Trane Series R™ Helical Rotary Chiller RTWD180HIGH

Clean all water strainers in both the chilled and condensing water piping systems

See “Refrigerant and Oil Charge Management,” p. 65. If chiller measurements vary significantly from values listed in Table 23, p. 65 and Table 24, p. 65, problems may exist with refrigerant and oil charge levels.

Contact local Trane service if measurements vary significantly?

Warning: This procedure requires trained personnel with PPE!

WARNING: Hazardous Voltage! Failure to disconnect power before servicing could result in death or serious injury. Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/ tagout procedures to ensure the power can not be inadvertently energized. Verify that no power is present with a voltmeter.

Power disconnected and verified with a voltmeter?

Shut down the chiller once each year to check the following:

Perform all weekly and monthly maintenance procedures.

Oil analysis performed by a qualified laboratory to determine system moisture content and acid level?

Note: Due to the hygroscopic properties of the POE oil, all oil must be stored in metal containers. The oil will absorb water if stored in a plastic container.

Chiller leak checked, safety controls inspected, and electrical components inspected for deficiencies by Trane service organization?

All piping components inspected for leakage and/or damage? Inline strainers cleaned?

Areas showing signs of corrosion cleaned and repainted?

After the unit has operated for approximately 30 minutes and the system has stabilized, check the operating conditions and complete the procedures below:

Check evaporator and condenser pressures with gauges and compare to the reading on the unit chiller.

Pressure readings should fall within the specified ranges listed in Table 23, p. 65 and Table 24, p. 65. If chiller measurements vary significantly from values listed, problems may exist with refrigerant and oil charge levels. Contact local Trane service.

Note: Optimal condenser pressure is dependent on condenser water temperature, and should equal the saturation pressure of the refrigerant at a temperature 2 to 5°F above that of leaving condenser water at full load.

Sign off on the weekly maintenance check.

Once service is complete, the waterbox/ cover should be reinstalled following all previous procedures in reverse.

New o-rings or gaskets used on all joints after thoroughly cleaning each joint?

Contact local Trane parts center for information.

Note: Torque bolts in a star pattern. See the table below for torque values.
