• Make sure that the heater is plugged in and the water's flow respects the indication of the
arrow on the heater's body
• Make sure that the difference between the set temperature and the room temperature falls
within the range given on the table (6).
• Ensure that your aquarium tank has the same size as described in the HEATER package
• Make sure that there is water flow through the HEATER
• Make sure that the water circulation is adequate, and that there are no deposits or foreign
bodies within the heater. Pull out the heater plug and remove any obstruction with a brush (5).
ATTENTION: do not use solvents or detergents of any kind to clean the heater, only warm
water.
