Installing the heater in the JUWEL filter system
The JUWEL aquarium heater is supplied with the heater holder (fig. 1) which you will
need for the installation.
Please perform the following steps for all JUWEL Aquarium filter systems:
(You may need to start by removing an installed separation wall holder.)
1. Install the heater holder.
2. Attach the heater to the filter housing on the inside of the filter and/or initially
insert the heater holder into the guide rail of the separation wall.
The heater is properly positioned if the heater holder rests on the upper edge of the
housing and/or the separation wall.
The heater is now operational.

Recommendation:
The JUWEL automatic heater warms the water of your aquarium up to 28°C
depending on a nomal room temperature of 21°C. If you keep your aquarium in
rooms below this or your fish need a higher temperature, we recommend to
purchase a second heater.
Safety instructions:
Only connect the heater once the aquarium is filled with water at least to the
minimum water level of the heater.
Never use the heater outside the aquarium.
Operate the heater indoors only.
Operation of the heater
The JUWEL aquarium heater is an essential component of the JUWEL filter system. Its
positioning within the filter housing and consequently in the water stream facilitates
even warming of the water in the aquarium.
You control the temperature of the water via the adjusting knob in the heater head.
You may specify the temperature the heater is supposed to heat the water to in
accordance with your individual requirements. The centre position between "+" and "-"
corresponds to a water temperature of approximately 23 - 26 degrees Celsius or 74-78
degrees Fahrenheit.
Please note that depending on the starting temperature of the water in the aquarium,
it may take approx. 12 hours and longer until the heater has heated the water to the
desired temperature. After that, the heater will automatically keep the water at the
desired temperature and switch on or off, accordingly. You recognise the operation of
the heater via the red glow light.
We also recommend you to check the temperature of the water by means of a
thermometer at regular intervals. The heater does not require further care or
maintenance.
Recommendation
JUWEL Digital Thermometer 2.0
To monitor the temperature we recommend the JUWEL Digital Thermometer (Part No.
85702). Available from your JUWEL Aquarium retailer.
Safety instructions:
Always unplug the heater and allow it to cool before removing it from the filter.
Never attempt to open or repair the heater. Any signs of damage or malfunction
and the heater should be replaced with an original JUWEL Aquarium heater.

heater.
Once removed never place on a flammable surface.
