USE

4.1. Use
The filter inserts are used to soften cold tap water.
They reduce the lime content and carbonate hardness of tap water, which protect the steam generator from harmful lime build-up.
4.2. Structure
Tap water (A) flows into the filter insert (see Figure 3). The particles are removed in the pre-filtering of the part (E), while activated carbon removes unpleasant smells and flavours, such as chlorine, from the water. After this, lime is removed from the water with ion exchangers (F), and the water is treated with activated carbon (G) and filtered (H).
The filter system has an integrated by-pass mechanism that stops carbonic acid from being removed for a specified volume of water. This bypass water is only led through the activated carbon (G) and the particle filter (H). At the outlet (D), the tion-exchanged water and the by-pass water are mixed.
When the by-pass settings of the filter head are defined correctly based on the hardness and vo- lume of the water used, the filter will provide the equipment with water with optimal quality.
A. Water inlet from the water source
B. By-pass water flow
C. Filter head’s by-pass setting
D. Outlet for filtered water
E. Pre-filtering (particle filter, activated carbon)
F. Ion exchangers for lime removal
G. Activated carbon filtering; also filters the bypass water
H. Particle filtration; also filters the by-pass water

USE AND SAFETY

This section provides a general overview of all matters related to safety and operation to ensure safe and problem-free use. Even if all safety measures are taken, all products involve a degree of risk, particularly if the product is used or handled incorrectly. The guarantee is only valid if these instructions for installation of use have been followed in their entirety.
5.1. Appropriate use
The filter system is only designed to reduce the lime content of cold drinking water and to remove unpleasant smells, flavours and particles that may be present in drinking water. The filter is designed and produced solely for appropriate use as described in these instructions for installation and use. Any other uses will be considered inappropriate.
WARNING!

• Only cold water of potable quality can be used as incoming water for the filter system. Inappropriate use, such as using the filter with water that does not meet the requirements for potable water, causes a health hazard. This may pose a microbiological risk if the incoming water contains microbes. High heavy metal content or organic impurities in the water may also pose a health hazard.
• To ensure and protect the quality of drinking water, the national and local regulations must be followed in the maintenance and other work on the filter system.
• If water supply authorities or service providers order users to boil tap water before use due to microbial contamination or similar reason, these orders will also apply to filtered water. When the authorities announce that boiling the water is no longer necessary, the filter insert must be replaced and the system must be cleaned carefully, connectors and hoses included. Misuse may endanger your health.
• The filter head includes an integrated backflow barrier (DIN EN 13959 approved). If the filter system is used for equipment (such as industrial kitchen equipment) that requires special safety units, the appropriate safety units must be installed in addition to this integrated backflow barrier.
• Remove the filter system from the incoming water source before starting maintenance work on the water supply system. Rinse the water pipe carefully before installing the filter system.
• Before starting any work, remove all power sources from all devices connected to the system.

PLEASE NOTE!

• Inappropriate installation of the system may damage property. Follow the national and local regulations on installation, hygiene recommendations and technical standards to protect drinking water.
• Making unauthorised modifications or technical changes to the filter system is prohibited.
• Mechanical damage in the filter system voids the guarantee.
• The stop valve must be installed in the inlet of the filter system (not included in the delivery).
• If the product has been stored in a temperature below 0°C, it must be kept in its package in the installation temperature for at least 24 hours before handling it.
• The system must not be in contact with chemicals, solvents or fumes.
• The installation location must be protected against freezing and both direct and indirect sunlight.

GOOD TO KNOW!

• The filter system has been tested for hygiene in accordance with DIN 18879-1, Section 7.4. The materials have been selected in accordance with the requirements of DIN 18879-1 and EN 14898. The pressure resistance of the system is in accordance with DIN 18879-1.
• The filter head includes an integrated and typetested backflow barrier in accordance with DIN EN 13959.
• Filtered drinking water is in accordance with ENn 1717, liquid category 2.
• Clean and remove lime from the equipment, such as a steam generator, before connecting it to the filter system for the first time.
• The filter contains small amounts of silver to protect against microbiological growth. Because of this, small amounts of silver may enter the water. The silver contents are harmless and below the recommendations of the World Health Organization (WHO).

5.2. Qualified personnel
Only professional and qualified personnel may install, use and maintain the filter system.

• Professional personnel: has received training on their tasks and potential risks that can be caused by misuse.
• Qualified personnel: has professional training, skills and experience, as well as knowledge of the applicable legislation, to use and maintain the filter system.

5.3. Actions after downtime

• If the equipment will be unused for longer periods, close the inlet stop valve of the filter system.

5.4. Change interval
The steam generators have the following capacities:

• 2 kW: 2.6 kg/h
• 3 kW: 3.9 kg/h

In the steam shower column’s control panel menu S-06, you can see the hours of operation (more detailed instructions on the S-06 setting are found in the Steam shower column instructions). Using this information, you can calculate how many hours it takes for the filter insert capacity to be used up.
The filter insert must be replaced when it has reached the capacity specified in Table 1. It is recommended to replace the filter insert every 12 months, even if there is capacity left. After a pause of more than 4 weeks, it is recommended that you run rinsing water through the filter like in the initial installation.
5.5 Disposal
Used filter inserts, extra components and packaging materials must be disposed of according to the local regulations. If possible, please recycle all parts. This helps us protect the environment.

INSTALLING THE FILTER

6.1. Water quality
The incoming water used in the filter system must be cold and meet the statutory quality standards for potable water.
WARNING! Misuse is dangerous!
Not using the system as intended poses a health hazard, e.g. if the filter is used to process water that does not meet the quality requirements for potable water.
6.2. Pressure
PLEASE NOTE! The nominal pressure must not exceed 6 bar. If the nominal pressure ex- ceeds this value, a decompressor must be installed between the water source and the filter system.
GOOD TO KNOW! Installing a decompression valve may reduce the flow. For the filter system to work properly, inlet pressure must not drop below 1.2 bar.
Pressure spikes must be avoided. If such spikes occur, the combined pressure of the spike and the pressure required for no-load running must not exceed the nominal pressure of 6 bar. A positive pressure spike must not exceed 2 bar, and a negative pressure shock must not drop under 50% of the settle-out pressure (see DIN 1988, Section 2.2.4).
6.3. Selecting the materials
When selecting the materials, please note that ionexchange water is slightly acidic (it contains carbonic acid). To avoid corrosion, we recommend not installing components made of copper or coated with zinc, chrome or nickel between the filter system and the equipment.
6.4. Opening the filter package
Take the filter out of the package and check that it is intact and undamaged (no damage from the transport).
PLEASE NOTE! Defective or damaged parts must be replaced immediately. Ensure that the working environment is clean. Keep the packaging materials away from children due to a risk of suffocation!
Remove the plastic film and dispose of it as plastic waste according to the local regulations on waste. This will reduce the waste’s environmental impact.
6.5. Installing the wall mounting and the filter head
6.5.1 Installing the wall mounting
**PLEASE NOTE!** Read the technical data, instructions for use and safety instructions before the installation. Note the installation measurements and the bending radius when installing additional equipment (such as hoses or connector kits). Action:

1. When installing the filter system, choose a location where the filter can be connected to a water source as easily as possible.
2. The filter system can be used either vertically or horizontally (see Figure 4).
3. The distance between the figure and the floor or the wall opposite it must be at least 65 mm to leave enough room to replace the insert (see Figure 4). When the filter insert is installed horizontally, you must ensure that it is firmly against the floor.
4. During the installation, direct the wall mounting so that you can easily place the filter head and the filter insert later.
5. Mark the time of installation (month/year) in the area reserved for this on the side of the filter insert.  

6.5.2. Installing the filter head
PLEASE NOTE! The filter head must never be exposed to the water source’s pressure for a prolonged time without the filter part being connected. The fastening’s torque must not exceed 15 Nm.
GOOD TO KNOW! Installing a decompression valve may reduce the flow. For the filter system to work properly, inlet pressure must not drop below 1.2 bar.
Action:

1. Fasten the filter head to the wall mounting.
2. Connect the inlet and outlet hoses (pay attention to the bending radius!) to the filter head.
3. Connect the inlet hose of the water source to the stop valve at the inlet.
4. Connect the outlet hose of the filter system to the equipment.

6.6. Determining filter capacity and by-pass settings
The by-pass setting and the filter capacity are based on the water’s carbonate hardness and the utilisation rate of the filter insert.
Action:

1. You may request information about carbonate hardness from your water supplier. Alternatively, it can be analysed with a quick test (see Figure 5). You need to select the bypass setting based on the carbonate hardness and purpose of the equipment. The typical filter capacities are specified in Table 1.
2. There are four by-pass settings available. The default setting is “2”. The by-pass setting can be changed by turning the cap of the filter head (see Figure 6). Turn the cap to the left or right until the mark is pointing at the desired number and the cap snaps in
   place.

GOOD TO KNOW! After a pause of more than 4 weeks, it is recommended that you run rinsing water through the filter like in the initial installation. 6.7. Installing the filter insert
PLEASE NOTE! The filter insert must only be installed in an original Harvia filter head. Make sure that the working environment is clean and be careful not to get the filter system dirty.
Actions:

1. Remove the protective film from the filter insert and also remove the protective cap.
2. Before installing the filter insert, mark the installation date and future replacement date (12 months from the installation, at the latest) on the label on the insert (see Figure 7).
3. Install the filter insert in the filter head by turning the insert counter-clockwise (see Figure 8).
4. The filtering system must be flushed when setting up the system. Run water through the filter with the S-07 setting on the control panel until water flows out of the steam nozzle. (For more detailed instructions on the operation of S-07, see the Steam nozzle instructions.)

6.8. Replacing the filter insert
PLEASE NOTE! Disconnect the device from the mains before replacing the filter insert!
Do as follows:

1. Disconnect the device from the mains. Remove the steam nozzle and glass for technical space (see section Initial installation of Nova steam shower column)
2. Remove the filter insert from the filter head by turning it clockwise (see Figure 9).
3. Check if the carbonate hardness of the incoming water has changed, and, if necessary, update the insert replacement interval and the by-pass setting to fit the changed conditions.
4. Install the new filter insert by following the instructions in Section 6.7. (see Figure 9).
5. Rinse and empty the filter insert by following the instructions in Section 6.7.
6. Dispose of the used filter insert according to the local regulations on waste.

MAINTENANCE

All technical equipment requires regular maintenance to function smoothly.
PLEASE NOTE!

• Clean the surface of the filter system regularly with a damp cloth and maintain hygiene when replacing the filter insert. Do not use corrosive chemicals or cleaning agents.
• Inspect the pressure hoses: regularly in case of cracks.
• After a pause of more than 4 weeks, it is recommended that you run rinsing water through the filter like in the initial installation.
• Replace the filter head: after 5–10 years.
• Replace the pressure hose: after 5 years.
