ELECTRI-COOL Localized Cold Therapy Unit
1. Introduction
1.1 Purpose
The purpose of this manual is to provide operation, maintenance, repair, and service
instructions for the Electri-Cool Localized Cold Therapy Unit.
1.2 Indications—Localized Cold Therapy Equipment
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:
• Orthopaedic (Arthroscopy, Anterior Cruciate Ligament Repair, Arthroplasty for
Hip, Knee, and other Total Joint Replacement)
• Neurologic/Orthopaedic (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 most cases, cold therapy is applied immediately following the surgical procedure
directly to the wound site. This acts to reduce swelling and pain, while also reducing
or eliminating 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
1.3 Contraindications
Observe patient's skin condition frequently due to individual differences in
sensitivity and susceptibility to injury from cold or heat 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.

ELECTRI-COOL Localized Cold Therapy Unit
2. Description
2.1 Description
The Electri-Cool Unit 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
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.
A phone jack labeled “SKIN PROBE” allows connection of a 400 Series patient
temperature probe for monitoring and/or controlling patient skin temperature. The
control panel offers two modes of operation: “WATER TEMP” or “SKIN
TEMP”.
• In the “WATER TEMP” mode, the operator selects the desired water
temperature setpoint and the unit maintains the water at this
temperature.
• In the “SKIN TEMP” mode, the operator selects the desired skin temperature,
as measured by the remote probe, and the unit automatically lowers the
water temperature to maintain the skin temperature at the
setpoint.
• In the “WATER TEMP” mode the setpoint range is 40° to 68°F (4° to 20°C)
and in the “SKIN TEMP” mode the setpoint range is 50° to 86°F (10°
to 30°C).
Audible and visible alarms indicate “ADD WATER” and “LOW LIMIT”. Digital
displays indicate actual water temperature and skin temperature (when a probe is
connected) in degrees Fahrenheit or Celsius.
2.2 Accessories
The essential accessories for the Electri-Cool Unit are the Temp-Pad® or Maxi-
®
Therm
Lite Thermal Pads , Temp-Hose® Connection Hose, Steri-Probe® skin
probe and reusable cable.
The Thermal Pads consist of two layers of plastic sealed together to provide
multiple passageways for water flow in a random-flow pattern designed to
prevent occlusion.

3. Operation
CAUTION: Federal (USA) Law restricts this device to sale by or on
the order of a physician.
3.1 Theory of Operation
The Electri-Cool Unit provides a flow of temperature-controlled water to
an external pad. The unit, therefore, provides a means of cooling a
localized area of the body.
Two modes of operation are available to the operator: “WATER TEMP”
and “SKIN TEMP”. (See Fig. 3.1, Electri-Cool Control Panel.)
• In the “WATER TEMP” mode, the operator selects the desired water
temperature and sets the “SETPOINT” accordingly. The Electri-Cool
System then provides water at the “SETPOINT” temperature. To cause
a change in pad temperature, the operator must change the water
temperature setpoint.
• In the “SKIN TEMP” mode the operator selects the desired skin
temperature and sets the “SETPOINT” accordingly. The unit then
automatically provides water at a temperature necessary to maintain
the desired skin temperature.
Fig. 3.1 - Control Panel
Note: The “SKIN TEMP” mode requires the connection of a remote patient
temperature probe to sense skin temperature. If the probe becomes
disconnected, opened or shorted, an error code (“EEP”) will show in the
“SKIN TEMP” display and an audible alarm will sound.
Protection against overcooling is provided by a programmed low limit which
activates at 36°-38°F (2°- 3°C) and automatically disconnects power to the
thermoelectric unit and pump motor. In addition, if the water in the reservoir reaches
6
ELECTRI-COOL Localized Cold Therapy Unit
a low level, an alarm alerts the operator and power is removed from the pump and
thermoelectric unit. All alarms are indicated by visual and/or audible signals.
3.2 Safety Precautions
The Electri-Cool Localized Cold Therapy Unit has been designed to provide
maximum thermal transfer efficiency at optimum safety. Safety features include:
• Microprocessor control to ensure accuracy of temperature settings at all times by
eliminating the need for
calibration.
• Digital display of actual water temperature, setpoint temperature, and skin temperature (when a
probe is attached).
• Audible and visual alarms to indicate activation of programmed low limit at 36°38°F (2°- 3°C) (power to the cooling unit and pump motor automatically
disconnected)
• Audible and visual alarms to indicate disconnected, open or shorted temperature
probe.
• Audible and visual alarms to indicate a low water level in the reservoir (power to
thermoelectric unit and pump motor automatically disconnected).
CAUTION: Read the “Operation” portion of this manual before using
product. Water or skin temperature must be set as prescribed by
physician. 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
compromised circulation.
DANGER: Risk of explosion if used in the presence of flammable anesthetics.
CAUTION: Electric shock hazard. Do not remove cover. Service to be
performed by qualified service personnel only.
3.3 Filling Instructions
Remove reservoir cap and fill reservoir to full mark with distilled water only. Replace
cap.
3.4 Pad Connecting Instructions
Attach pad connecting hose to unit by inserting male couplings on 6 foot (1.83 meter) connecting
hose into female couplings on unit. Be sure couplings are locked together tightly. (An audible “click”
can be heard when couplings lock together.)
Select a CSZ Thermal Pad and insert the male couplings from the pad into the female
couplings on the hose. Again, make sure couplings are locked together tightly. The
hose and pad must be free of kinks that might restrict flow. Place or wrap pad onto
the area of the patient to be treated.

3.5 Remote Probe Connection
Place a skin temperature probe onto the patient as instructed by the attending
physician. Connect the probe to the reusable cable and then insert the plug end of the
cable into the jack on the side of the unit marked “Skin Probe”.
Note: Use only 400 series patient temperature probes.
3.6 Power Connection
3.6.1 Plug the power cord into a receptacle providing the appropriate voltage for your
unit. The Electri-Cool System is now ready to begin operation.
CAUTION: Minimum clearance of 2 inches (5 cm) air space must be
maintained on left and right sides of unit where cooling slots are
located. Restriction of air flow will reduce cooling performance and
cause unit to overheat.
3.7 Start-Up
Turning the power switch to the “On” position causes the following:
• Power switch illuminates and fan energizes.
• All visual indicators flash four times.
• The audible alarm sounds.
• The setpoint and mode of operation to which the unit was last set flashes four
times.
The purpose of this “test” sequence is to allow the operator to check for proper
operation of all indicators. The operator should make sure that all indicators are
operating each time the unit is turned on. If an indicator does not illuminate, remove
unit from service and repair.
3.8 Mode of Operation
Select the mode of operation desired by pressing the “WATER TEMP” or “SKIN
TEMP” switch on the control panel. The unit will always begin operation in the
mode to which it was last set, even if it has been unplugged. An amber indicator will
illuminate adjacent to the pressed switch indicating the mode of operation chosen. If
the “SKIN TEMP” mode is selected without a probe connected, the “SKIN TEMP”
readout will display an error code, indicating “EEP”, and the audible alarm will
sound.
3.9 Setpoint
Once the mode of operation has been selected, the setpoint may be raised or lowered.
To change the setpoint, press the “SETPOINT” switch (the display will flash) and
simultaneously press either the increment (up arrow) or decrement (down arrow)
switch. The “arrow” switches can only be activated while pressing the “SETPOINT”
switch. The “SETPOINT” temperature of the mode selected will display in the
respective window of that mode. Each time the unit is turned on, the setpoint will be
the temperature at which it was last set. Therefore, power interruptions will not affect
setpoint. The setpoint range is 40° to 68°F (4° to 20°C) in the “WATER TEMP”
mode, and 50° to 86°F (10° to 30°C) in the “SKIN TEMP” mode.

ELECTRI-COOL Localized Cold Therapy Unit
3.10 Continuous/Alternating Mode
The “CONTINUOUS/ALTERNATING" Mode allows for selection of either
continuous delivery of cold therapy or alternating cold therapy, i.e., the unit cycles
cooling on for 30 minutes and cooling off for 15 minutes.
3.11 Add Water
The “ADD WATER” indicator illuminates and the audible alarm sounds when the
water falls to a low level. Power to the cooling unit and pump is automatically
disconnected.
3.12 Cleaning
The Electri-Cool Localized Cold Therapy Unit case is constructed of plastic. Wipe
outer surface with a cloth soaked in a solution of water and mild detergent. Rinse
cloth of excess solution before applying to unit.
3.13 Storage
The Electri-Cool Unit may be stored full of water for short-term storage of one week
or less. If long-term storage is contemplated, it is best to drain the unit.
3.14 Draining
Drain the Electri-Cool Unit by removing the fill cap and inverting the unit over a
sink.
