SAFETY PRECAUTIONS Hydrocollator®Heating Units
Read, understand, and practice the precautionary and operating instructions. Know the limitations associated with the
Hydrocollator SS, SS-2, E-1, E-2, M-2, and M-4 Heating Units. Observe the cautionary and operational decals installed on the
unit.
DO NOT operate this unit in an environment where other devices are being used that intentionally radiates electromagnetic
energy in an unshielded manner. Portable and mobile RF communications equipment can affect Medical Electrical
Equipment.
The Hydrocollator Heating Unit generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to other devices in the vicinity. However, there is no
guarantee that interference will not occur in a particular installation. Harmful interference to other devices can be determined
by turning the Hydrocollator Heating Unit on and off. Try to correct the interference using one or more of the following:
reorient or relocate the receiving device, increase the separation between the equipment, connect the equipment to an
outlet on a different circuit from that which the other device(s) are connected and consult the Chattanooga Group Service
Department for help.
Do not use accessories other than those supplied with the Hydrocollator Heating Unit or recommended by Chattanooga
Group. The safety of other products has not been established, and their use could result in injury to the patient.
Never adjust the thermostat too high. The thermostat is extremely sensitive and the slightest adjustment will alter the
temperature several degrees. The recommended operating temperature is 160° F to 165° F (71° to 74° C). The temperature of
the water should be checked with a thermometer after every adjustment, before using the HotPac. Always allow sufficient
time for the water temperature to stabilize.
The Hydrocollator Heating Unit should not be installed above a surface that is susceptible to casual water damage.
Always keep the water level over the top of the HotPacs to avoid burning or scorching of the packs.
Never allow the HotPac to dry after use.
Check water level daily as it has a natural loss due to evaporation.
Clean the tank as described in the maintenance portion of this manual.
Check unit periodically for signs of leaking and contact service if leaks are noted.
Always replace Hydrocollator HotPacs as soon as they show signs of wear.
If the unit is to be left unattended for a period of time, unplug the unit, remove the packs, empty the water, and clean the
tank.
Do not move the Hydrocollator Heating Unit while filled with heated water. Tipping over could result in burns to the user or
others.
Always unplug the Hydrocollator Heating Unit from the power source before attempting to empty water from unit.
Always use factory authorized replacement parts.
Always destroy and replace HotPacs which are exposed to contamination: hazardous or cleaning materials, bodily fluids,
mold, etc.
This unit should be operated, transported, and stored in temperatures between 0° F and 140° F (-18° C and 60° C) and
atmospheric pressure range between 50 kPa - 160 kPa, with relative humidity ranging from 10% - 100%.
Treatment time should not exceed 30 minutes.
DO NOT retrieve HotPacs from tank or replace HotPacs in tank with unprotected hand.
Avoid direct contact with mounting rack in tank.
Always wrap HotPac with towel or terry cover before handling or applying to patient.
Constantly monitor HotPac application to ensure that the skin is not becoming too hot.
Damage to skin can occur from exposure to extreme heat or cold. Note instructions for proper use.
DO NOT apply over insensitive skin or in the presence of poor circulation.
Never lay or sit on top of the HotPac.
DO NOT use HotPac directly over cuts, abrasions or wounds.
Consult health care professional before using HotPacs on non-communicative individuals.
Exercise extreme caution when using HotPacs on non-communicative individuals.

•Grounding the Hydrocollator SS, SS-2, E-1, E-2, M-2, and M-4 Heating Units: Make certain the unit is electrically grounded by plugging
into a hospital grade electrical outlet with a ground terminal receptacle (U-ground outlet). Follow the National Electrical Code.
•The water temperature in the Hydrocollator Heating Unit is approximately 60° F (71° C), and the water scalding temperature is
approximately 120° F (49° C).
•Care must be taken when operating the Hydrocollator Heating Unit adjacent to or stacked with other equipment. Potential
electromagnetic or other interference could occur to this or other equipment. Try to minimize this interference by not using other
equipment in conjunction with it.
The Hydrocollator Heating Unit should be placed on a smooth, level surface. The surface should support up to the Filled Weight (weight
of heating unit filled with water) found in the Technical Specifications pages 8-10 of this manual.
•Use only accessories that are specially designed for the Hydrocollator Heating Unit. Do not use accessories manufactured by other
companies on the Hydrocollator Heating Unit. Chattanooga Group is not responsible for any consequence resulting from using
products manufactured by other companies. The use of other accessories or cables may result in increased emissions or decreased
immunity of the Hydrocollator Heating Unit.
•Periodically inspect unit for signs of damage and pitting during regular cleaning intervals, as described in maintenance portion of this
manual. Contact service if any signs of damage are discovered.
•DO NOT apply HotPac directly to skin.
•Individuals with circulatory problems should consult with a physician before using this product.
•DO NOT sit or lie on the HotPac.
•DO NOT add chlorine additive to water.
•DO NOT allow HotPac to come in contact with hydrocarbons (e.g., Comet®, Soft Scrub®, etc.).

NOMENCLATURE Hydrocollator®Heating Units
WHITE LAMP, when illuminated, indicates that main power is connected, the switch is on and
unit is operating.
RED LAMP (M-4 units), when illuminated, warns of an overheat/low water condition. Action is
necessary to correct the condition.
IMPORTANT: Some models (M-4 units) are fitted with a thermal cut-out thermostat which
acts as a “non self-resetting” thermal cut-out. In the unlikely event of a fault condition, this
device is designed to open the power circuit between 190° F ± 14° F (88° C ± 8° C). It is not
possible to alter its operating range. The operation of the unit may be restored by depressing
the red button after the water/element temperatures have been allowed to cool. If the fault
condition persists, please contact Chattanooga Group or an authorized agent.

SETUP Hydrocollator®Heating Units
Remove all of the contents inside the Hydrocollator Heating Unit and then replace the wire
rack. Make certain the drain valve is closed before filling the tank with water. The tank should
be approximately 3/4 full with packs removed. The tank may be filled from any standard type
faucet.
Check the voltage rating on the serial decal plate which is located on the back of the unit. To
turn the unit on, simply plug the unit into a 120 Volt~, 60 Hz outlet as indicated on the decal
plate. To turn the unit off, simply unplug from outlet. Do not attempt to use direct current.
Follow the procedures indicated in the Precautionary Instructions. Do not attempt to use the
unit if it is not properly grounded.
OPERATION
The Hydrocollator Heating Unit is simple and easy to operate. The controls are located in the
rear, near the bottom of the unit. The thermostat controls the temperature of the water. It is
located near the bottom of the unit on the control panel. It has been tested and preset at the
factory to normal operating temperature. If further adjustment is necessary, it can be easily
accomplished by turning the adjusting screw located on the thermostat. Turning the outer
screw counterclockwise lowers the temperature, while turning it clockwise raises it.
NOTE: Do not turn the inner stem under any circumstance! Stem is preset by the
manufacturer.
The Hydrocollator Heating units operate through the use of a hydraulic capillary-type
thermostat and can be left plugged in and turned on to provide a ready supply of heated
HotPacs .
The HotPac rack accommodates different sizes and types of packs.
SS Unit – Includes eight Standard Size packs. Special rack holds two Neck Contour packs.
SS-2 Unit – The unit comes complete with eight standard HotPacs.
E-1 Unit – With the insert in, the rack accommodates four Standard Size packs.
E-2 Unit – The E-2 unit comes complete with two Oversize, three Standard Size packs, and
one Neck Contour pack.
M-2 Unit - The M-2 unit comes complete with 12 standard HotPacs.
M-4 Unit - The M-4 comes complete with 24 standard HotPacs.
