INSPECTING THE THERMALATOR
Inspection Checklist
ŸIs the Thermalator free of excessive wear?
ŸIs a properly-grounded and voltage-matched
receptacle available?
ŸIs the outlet equipped with a functioning GFI?
This Whitehall product has been carefully packaged at
the factory to minimize the possibility of damage during
shipping.
— Inspect the contents for damage.
If there is visible damage to the instrument upon receipt,
inform the shipping company and Whitehall immediately.
— Inspect the packaging for external signs of
damage.
WARNING
!
Do not attempt to operate this equipment if there is
evidence of shipping damage or you suspect the unit
is damaged. Damaged equipment may present
additional hazards to you. Contact Whitehall technical
support for advice before attempting to plug in and
operate damaged equipment.
WARNING
!
1- Take the Thermal Pack by the corner loops - one
white and one blue or black - so the sections are
horizontal.
2- Gently shake the pack back and forth to evenly
distribute the filler material.
Presoak thermal packs (Critical, if not presoaked
properly, the tank may develop surface rust
during use). Inspect the packs for any tears and
damaged or loose threads before starting the presoak
process. If packs are damaged, do not use.
Before the first use, you must condition each Thermal
Pack.
Shake to distribute
the dry material

Small
Rack
Adapter
(Optional)
Your Little Therm uses many different sizes of Thermal Packs. For Half, Cervical or Myofacial sizes, a small rack adapter
is provided. For Standard, Knee/Shoulder, 10" x 18" and 10" x 24" sizes, use only the stainless steel wire rack provided.

Myofacial
Cervical Knee/Shoulder
10" x 18"
10" x 24"
Half Standard
The water temperature for normal operating conditions is about 165°F (74°C). The thermostat is very sensitive; even a
small adjustment can raise or lower the temperature several degrees. The thermostat has an adjustable temperature
range of 65°F (18°C) to 175°F (79°C) ±5°F (-15°C). To adjust the temperature, you need a Thermometer capable of
180° F (83° C).
3- Periodic use:
Facing the back of the
unit, find the metal
temperature stem
between the 2 screws
in the lower middle of
the unit. Attach knob.
5Using the knob, turn clockwise to increase the
temperature. Allow the temperature to stabilize, and
measure the water temperature with the
thermometer.
CAUTION: Sensitive thermostat - a small adjustment
changes several degrees. Temperature range of 65°F
(18°C) to 175°F (79°C) ±5°F (-15°C).

CLEANING AND SANITIZING
MAINTENANCE
9
The Little Therm design is nearly maintenance-free. It
should, under most conditions, give many years of
reliable service. Clean and replace the Thermal Packs
as described below.
ŸHave a professional electrician thoroughly check the
following:
ŸSee Cleaning and Sanitizing
ŸAlways keep the Thermal Packs under water.
Replace any water that has evaporated.
1. Routine Maintenance (As Needed)
2. Monthly Maintenance
ŸDestroy or discard any contaminated Thermal Packs.
ŸClean wire rack and insert using mild soap. Rinse
thoroughly with clean tap water. Dry with soft cloth.
ŸScrub your Thermal Packs with warm soap and
water.
ŸKeep the pH (a measure of acidity of the water)
between 7.4 and 7.8 to reduce the scaling and
residue build-up.
ŸSee Cleaning and Sanitizing
3. Yearly Maintenance
ŸReplace worn out Thermal Packs. When The packs
begin to wear out, the non-toxic filler oozes through
the fabric and seams. The individual cells seem
empty. These packs don't hold the heat. Throw away
worn Thermal Packs.
1- Test for leakage current, dielectric strength, and
receptacle polarity and ground. If you need test
need test details, call the number listed on the
back page.
2- Check the power cord and plug. They should be
free of cuts, abrasion and other damage. Replace
the power cord assembly if it is damaged. Use
only factory replacement parts.
3- Remove the cover and check all electrical
components and connections. Replace any parts
that are in questionable condition. Use only
factory authorized replacement parts.
STORAGE
ŸSee Cleaning and Sanitizing
ŸPlace the Little Therm upright in a dry area away from
any chemicals.
ŸDry
2- Store in a dry area away from any chemicals.
2. Storing the Thermal Packs
2- Seal the bag.
ŸScrub your Thermal Packs with warm soap and
water.
1- Put the moist Thermal Pack in a plastic bag.
3- Store the bag in the freezer (recommended) or
refrigerator.
ŸMoist and Cold
1- Air dry the Thermal Pack completely in a well
ventilated area. The filler will become hard and
caked. This doesn't hurt the bags; more Pre- Soaking
time is then necessary.
1. Storing the Little Therm
Again, disinfection and sterilizing procedures are
different from facility to facility, and we have found that
alcohol is still the best (but expensive) cleaning and
sterilizing solution. Bleaches and iodine should not be
used.
Use of bleach or iodine will result in pin holes in the
stainless steel tank which will leak and void the warranty.
Cleaning of the tanks can best be accomplished with a
very mild, non-scratching household cleaner and a very
low abrasion plastic scouring pad lightly applied. On a
stainless steel tank, never use a metal scouring pad as it
is too abrasive and may leave carbon metal deposits on
the stainless, which will rust.
