Trane Series R™ Helical Rotary Chiller RTAC140H

Suction line isolation valve is closed

Oil return line service valve is closed

Liquid line service valve is closed

Select the method used to move refrigerant from the condenser to evaporator

NOTE: If a pump is to be used, connect it before closing this valve. This port is only isolated when the valve is back seated. If a vacuum pump is used, then connect it to the discharge line service valve near the oil separator.

Evaporator is large enough to hold all the charge for any unit to below the center-line of the shell

Liquid line service valve is shut

Oil return line service valve is shut

Circuit started with the service tool (access compressor service view in Techview)

Discharge check valve closed after unit trip

Discharge isolation valve is closed

Oil line shut off valve is closed

Refrigerant remainder recovered

NOTE: Remaining vapor can be recovered/stored in the high side of the system. Be certain to follow proper recovery procedures to avoid introduction of non-condensable gases.

Isolate the refrigerant charge outside of the compressor and close all four valves leading to the compressor?

Disconnect power to the chiller. Remove the electrical junction box cover and disconnect the wires?

WARNING: Hazardous Voltage! Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury.

Evacuate the compressor through the service fitting provided. If the unit does not have suction service valves, this will include evacuating the low side of the system as well?

Disconnect all four lines attached to the compressor, as well as the junction box. Remove three screws from the bottom of the compressor?

Remove the compressor by sliding it out of the chiller onto a well supported skid or other platform. The compressor is very heavy, so insure that the support is sturdy. A piece of 1x4 lumber placed between the isolators works well to support the compressor feet as it is pulled from the chiller?

Install the new compressor. Reinstall all lines, wires, and screws. Open the service valves, and trim charge as required?
