SECTION 1. INTRODUCTION
To provide the maximum patient safety during the use of the HEMOTHERM Model 400CE
Dual Reservoir Cooler/Heater system, a thorough knowledge and understanding of the
system, and its correct application and operating use are required. Each person who is
responsible for use or direction of use of the system, such as physicians, perfusionists,
technicians and operators must read and understand this operating manual and all
precautions and warnings prior to use. It is recommended that this manual be reviewed at
least semi-annually as a refresher for safe operation and application. For proper knowledge
and understanding, in-service is available upon request.
All service associates, who interface with this equipment, must read and understand this
Operation Manual in its entirety prior to maintaining or operating the equipment.
1.1 GENERAL SAFETY PRECAUTIONS
The HEMOTHERM has internal self-diagnostics that could prevent the equipment from
operating improperly. The most serious of these are the Remove from Service (RFS)
alarms. The RFS alarms will require the equipment to be repaired immediately. They are
indicated by an “EE” on the Heat side temperature display and a number on the Cool side
temperature display. Too high of a temperature in the heat reservoir is also an RFS alarm
and will be indicated by the appropriate red LED indicator. All RFS alarms will be
announced by an audible alarm that cannot be muted.
High and low temperature limiting thermostats are preset at the factory and should
perform satisfactorily for the life of the HEMOTHERM unit. Except for refrigeration
component repairs, the repair and servicing of the HEMOTHERM unit requires no special
tools. However, no attempt should be made to perform any of the repairs or service
procedures outlined in this manual unless the proper skills and knowledge are
possessed.
If water is found leaking into or around the HEMOTHERM unit prior to or during the
operating procedure discussed here, immediately disconnect power to the unit and
correct the malfunction before proceeding.
Before performing any disassembly procedure, p
ress the power switch to the OFF/“O”
position and unplug power cord from receptacle.
Exercise extreme caution if this equipment is used on electrically susceptible patients
(probe, catheter or electrodes directly connected to the heart). Always test for current
leakage before returning unit to service. Additional warnings are expressed at
appropriate points in the manual.
See the Warnings and Cautions in the front of this manual.
