In daily use, switch on and wait for the ready light to illuminate. The water will then be at the correct temperature and the boiler ready to use. We recommend that you switch the power supply to the boiler off overnight and when the unit is not in use. OPERATION (WB5Eonly) After the electrical and water connections have been made, switch the power and water supply on. When the power supply is switched on, the small indicator lamp on the front panel will glow orange. This means that the water is filling to the bottom probe. When the bottom probe has been reached, the indicator lamp will change to red to show heating. When the water has reached the correct temperature the light will change green. Wait a further 10 minutes before starting to use. Your machine does not fill completely at once. The water input is electronically controlled to obtain maximum output, temperature and efficiency. In daily use, switch on and wait for the green light. The water will then be at the correct temperature and the boiler ready to use. TEMPERATURE CONTROL & SAFETY CUT OUT A small knob protrudes from the base of the mounting bracket (Not WB5E). This controls the boiler temperature. It has been factory set at approximately 98oC and should not need adjustment. However, under certain conditions (extreme change in ambient room or cold water temperature), the boiler temperature may fluctuate slightly. The knob may then be used to adjust this. Using a screwdriver, loosen the transit bracket, which holds the knob in place. Turn the knob clockwise to increase or anti-clockwise to decrease the temperature. All models except WB5E Should the temperature be set too high, steam or boiling water will discharge through the overflow pipe. In the event of this happening, a high temperature control switch will switch off the heater. The red service light will flash 10 or 12 times depending upon the water level. Switch the boiler off at the electricity supply and switch back on a few moments later. This will reset the boiler but if it cuts out again it is recommended that you then adjust the temperature by turning the knob anti-clockwise. If the boiler continues to over-boil, contact the Instanta service department on 01704 502911 for advice. WB5E Should the temperature be set too high, steam or boiling water will discharge through the overflow pipe. In the event of this happening, a high temperature control switch will switch off the heater. After a short period, the neon indicator will change from green to flashing red or flashing red and green. Switch the boiler off at the electricity supply and switch back on a few moments later. This will reset the boiler but if it cuts out again it is recommended that you contact the Instanta service department for advice. CLEANING The external surface of the machine can be kept clean by wiping with a damp cloth. Do not use abrasive material on the outer surface of the machine. TECHNICAL SPECIFICATION ALL MODELS Tank constructed in stainless steel. Tank insulated from outer casing with high temperature polystyrene. All boilers have electronic control of the main functions. This means that the temperature is controlled precisely within given parameters. The circuit constantly monitors the operation of the machine and warns the user via the light if abnormal circumstances have been detected. If the light flashes, refer to the diagnosis codes. MAINTENANCE NOTE: After initial commissioning or subsequent re-commissioning (service-repair), check that the water supply has been established prior to switching on the boiler. The boiler should be periodically checked for scale build up. The frequency depends upon hardness of the water and whether or not an effective scale reducer is fitted. It is advisable to keep a spare tap spring (part no TP1007/L) and washer (part no TP1001/L) in case of emergencies. Apart from the removal of scale, no regular maintenance should be required. DE-SCALING All models except WB5E To de-scale your machine, first disconnect the machine from the power supply. Remove the case by removing the top and bottom screws holding the case to the wall bracket. Drain the remaining water through the drain plug in the bottom of the tank. Remove the boiler lid by unscrewing the fixing screws. The tank is now accessible. The whole boiler can be disconnected and lifted away from the wall fixing by removing the push on water and vent fittings and disconnecting the electrical components. However, it is recommended that only a qualified person undertakes this work and that unless a qualified person is available, the de- scaling is carried out with the boiler on the wall. Lift out the baffle plates on the inside of the tank (taking note of the position of the plates). Remove as mu...
