• Heats one gallon of water from 60°F to
130°F in approximately 10 minutes

• Simple operation- plug into any
grounded wall outlet

• Automatic safety switch

• Full one year warranty against defects

Caution

• Do not use in hot tubs.

• DO NOT COMPLETELY IMMERSE THIS PRODUCT IN WATER. The handle and power cord are
not designed to withstand boiling water. Always keep the handle and power cord out of water.

• Before use, inspect the heater for any excessive lime build-up, cracks in the heating element, or
other damage or wear. Discontinue use immediately if any aw is observed.

• Connect only to properly grounded, 120 VAC, Ground Fault Circuit Interrupter (GFCI)
protected outlet.

• Never operate this heater without the guard securely in place over the heating element.
If operated without the guard in place a re hazard will result.

• Always unplug this heater before you remove it from the water or before leaving it unattended.

• The silver-colored stainless steel tube contains a thermal-overload safety switch. Always be sure
this tube is tightly connected to the black heating element. If a gap occurs between this tube
and the heating element, a re hazard will result.

Operation

1. Place heater in a container designed to contain boiling water.

2. Fill container with water to cover heater shield; at least 8" deep.

3. Plug heater into a properly grounded 120 VAC Ground Fault Circuit Interrupter
(GFCI) protected outlet.

4. Unplug heater if water level drops below 6" or when not in use.

• NOTE: This thermostatically-controlled heater will heat water to boiling and is
NOT intended to de-ice water. Always use this heater with a container capable
of holding boiling water. Use of a metal container is recommended.

• The heater will continuously provide heat while the heating element is
immersed in at least 6" of water.

• If the water level drops too low, the heating element will AUTOMATICALLY begin
to cycle on and o to maintain a safe operating temperature. The heater will
continue to cycle on and o every few minutes until the water level is restored.

Maintenance

Periodically remove excess lime build-up from the heating element using a liquid lime

remover. A thick build-up of lime (greater than 1 /32" thick) may cause the heating
element to burst. This may send a dangerous amount of electrical current into the water.
