OPERATION & TECHNICAL MANUAL
The operator must read and understand the Operation & Technical Manual in its entirety
prior to operating the equipment.
Cincinnati Sub-Zero Products, Inc., reserves the right to make equipment changes and
improvements which may not be reflected in this manual.
This document may not be reproduced in whole or in part without written permission from
Cincinnati Sub-Zero Products, Inc.
Federal law restricts this device to use only on the order of a physician.
•Use distilled water only. Failure to use distilled water may result in poor
performance and damage to the Hemotherm unit.
•Do not use De-ionized Water. The majority of de-ionizers do not maintain a
neutral pH of 7. If the de-ionized water is acidic, it will cause a battery effect and
the copper refrigeration line will begin to deteriorate and cause a leak in the
refrigeration system.
•Do not use Reverse Osmosis (R.O.) water in a Hemotherm.
•Do not use alcohol. Alcohol may cause blanket deterioration.
•Do not operate without water to avoid damage to internal components.
•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.

• Do not use the Hemotherm system in the presence of flammable anesthetics.
Risk of explosion can result.
• Power interruption will cause the Hemotherm unit to revert to FILL MODE Follow
instructions for desired mode to resume operation.
Failure to resume therapy could result in serious injury or death.
The repair, calibration, and servicing of the Hemotherm unit 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 patient
injury and damage to the Hemotherm unit.
Before returning the Hemotherm unit to patient use after repairs, the INITIAL SET-UP
in Section 2 must always be performed.

IV
When warming blankets are used in conjunction with the Hemotherm unit, the
following applies:
• A physician's order is required for setting blanket water temperature and use of
equipment. At least every 20 minutes, or as directed by a physician, check
patient's temperature and skin condition of areas in contact with blanket; also,
check blanket water temperature. Pediatric, temperature-sensitive, patients with
vascular disease and operating room patients should be checked more
frequently. Notify the physician promptly of any change in order to avoid
serious injury or death.
• The method of temperature control provided by all hyper-hypothermia units
presents the danger of heating or cooling body tissues, particularly the skin, to a
point where they are injured, i.e., burns or frostbite, respectively. Depending on
the extent and severity of a burn, very serious and even fatal complications may
arise.
• Prevent excessive and/or prolonged tissue pressure and shearing forces,
especially over bony prominences, to prevent skin damage that may result.
• Do not place additional heat sources between the patient and blanket.
Skin damage may result.
• The area between the patient and the blanket should be kept dry to avoid injury
to patient.
