AUTO-FILL WATER BOILERS INSTRUCTION MANUAL MODELS COVERED WB3 WB7 WB15 WB5E 1
IMPORTANT HEALTH AND SAFETY INFORMATION PLEASE READ BEFORE USING YOUR NEW WATER BOILER Your new water boiler is designed to provide a constant source of near boiling water for the preparation of hot drinks. THIS IS VERY HOT All personnel must be provided with sufficient and appropriate training in the safe use of this appliance. An instruction sheet displayed next to the machine is often helpful in notifying users that the appliance contains and dispense near-boiling water.
INTRODUCTION Your new water boiler is designed to give years of trouble free service provided that the instructions contained in this manual are followed carefully. Your new boiler is energy efficient, simple to operate and easy to service. It is recommended that the installation is carried out by a properly qualified fitter. CHECK LIST Before starting installation, check that you have the following parts: 1. 2. 3. 4. 5.
WARNING: THIS APPLIANCE MUST BE EARTHED REAR ENTRY OF CABLE Fixed or flexible cable to be connected direct to the terminal block, cable gland not utilised. BOTTOM ENTRY OF CABLE Use the cable gland. Loosen cable-gripping nut. Pass cable through gland, leaving enough free cable to connect into the terminal block. Tighten cable gland grip nut.
BOTTOM ENTRY Connect to a suitable cold drinking water supply using 15mm copper pipe and push on the ‘T’ piece supplied. The ‘T’ has been blanked off using a brass plug. Leave this plug in place. Push the ‘T’ piece firmly onto the water inlet solenoid pipe with the brass plug facing forward. Then push the 15mm cold water supply firmly into the bottom of the fitting. To avoid damage to the unit, do not use any solder connections whilst pipes are connected to the boiler.
OVERFLOW PIPE REAR ENTRY In your fitting kit you will find a straight push on connector with a small length of 15mm copper tube pushed into it. If rear entry has been chosen this connector must be replaced by a push on elbow (available from plumber’s merchants). Push the elbow onto the overflow pipe on the bracket (alongside the solenoid). The pipe must have a continuous fall and should not be longer than 200mm (if a longer run is required use 22mm pipe to avoid airlocks).
OPERATION (All models except WB5E) After the electrical and water connections have been made, switch the power and water supply on. The power and ready lights will flash once. The power light will then be constantly illuminated to indicate mains supply. Providing the water supply is present, the machine will start to fill. If the machine does not fill to its pre-set level within 4 to 5 minutes the red service light will flash 6 times. If this happens, check that the water stop valve is turned on.
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.
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.
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.
Clean the level sensing probes and their white holders completely using a clean non-metallic scourer. Ensure all traces of de-scaler are removed before using the boiler again. Rather than frequently de-scaling the machine, it may be preferable to install an effective scale reducer or WRC approved food quality water softener.
SERVICE WARNING LIGHT (All Models except WB5E) All models except WB5E have this facility. This light is designed to help you discover the cause of any malfunction. If the circuit senses a problem, the service light will flash a number of times and then pause and repeat this sequence. Count the number of flashes between pauses and refer to the table on the back cover.
