2. Mounting instructions

Environment

This device is delivered in sturdy packaging in order to avoid damage during transport.

This packaging is made of recyclable material. Please dispose the packaging in a responsible manner.

Disposal of the device

Old devices must not be disposed of in your household waste!

Every consumer is legally obliged to dispose of old devices separately from their household waste and to take them, for example, to a collection point in their local community or local district. Old electrical devices will usually be accepted free of charge. This ensures that the old devices are properly recycled and any negative impacts on the environment are avoided. This is why electrical devices are marked with the symbol shown on the left.

	InstallationThe device should be installed in accordance with the drawing on the first page of the user manual. Any other installation position may result in serious damage to the device.Installation should take place as close as possible to a cold water connection. The product should be protected from the effects of frost (for example in caravans, summer houses, etc.).
	When mounting swivels and compression fittings, always use 2 open-end spanners in order to prevent bending and twisting pipes and accessories.
	!	FrostIn case of risk of frost in a room, the device should not be installed in this room. If, despite this advice, the device is installed in a room where there is a risk of frost, the device should be emptied before the risk arises.
	!	The Hotto is not suitable for installation on a reverse osmosis installation or a water softening installation with pH reduction.
	!	Always use the Hotto safety group for connecting. Never use the device without a safety group!
	!	Use of a different tap than the supplied Hotto 3-in-1 tap, or a change in the tap/boiler combination, may damage the product. The warranty will always become invalid in case of incorrect installation or modification!
	!	Important: Never insert the plug in the earthed wall socket before the appliance is filled with water!
	!	Never connect the Hotto boiler to a hot water pipe. This might decrease the life expectancy of the boiler due to increased limescale build-up on the heating element and inside the mixing valve.
	Water qualityIn areas where the water hardness is above 12 °dH a water filter approved by Hotto must be placed in the supply water line. Failure in doing so will void the warranty. See www.hotto.com for more information and ordering options for water filters. The water quality must meet the following requirements:
	pH scale 7 - 9.5 pH
	Fe (Iron level) < 0.2 mg/l
	CI (Chlorine content) < 150 mg/l
	DH (German Hardness) < 12 °DH
	Minimum flow pressure 0.1 MPa

2A Connecting the tap

Step I: Connect the cold and hot water hoses (G) by screwing them in the tap.

Step 2: Place the tap in the hole ( 33 - 40 mm). The Hotto logo of the rosette (A) with rubber ring (B) should be pointing towards the front.

If the counter top is less than 35 mm thick, go to step 3a. Else, proceed with step 3b.

Step 3a: In case of a counter top less than 35 mm thick, first place the stability triangle (S), then the rubber ring (C) and finally the metal ring (D). Then tighten the nut (E) containing the two screws (F) by hand.

Step 3b: In case of a counter top between 35 and 65 mm thick, place the rubber ring (C) and then the metal ring (D). Then tighten the nut (E) containing the two screws (F) by hand.

Step 4: Tighten the two screws to fixate the nut (E).

Make sure the hoses are not installed with a kink or twist.

2B Connecting the installation set

Step 5: Close the main water tap. Then install the installation set according to the provided instructions, steps 6 to 9.

2C Connecting the boiler

Connection of the device to the power supply network must take place in accordance with electric installation standards and as specified by local laws and regulations. The device must be directly connected to the power supply network (230V) via the electrical cable and plug.

Avoid danger from damaged power supply cables. In the event of damage, the device must be replaced by the manufacturer or its customer service department, or by an equivalently-qualified person.

Ensure that the addition of this device will not overload the fuse protection in your mains. Internal modifications to the product may cause problems if this work is not carried out by authorized and qualified technical staff. The warranty only applies if the product has not been modified in any way, i.e. subject to it being in unchanged condition.

In order to avoid creating an unsafe situation by inappropriate resetting of the maximum temperature safety device, this unit may not be powered via an external switching device (a time switch for example) or connected to a circuit, which is regularly switched on and off by the power supply company.

Never place the Hotto boiler lying down or upside down. The boiler should always be upright, so that the switch (B5) is at the bottom.

Step 10: Connect the boiler's cold water supply hose (J) to the Hotto safety group.

Step II: Connect the tap's hot water hose (G1) to the boiler's hot water hose (G2). Then connect the tap's boiling water hose (H1) to the boiler's boiling water hose (H2) with the ring (N).

Stap 12: Insert the tap's cold water hose (L) in the compression t-piece in front of the safety group. Properly tighten the clamp nut of the t-piece using a suitable open-end wrench.

Stap 13: Place the insulation part (M) around the boiler's boiling water hose connection. Fixate the insulation with the accompanied tie wrap.

Then open the main water tap and the stop valve (O7) of the safety group. Fill the Hotto boiler with cold water by opening the boiling water knob until no more air is coming out of the tap. This may take a few minutes. After the boiler has been filled with water you must fully open the lever for hot water (K2). Allow the water to flow until no more air is coming out of the tap. Then insert the plug in the wall socket.

Important: In the unlikely event that the device is connected to the mains power supply without being filled with water, or if for some reason the device switches off after a short while, please disconnect the plug from the wall socket to allow the device to cool down. It may be necessary to reset the boiler: See the troubleshooter.

3. User instructions

The device must be filled with water before connected to the electrical supply!

The device should always be connected to a safety group!

Implementation (step 16)

The boiler is switched on with the switch (B5) on the rear, after the boiler has been fully filled with water. The boiler is now standby and is not yet heating. You will see that the LED at the front turns orange.

70° C setting (step 17)

Press the standby key (B3) once and the water will be heated to a maximum of 70^ C. The left blue LED will light until the temperature has been reached, after which the LED will turn red.

100° C setting (step 17)

Press the standby key (B3) once more, and the water will be heated to 100^ C. Now the right LED will turn blue and then red once the temperature has been reached.

Setting the temperature for hot water (step 18)

The hot water temperature can be adjusted by turning the round knob (B4) at the front of the boiler to the right (lower temperature) or to the left (higher temperature). The setting range is 35 - 70 °C, if the boiler is set to 100 °C. The setting range when the boiler is set to 70 °C is 35 - 60 °C.

Using the tap (step 14/15)

- Cold and hot water

With the lever (K2) in vertical position, the tap will provide cold water. You will only get hot water if the lever is moved towards the front. In this way no hot water and energy is wasted.

- Boiling water

In order to get boiling water you must first push in the catch (15.1) and then rotate the boiling water knob (K1) away from you (15.2). When you let go of the knob (K1), the built in spring will make sure that it will return to its original position immediately. This feature will prevent curious children from activating the boiling water tap by accident.

	If the water in the boiler is heated, the volume will increase. This is referred to as expansion water. The expansion water will drip away via the safety group. This is necessary and should not be prevented.
	If all the boiling water is used, it will take approximately 20 minutes for the water to reach the correct temperature. The LED on the boiler will turn red once all the water in the boiler has reached the set temperature.
4. Maintenance
	This device does not require any maintenance by the user. Professional maintenance should always be carried out by an expert.
	The safety group discharges expansion water through its funnel. This funnel must be placed in a continuous downward direction and must always be left open to the atmosphere. A discharge hose is placed between the funnel and sewer. This construction must always be placed in a frost-free environment.
	Check the functioning of the safety group by turning the large knob on the safety group once a year, allowing water to flow out, and closing it immediately. This will prevent the valve of the safety group from getting stuck. Also check the drain for blockages. If it is blocked, unblock the drain or instruct a third party to do so.
	If faulty, never try to repair the device yourself. Please contact the nearest service specialist or the party that supplied the device originally. See www.hotto.com
	CleaningThe housing of the device can simply be cleaned with a damp cloth. Do not use aggressive cleaners or cleaners with a scouring effect!
	Legionella preventionDo not use heated water as drinking water. After prolonged shutdown of the device for example due to holidays, the device should be fully heated up to the maximum temperature before re-using. It is recommended to flush the pipes for one minute.

5. Troubleshooting

Note: in case of problems, always consult the troubleshooter!

If the water in the device is no longer heated, first check whether the plug is properly connected to the wall socket and whether the fuse of the device group is still working. For all other failures, please consult the troubleshooter.

If the device no longer works because it was connected without being filled with water first, follow the troubleshooter. The device has been overheated and needs to cool down, or possibly repaired.

If the device has been reset several times, but still does not work, please contact the Hotto service line.

6. Disconnect and drain boiler

When the boiler needs to be disconnected follow these steps:

I. Put the boiler in standby mode by pressing the standby button (B3) until the standby LED turns orange.
2. Drain the boiling water with the boiling water knob (K1) until cold water comes out of the tap.
3. Turn off the boiler with the switch on the back side of the boiler (B5) and pull out the plug from the socket.
4. Close the stop valve from the safety group.
5. Relief the pressure from the boiler by opening the boiling water knob (K1) and warm water lever (K2) until no (cold) water comes out of the tap.
6. Now the hoses of the boiler can be disconnected. Please note that some water may come out of the cold water hose (H2).
7. Place the boiler near the sink.
8. Blow on the warm water hose (G2) from the boiler and the remaining water will flow out of the boiler through the cold water hose (H2).

It is likely that a small amount of water will remain in the boiler.
