NOTE: If both thermostats reset, both
thermostats have tripped. This is
acceptable.
NOTE: Use care when resetting the
thermostats since the power terminals are
delicate. Avoid flexing the terminals.
Thermostats with loose terminals should
be replaced and retested. Be certain the
thermostats have cooled for 5-10 minutes
before resetting.
NOTE: If thermostat S2 does not reset, the
heater overtemp thermostat has tripped.
In the unlikely event that this has
occurred, perform the following:
a) remove the filter retainer and nut;
b) remove the filter;
c) jumper the S4 heater overtemp
thermostat; and
d) replace the filter, filter retainer, and nut.
Return to step 25.
35. Reconnect the thermistor to the control
board.
36. Put the enclosure back together and secure
it with tape.
37. Plug in the Power Unit. Turn it on.
38. Run the Power Unit for 5-10 minutes in the
46°C setting to stabilize the system
temperature.
NOTE: Perform the following steps 39 through
44 as quickly as possible, to prevent the Power
Unit from cooling down:
39. Unplug the Power Unit. Carefully separate
the enclosure slightly.
40. Unplug the thermistor (item 12, fig. 10, p.
25) from the back of the control board.
41. Put the enclosure back together and secure
it with tape.
42. Plug in the Power Unit and turn it on. Leave
unit in 32°C temperature setting. Have a
stopwatch ready.
NOTE: Do not set the TEMPERATURE
SETTINGS switch to fan only since this
setting disables the heater.
43. The temperature should start to increase.
When the air temperature reaches 48°C, start
the stopwatch. Allow the Power Unit to heat
until thermostat S3 trips. Stop the stopwatch
and note the highest temperature displayed.
This is the upper limit temperature for
thermostat S3. Record the time and
temperature on the
INSPECTION FORM
(table 2, p. 17). Plot these values on table 2,
page 18.
44. Verify that the REMOVE FROM USE light is lit.
45. Unplug the Power Unit.
46. Open the enclosure and allow the Power Unit
to cool for 5-10 minutes.
47. Thermostat trip acceptance
Both thermostats must trip within the
acceptance window (see table 2, p. 18).
If this condition is not met, do not put the
Power Unit in service. Contact your dealer for
assistance.
48. Remove the jumper from the patient limit
thermostat.
If a jumper was used on the S4 heater
overtemp thermostat, remove the filter
retainer, nut, and filter. Remove the jumper
from S4. Reset S4 (indicated by an audible
"click" and tactile feedback). Replace the filter,
filter retainer, and nut.
After performing the preceding test
procedure, verify that all test jumpers
have been removed before returning
the Power Unit to patient use.
Failure to remove the test jumper
may result in death, serious injury, or
equipment malfunction.
49. Reconnect the thermistor connector.
