Instructions for Utility/Bucket/Birdbath De-icers Models DT250, BDT250, and DT500
Setup and Operation
Operation
Simply place the unit into the water
that you wish to keep de-iced. Connect
the cord to a properly grounded, GCFI-
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.
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 has a non-
stick coating 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.

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
back of this sheet for instructions on
the LOCKNDRY cord.
Troubleshooting
The de-icer has been fully tested and is
guaranteed to perform to specifications;
there are no user adjustments or
modifications on the unit. However,
you can perform certain checks for the
following conditions:
If Frost Forms Around The Rim
Even in sub-zero temperatures, water
will evaporate. As it does, frost may form
around the edge slightly above the water
level. This is natural and since the frost
does not actually touch the water, it will
not be melted by the de-icer.
If Ice Forms
Check that you have power to the de-
icer by unplugging the unit and plugging
in an electrical device such as a lamp
or power tool. If no power is present,
check that a breaker has not been tripped
or a fuse blown. If the breaker or fuse
checks out ok, inspect the wiring to
the outlet, otherwise remove the unit
before resetting the breaker or replacing
the fuse and follow the instructions for
testing the unit with a GFCI as described
in the next section below.
If there is power present and the air
temperature has dropped rapidly, a thin
layer of ice may form before enough heat
can be added to the water to counteract
the drop in temperature. If, however,
the ice has not begun melting within 60
minutes, you should return the unit to the
place of purchase.
To Test The Unit With A CFCI
The de-icer may be tested by placing it
into a freezer for 15 minutes and then
immediately plugging it into a GFCI-
protected outlet. The unit should turn on.
For further testing the unit can be placed
in water before it is plugged in. If the unit
turns on and does not trip the GFCI, it is
operating properly. If you have questions
regarding its operation, please contact
Allied Precision at [phone] or
[phone].
If The Animals Are Being Shocked
Test the unit with a GFCI as noted above.
If it is operating properly then the source
of the shock is coming from a voltage
on the ground wire from your electrical
system. You should consult an electrician
or contact Allied Precision for assistance.
Caution
1. Have a qualified electrician install
a properly grounded receptacle
outlet, acceptable for outdoor
use and protected from snow and
rain, immediately adjacent to the
location where the heater will be
used.
2. Route the supply cord and locate
the heater so as to be protected
from damage.
3. Inspect the cord before using.
4. Do not use extension cords.
Approved for use only with the
API LOCKNDRY detachable power
supply cord.
5. Unplug the heater at receptacle
outlet when not in use or before
removing from tank or pond.
6. Store heater indoors after winter
season.
7. Connect to properly grounded
outlets only.
8. Connect only to a ciruit that is
protected by a Ground Fault
Circuit Interrupter (GFCI). This is
a sensitive device that cuts off the
electricity if there is any leakage
of current. This device may be
obtained from any electrician or
hardware store.
