Drinking water filter with regulator
RTF 692 - RTF 694
RTF 692 - RTF 694
The drinking water filter with regulator is a combination of a pressure regulator and a drinking water filter. This product combines the best features of these two products: reliable pressure reduction and easy filter cleaning. As a drain hose can be connected to the green bottom connector, the filter can be cleaned without unnecessary pouring of water.

The drinking water filter with regulator is primarily designed for filtering drinking water while allowing pressure limitation in water supply and other installations where aggressive and explosive media are not present. It is typically used to protect devices or systems from particles in the water supply network and excessive pressure. The pressure behind the pressure reducer can be adjusted within a certain range and is independent of the inlet pressure.
The outlet pressure is adjustable and does not change with variations in inlet pressure. The desired pressure can be easily set before installation using the green knob on top of the valve. The factory setting is 3 bar for convenience but can be adjusted to meet specific requirements within a range of 1.5 to 6 bar.
The pressure regulator must be installed in a horizontal position with the filter facing downward. Pay attention to the flow direction, which is marked with an arrow on the housing. For proper operation, a straight pipe section of at least 5x DN must be present before and after the regulator.
The drinking water filter with regulator is equipped with an integrated filter designed to protect the household water system from contaminants such as dirt, rust, and sand particles. This filtration ensures clean and safe water flow, reduces the risk of device damage, and maintains system efficiency over time.
The built-in pressure gauge allows for easy monitoring of the system pressure, ensuring reliability and precise control. Be careful not to exceed the specified values on the pressure regulator scale, as this could damage the valve. After each new adjustment of the outlet pressure, the regulated water supply should be opened and closed. We recommend maintenance by authorized installers in accordance with DIN 1988 standards. Check the filter condition several times a year and clean or replace it as needed. The necessary maintenance tools are included with the pressure reducer.

Operating Data
Measurement scale: 0–10 bar
Mesh size: 0.3 mm
Medium: Water
Maximum inlet pressure: 16 bar
Output pressure range: 1.5–6 bar
Factory setting: 3 bar
Medium temperature range: 0.5–40 °C
Pressure gauge connections: 1/4" F (ISO 228-1)
Connections: External thread according to ISO 7-1 and ISO 228
Medium
The water quality must comply with the ÖNORM H 5195 and VDI 2035 standards. The use of ethylene or propylene glycol in a mixing ratio of 25–50% is permitted. EPDM seals are sensitive to lubricants containing mineral oils, which can cause seal damage. When using ethylene glycol-based products for frost and corrosion protection, follow the manufacturer’s documentation.
Pressure Gauge
The membrane pressure regulator is equipped with a pressure gauge with a 0–10 bar scale, allowing precise pressure monitoring in the heating system. The pressure gauge can be installed on either side of the valve housing, as two 1/4" connection points are available, providing flexible installation options.
Pressure Adjustment
To adjust the pressure on the membrane pressure regulator, use the green adjustment knob located at the top of the product. The knob allows easy manual pressure adjustment in the water circuit. Turn the knob clockwise to increase the pressure and counterclockwise to decrease it. The knob is designed for comfortable manual operation, enabling quick and simple adjustment without additional tools.
Union Nut with Free-Rotating Coupling
The membrane pressure regulator is designed for connection to the system using a union nut with a free-rotating coupling (included in the set). This allows easy maintenance and the possibility of disconnecting the valve during servicing.
Filter with Drain
The drinking water filter with a pressure regulator contains a filter that removes particles larger than 80-100 µm. The filter should be flushed every 6 months or as needed. To flush the filter, simply unscrew the green drain valve 2-3 times in succession. Be careful that the green drain valve is unscrewed by a maximum of 0.5 to 1 turn, as otherwise, excessive water discharge may occur. The drain valve also has an external G3/4” thread, which allows for the attachment of a hose adapter to discharge impurities via a hose. During the cleaning phase, a continuous supply of drinking water to the user is ensured. If the filter is in poor condition, it can be replaced with a new one (2 6301 00). The necessary maintenance tool is included in the package. We recommend maintenance by an authorized installer in accordance with DIN 1988 standards.

INSTALLATION:
Before installation, thoroughly rinse the system. Install the regulator in a horizontal position with the filter facing downward. Pay attention to the direction of flow, which is marked on the housing. For proper operation, there must be a straight pipe section of at least 5x the pipe DN before and after the regulator. The included pressure gauge is screwed into the pressure regulator (it can be mounted on either side of the regulator). A shut-off valve must be installed both before and after the pressure regulator.
