Frequently Asked Questions - BA298I-F HONEYWELL

What is the main function of the BA298I-F network separator?

The BA298I-F protects the drinking water network from backflow and back-siphonage by interrupting the piping via three pressure zones and a drain valve.

What maximum pressure and temperature does the device support?

Max. upstream pressure 10.0 bar, service pressure 1.5 bar, max. service temperature 65 °C.

In what position should the separator be mounted?

Horizontal mounting with outlet connection downward, in an accessible, ventilated and frost-free location.

What are the inspection and maintenance intervals?

Inspection every 6 months with the TKA295 or TK295 kit; full maintenance every 1 to 3 years by a professional.

How to clean the synthetic parts of the BA298I-F?

Use non-solvent and alcohol-free products to avoid damage. Entrust cleaning to an installer.

What to do if the drain valve opens for no reason?

This may be due to pressure surges or pressure variations. Install a pressure reducer upstream or clean the valves/valve.

How to check the operation of the check valves?

Use the TKA295 or TK295 test device according to the procedure described in the manual.

What are the essential spare parts for the BA298I-F?

Drain valve (0901856), check valves (0901652 inlet side, 0901653 outlet side), ball valve (0901662), gaskets and clips.

Can the check valves be replaced by oneself?

No, replacement must be carried out by a professional, with a specific tool (WBA-298). The valves are under spring pressure and cannot be repaired.

What accessories are recommended for maintenance?

The FY69P strainer, TKA295/TK295 test kits, and the WBA-298 valve replacement tool (depending on diameter).

11. Ersatzteile

BA298-F

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
- 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
- Where backflow preventers are installed care must be taken that discharges are safely carried away by the discharge pipework.
- Inlet pressure fluctuation, even without water draw off, can lead to brief operation of the discharge valve. It is therefore recommended that a pressure reducing valve be fitted upstream of the backflow preventer.
- No other unprotected potable water system may be connected downstream of the back flow preventer.
- Individual connections in the downstream system are not protected against backflow or back syphonage. If required, further protective measures can be installed as necessary to protect individual parts of the system
- The backflow preventer must be installed so that the discharge valve is above the surrounding maximum water table..

Use and type of installation according to DIN EN 1717

7.2 Assembly instructions

1. Thoroughly flush pipework
2. Ensure that connections on back flow preventer are clean

3. Install backflow preventer

4. Install in horizontal pipework with discharge connection directed downwards

5. Note flow direction (indicated by arrow) o Install without tension or bending stresses
6. Provide a straight section of pipework of at least five times the nominal valve size after the backflow preventer
7. Observe required clearances
8. Connect discharge pipework close coupled and without tight bends according to connection dimensions (see table)
9. Install discharge pipework in such a way that the discharge connection and the discharge valve can be removed for inspection

8. Maintenance

We recommend a planned maintenance contract with an installation company

Maintenance of backflow preventer must be carried out by authorized personnel!

8.1 Inspection

• Frequency: every 6 month (depending on local operating conditions)
• To be carried out by an installation company
- Inspection with a test control unit and maintenance-set (see accessories)

The inspection should also include ancillary equipment such as strainers and shutoff valves.

8.1.1 Testing inlet check valve

Take note of the instructions of the test control unit TKA295 or TK295

1. Procedure according to instruction of the test control unit TKA295 resp. TK295

8.1.2 Testing discharge valve

Take note of the instructions of the test control unit TKA295 or TK295

1. Procedure according to instruction of the test control unit TKA295 resp. TK295

Quick test for the discharge valve:

- Lower the inlet pressure o if the discharge valve opens (it drops), the function is o.k.

8.1.3 Testing outlet check valve

Take note of the instructions of the test control unit TKA295 or TK295

1. Procedure according to instruction of the test control unit TKA295 resp. TK295

8.2 Maintenance

We recommend a planned maintenance contract with an installation company

In accordance with DIN EN 1717 a regular maintenance must be taken.

Frequency: every 1-3 years (depending on local operating conditions)

To be carried out by an installation company

Under no circumstances may check valves and discharge valves be disassembled. To doso is highly dangerous!

8.2.1 Discharge valve

1. Close shutoff valve on inlet
2. Release pressure on outlet side (e.g. through water tap)
3. Close shut off valve on outlet
4. Unscrew pressure control line

5. Loosen screws, pull the discharge connection downwards and unscrew the discharge valve with the aid of an oil filter strap wrench.

6. Remove the discharge valve o Clean or replace as required

7. Lubricate the 'O' ring well with grease, replace damaged 'O' rings

8. Reassemble in reverse order

9. Test function (see chapter inspection)

8.2.2 Check valve

1. Close shutoff valve on inlet
2. Release pressure on outlet side (e.g. through water tap)
3. Close shut off valve on outlet
4. Open the fixing clip
5. Remove cover

Risk of injury - Check valves are under spring tension!

1. Remove the check valves o first unscrew the outlet and then the inlet check valve. An assembly tool is available as an accessory.

2. Fill with water and check for leakage o Leaking check valves must be replaced. They cannot be repaired

3. Reassemble in reverse order

• Well lubricate check valve 'O' ring with grease
- Do not damage 'O' ring during assembly
• The check valve tightening torque is 100 to 120 Nm

1. Test function (see chapter inspection)
