WARNING

Hazardous Voltage w/
Capacitors!

Disconnect all electric power,
including remote disconnects before
servicing. Follow proper lockout/
tagout procedures to ensure the
power cannot be inadvertently
energized. For variable frequency
drives or other energy storing
components provided by Trane or
others, refer to the appropriate
manufacturer’s literature for
allowable waiting periods for
discharge of capacitors. Verify with
an appropriate voltmeter that all
capacitors have discharged. Failure
to disconnect power and discharge
capacitors before servicing could
result in death or serious injury.

Normal Chiller Operating Characteristics

Operating Characteristic

Normal Reading

Approx. Evaporator Pressure

(6 to 9 PSIA) (-9 to -6 PSIG)

Approx. Condenser Pressure

(17 TO 27 PSIA) 2 to 12 PSIG

(Standard Condensers)

Oil Sump Temperature:

Unit Not Running

140°F to 145°F

(60°C to 63°C)

Unit Running

80°F to 162°F

(26.6°C to 72°C)

Differential Oil Pressure

18 to 22 psid

Notes:
1. Condenser pressure is dependent on condenser water temperature, and

should equal the saturation pressure of HCFC-123 at a temperature above
that of leaving condenser water at full load.

2. Normal pressure readings for ASME condensers exceed 12 PSIG.
3. Oil Tank Pressure 12” to 18” HG Discharge Oil Pressure 7 to 15 PSIG.
