Setup and Operation
Specifications
Model 15N: 1500 watts, 120 VAC, 60 Hz
Model 10N: 1000 watts, 120 VAC, 60 Hz
CAUTION
1. To insure continued protection against electric shock, connect to properly grounded
outlets only.
2. Unplug the heater at receptacle outlet when not in use or before removing from
tank or pond
WARNING
1. Read all instructions.
2. Inspect the cord before using.
3. Do not use extension cords.
4. Do not immerse the plug.
5. Store indoors after winter season.
6. Connect only to a circuit 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.
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. To remove buildup, soak the heating element in vinegar or a lime removing
cleaners obtained at any farm or hardware store. Then use a non-metallic brush to
remove any remaining build-up. Inspect the element for any cracks before
reinstalling.
IMPORTANT
This product is approved for use only with the LOCKNDRY Listed Detachable
Power Supply Cord. The plug on this product is specially designed to mate with the
LOCKNDRY detachable power supply cord to form a water resistant seal. Mating
receptacles can be identified by the red locking nut on each cord. The back of this
sheet shows how the plug mates with the LOCKNDRY cord.
IMPORTANT
The use of the Model 88R guard is mandatory to prevent the heating element from coming into
contact with combustible materials such as the side or bottom of a non-metallic tank. See the
back of this sheet for instructions on attaching the guard.
Read and follow all instructions in this sheet.
Installation
1. If the unit is to be used in a non-metallic tank, a Model 88R guard must be
attached in order to prevent the heating element from coming in contact with the
walls of the tank. See back of this sheet for instructions on attaching the guard.
2. The unit should be placed in a tank with water and then plugged into a Ground
Fault Circuit Interrupter (GCFI) protected circuit.
3. Some animals--particularly horses--may try to remove the de-icer from the tank.
To prevent this from happening, you may wish to run the cord through PVC or
galvanized tubing extending over the tank or use the Model 23ST De-icer Safety
Tether fromAPI. Be sure to allow slack in the cord to compensate for varying
water level.
4. This de-icer is UL approved for use only with the LOCKNDRY detachabled power
supply cord--see back of this sheet for details. Do not use extension cords.
5. The unit is thermostatically controlled so that it will not turn on until the temper-
ature drops to around 40°F. If it is removed from the tank, it will turn on and then
shut itself off in about 60 seconds. It will then cycle on and off in this manner.

Warranty
This de-icer is warranted for a period of 12 months 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 cord has been modified in any way, (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
Allied Precision has any authority to bind Allied Precision to any affirmation,
representation or warranty directed towards any products bearing the Allied Precision
name, except as stated herein. This warranty gives you specific legal rights--you may
also have other rights which vary from state to state.

Troubleshooting
The de-icer has been fully tested; there are no user adjustments or modifications on the
unit. However, you can perform certain checks for the following conditions:
- The tank or pond freezes over:
Unplug the unit and plug 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 is ok, check the wiring to the outlet, otherwise remove the unit from the
tank before resetting the breaker or replacing the fuse and test the unit with a Ground
Fault Circuit Interrupter (GFCI) as described in the next section below.
If the de-icer is located far from the electrical breaker box, there could be a significant
voltage drop in the wiring to the outlet, which, in turn, could reduce the power output of
the de-icer. You should consult a qualified electrician if you suspect this is a problem.
If the air temperature has dropped quickly, some ice may form before the unit senses
the drop in temperature. If, however, the ice has not begun melting within 2 hours, you
should return the unit to the place of purchase.
- The livestock are being shocked:
If you suspect that the animals are being shocked, DO NOT TOUCH THE WATER.
Instead, unplug the unit and remove it from the tank. If the GFCI has tripped, return
the unit to the place of purchase. If it was not plugged into a GFCI outlet, you should
locate a GFCI to test the unit. (Most newer homes will have a GFCI in the bathroom.)
To test the de-icer, place the unit into a freezer for 30 minutes to make sure the
thermostat is on. Next, place the unit into water (eg. sink or bathtub), and--without
touching the unit or the water--plug the de-icer into the GFCI for 15 seconds. If the
GFCI trips, return the unit to the place of purchase.
If the GFCI does not trip, the unit is operating properly and the source of shocking is
most commonly due to a leakage of voltage to the ground circuit in the electrical
supply. Many times, this leakage is coming directly from the electric utility company.

Attaching the Guard to the De-icer
Turn the unit upside down and place the guard as shown. Rotate the short spring to
thread it onto the guard and the straight section of the heating element. The spring
should capture the cross-wire on the guard and be centered around the copper strap as
shown.
