service at any time.

NOTES:

1.The cooler relief C-factor is for both cooler and condenser vented through the cooler in accordance with ASHRAE (American Society of Heating, Refrigeration, and Air Conditioning Engi- neers) 15, latest edition.

2.Relief valve discharge pipe sizing is to be calculated per latest version of ASHRAE 15, using the tabulated C-factors and nom- inal pipe size listed above. Cooler and economizer/storage vessel rated relief valve pressure is 225 psig (1551 kPa).

3.The pumpout unit condenser contains less than 110 lb (50 kg) of HFC-134a, which is a Group A1 refrigerant. The ASHRAE 15 stand- ard exempts small-volume vessels from the requirement to vent outside. However, Carrier recommends that the pumpout con- denser be connected to the rest of the vent system.
