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)
Classified by Underwriters Laboratory Inc. ® with

Hazards only in accordance with UL 60601-1,
CAN/CSZ-C22.2 No. 601-1, 5R37
5R37

Page 7 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 40ºF-

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 17 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.
