Frequently Asked Questions - IWH850 N'oveen

What is the minimum water pressure required for the IWH850 to operate?

The minimum working pressure is 0.04 MPa. If pressure is lower, the heater may not turn on or the display may not light up.

Can I use the IWH850 with a shower head?

Yes, the IWH850 model includes a shower head with an adapter. To use, pull the adapter (Figure 3 in manual) to direct water to the handset; push to stop.

What should I do if the water temperature is too low?

If water temperature is too low, it may be due to high water pressure or low voltage. Reduce the water flow and check the voltage (should be 220-240V).

How do I clean the aerator?

Unscrew the aerator, rinse it under high-pressure water. If internal debris remain, use a needle to clear them. Always disconnect power before cleaning.

Is the IWH850 suitable for outdoor use?

No, the product is only suitable for indoor use. It must not be used in freezing temperatures, as the heater may be damaged.

How do I install the IWH850?

The heater can be wall-mounted or table-mounted. It must be installed horizontally to ensure the heating element is fully submerged. Follow the step-by-step instructions in the manual.

What does the LED display show?

The display shows the water heating temperature and the operating status (heating or not heating). Note: actual water temperature may differ from the display.

Why does the heater turn off the circuit breaker?

The circuit may be overloaded. Ensure the heater is on a dedicated circuit and not sharing with high-power appliances. Contact an electrician if the problem persists.

How do I clean the heating pipe?

Open the right end cover, gently clean the tube with a toothbrush, and rinse with water. Remember to disconnect the power before cleaning.

Can I use an extension cord?

No, do not use extension cords. The heater must be plugged directly into a grounded outlet with the correct voltage.

ROZWIĄZYWANIE PROBLEMÓW

Using in freezing temperatures* and incorrect assembly may result RISK in FIRE!

Remember!

The device must be mounted vertically and horizontally ** (depending on the model)

* During freezing temperatures in the room, especially in seasonal places such as summer houses, allotment gardens, disconnect the device from the power supply. The device cannot work in freezing temperatures.

** Due to the rapid heating of the heater to a temperature above 500°C, it is very important to install the device in accordance with the instructions (vertically and horizontally – depending on the model), so that the heater is completely immersed in running water.

• The product is only suitable for indoor use.
• When using for the first time, let the water drain first and then connect the electrical power supply.
• The outlet water temperature should be lower than 60 degrees Celsius
• Water outlet from the spout can not be connected to any additional nozzle, another tap or choke!
• The aerator should be cleaned regularly, the electrical power must be disconnected during cleaning, be very careful.
• To avoid danger, do not wash the electric battery under running water, use only a slightly damp cloth.
• The device must be disconnected from the mains each time in rooms where there is a risk of water freezing in the installation.
• Make sure that the heater is connected to a grounded outlet, otherwise do not use this device. Do not use extension cords to connect the battery.
• The heater requires a water pressure of 0.04MPa-0.6MPa.
• Set the knob to the cold water area for 5 seconds after each use, to avoid burning your hands the next time you use it, it can also effectively affect the extension of the life of the

heating element.

• If the power cord is damaged, replace the damaged cord by qualified personnel or a specialized service center.
• When using an electric heater, do not use other electrical devices connected in the same high-power electric circuit (eg air conditioning, induction cooker, electric kettle, etc.). The socket must not be connected to any other heavily loaded connections.
• This device is not intended for use by persons (including children) with reduced physical, sensory or mental abilities or with lack of experience and knowledge, unless supervision or instructions regarding use of the device by a person responsible for their safety have been given.
• Children should be supervised to make sure they do not play with the device

Preparations for assembly

Since the battery power is high, check the fuse. The maximum load of the fuse should meet the demand for the rated current of the battery.

Make sure that there is a ground wire in the base of the electrical outlet.

Before use, check that the actual voltage corresponds to the voltage marked on the battery. If you are not sure about these parameters, contact a person with electrical qualifications to verify the electrical installation.

Step-by-step installation:

1. Check if you have a safety valve in the water system, which should be in front of the battery, if you are unsure, contact the service or a person with appropriate permissions.
2. If the battery needs fixing (Figures 2 and 3), mount it as shown in the picture. Make sure it is fixed still.
3. Check that all connections are tight.
4. Turn the adjustment handle and let the water out, check the components for leaks. If there are no leaks, go to the next step - circuit installation.
5. Connect the heater to the power supply, fix the cable to the wall with a cable clamp (do not damage the power lin"e).
6. Turn the adjustment handle to the hot water area, the digital display will show the temperature - the water heating will start. Turn the adjustment handle to the cold water area, the display will go out - the water is not heated.
7. If you have any doubts, contact the service.

IMPORTANT!

In order to ensure the correct water level in the chamber with the heater, the device must be installed horizontally.

Method of use

1. Water temperature control handle

As shown in the figure, the lever has a rotation range of 150^ , the hot water area is 60^ , the cold water area is 60^ , the middle area 30^ is the lack of water. The battery operates on the principle of heating the flowing water, the higher the flow of water, the lower its temperature. Just move the lever gently to the hot water area and the battery will turn on, the flowing water will be heated up.

2. Use of water through a shower head

To use the handset in the shower mixer pull the

adapter (fig.3) and water from the battery will be directed to the handset. To stop the water, push the adapter.

3. Temperature display

The display shows the water heating temperature, and the battery operating status - heating / no heating. The temperature of the water itself may differ from the one shown on the display. Moving the lever into the cold water area will turn off the display.

4. Cleaning the aerator

Unscrew the aerator, rinse it under high pressure water, if you can not clean the inside of the aerator, use a needle.

5. Cleaning the heating pipe

Open the lid, gently clean the tube with a toothbrush, and then rinse it with water as shown in the figure below. Remember to disconnect the power before cleaning!

6. Pay attention to the correct horizontal positioning of the electric heater.

The battery must be mounted parallel to the tabletop, this applies to both the table and wall-mounted model.

TROUBLESHOOTING

Problem	Cause	Solution
The water does not heat up.	No power or water pressure is too low.	Check the power supply, the minimum pressure must not be less than 0.04MPa.
Water temperature too low.	The water pressure is too high or the voltage is too low.	Reduce the flow of water, check the voltage.
High water temperature, low water pressure at the outlet.	Inlet lock or low water pressure.	Check and remove dirt on the inlet filter, if the problem still exists, this means the water pressure is too low.
The temperature display does not light up.	Water pressure too low, circuit fault or faulty faucet.	Set the correct water pressure, check the circuit, contact the service.
During heating, the current fuse switches off.	Overloaded electrical circuit to which the heater is connected.	Contact an electrician.
