WARNING

 A physician’s order is required for setting temperature and use of equipment. At least every

20 minutes, or as directed by a physician, check the patient’s temperature and skin condition

of areas in contact with the blanket. Also check blanket water temperature. Pediatric,
temperature-sensitive patients with vascular disease, surgical patients, diabetics and

patients with Raynaud’s Disease should be checked more frequently. Notify the physician
promptly of any change, in order to avoid serious injury.

 Observe patient’s skin condition frequently due to individual differences in sensitivity

and susceptibility to injury from cold and/or externally applied chemicals or pressure.
Patients at greatest risk are those unconscious, on prolonged therapy, diabetics,
children and persons incapacitated or with insensitive skin areas or poor circulation.

 Prevent excessive and/or prolonged tissue pressure and shearing forces, especially over

bony prominences to prevent skin damage which may result.

 Do not place additional heat or cold sources between the patient and blanket. Skin damage

may occur.

 The area between the patient and the blanket should be kept dry to avoid injury to the

patient.

 Do not use pins to secure pad or hoses. Do not allow pad or hoses to come in contact with

any sharp object. A water leak could cause a slip hazard.

 Do not use the Electri-Cool® II system in the presence of flammable anesthetics. Risk of

explosion can result.

 Power interruption will cause the Electri-Cool® II system to revert to the default range of 40°F

- 45°F (5°C - 7°C). Follow instructions for First Time Set-Up/System Test Routine to resume
operation. Failure to resume the desired therapy could result in injury.

 In order to avoid the risk of electric shock, this equipment must only be connected to a

supply main with protective earth.

 Electric shock hazard may be present. Do not remove cover.

Service is to be performed by qualified personnel only.

CAUTION

 US 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.

 Do not overfill. Overfilling may result in overflow when the water in the blanket drains back

into the system when it is turned off.

 Use only hospital grade power plug, or electrical shock may result.

 Do not operate pump without pad connected or with pad clamps in the “closed” position.

Always check clamps to make sure they are fully open.

 Check hose couplings to be certain that they are properly locked together.

 Make sure hose and pads are free of kinks which might restrict flow.

 Complete folding of pad may restrict flow and reduce therapy to patient.

 The pad surface should be checked for damage prior to each application.

 To ensure maximum therapy is delivered, it may be necessary to retain the pad on the

patient with straps for adequate contact with the patient.

 Follow pad instructions as well as hospital/physician instructions for applying, storing and

disposal of product.

 Special precautions regarding electromagnetic compatibility are required and the Electri-

Cool® II needs to be installed and put into service according to the electromagnetic

compatibility information provided. Electromagnetic compatibility refers to electronic devices
unintentionally affecting the operation of each other by emitting electromagnetic energy.

 Due to electromagnetic compatibility, other equipment can affect the Electri-Cool® II system.

The Electri-Cool® II should not be used adjacent to or stacked with other equipment. Other
equipment includes ventilators, patient monitors, anesthesia delivery equipment, etc. If
adjacent placement or stacking is necessary, the Electri-Cool® II and the other equipment
should be observed to verify that it is operating normally in the mode that is set.

 If the Electri-Cool® II system or 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 the specifications section for recommended separation distances between other
equipment and the Electri-Cool® II system.

 For safe handling and use of chemicals, follow manufacturer guidelines for cleaning.

 Always drain the Electri-Cool® II to a sanitary drain because bio-contaminants may be

present in the unit’s water supply.

1) RECEIVING AND INSPECTION/ IMPORTANT SAFETY INFORMATION

After unpacking the Electri-Cool® II, inspect the system for concealed damage. Retain all packing material
and carefully record or photograph any damage. Notify the carrier at once and ask for an inspection (in
writing). Failure to do this within 15 days may result in loss of claim. Do not return the equipment to
Cincinnati Sub-Zero. Call our Medical Technical Service department for further instruction.

2) INTRODUCTION

a) General Safety Precautions

To provide the patient with maximum safety during the use of the Electri-Cool® II Cold Therapy 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,
nurses, technicians and operators, must read and understand this operation and technical manual as well as
all precautions and warnings prior to use. It is recommended that this manual be read at least semi-annually
as a refresher for safe operation and application. For proper knowledge and understanding, in-service is

available upon request.

b) General Product Description

The Electri-Cool® II system has been designed to provide maximum thermal transfer efficiency at optimum
safety. The Electri-Cool® II consists of a plastic reservoir for holding distilled water; a float switch to sense
water level; a pump for circulating water through an external pad; a thermoelectric (TE) module to cool the
water; a microprocessor-based electronic control to regulate water temperature; and a fan to transfer
absorbed heat to the ambient air. The user can select among three pre-set temperature ranges: 51°F - 55°F
(11°C - 13°C); 46°F - 50°F (8°C - 10°C); and 40°F - 45°F (5°C - 7°C). In addition to the aforementioned
features, this model includes audible and visual indicators for low temperature and low water levels. The unit
also shuts down entirely in the event of an internal component over-temperature condition.

c) Intended Use

The Electri-Cool® II, Model 767 Portable Cold Therapy Unit is used to provide cold therapy immediately
following the surgical procedure at the wound site. The system is composed of a water reservoir, a
thermoelectric sub-assembly, a circulating pump, a micro-processor control board, a fan and a local therapy
pad.

d) Contraindications

There are currently no known contraindications.

e) Transporting and Shipping

Drain all water from the reservoir before shipment or storage. The Electri-Cool® II can be transported
through normal shipping methods via ground, air, or water when packaged in its approved packaging
material. During transportation and storage, packaging should not be exposed to conditions that fall out of
the ranges below:

I. Temperature: -40°C to 70°C (–40°F to 158°F)

II. Humidity: 10% to 100%

III. Atmospheric Pressure: 500 to 1060hPa (7.25 to 15.37 PSIA)

OPERATION AND TECHNICAL MANUAL ELECTRI-COOL® II, MODEL 767

CAUTION

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.

3) SET-UP/OPERATION/CLEANING & STORAGE

a) Equipment Set-Up

I. Before use, check the air filter for accumulated dust. If filter is dirty, replace it with a new one.

Refer to, “General Maintenance and Checkout Procedures”, for filter replacement instructions.

II. Check to ensure that the water level in the reservoir is at its maximum level. The maximum level

is at the lowest level of the fill spout (or threaded neck). Refer to “Filling Instructions”.

III. The Electri-Cool® II should be placed on a secure, flat surface at least 61cm (2 feet) from any

wall or object that may restrict airflow to the unit. A bed bracket or universal stand as listed in
“Accessories” section can also be used within proximity of the patient such that the attached
hoses will reach the desired therapy site.
