Heat the liquid Thermo-Pad in hot water before using and then
activate.
Pre-heating the pad does not change the maximum temperature of the pad
but will dramatically increase the duration of the heat. When using the
pad immediately after recharging, wrap the pad in an extra layer of
towel.
You can have the benefit of the heat as the pad cools as well as the
extended
heat by activating the pad while it is still warm. In this way a model
818 can provide heat for up to six hours. Remember that the pad will
not appear to activate if it is above 130° F (54° C)
OUTDOORS IN COLD WEATHER
When using the pad outdoors in the winter, store it under your
clothes
as close to your body as possible. In this way the pad will be kept
warm
to achieve maximum heat when activated. The warmer the pad is when it
is
activated, the longer it will stay hot. Thermo-Pads will activate on their own if they are frozen. If this
occurs, the pad must be recharged before use.To avoid this
always
storethe pad where it will not freeze.
STORING THE THERMO-PAD
Always store Thermo-Pad in its liquid state. If you leave the pad in
its activated state for extended periods, water evaporates from the pad
making it more concentrated. This higher concentration is indicated if
in its liquid state there are white crystals in the pad. This
evaporation
can be reversed by immersing the pad in simmering water for extended
periods
and leaving it in the water to cool. This process may have to be
repeated
but will eventually return the pad to its original condition. The pad
will
continue to work even with the crystals in it but will form harder
crystals.
Preheating the pad before use will improve its performance.
