OPERATION AND MAINTENANCE
The water heater is ready for use once it has been connected to water and power. By
turning the thermostat knob on the front side of the protective cover, water
temperature can be set between " " frost protection position and " " approx. 75
°C
position. We recommend that the knob be set to position " ECO " as this ensures the
most economic operation of the water heater. This way the water temperature is
maintained at approx. 35 °C by (GT 10 and GT 15) and approx. 41 °C by (GT 5). The
operation of the heater at this temperature level also results in reduced build

up of
calcium and lime, as well as reduced heat loss than is the case at higher
temperatures. Due to safety reasons you can optionally set the highest temperature
value of water in the heater. Proceed as follows:
a) Insert screwdriver in slot 1 and remove button cover 2,
b) Set knob limiter 3 to any desired temperature value,

The operation of the heating element is indicated by the
light indicator that stays on until the temperature in the
tank has reached the set level or until the heater has been deliberately switched off.
When the water heater is not in use for longer periods of time, it should be protected
from freezing by setting the temperature to " ". Do not disconnect the power. Thus
the temperature of the water in the tank is maintained at about 9
°C. Should you
