Installation Instructions:
Check device for damage.
Remove transit protection.
Fix suction cups to double suction cup holder and clip onto heater (not near the heating spiral).
Mount thermostatic heater with double suction cup holder vertically in the aquarium, fixing it in a place where water flow is brisk (filter outlets/vents).
Set temperature.
Plug into electrical outlet.
Setting temperature
Turn the temperature selector ring to the desired temperature.
Monitor the aquarium water temperature using an accurate thermometer for at least 24 hours and make any necessary adjustments to compensate for calibration errors.
You should periodically monitor your aquarium water temperature with an accurate thermometer (Red light = heater in operation).
Note: The temperature selector ring should only be used as a guide. Always use an accurate thermometer for water temperature measurement.
Recalibration
If, after a day or two in operation the setting scale does not correspond to the water temperature, refer to the following procedure to recalibrate the heater:
Switch off the heater and unplug it from the electrical outlet.
Measure the water temperature with an accurate thermometer.
Turn indicator arrow (red) point to the measured temperature.
Set the desired tank temperature with the temperature selector ring (blue).
A sharp drop in water temperature is extremely stressful to fish and can compromise their immune system. Improperly sized heaters may not be able to maintain their set temperature and cause aquarium temperature to fluctuate several degrees per day.
Temperature can be the single most important component in the life of your fish. Fish, in the wild and in our aquariums, are very sensitive to changes in temperature. Learn the affects of water temperature on fish health.
Please note: Return of electrical equipment to Drs. Foster & Smith for exchange or refund is limited to 60 days from the date of purchase. Beyond 60 days, please contact the manufacturer for repair or replacement as covered by the manufacturer's warranty.
