IMPORTANT
This product is approved for use only with the
LOCKNDRY® extension cord. It is not approved
for use with any other extension cords. The
plug on this product is specially designed
to mate with the LOCKNDRY® cord to form
a water-resistant seal. See the LOCKNDRY®
instructions at right.
OPERATION
Simply place the unit into the water that you
wish to keep de-iced. Connect the cord to a
properly grounded, GFCI-protected receptacle
while observing the cautions above. The unit
will turn on when the water temperature
approaches freezing conditions and will heat
the water 10 to 20 degrees Fahrenheit before
turning off.
Multiple thermostats within the unit monitor
water temperature as well as guard against
overtemp conditions. Please note: the unit
will not turn on unless the water temperature
is approaching freezing. If you wish to test
the unit, you must place it in a freezer for 15
minutes to get it cold enough to turn on.
WARRANTY
This de-icer is warranted for a period of 1
year from the date of purchase. If you believe
your de-icer is defective and still within the
warranty period, return it to the factory or
place of purchase for inspection and possible
replacement. The warranty is voided if (1)
the ground terminal on the plug has been
removed, (2) excessive deposits have been
allowed to accumulate on the heating element,
or (3) there is evidence of general abuse such
as animals chewing on the cord. This warranty
does not cover incidental or consequential
damage resulting from either a defect in parts,
materials, or operation failure. Some states
do not allow the exclusion or limitation of the
above damages so the above limitation may
not apply to you. No agent, employee, or
representative of Miller Manufacturing has any
authority to bind Miller Manufacturing to any
affirmation, representation or warranty directed
towards any products bearing the API name,
except as stated herein. This warranty gives you
specific legal rights--you may also have other
rights which vary from state to state.
MAINTENANCE
Do not allow lime or other impurities in the
water to build up on the heating element. The
frequency of cleaning depends directly upon
the composition of your water supply. The unit
is coated for easy cleaning. However, you may
wish to use lime-removing cleaners that can be
obtained at any farm or hardware store. Use a
soft brush for cleaning.
