Water Over Temperature Alarm; Alarm Testing; Performance Testing - Smiths Level 1 H-1000 Operator's And Service Manual

Water Over Temperature Alarm

Press and hold the Water Over Temperature alarm test button on the power and test panel
on the front of the unit. The display will jump to 45 °C (as long as the button is pressed
on), and the red over temperature indicator will illuminate and the audible alarm will start to
pulse.
NOTE: The Water Over Temperature Alarm test button actually tests the over temperature
circuitry of the system, not just the visible red display indicator and the audible alarm.
NOTE: Pressing the Water Over Temperature test button or the Alarm test button will disable the
H-1000 even after the buttons have been released. The unit must be shut off and then re-started to
clear the alarm condition.

Alarm Testing

The audible alarm and all indicator lights may be tested by pressing the Alarm test button
on the power and test panel on the front of the cabinet.
NOTE: Pressing the Alarm test button or the Water Over Temperature test button will disable the
H-1000 even after the buttons have been released. The unit must be shut off and then re-started to
clear the alarm condition.

Performance Testing

Periodic testing of the overall operating efficiency of the H-1000 can be accomplished in
one of two simple ways:
1. COLD START TEST
NOTE: This performance test requires a non-sterile, not for patient use Level 1
disposable set to be installed properly on the H-1000.
Store the H-1000 unit in a room where the room temperature is approximately 21 °C
(70 °F). With a non-sterile D-series disposable set in place, note the time, and then turn
the power switch ON. The green "OPERATING" indicator will illuminate. Rapidly rising
numbers will appear on the circulating water bath temperature display. A 41 °C
temperature reading will appear in approximately 3 to 7 minutes on an efficiently operating
unit.
NOTE: If the H-1000 does not pass the cold start test, it should be returned to Smiths
Medical or an authorized distributor of Smiths Medical for service. Do not attempt to
change the calibration settings.
2. THERMAL CALIBRATION WELL (TCW)
Available from Smiths Medical, a TCW may also be used to test performance and confirm
proper calibration of the water bath temperature.
