Federal law (USA) restricts this device to sale, by or on the order of a physician. Medivance will not be responsible for patient safety or equipment performance if the procedures to operate, maintain, modify or service the Medivance Arctic Sun are other than those specified by Medivance.
CHAPTER 2 THEORY OF OPERATION Introduction The Model 2000 was designed to control patient temperature with a high level of precision by rapidly altering water temperature in response to a patient core temperature sensor using a closed-loop algorithm. To achieve rapid response with tight control, the system is designed to circulate a minimum volume of water, have a high heating and cooling capacity, and include sensors for real-time feedback of energy transfer.
Page 12
The hydraulic system is composed of two major fluid circuits; the circulating circuit and the chiller circuit (see Figure 2.1). The circulating circuit controls the flow of water to the pads. The chiller circuit provides a constant source of cold water that is pumped, as needed, into the circulating circuit.

where it returns back into the Circulating Tank. Water flows through the leveling line from the Circulating Tank back into the Main Tank. During this cycle, the temperature of the water is controlled by activating the Heater or Mixing Pump. Automatic activation of the Bypass Valve occurs briefly at the beginning of both Automatic Mode and Manual Mode in order to completely prime the Circulating Pump.

Electronic Control System The electronic control system consists of two independent subsystems, the Control and the Monitor. The Control Subsystem performs all of the normal machine operations while the Monitor Subsystem continually monitors important machine operations with independent sensors. If the Control acts incorrectly with respect to the safety of the patient, the monitor will disable pump power, thus preventing inappropriate therapy from being delivered.

is referenced to chassis ground. The other islands are isolated from the Backplane island by opto-isolators or transformers. The RS-232 #1, RS-232 #2, and Temperature Out (Echo) islands are isolated from the Backplane and from each other to a breakdown voltage of at least 500V. The patient temperature island is isolated from all others to a level of 1500V.
Installation of Cables and Accessories 1. Unpack the Model 2000 and accessories. 2. Adjust the Control Module handle to a vertical position and secure by tightening the knobs on both sides. 3. Connect the Remote Display Cable to the back of the Remote Display.
“Alarm 5: Water level below minimum. Fill reservoir or purge pads”. 3. Clear the alarm by pressing the alarm key. 4. The display reads:” Medivance Arctic Temperature Management System”. Filling the Control Module 1. Add one vial of Arctic Sun Cleaning Solution to 4 liters of sterile or distilled water.
Adjust Remote Display Clamp Tools and Supplies Required: 1/2” hex key. The Remote Display clamp tension may need adjusting over time. 1. Remove the Remote Display from the handle. Disconnect the Remote Display Cable. 2. Loosen the clamp knob until the bottom jaw swings clear of the top head.
Clean the Condenser The Arctic Sun condenser fins should be inspected for dirt and debris every three months or more often with heavy use or dusty environment. The condenser is located underneath the grill on the front of the control module. 1.
Drain and Replace Fluid Tools and Supplies Required: Arctic Sun Drain Bag It is recommended the Control Module be drained and refilled every 3 months to assure a satisfactory concentration of Cleaning Solution in the circulating water. In addition, draining is required for replacement of some components or prior to shipment or storage.
Replace Internal Filters Tools and Supplies Required: 5/32” hex key 11/32” nut driver Arctic Sun Drain Bag (2) Arctic Sun Internal Filters Replace the Circulating Pump Filter Unplug the power cord. Remove the cables and lines attached to the rear panel; the Fluid Delivery Line, Fill Line, Patient Temperature Cables, Rear Panel Removal and Remote Display Cable.
Replace the Mixing Pump Filter Remove the front grill by first pulling the bottom out by reaching under the center of the bottom edge. Using both hands at the top sides of the panel, pull it straight out and away from the control module. Remove the sheet metal access panel under the grill by unscrewing the four nuts with the nut driver.
CHAPTER 5 CALIBRATION AND SAFETY CHECK The Calibration and Test Unit The Model 2000 Calibration and Test Unit (CTU) is an instrument that is used to calibrate the Model 2000 Control Module. It is a hand sized unit that connects directly to the fluid delivery line port, taking the place of the Model 2000 fluid delivery lines and pads.
To clean the CTU, spray a mild detergent solution onto a towel and wipe down the unit. Do not submerge the unit in water. If heater becomes inoperative, return the CTU to Medivance for service. An open fuse is indicative of a problem that requires immediate service.
5.1.6 Environmental Requirements The Calibration Test Unit should be stored and used in specific operating conditions: Ambient Temperature Range: Operating Temperatures: ............. 18ºC to 24ºC (65ºF to 75ºF) Storage Temperatures:............... -30ºC to 50ºC (-20ºF to 120ºF) Ambient Humidity Range: Operating Relative Humidity............5% to 95% non-condensing Note: If the CTU is used at a room temperature outside of the specified operating range, the test system’s accuracy will be degraded.
Note: If an alarm occurs during calibration, check the CTU connections and switch positions. If the alarm persists, power down and start over. If the alarm persists, call Medivance Service. Note: The calibration process can be aborted and restarted at any time by pressing Enter.
5.2.2 Stage 4: Temperature Out Calibration 1. Press the Enter Key if calibration is desired. The sequence may be aborted at this stage if only verification is desired. 2. The “Calibrate System” menu screen displays the number of “Cal Hours” that have elapsed since the system was last calibrated.
11. Press the Home Key. 12. Allow the water temperature to stabilize at 42°C for at least 5 minutes. Note: It is important to allow the temperature to fully stabilize at 42°C. If it does not, it may not be possible to attain the alarm conditions.

CHAPTER 6 TROUBLESHOOTING Diagnostic Mode The Model 2000 has a diagnostic mode which is designed to provide assistance with troubleshooting and provides access to the Calibration software. To enter this mode, power up the Control Module while holding the Automatic and Purge Mode keys located on the Remote Display. The keys must be held for at least 5 seconds.

Card Cage Indicators and Test Points LEDs on the edges of the cards indicate the status of major functions and may be helpful in troubleshooting. (Figures 6.4 to 6.7) Access to the power supply voltages is also available at the card edge.
For component replacement instructions, see Chapter 7. Note that this guide assumes that no special equipment, such as the Medivance Calibration Test Unit is available. If available, the Calibration Test Unit is a powerful diagnostic tool and it should be used in association with the instruction in its manual.

Troubleshooting Alarms and Alerts The Arctic Sun is designed with the patient's and operator's safety in mind. The Control Module has redundant, cross-checking systems and a multitude of self-tests. It detects inappropriate conditions and notifies the user. Many of these conditions can be addressed by clinical actions alone. These are described in the Operator's Manual.
