Functional checks (Continued)
5. Plug the
T/Pump
®
Temperature Therapy Pump
into a properly grounded Hospital Grade receptacle.
Notes
• The T/Pump
®
Temperature Therapy Pump performs a self test of the lights and audible alarm, with light pattern and
short audible beep
• The T/Pump
®
Temperature Therapy Pump goes to Standby mode with only the Standby light on.
6. Press the On/Standby button. The T/Pump
®
Temperature Therapy Pump starts running at the default Setpoint of 100° F
(38° C)
Notes:
The Control and Over Temperature processor are reading the room temperature. The processor in turn
supplies heat, to bring up the temperature past the setpoint. This will drive the water flowing through the system to a
temperature that will trip the thermostat (in approximately 10 to 15 minutes).
7. Record the peak temperature read by the thermometer. The temperature recorded must be between 110° F (43.3° C)
and 120° F (49° C).
Notes
• If the thermostat operates outside of its intended temperature range, it must be replaced.
• After the thermostat trips, the system will cool down to a temperature that resets the thermostat (in
approximately 20 to 25 minutes). This Trip/Reset cycle will continue until the unit is put back into Standby mode.
8. Press the On/Standby button. The T/Pump
®
Temperature Therapy Pump goes into Standby mode.
9. Unplug the
T/Pump
®
Temperature Therapy Pump.
10. Unplug the Test probe. Plug the Original Temperature Sensor back in.
11. Close the unit and reinstall the screws removed in steps 2 through 5.
12. Verify proper operation before returning the product to service.
Water leak check
1. After completing the backup limit thermostat test, tilt the product toward you so the front is down. Hold it in this position
for 3 minutes.
2. Return the unit to the upright position.
3. Check the reservoir tray joint for water leaks.
4. Turn the product so that the back is facing you. Tilt the product toward you so the back is down. Hold it in this position for
3 minutes.
5. If a water leak is found, see service Reservoir on page 26 .
Ground resistance check
WARNING
Risk of electrical shock. Make sure that the product is unplugged when performing the ground resistance test.
• Using a ground resistance meter, measure the resistance between the ground pin on the plug and the brass manifold
block, see
Figure 5 on page 25 item 6. You can access the ground through the hole where the hose connects to the pump
(see Figure 4 on page 20 ).
Notes:
The value should not be more than 0.5 ohm.
