What does the indication E-1 to E-8 on the display of my external heater mean?
As already described in the operating instructions, E stands for Error and indicates an error in the operation of the JBL PROTEMP external heater. Here you can see how each message can be easily solved. _x000D_ _x000D_ E-1: Cause: Water temperature is at least 1 °C above the set temperature. Solution: Regulates itself when water temperature drops. _x000D_ E-2: Cause: No water or air bubbles in the heater. Solution: Ensure that the heater is positioned as vertically as possible and that there is sufficient water flow. _x000D_ E-3: Cause: Electronics defective. Solution: Can only be fixed by a specialist. _x000D_ E-8: Cause: Temperature above 93°C. No water flow, or the inside is too soiled.

Where should you install the external heater?
First place the JBL PROTEMP e In-line heater on the outlet side of the external filter, before positioning the UV-C units, CO2 diffusers and other attachments. If this is not possible, you can still install the heater after the UV-C unit, but then only install diffusers behind it.

What water pressure are the PROTEMP e in-line heaters designed for?
This device may only be used for heating aquariums in the private area. For this purpose, the in-line heater is connected to an external filter or a feed pump. These systems are unpressurised systems which only use the principle of circulation and do not build up any pressure, as the inlet and outlet also provide an additional drain and the impeller does not build up any water pressure when pumping. The use of accessories or parts not recommended by the manufacturer can lead to hazardous situations and a loss of warranty. Installations on pressure pumps or directly on water pipes are therefore not possible._x000D_ _x000D_

Are PROTEMP e external heaters also suitable for marine aquariums?
The JBL PROTEMP e300 and e500 are external heaters for freshwater aquariums and are not intended for use in marine water, as salt crusts, caused by splashing water, can stick to the outside of the filter tank in marine aquariums. This can damage the display and other external components.
-
Does the alignment of the external heater matter during its installation?
Yes, because temperature measuring requires constant contact with the water. When installing, please pay attention to the flow direction marked by arrows on the heater housing. Attach the heater to the suspension loop provided for this purpose in a position as vertical as possible with the flow direction pointing upwards. This is the only way to ensure that the device is vented and that the temperature measuring functions properly.
