SAFETY PRECAUTIONS
CAUTION
Read, understand, and practice the precautionary and operating instructions. Know the
limitations associated with the Heating Unit NGL-LJE-1. 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 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 Heating Unit on and off. Try to collect the interference using one or more of 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 us for help.
Do not use accessories other than those supplied with the Heating Unit or recommended by us.
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 71℃-74℃. The temperature of the water should be checked with a thermometer after every
adjustment, before using the hot pack. Always allow sufficient time for the water temperature to
stabilize
The 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 hot packs to avoid burning or scorching of the
packs.
Never allow the hot packs to dry after use.
Check the water level daily as it has a natural loss due to evaporating.
Clean the tank periodically as described in the maintenance portion of this manual.
Check the unit periodically for signs of leaking and contact service if leaks are noted.
Always replace Heating Unit hot packs 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 Heating Unit while filled with heated water. Tipping over could result in
burns to the users or others.
Always unplug the Heating Unit from power source before attempting to empty water from
unit.
Always use factory suggested replacement parts.
Always destroy and replace the hot pack which are exposed to contamination: hazardous or

cleaning materials, bodily fluids, mold, etc.
This unit should be operated, transported and stored in temperature between -40 ℃ to
+70 ℃ and no requirements for atmospheric pressure, with relative humidity ranging from
10%-100%.
Treatment time should not exceed 30 minutes.
DO NOT retrieve hot packs from tank or replace hot packs in tank with unprotected hand.
Avoid direct contact with mounting rack in tank.
Always wrap hot pack with towel or terry cover before handling or applying to patient.
Constantly monitor hot pack application to ensure that the skin is not becoming too hot.
Damage to skin can occur from exposure to extreme hot 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 hot packs.
DO NOT use hot packs directly over cuts, abrasions or wounds.

SAFETY PRECAUTIONS
WARNING
Grounding the Heating Unit NGL-LJE-1. Make certain the unit is electrically grounded by
plugging into a hospital grade electrical outlet with a ground terminal receptacle. Follow the
National Electrical Code.
The water temperature in the Heating Unit is approximately 71℃, and the water scalding
temperature is approximately 49℃.
Care must be taken when operating the 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 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
Specification of this manual.
Use only accessories that are specially designed for the Heating Unit.
Periodically inspect unit for signs of damage and pitting during regular cleaning intervals, as
described in maintenance portion of this manual.
DO NOT apply hot pack directly to skin.
Individuals with circulatory problems should consult with a physician before using this
product.
DO NOT sit or lie on the hot pack.
