OPERATION
BLANKETROL III, Model 233
OPERATION AND TECHNICAL MANUAL
Page 39 of 131
WARNING
Due to electromagnetic compatibility, the BLANKETROL III unit should not be used adjacent
to or stacked with other equipment.
Potential electromagnetic interference may result.
Other equipment includes ventilators, patient monitors, anesthesia delivery equipment, etc.
Electromagnetic interference refers to electronic devices unintentionally affecting the
operation of each other by emitting electromagnetic energy. Unit complies with IEC 60601-
1-2.
If the BLANKETROL III unit or the other equipment is not operating normally, remove the
device from service and have a biomedical or service technician observe the device in
operation. Refer to Section 7 for recommended separation distances between other
equipment and the BLANKETROL III.
Failure to do so may result in damage to the
BLANKETROL III system and patient injury.
Always
unplug the unit
before accessing internal components during service.
Failure to
unplug the unit could result in electric shock.
The repair, calibration, and servicing of the BLANKETROL III should be performed by qualified
Medical Equipment Service Technicians, Certified Biomedical Electronics Technicians, or
Certified Clinical Engineers familiar with good repair practices for servicing medical devices,
and in accordance with instructions contained in this manual.
Improper repair can result in
damage to the BLANKETROL III system and patient injury.
No modification of this equipment is allowed without prior, written authorization from CSZ.
Failure to do so may result in damage to the BLANKETROL III system and patient injury.
Before
returning the BLANKETROL III to patient use
after
repairs, the FIRST TIME SET-
UP/SYSTEM TEST ROUTINE in Section 2 must
always
be performed.
Improper repair and
inadequate maintenance can result in damage to the BLANKETROL III system and
patient injury.
CAUTION
Federal law restricts this device to sale by or on the order of a physician.
Use distilled water only.
Do Not Use De-Ionized water.
De-Ionized water
may cause
corrosion to plumbing system components.
Do Not Use Tap Water. Minerals and deposits
can clog plumbing system components.
Do not
use alcohol. Alcohol may cause blanket and unit deterioration.
Use only hospital grade plug or electric shock may result.
Do not
overfill. Overfilling may result in overflow when the water in the blanket drains back into
the system when the system is turned off.
Always drain the BLANKETROL III to a sanitary drain because
bio-contaminants
may be
present in the unit’s water supply.
Handling or use of the patient probe may result in damage from
electrostatic discharge
(ESD)
if proper precautions are not taken.
All wire-lead, patient-connected transducer assemblies are subject to reading error, local
heating, and possible damage from high intensity sources of RF energy. Inadequately
grounded electrosurgical equipment represents one such source, since capacitively coupled
currents may seek alternate paths to ground through probe cables and associated instruments.
Patient burns may result. If possible, remove the probe from patient contact before activating
an electrosurgical unit.
Do not
immerse probes or connecting cables in liquid. Failure to do so may result in damage
to the probes.
