Trane CVHE-SVU01E-ENX39640712050 manual Hazardous Voltage w/ Capacitors, Weekly Maintenance

Periodic Maintenance

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.

Note: For additional information regarding the safe discharge of capacitors, see PROD-SVB06A-EN or PROD-SVB06A-FR

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.
