HEATING D i ag ram ELEMENT HEATER L POWER PCB SOLENOID SOLENOID LOGIC PCB Inside Front Cover Operating Instructions General Product Description The SB is a wall mounted self calibrating and self filling boiling water heater It can be used for making cups of tea or coffee and even soups and hot snacks A special condenser traps steam and returns droplets to the tank minimising waste and saving energy The water temperature is set and automatically maintained by the SB and the unit is powered down with the Power button Water Is dispensed by rotating the front cover knob clockwise How to operate the SB O Make sure the electricity and water is turned on TEMPERATURE READY Refer to Fig 6 O Use the POWER button to switch the SB on and to power down The SB should be switched off at the mains if the water is not required e g at weekends holidays etc POWER light When the SB is on the POWER light will come on FULL light The FULL light comes on when the tank is full of water The SB fills up automatically and this can take up to 10 minutes if the tank is completely empty TEMPERATURE READY light The TEMPERATURE READY light comes on when the water is hot enough to use This can happen even when the tank is not completely full of water Please Note O The SB can take several minutes to reach the required temperature depending on usage and tank capacity O To avoid energy wastag2. still getting the water up to the boil See Table 3 on page 10 for approximate heat up times This is normal The tank is still filling itself with water and the heater is still getting up to the boil See table 3 on page 10 for approximate heat up times To avoid energy wastage the SB is designed to automatically reduce the temperature by 10 C if the unit is not used for more than 60 minutes The SB will automatically go back to boiling when the water is used Ensure that the electricity supply is switched on at the isolator then press the POWER button The water in the tank has been drained out due to a high demand Wait for the FULL amp TEMPERATURE READY lights to come on again When the SB is first switched on it can take up to 18 minutes to reach the Boil setting See Table 3 on page 10 for approximate heat up times Check that a pipe has been fitted to the steam vent Contact your installer if this is missing Use the POWER button to power down the unit and not the main electrical isolator This will reduce the amount of steam produced A new SB needs to be flushed out before being first used We recommend that the initial tank of boiling water is fully drawn off and discarded Wait for the FULL amp TEMPERATURE READY lights to come on before using the unit Scale has built up inside the tank As with all water heaters scale will build up inside the water tank How quickly this build up occurs will d
