Checking the Coolant Level 7.1
1. Once a week, check the coolant level of the T257P system
2. Set the system in RUN Mode.
3. Open the reservoir cap and check the fluid level in the reservoir. If the level is below the
reservoir neck, add recommended fluid to fill it. Please refer to the technical information
section for recommended coolants.
4. Close the cap, finger tight, when complete.
Changing the Coolant within the T257P System 7.2
1. Disconnect power to the unit by turning the power switch to the off position.
2. Disconnect the unit from the application by depressing the CPC fittings thumb tabs and gently
remove the hose connectors from the unit connectors. If the connections are other than CPC,
please refer to the specific connector manufacture’s recommended practice for installation /
removal of connectors.
3. Connect the drain hoses (with the CPC male connectors on one side and open tube on the
other) to the supply and return ports and drain the fluid into a discard vessel.
4. Turn on the unit and set the unit in Run Mode.
5. Keep adding fresh fluid of 500 ml, into the reservoir to circulate it through the system and
pump it out to the discard vessel.
6. When all the fluid is emptied from the reservoir, the system will issue a “Low Coolant Level”
alarm message. Disconnect the drain hoses and reconnect the Chiller to the application.
7. Add fluid to the reservoir; press “Accept” to clear the alarm.
8. Start the system and add fluid as required for the fluid level to be at the bottom of the
reservoir neck.
9. Once complete, close the cap.
10. It is recommended that a coolant change be implemented at minimum, every six months, to
keep the system in working order. Based on your use conditions, you may need to perform
this PM more frequently.
Changing the Application Coolant 7.3
1. It is highly recommended the fluid contained within the application also be flushed when the
T257P Chiller coolant is changed.
2. Follow application guidelines for flushing procedure.
