Please clean the pane thoroughly before you install the thermometer. Algae, biofilms and lime can prevent it from sticking. If the thermometer still doesn’t hold, there may be a problem with the suction cup. Due to a material defect some suction cups have bubble-like excrescences which prevent a correct hold. If you own such a suction cup, please contact our customer service, and provide a photo.
JBL ProTemp Coolers cool the water temperature by 2-4 °C in high ambient temperatures. To achieve this with this product, it’s important the maximum recommended aquarium volume is adhered to. Please note that the cooling effect only occurs when the cooler is in operation and that the system needs to have been running continuously for a few hours beforehand. The air flow needs to be directed across the entire width of the aquarium and be at a 45° angle to the water surface. If only a part of the water surface is ventilated or the angle is set to 90°, the desired effect will be lost or greatly reduced. The housing can be rotated 360°.
The ProTemp CoolControl is connected between the power supply and the ProTemp Cooler. It is therefore not possible to connect two coolers to one controller. Each Cooler needs its own controller.
After reinstallation the bubbles move only haltingly through the diffuser and sometimes merge into large bubbles. The device needs approx. 48 hours to set up! After that a bio-film will have formed on the surface of the device, allowing the bubbles to rise freely upwards. After the running in time the required bubble count will adapt itself for your aquarium.
Yes, the CoolControl of the predecessor range can also regulate the new ProTemp Cooler x200 and x300 (generation 2) aquarium coolers.
The cross-flow fan provides an audible air flow that is uniform and must not rattle or clatter. However, if such a problem does occur, it could be an indication of damage from a fall or strong impacts on the enclosure wall. Check that the cross-flow fan is correctly mounted or if the housing is incorrectly assembled. If these are not the causes your ProTemp Cooler must be returned to the factory for inspection and repair by the JBL customer service.
The cross-flow fan of the cooler 200X or 300X conveys a large amount of air to ensure sufficient evaporation on the water surface and thus cooling. As with a room fan, this is not possible silently, but can be quiet. To ensure quiet operation, the fan is mounted with a ball bearing for smooth running. If loud noises should occur during operation, please check the fastening on the aquarium edge / base. The vibrations are probably transmitted to the base and can be eliminated by small changes. If you notice strong vibrations on the housing, this can be eliminated by turning the housing.
A lot of commercially available products, including our predecessor range, have two to four axial fans (depending on the model). The appearance is reminiscent of a PC fan. The design of the cross-flow fans used in the JBL PROTEMP COOLERS makes them run more smoothly and gives them a quieter air flow. Its one axis drive ensures a further reduction in noise. In models using similar technology, the bearing is typically based on sintered bushes. Thanks to a high-quality ball bearing, a dedicated bearing to give additional damping, plus a reworked bearing in the cross-flow fan wheel, the new PROTEMP COOLERS guarantee you greater stability. Rattling and squeaking are now a thing of the past.
