• Read Operation Manual before operating.

• At least every 20 minutes, 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 physician

promptly of any change, or if the patient’s temperature is not responding properly, or does not
reach the prescribed temperature in the prescribed time, or there is a change in the prescribed
temperature range. Failure to inform physician of the deviation may result in injury to the
patient.

• 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 that may result.

• Do not place additional cold 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.

• Do not wrap pad so tightly as to constrict blood flow. Do not use pins to secure pad or

hoses. Do not allow pad or hoses to come in contact with any sharp object.

• Do not use the Electri-Cool® II system in the presence of flammable anesthetics. Risk of explosion
can result.

• The Electri-Cool® II system has been designed and tested according to UL-60601-1 and has passed
testing regarding the reception and emission of electromagnetic interference. However, operation of
the Electri-Cool® II system near sources of electromagnetic interference or near sources that may
receive electromagnetic interference may cause abnormal operation of this unit or other devices. If
interference of this type is observed, re-locate the unit away from such devices.

• Power interruption will cause the Electri-Cool® II 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.

• This device is still energized when the inlet switch is in the off position. To completely
disconnect the device from the power source, remove the appliance plug from the back of the

WARNING

Page 3 of 27

CAUTION

• Use distilled water only. Failure to use distilled water may result in poor performance and/or

damage to the Electri-Cool® II voiding the warranty.

• 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, the metal will begin to deteriorate and may
cause a leak in the system.

• Do not use alcohol. Alcohol may cause blanket deterioration.

• 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.

• Power cord has “HOSPITAL GRADE” plug (domestic units only). Grounding reliability can
only be achieved when connected to an equivalent receptacle marked “HOSPITAL
GRADE.”

• Do not operate pump without a 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 they are properly locked together.

• Make sure hose and pads are free of kinks that 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 and Hospital/Physician instructions for applying, storing, and disposal of
product.

4.0 Introduction

4.1 Purpose

The purpose of this manual is to provide operation and maintenance instructions for the Electri-Cool ®
II Cold Therapy Unit.

4.2 Clinical Indications
Cold therapy has been found to be clinically effective in accelerating the healing of damaged tissue,
and in retarding metabolism within the tissue cells.

Localized cold therapy is used in the operating room, recovery room, intensive care unit, physical
therapy, and in individual patient rooms. It is used effectively to treat surgical incisions, as well as
wounds and inflammation caused by traumatic injury. It is prescribed with many types of surgery, for
example:

• Orthopedic (Arthroscopy, Anterior Cruciate Ligament Repair, Arthroplasty for Hip, Knee, and other

Total Joint Replacement)

• Neurologic/Orthopedic (Laminectomy)

• Abdominal (Hernia, Cholecystectomy)

• Oral/Maxillofacial/Plastic (Dental Extractions, Rhinoplasty, Augmentations, Face Lifts)

• Urological (Vasectomy, Prostatectomy, Urological Implants)

• Obstetrical/Gynecological (“C” Section, Episiotomy, Hysterectomy)

In compliance with the Medical Device Directive 93/42/EEC

Page 6 of 27

In most cases, cold therapy is applied immediately following the surgical procedure directly to the
wound site. This acts to help reduce swelling and pain, while also helping to reduce or eliminate the
need for pain-killing medications. For the specialty of hand surgery, cold therapy is also applied to the
upper extremity before and during the procedure in conjunction with a tourniquet.

Other conditions indicating the application of cold therapy are:

• Acute injuries • Chronic pain

• Alopecia • Low back pain

• Arthritis • Muscle spasms

• Bruises/contusions • Sprains

• Cellulitis • Strains

4.3 Contraindications

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 or compromised circulation.

4.4 Description

The Electri-Cool® II Cold Therapy Unit 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 sub-assembly 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: 51ºF-55ºF (11ºC-13ºC); 46ºF-50ºF (8ºC-10ºC); and 40ºF­45ºF (5ºC-7ºC). In addition to the aforementioned features, this model includes audible alarms for low
temperature and low water with visual indicators. The unit also shuts down entirely in the event of an
internal component over temperature condition.

7.0 General Maintenance and Checkout Procedures

It is suggested you perform the following procedures in their order of listing and document the results on a
Preventive Maintenance Inspection Record. Refer to Table 7.0 for an example of an inspection form.

7.1 Exterior Physical Inspection

Look for cracked, bent, missing, or otherwise damaged parts. Carefully inspect the power cord for
cuts or exposed wire. Check the plug for missing or bent pins. Remove the fuse and make sure it is
the same type and rating as described on top of the unit.

7.2 Air Filter Inspection
Inspect filter before each use of unit. Remove air filter retainer to access the air filter on the bottom of
the unit. Inspect the filter for accumulated dust. If the filter is 30% clogged with dust, replace filter with
a new one and reattach the air filter retainer.

7.3 Flow Test

Maximum flow rate is obtained with water temperature at room temperature and the pad laying flat on
a smooth surface. If no flow rate is observed, check for kinks in the pad or hose, clamps closed on
pad, or couplings not properly seated and locked together, or reversed connections to the pump.
Allow water temperature to reach room temperature, and check flow rate with a flow meter. If the flow
rate is substantially less than 38 LPH (10 GPH), check the pump and/or pad/hose for restrictions.
See Trouble Shooting Guide.

7.4 Temperature Test
Set Temperature to the coldest setting, 5-7°C (40-45°F). Let pump run 60 minutes to allow internal

operating temperatures to stabilize before performing this test. Insert a digital Thermistor (series 400)
probe into the outlet water flow stream. Note temperature every 30 seconds for five minutes, (10
readings). Record the average of these readings. The readings should fall within the selected
temperature range on digital readout. Temperature swings should not exceed ± two degrees
Fahrenheit out of the selected range.

7.5 Low Water Switch/Alarm Test
To perform this test, first open the reservoir access lid. Reach into the reservoir to the float switch
and push the float all the way down to it lowest possible position. The low water alarm should sound
along with the illumination of the low water level LED located on the membrane control panel. The
unit will stop pumping water and stop cooling immediately. Release the float and let it gravitate to its
highest position. The unit should now resume normal operation.

Page 16 of 27

7.6 Leakage Current Test
Connect ground lead clamp of leakage current tester to the ground lug on the back of the unit. Plug
unit into tester. Test unit in all combinations of power switch off and on, normal and reverse polarity,
and normal and open ground. Record highest reading. If more than 50 microamperes, refer to
Troubleshooting Guide. Disconnect current leakage tester set-up. Unplug power from the unit.

7.7 Ground Continuity Test
Using an ohmmeter, measure the resistance between the ground lug and the ground pin of the power
plug. This value shall not exceed 0.2 ohm. If higher than 0.2 ohm, see Troubleshooting Guide.

7.8 Internal Heatsink High-Limit Thermostat Test/Redundant Internal Heat Sink -Limit Thermal
Fuse Test

Locate J4 connector on control board. Remove connector. Unit should alarm.

7.9 Water Temperature Low-Limit Thermistor Test
With a decade box insert connector to the low limit thermistor connector on control board, while
continuing to close the thermostat and thermistor. Set the resistance on the decade box to 2.22°C
(36°F). The low limit alarm should sound along with the illumination of low limit LED on the membrane
control panel. The unit will stop pumping water and stop cooling immediately. Reset the resistance on
the decade box to 2.78°C (37°F). The unit should no w resume normal operation.

7.10 Internal Physical Inspection
While the side enclosure is removed, carefully inspect the unit for any signs of leaks, loose
components, or damage. Check wiring for breaks in insulation, exposed wires, loose connections, etc.
Repair or replace components as necessary and retest unit before placing back into service. Once
inspection is complete, replace enclosure. Note: screws for enclosure are to be tightened to 10 in-lb
of torque. Run unit long enough to assure that all connections have been properly made and the
pump is in good working order.

SUGGESTIONS FOR PROTECTING THE RESERVOIR FROM BACTERIA

If sterile water is used and changed monthly, there should be no problem with bacteria forming in the reservoir or
blanket(s). If hospital procedures require the use of a bacteriostatic or bactericidal agent, we suggest Hospital­Approved Bactericidal Agents which are non-acidic and non-foaming.

NOTE: Do not use De-Ionized or Reverse Osmosis Processed 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.

SUGGESTED DECONTAMINATION GUIDELINES FOR

CINCINNATI SUB-ZERO EQUIPMENT

(Developed in conjunction with the risk management department at the Shriners Burn Institute in Cincinnati, Ohio)
Decontamination in the Healthcare environment is of the utmost concern with today's array of potential infectious

diseases. Cincinnati Sub-Zero has always been aware of these concerns in conjunction with the water reservoirs and
circulatory systems of CSZ equipment. For this reason, all CSZ equipment have a suggested monthly schedule for
flushing and cleaning the water system in an effort to inhibit the growth of bacteria and fungi.

The following decontamination procedure was developed to effectively rid the water system of all bacteria and not
damage any of the internal components of the equipment. All Steps should be followed as closely as possible.
This decontamination procedure should be conducted every three (3) months.

The Procedure:

1. Drain the water reservoir of your CSZ unit as described in Operational Manual

2. Flush the unit three (3) times per the following procedure.

A. Add one (1) ounce (30 cc) of household bleach (sodium hypochlorite) to the empty water

reservoir.

CAUTION

It is strongly suggested that appropriate eye protection and gloves be worn when handling and using
bleach. Wearing an apron is also suggested to protect clothing.

B. Fill the reservoir with warm tap water.
C. Turn the unit on and circulate per the chart below.

UNIT MODE TEMPERATURE DURATION

Electri-Cool II Cooling 5-7°C (40-45°F) 5 Min.

D. Drain the unit after each flush.

3. Rinse the unit three (3) times as described in (2) except to omit the household bleach (sodium

hypochlorite).

4. After the third rinse, drain the unit and add 22 ounces (650 liter) of distilled water to the water

reservoir and circulate.

5. Check the water with "Fac-Chek" pH strips or other appropriate test method for detecting bleach. If

bleach is detected, repeat steps 2 B, C, and D.

6. Once no bleach is detected, add the appropriate amount of U.S.P. Grade Propylene Glycol to the

water reservoir per the following chart:

UNIT U.S.P. GRADE PROPYLENE GLYCOL PER UNIT
Electri-Cool II 1.5 ounces (45 cc)

7. Continue to fill the water reservoir with distilled water.

8. Document the maintenance of the unit.

9. The unit is now ready to be placed back in service.
