Frequently Asked Questions - BA195 MINIBA HONEYWELL

How to install the BA195 disconnector?

Install the disconnector on a horizontal pipe with the outlet connection facing downwards. Install shut-off valves before and after the device. Flush the pipe before installation. Observe the flow direction indicated by the arrow. Ensure the location is frost-protected and well ventilated.

What is the minimum required inlet pressure?

The minimum inlet pressure is 1.5 bar. The maximum pressure is 10.0 bar.

How to clean the disconnector cartridge?

Close the inlet valve, depressurize the outlet side, close the outlet valve, remove the outlet connection, remove the retaining ring then the cartridge. Clean the cartridge with clean water without using solvents or alcohol. Reassemble in reverse order by pressing until it clicks.

How often should the BA195 be inspected?

Inspection is recommended every 6 months (depending on local conditions). It must be carried out by an installation company using a test device such as TK295 or TKA295.

What to do if the drain valve opens without reason?

This may be due to pressure surges or pressure variations. Install a pressure reducer upstream. If the cartridge is dirty, clean it. If the valve does not close, check for deposits on the seat or O-ring.

How to replace the cartridge?

Close the inlet and outlet valves, depressurize, remove the outlet connection, remove the retaining ring, extract the cartridge. Do not disassemble it. Insert the new cartridge until it clicks. Reassemble and check function.

What spare parts are available?

Spare parts include: complete cartridge KE195, check valve 2110200, and outlet connection AT295.

Can the BA195 be installed vertically?

No, installation must be horizontal with the outlet connection downwards. Vertical installation is not in accordance with the instructions.

How to test the check valve function?

Use a test device such as TK295 or TKA295 following the service instructions provided with the device. A quick check can be performed by reducing the inlet pressure.

What to do in case of low flow rate?

The inlet strainer is probably clogged. Remove the strainer and clean it. If the problem persists, also check the cartridge.

USER MANUAL BA195 MINIBA HONEYWELL

Technical line drawing of a pipe fitting with multiple ports and fittings (no text or symbols)

Keep instructions for later use!

1. Follow the installation instructions.
2. Use the appliance

• according to its intended use
- in good condition
• with due regard to safety and risk of danger.
3. Note that the appliance is exclusively for use in the applications detailed in these installation instructions. Any other use will not be considered to comply with requirements and would invalidate the warranty.
4. Please take note that any assembly, commissioning, servicing and adjustment work may only be carried out by authorized persons.
5. Immediately rectify any malfunctions which may influence safety.

2. Functional description

BA type backflow preventers are divided into three pressure zones. The pressure in zone ① is higher than in zone ②, which in turn is higher than in zone ③. A discharge valve is connected to zone ② which opens at the latest when the differential pressure between zones ① and ② falls to 0.14 bar. The water from zone ② discharges to atmosphere. In this way the danger of back pressure or back syphonage into the supply network is prevented. The pipework connection is interrupted and the drinking water network is protected.

7. Assembly

7.1 Installations Guidelines

• Install shutoff valves before and after backflow preventer
- Install in horizontal pipework with the discharge valve downwards
- Ensure good access o Simplifies maintenance and inspection
- Backflow preventers of this type have an integral strainer which protects the device from the ingress of dirt. With highly polluted water a fine filter should be installed upstream to ensure the correct function of the device.
- Do not install in places where flooding can occur
- The installation environment should be protected against frost and ventilated well
- Install discharge pipework which has adequate capacity

7.2 Assembly instructions

1. Thoroughly flush pipework
2. Install backflow preventer
3. Install in horizontal pipework with discharge connection directed downwards
4. Note flow direction (indicated by arrow) o Install without tension or bending stresses
5. Provide a straight section of pipework of at least five times the nominal valve size after the backflow preventer
6. Attach drain pipe to discharge connection (plastic pipe HT 50)
7. The appliance is ready for use
