Children should be supervised to ensure that they do not play with the electronic instant hot water appliance or instant hot water tap, a safety spring back is used to control the flow of the near boiling water for additional safety.
PLEASE READ ALL INSTRUCTIONS PRIOR TO INSTALLATION.
Installation
When installing the electronic instant hot water appliance, provide approximately 10cm to 15cm of air space on the sides of the unit for air circulation and approximately 2.5cm from the mounting wall.
The environment humidity should be in the range of 10% to 60%. Be sure there is no dew.
Do not power up the boiler tank until all pipework is complete and checked to ensure there are no leaks.
It is recommended that a qualified person installs this system.
Install the tap using the instructions provided with the tap.
Position the boiler tank in a suitable position close to the tap, ensuring that the silicone hose (10) can be connected without being stretched, restricted, or twisted.
Make sure the filter is fitted close to the boiler tank allowing space for a small amount of pipe between the filter and the boiler tank.
The boiler tank is fitted with a 3/8″ male thread for outlet and a 1/2″ male thread for the inlet. Fasten the 1/2″ Female BSP to 6mm Push Fit (6) to the to the inlet of the boiler tank (Blue). Do not over tighten as this will cause the washer to split and the system will leak.
Fasten the 3/8″ to Barb (8) to the outlet of the boiler tank (Red), making sure to include the washer (9). Do not over tighten as this will cause the washer to split and the system will leak.
The incoming mains cold & domestic hot water supplies should have isolation means and terminate with ½” BSP male threads, close to the tap flexible tails.
Fasten the Flexi Hose (Blue Stripe (Max 3Bar)) (1) to the incoming main cold with a wrench.
Fasten the Flexi Hose (Red Stripe (Max 3Bar)) (2) to the incoming domestic hot with a wrench.
Fasten the Flexi Hose (Blue Stripe (Water to Boiler)) (3) to the 1/2″ Male BSP to 6mm Push Fit (4). Ensure the hoses have no twists or kinks and do not overtighten when fastening.
The 1m PE Pipe (5) must be cut into two lengths before installation. The length will depend on your positioning of the filter and boiler tank. When cutting the PE pipe make sure there is no swarf in the pipe as this will restrict flow through the boiler tank.
You will need to run the first length of the PE pipe from the 1/2″ Male BSP to 6mm Push Fit (4) to the filter. Then run the other length of the PE pipe from the filter to the 1/2″ Female BSP to 6mm Push Fit (6) on the boiler tank.
To secure the PE Pipe into the push fit pieces, push into the hole until it stops. Then pull it to make sure it is fitted properly.
Attach the Pre-Installed Silicone Hose (10) to the Barb Fitting (8). Make sure the hose is snug around the fitting and secure by sliding the fixing clip (9) over the barb.

Priming
Before powering up the boiler tank you must first prime the boiler tank and make sure there are no leaks.
Open the isolation valves attached to the mains supply to allow water flow. Then press and turn the hot water handle on the tap until water beings to flow from the spout. This may take around 90 seconds. The water will not be hot as we haven’t supplied power to the tank yet. The boiler tank is now primed. Check all connections for leaks. If there is a sign of leakage make sure the connection has been tightened sufficiently. Press and turn the hot water handle again to ensure all leaks have been dealt with.
If you try to power on the tank before priming the display will read an `E3′ error message. This is because there is no water in the tank.
Powering On
Connect the plug to a nearby power socket and turn on at the switch.
Touch the illuminated, red on/off button
You should begin to see activity on the display of your boiler tank.
The left of the display will show the current temperature of the water inside the tank. The right of the display will show the temperature it is set to heat up to.
As a safety feature, the tank will not begin heating up until you chose a desired temperature by toggling the illuminated red `Set Temp.’ button until you reach the temperature you want. Available temperatures are, 75°C, 85°C, 90°C, 95°C or 98°C. This will only be required during set up or when it is powered on again.
Once heating has started the display will flash, the left-hand temperature will rise until it matches the set temp.
If you see an error message on the display `E4′ then please unplug and plug the boiler back into the power socket. If the issue persists, please contact the service centre.
If the tank is left on but has no water inside, then the boiler tank will automatically shut off after 5 minutes until it has been primed again using the instructions set out earlier.
When the water inside the boiler tank drops 2° below the temperature threshold, it will automatically begin to reheat the water till it reaches the set target.
If the electronic instant hot water appliance is not being used for long periods of time i.e.:
Over 7 days, to save power we recommend you switch off using “ON/OFF” switch. Prior to turning back on, operate the handle for 3 minutes to allow fresh water to flow through the system.
Over 14 days, follow the Environment guidelines and disconnect the tank.
Environment
The boiler tank must not be exposed to below freezing temperatures. If for whatever reason, there is a possibility of this happening you must drain the system of water. Shut off the mains and isolate the boiler tank system. Disconnect from the power supply and allow the tank to cool for at least 1 hour. Once cooled, disconnect the inlet supply and tip upside down into the sink to empty of water.
To reinstall, repeat installation instructions above.
You should regularly perform visual checks on the operation of the tank and look for any leaks in the system. If you find a leak you may either need to re-tighten the connections or replace any split rubber washers, silicone tubes, or flexi tails that may be causing the leaks.

PROBLEM CAUSE
Air Trapped Inside Filter
WHAT TO DO It is advisable to isolate the water supply to the 3 in 1 tap before commencing, prior to doing so fill a pouring jug with water (this will be needed at a later stage to prime the filter) The next step would be to remove the filter from its housing by twisting, have a cloth at hand to place under the filter housing to collect any excess water (the amount of water should be minimal) Hold the filter in the sink and slowly pour water into the top opening, as you are doing this, air bubbles will probably be visible, continue until the air bubbles disappear (1 litre of water should suffice, be sure to pour slowly) Keeping the filter upright slowly replace into the housing, twisting until the arrows line up. Turn the water supply to the 3 in 1 tap back on and test the flow, the problem should now be solved. It is advisable to operate taps slowly when first used after the water supply has been isolated, to avoid splashing from the mixture of air and water! Once the filter has been primed the problem should not return, due to the fact that the water heater has an internal expansion vessel to cope with the water temperature rise, on rare occasions air can be trapped which gradually makes its way to the filter. Generally, all air is pushed out of the system on the initial install or within 24hrs, but it is not uncommon for air to be trapped for up to several weeks.
