Temperature regulation
The temperature is regulated with the knob (see Fig. 8).
FIG. 8
If the selected temperature is III, we recommend installing a temperature mixing valve to avoid
severe burns.
WARNING.
Do not operate the unit if the water inside is likely to be frozen.
VIII.- MAINTENANCE AND SERVICE
We recommend preventive maintenance once a year through a Calorex Service center.
WARNING.
Do not attempt to repair the water heater yourself. Call the Calorex Service center
telephone number for a technician to visit you. Disconnect the heater from the electric
current before carrying out any maintenance tasks or draining the heater. Otherwise, it can
cause property damages, serious injury, or even death.
Most of the maintenance tasks require emptying the water from the heater. To perform this
task, disconnect the electric current and remove the front cover.
