Franke Instante 3-in-1 Boiling Water System

Installing the Instante 3 in 1 Kitchen Tap

Carrying out this operation first will make it easier to plan the layout inside the cabinet. For safety it is advisable to locate the tap out of the reach of smaller children.

1. The tap will require a standard 35mm diameter hole cut in the kitchen work surface. Important Note: before cutting the hole make sure that there is sufficient clearance between the hot/cold tap handle and the splash back when the handle is in the fully open position. ?
2. Insert the flexible hoses and the wire lead through the 35mm hole.
3. Position the tap for the owners' convenience. (The tap can be rotated 180° for left handed operation of the boiling water function).
4. Working inside the cabinet, slide the gasket (8) and the clamp plate (5) over the hoses and the two studs at the base of the tap. Screw the two clamp nuts (6) on to the studs using the box spanner (7).
5. Check the alignment of the tap then tighten the two clamp nuts using the box spanner to firmly secure it on the work surface.

Plan the Layout Inside the Cabinet

• Determine the best positions for the hot and cold mains water supply.
• Determine the best positions for the boiler and the filter unit, making sure that the boiler power cable, the flexible hoses, and the filter cartridge change indicator cable, are all within comfortable reach of their respective connection points without them being compressed, stretched or kinked.
• The boiler must be installed upright with the hose connections at the top, never on its side.
• Allow a minimum clearance of 80mm at the top of the boiler for the connecting hoses.
• Choose a location for the filter unit (20) and the stop valve (23) to allow convenient access for future filter cartridge changes.

The Plumbing

Important Note: Before installing the new tap it is essential that you thoroughly flush through the supply pipes in order to remove any remaining swarf, solder or other impurities. Failure to carry out this simple procedure could cause problems or damage to the workings of the tap. ?

1. Provide a hot and cold water supply for the tap. (We recommend that service stop-valves are fitted in both the hot and cold water supplies to the tap.)
2. Tee off the cold mains water supply to provide an independent feed to the water filter.
3. Install the stop-valve (23) inline on the independent feed to the filter. Important note: the ends of the stop valve are not the same. One end has an internal chamfer to connect to compression pipework; the opposite end has a flat washer face to suit the G1/2" (1/2" BSP) nut and washer of a flexible hose (refer to diagram (23) in component list.)
4. Connect the hot and cold G1/2" flexible hoses to the respective hot and cold supplies and tighten them firmly to make a watertight seal – two G1/2" NutRunna hand tightening devices (11) are supplied loose with the tap for this purpose. The tap hose with the blue indicator should be connected to the cold supply and the hose with the orange indicator to the hot supply.

Install the Filter Unit

Important note: The filter unit must be installed inside a cupboard. Long term exposure to direct light can degrade the plastic sump leading to eventual failure. ?

1. Position the filter unit (20) vertically with the hoses at the top, in its previously determined location.
2. Mark the positions for the two filter unit support screws (22) using the holes in the filter bracket as a guide.
3. Set the filter unit aside and screw in the two screws leaving the heads slightly proud (approximately 4mm).
4. Take the G1/2" nut (20.A) at the free end of the filter inlet hose (blue indicator) and screw it on the G1/2" male outlet thread of the stop valve (23). Hand tighten the nut firmly using the one of the G1/2" NutRunna® (11) sufficient to make a watertight seal. Do not overtighten.
5. Hang the filter unit on the two screws. If the panel is too thin to mount the filter securely strengthen the panel with a wooden batten.

Install the Plastic Vent Assembly

Important Note: The vent pipe must be installed vertically with the air-gap at the top and strictly in accordance with the instructions. The vent pipe conforms to the building regulations and on no account should be shortened or modified in any way. ?

To avoid debris blocking the vent and causing it to overflow do not, under any circumstances, install the saddle clamp on the U Bend, waste trap, side/underside of the waste pipe.

If the Instante system is being installed on a sink with a waste disposal unit, the Instante vent assembly must be installed on a separate waste pipe to the waste disposal unit.

Choose a convenient position to fit the saddle clamp (16) on a vertical section (Option 1) of the waste pipe, or alternatively on a horizontal section (Option 2). When installing the saddle clamp horizontally the elbow (18) is not required. Be careful to allow sufficient clearance for the height of the vent assembly and enough room to operate the pipe cutter (19).

1. Separate the two halves of the saddle clamp by unscrewing and removing the four nuts and bolts. Discard the two black rubber inserts for 41mm waste pipe. Leave them in place for 32mm pipe.
2. Place the saddle clamp in position on the chosen section of waste pipe and re-assemble the clamp. Tighten the nuts and bolts securely to make a watertight seal.
3. Insert the pipe cutter (19) into the saddle clamp and cut a hole in the waste pipe by rotating it to the right until it breaks through. (see diagram).
4. Screw the vent assembly (15) into the saddle clamp. When the saddle clamp is installed on a vertical section of the waste pipe screw the elbow in first and use the lock nut to secure the air gap assembly in the vertical position.
5. Take the vent hose (17) (black indicator) and connect the G1/2" nut end onto the corresponding G1/2" male thread at the top of the vent assembly. Use one of the G1/2” NutRunna® (11) to tighten the nut firmly, sufficient to make a watertight seal. Do not overtighten.

Install the Boiler

Important note: Do not plug the boiler into the power supply at this stage. ?

For ease of installation the boiler connections and the flexible hoses are colour coded:

• Green - Filtered water
• Red - Boiling water
• Black - Vent

1. Remove the protective caps from the three connections on the top of the boiler.
2. Place the boiler (12) in position upright on a flat surface inside the cabinet with the connections to the top.
3. Take the G1/4" female nut (20.B) at the free end of the filter outlet hose (green indicator). Carefully position one of the washers (14) inside the nut. Screw the nut onto the G1/4" male boiler inlet (green dot). Hand tighten using the attached NutRunna® sufficient to make a watertight seal. Do not overtighten.
4. Take the free end of the boiling water flexible hose (1.B) attached to the base of the tap (red indicator). Carefully position the remaining washer (14) inside the nut. Take the spare G1/4" NutRunna® (10) and place over the nut. Screw the nut onto the G1/4" boiling water outlet of the boiler (red dot). Hand tighten the nut firmly, sufficient to make a watertight seal. Do not overtighten.
5. Take the push-fit elbow (13). Connect the elbow to the grey push-fit stem on the end of the vent flexible hose with the grey plastic push fit stem (black indicator). Push the push-fit elbow firmly home in place onto the metal spigot (black dot) protruding from the top of the boiler.
6. Use the cable ties (9) to neatly secure the various flexible hoses out of harm's way.

Install the Filter Change Indicator Module

1. Choose a convenient location for the module, making sure that the attached power cable is within easy reach of the mating cable attached to the base of the tap.
2. Secure the module in place using the self-adhesive Velcro pad provided.
3. Plug the two cables together.
4. Install the 2x AA batteries (4) in the module (2). A “bleep” will confirm that they are correctly installed. The LED light on the tap will glow RED followed by YELLOW before turning off.

The LED indicator:

• Red - Indicates that the water filter cartridge needs replacing.
• Yellow - Indicates that the two AA batteries in the module need replacing.

Cleaning the Instante Tap

To maintain the appearance of this fitting, ensure it is cleaned only using a clean, soft damp cloth. A solution of warm water and mild liquid detergent may be used where necessary, and then the fitting rinsed thoroughly. Abrasive cleaners or acidic cleaners MUST NOT BE USED under any circumstances. Avoid contact with all solvents.

Changing the Batteries in the Filter Cartridge Change Module

If necessary separate the module from the Velcro pad and slide off the battery cover at the side of the module. Remove the battery carrier and replace the two old AA batteries with two new ones. Press the reset button.

Removing the Boiler

1. Disconnect the electricity supply to the boiler.
2. Operate the boiling water function and run the boiling water until the water flowing from the spout runs cold.
3. Shut off the water supply to the boiler.
4. Operate the boiling water for a second time until the water stops flowing to release the pressure in the boiler.
5. Disconnect the hoses from the boiler using a suitable container to catch residual water.
6. Remove the boiler carefully, unscrew the brass drain nut at the base and pour out the water it contains.

Water Filter Maintenance

• The water filter supplied with this unit is designed to both protect the boiler and remove sediment, chlorine and other potentially harmful contaminants.
• Changing the filter cartridge every 6 months will keep the boiler in good condition. Franke will not accept responsibility for boiler failures due to the build-up of lime-scale if the filter cartridge has not been replaced at the recommended 6 month intervals.
• The occasional wash in warm soapy water is sufficient to keep the plastic housing clean. Under no circumstances should the plastic filter housing come into contact with any proprietary cleaners such as kitchen sprays, bleach etc. as contact with certain chemicals can degrade the plastic and cause it to fail.
• The plastic housing must be replaced every 10 years due to the tendency of plastic materials to degrade and weaken over time.
• A smear of WRAS approved silicon grease applied to the filter sump thread and to the rubber sealing ring in the head of the filter at each cartridge change will make it easier to unscrew the sump. Only a WRAS approved alternative grease must be used for this purpose. Non-approved greases may degrade both the seal and the plastic housing and lead to eventual failure. Small tubes of WRAS approved silicon grease are available at www.frankefilterflow.co.uk.

Changing the Filter Cartridge

1. Operate the switch on the front of the boiler to switch off the boiler power supply.
2. Drain the system of boiling water by running the boiling water until it runs cold.
3. Shut off the water supply to the filter using the adjacent stop-valve.
4. Press the red button at the top of the filter unit to exhaust the pressure in the system. It will not be possible to unscrew the filter canister if this operation is not carried out.
5. Place a shallow container in the cabinet to catch any water residues when removing the filter sump. Grip the sump firmly and turn it firmly to the left to break the seal. Unscrew the sump by hand until it separates from the head of the filter.
6. If the old cartridge does not automatically fall free press down on the top mount of the cartridge to release it. Remove the old cartridge and discard the remaining water in the sump.
7. Remove the new filter cartridge from its packaging, wet the "O" seal and place it in the filter sump. Position the sump, with the cartridge inside, under the filter head and screw it in place. The cartridge should engage automatically. Tighten the sump, sufficient to make a water tight seal.
8. Turn the water supply 'on' and check the system carefully for leaks. ✔️
9. Operate the system and run the boiling water for a few moments until the water runs clear. Run the boiling water for a moment to release any trapped air.
10. Turn the boiler power supply back on. ?
11. Press and hold the reset button on the filter change indicator module for 5 seconds. The LED light on the tap will glow red, followed by yellow, and then the module will emit an audible beep. The filter change indicator is now reset.

Sensible Precautions

If you are planning to leave the premises for an extended period (over a week) it is a sensible precaution to turn off both the electricity supply and the water supply to your Franke Instante system.

The Boiling Water Flow is Agitated and Noisy ♨️

Please bear in mind that your Instante Tap system is dispensing boiling water, rather than very hot water, and as a consequence there will be the normal steam, agitation and noise associated with boiling water. Initially this may be alarming, but read through the technique suggested below and practice it a few times. Soon you will gain confidence and using the tap will be second nature. Bear in mind that your Instante tap dispenses water hotter than you are used to with a kettle.

To operate the boiling water function: Discharge a small amount of water until steam appears. Turn off the boiling water. Position the vessel over the outlet of the tap spout and continue to dispense boiling water by maintaining pressure on the handle. Gradually lower the vessel while keeping the spout just above the surface of the water.

Water Fails to Discharge from the Vent Tube after Power Has Been Switched On to the Boiler for 20 Minutes

Check there is power to the boiler. The ‘Plug' LED should be green. ?

Check there are no kinks in the vent hose.

Water is Continually Dripping/Running into the Vent Assembly

Water continuously discharging from the vent indicates that the water pressure is too high; above the 5 bar (73 psi) stipulated maximum. In normal operation the pressure relief valve will allow water to drip for approximately 20 minutes after the boiler is switched on. Thereafter it will drip periodically; after water is drawn off and as the boiler comes back up to temperature.

Check the water pressure at a low demand period (mid morning or mid afternoon). If it exceeds 5 bar (73 psi) it will be necessary to install a 3-4 bar pressure reducing valve. A suitable valve can be purchased at www.frankefilterflow.co.uk or from a plumber's merchant.

While waiting for the pressure relief valve to be fitted turn off the boiler and then shut off the water supply to the filter.

The Vent Assembly is Overflowing

Check that the hole has been properly cut in the waste pipe and if so that it is clear of any debris.

The Hot Water Flow from the Tap is Slow (Not the Boiling Water)

Check the Hot water pressure. A minimum of 1.5 bar pressure is required.

The Filtered Boiling Water Flow from the Tap is Slow

Generally this indicates that the filter cartridge is clogged with contaminants and needs replacing. You can check by operating the filtered water with no cartridge in the filter housing. ?

The Flow of Filtered Boiling Water has Slowed to an Unacceptable Level Inside the 6 Months Change Period

The period between cartridge replacements is not guaranteed; it is an estimate based on filtering mains water of average quality. Please bear in mind that water quality varies from locality to locality and situation to situation. In areas with higher than average turbidity (particle contamination) more frequent cartridge changes may be necessary.

The Boiling Water Function is Dispensing Cold Water Instead of Boiling Water

Check that the electrical supply is correctly connected. ✔️

Check the 13amp fuse in the plug.

Milky or Cloudy Appearance of the Boiling Filtered Water

A new filter cartridge has a significant amount of air trapped in the microporous structure of the cartridge. This will form tiny bubbles and give the water in the glass a milky appearance that will soon disperse when left to stand for a few moments. This may continue for 2 to 3 weeks until the cartridge is fully conditioned.

Tiny Black Specks in the Water

Tiny black specs may appear initially in the water. These are harmless particles of carbon; residues from the manufacturing process. Allow the filtered water to continue flowing for a while until they are completely flushed through.

Condensation is Dripping from Exposed Copper Pipes Adjacent to the Boiler

This can be reduced by wrapping insulation around the pipes in question.

Unsightly Deposits on the Surface of a Cup of Tea

In hard water areas a 'scum' can appear on the surface of hot tea. Although unsightly it is completely harmless. The cause is related to the precipitation of calcium and magnesium in hard water regions and a reaction with the tea bag material. Changing tea bags will often remedy the problem. Alternatively you can consider switching to a Franke 06 cartridge which will remove the calcium and magnesium however please note this filter will need to be changed more frequently, perhaps every 2- 3 months. The life of the Franke 06 is dependent on the hardness of the water supply and the volume of water passed through it, so is impossible to predict, however the return of the ‘scum' on hot drinks is an indication it should be replaced.

Foam or a Film is Forming on the Surface of Hot Drinks

This is caused by a combination of the agitation of the boiling water creating millions of tiny air bubbles, the ph of the water and the amount of oil in the teabag material. Experimenting with different tea bags is worth a try.

To reduce the problem try filling the teapot or cup with boiling water before dropping the tea bag in rather than running the boiling water directly onto the teabag or perhaps experiment with different brands of tea bag.
