Important
To insure safety for both you and your animals It is essential that you read
and follow the Instructions carefully.
General Instructions
Caution: (1) have a qualied 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 by livestock, (3) do not use
extension cord, (4) inspect cord before using, (5) unplug heater at receptacle outlet
when not in use or before removing from tank, (6) store heater indoors after winter
season and (7) to ensure continued protection against shock hazard, connect to
properly grounded outlets only. Use ground fault interrupter in circuit.
PROTECTION FROM ANIMALS If you feel your animals are capable of chewing or
penetrating the power cord then it’s your responsibility to install this heater so the
animal will not be able to chew the power cord. You may accomplish this by
running the cord through a piece of pipe or conduit.
NEVER ALLOW MOISTURE TO PENETRATE YOUR ELECTRICAL CONNECTION If
you must use an extension cord make sure the electrical connection stays above the
snow or damp ground. Always wrap several layers of electrical tape tightly around
your electrical connection. If your moisture seal is not done properly there will be a
danger to both you and others - WE SUGGEST THAT YOU CONTACT AN ELECTRICIAN
TO MAKE SURE YOUR ELECTRICAL CONNECTIONS ARE SAFE FROM MOISTURE.
TO GUARD AGAINST FIRE DANGER NEVER OPERATE THIS HEATER WITHOUT
THE GUARD FASTENED TIGHTLY IN PLACE.
THIS HEATER HAS A BUILT-IN SAFETY THERMOSTAT
In the event this heater is removed or thrown from the water tank, the unit is
designed to shut-o before the heating element becomes hot enough to ignite a
re. If left energized the built-in safety device will gradually begin to cool- eventually
allowing the heater to begin to operate. The heater will “cycle” like this until it is
either immersed once again in water or the plug is pulled. Although the heater will
not be hot enough to ignite a re it will be hot enough to burn your hand or possibly
scorch the surface it is lying on.
This safety thermostat should be regarded as an emergency back-up, therefore; you
should install this heater so it will not come in contact with combustible materials.
Maintenance
Do not allow lime or other impurities (e.g. iron, mud, sh waste etc.) in the water to
build up on excess of 1/32” on the diameter of the tubular heating element. This is
an allowance of 1/64” on each side. An excess build up can cause the heating
element to burst, sending electric current directly into the water. The frequency of
cleaning depends directly upon the composition of your water supply (e.g. lime and
iron content).
Remove these deposits with ordinary household vinegar or a lime-removing
compound found in any hardware store.
DO NOT OPERATE WITHOUT GUARD IN PLACE.
- After you have removed the guard soak the heating element in a shallow pan
containing the vinegar (usually one to two days) and then remove the deposits
being careful not to damage the heating element.
- If you need to soak the heating element for a period longer than 24 hours - be sure
to replace the “old vinegar” with “fresh vinegar”. This is necessary to maintain the
“lime removing strength” of the vinegar.
- During the heating season EMPTY and rell your container on a regular basis. This
will prevent the build-up of dissolved lime in your water which is caused by
evaporation.
