Service Manual
Electronic Control System
The electronic system consists of two independent
subsystems: control and monitor. The control subsystem
is responsible for delivering therapy to the patient. The
monitor subsystem confirms the safe operation of the
control subsystem. Each subsystem has an independent
microprocessor, audio alarm, and both water and patient
temperature sensing circuits.
The control subsystem performs the following functions:
• Command interpretation from the Control Panel
• System information update to the Control Panel
• Circulation Tank water temperature control (T1 & T2)
• Circulation Pump speed control from pressure sensor (P1)
• Patient temperature measurement (PT1)
• Temperature Out signal generation
• Chiller Tank water temperature control (T4)
• Valve control (VV, BV and FV)
• Chiller control
The monitor subsystem performs the following functions:
• Redundant command interpretation from Control Panel
• Circulation Tank temperature monitoring (T1)
• Patient temperature measurement (PT2)
• Circulation Pump power interrupt control
• Power Circuit Card voltage monitoring
Chapter 4- Maintenance
Maintenance Schedule
Routine maintenance and service should be performed
on the Arctic Sun™ Temperature Management System
Control Module every 6 months at a minimum. This
consists of cleaning the external surfaces, accessories and
chiller condenser, inspecting the device, and replenishing
the internal Arctic Sun Cleaning Solution that suppresses
microorganism growth in the water reservoir and hydraulic
circuit.
Procedure Interval

surfaces
After each use
Inspect Connectors and Cables 6 months
Clean the Condenser 6 months
Replenish Arctic Sun Cleaning
Solution
6 months
Inspect Screen Protector 6 months
Inspect Fluid Delivery Line 6 months
Inspect Manifold O-Rings 6 months
Calibration
Every 2000 hours or
250 uses, whichever
occurs first, as
indicated by system
display
Clean the External Surfaces
After use, the external surfaces of the Arctic Sun™
Temperature Management System may be a potential
biohazard. The Arctic Sun™ Temperature Management
System external surfaces should be manually cleaned,
disinfected and visually examined per the instructions below.
Prior to cleaning :
1. Use appropriate personal protective equipment
(e.g. gloves, eyewear, face mask or shields) per
manufacturer’s guidelines for the enzymatic spray
to protect user from exposure to both chemicals and
microorganisms.
2. Apply the castor brakes on the Arctic Sun™ Temperature
Management System.
3. Unplug the power cable from the wall outlet.
4. Straighten the power cable.
5. Disconnect all other cables and hoses from the Arctic
Sun™ Temperature Management System and straighten
them.
Manual Cleaning:
• Timing
Clean the Arctic Sun™ Temperature Management
System external surfaces as soon as practical after use
(e.g. at the point of use).
• Cleaning Materials
Required: Neutral-pH Enzymatic spray cleaner; clean,
dry cloths
Validated : Medline Bio-Zolve Instrument Presoak Spray
• Cleaning
1. Saturate a clean, dry cloth with the Enzymatic
cleaner and remove all heavy soil loads from the
external surfaces of the Arctic Sun™ Temperature
Management System.
2. Saturate a second clean, dry cloth with the
Enzymatic cleaner and thoroughly wipe all external
surfaces of the device.
a) Ensure that all surfaces are dampened,
including seams of the device.
b) Use as many additional clean cloths
saturated with the Enzymatic cleaner as
necessary to ensure device is completely
dampened.
c) Thoroughly wipe the following with
additional clean cloths saturated with the
Enzymatic cleaner – fluid delivery line,
power cable, temperature cables, USB cable,
RS232 cable.
3. Allow surfaces to remain treated for a minimum of two
(2) minutes.
4. Use a clean, dry cloth to remove remaining cleaning
solution.
Required accessories and supplies can be ordered separately.
