12. RETURNING TO SERVICE: If unit is to be returned to service, replenish reservoirs
with the appropriate volume of distilled water. Proceed to Step 17.
13. FOR DRY STORAGE: If unit is being placed in dry storage, continue with procedure.
14. Drain the water from each reservoir as described in Section 3.4.
15. When all fluid has been removed from the unit, disconnect the drain hose(s) and wipe
unit clean.
16. Unit is now ready for storage. Refer to Section 1.11 for specifications for storage
conditions.
17. Document unit maintenance.
When you are ready to return unit to service, replenish the reservoirs with distilled water.
Perform all the checks as described in this Manual.
2.5 SUGGESTIONS FOR PROTECTING THE RESERVOIR FROM BACTERIA
If hospital procedures require the use of a bacteriostatic or bactericidal agent, use the
suggested guidelines in this manual which are non-acidic and non-foaming.
Do not use De-Ionized or Reverse Osmosis Processed Water. The majority of de-ionizers
do not maintain a neutral pH of 7.
2.6 SAFETY CONTROLS
1. Low Limit Equipment Safety will automatically shut off the compressor if the
cold water reservoir temperature is 2°C ±0.5°C. The low temperature limit LED
will come on and the alarm will sound. This will also shut off the pump which
will stop the circulation of water. The cooling system will come back on after
approximately a 1°C temperature rise above the set point and the alarm will
clear.
Note: This is a redundant system in that there are two independent Low Limit
Equipment Safeties preset at 2°C.
2. Overtemperature Limit Alarm will automatically monitor the actual heat side
reservoir temperature and compare it to the heat side set point. If the actual
display temperature increases above the set point by 1°C for longer than two
(2) minutes the high temperature limit LED on the front panel will flash and the
alarm will sound a short beep. Once the temperatures are within 1°C the alarm
will clear.
3. Primary High Limit Equipment Safety will automatically shut off the heaters
should the warm water reservoir temperature exceed the maximum 42°C and
reach 44°C±0.5°C. The circulating pump will no longer operate. If this happens,
a high temperature limit LED on the front panel will illuminate and the alarm will
sound. The heating system will come back on after approximately a 1°C drop
below the set point and the alarm will clear.
