Frequently Asked Questions - AUT3268 PHILIPS

How to install the Philips AUT3268 reverse osmosis system?

Installation requires shutting off the cold water supply, installing the 3-way valve, drilling a hole for the faucet (if necessary), mounting the manifold on the wall, connecting the hoses (inlet, outlet, drain, tank), and flushing the system. Follow the steps in the manual carefully, especially Chapter IV. Ensure the inlet pressure is between 0.3 and 0.7 MPa.

How often should filters be replaced?

The PP, CB, and remineralizing filters should be replaced every 6 to 12 months. The RO membrane filter lasts 24 to 36 months. Actual lifespan depends on water quality and usage. Replace earlier if flow rate or water quality drops.

What to do in case of a water leak?

Immediately close the ball valve of the 3-way valve. Check that the filters are properly inserted and the hoses correctly connected. If the leak persists, contact Philips customer service for inspection. Do not attempt to repair yourself.

What water pressure is needed for proper operation?

Inlet pressure must be between 0.3 and 0.7 MPa (3 to 7 bar). If below 0.3 MPa, install a booster pump. If above 0.7 MPa, install a pressure reducer. These accessories are sold separately.

Can I use well water or untreated source water?

No, this system is designed only for tap water compliant with European Directive 98/83. Do not use microbiologically unsafe water or water of unknown quality without prior disinfection upstream or downstream.

How to flush the system before first use?

Close the tank valve, open the faucet, and let water run for 30 minutes. Then, close the faucet, open the tank valve, and let the tank fill (1 to 2 hours). Empty the tank by opening the faucet. Repeat filling and emptying twice. The system is then ready.

Why is no water coming from the faucet?

Check that the cold water shut-off valve and the 3-way valve are open. Make sure the hoses are not kinked or blocked. If the tank is empty, wait for it to fill (1 to 2 hours). If the problem persists, consult Chapter VIII of the manual.

How to maintain the system?

Clean the housing with a damp cloth (no solvents). If unused for more than 2 days, let water run for 5 minutes. For prolonged absence, remove the filters, close the valves, and empty the tank. Before reuse, flush as for initial startup.

Does the system need electricity?

No, the system operates without electricity. It uses tap water pressure to filter. However, if pressure is too low, an electric booster pump may be needed (sold separately).

What to do if the filtered water flow rate drops?

Check that the 3-way valve is fully open. Inspect the hoses for kinks or blockages. If inlet pressure is low, install a booster pump. If a filter is clogged, replace it. Contact customer service if the problem persists.

V. Using the system

1. Before the first-time use

a. Turn off the water tank ball valve and turn on the faucet.
b. Check if there is leakage on all the connections.
c. Follow the instructions to flush thoroughly.

Flush the filters:

- Turn off the water tank ball valve. Turn on the faucet to let water flow through the system for 30 mins.

Flush the water tank

- Turn off the faucet. Turn on the water tank ball valve and let it be filled with water. This will take 1-2 hours depending on the inlet water pressure. Once the water tank is full, the system will stop filtering water.

- Turn on the faucet and empty the water tank to flush the water. Once it's empty, turn off the faucet, and the water tank will be filled again.

- Repeat the steps above 2 times.

Now the system is ready to use.

Note:

The flow rate will be less than your kitchen faucet. Water will run to the drain while the RO filter system is filtering water – even when not in use. This is normal.

Water going to drain will stop automatically when the water tank is at capacity.

VI. Maintenance

1. Routine maintenance

• Organic solvent such as gasoline etc. shall not be used for wiping the housing of the device. If cleaning is required, please gently wipe the surface of the product with a wet cloth.
• If the system is not used for more than 2 days, turn on the faucet for more than 5 minutes to flush the system.
• If the system will not be used for an extended period, take out the filter cartridges, seal them with plastic wraps, and store them in the refrigerator (not in the freezer). Turn off the three-way ball valve, turn on the faucet to empty the water tank, and turn off the water tank ball valve. Before using it again, repeat step c and step e in chapter V.

2. Filter lifetime

Note

For the best performance, please change your filter cartridge according to the filter replacement cycle suggested below. When a significantly lower flow rate is observed, we recommend changing the filters as well.

This system can only work with Philips filters.

Filter Filter lifetime
PP Filter	6-12 months*
CB Filter	6-12 months*
RO filter	24-36 months*
Mineralizer Filter	6-12 months*

* The actual lifetime of the filter cartridge depends on the local tap water quality and daily usage. The recommended replacement cycle is an average based on different local tap water quality. If the local tap water quality is below the average, the actual lifetime of the cartridge would differ from the recommended replacement cycle. If the filter cartridge is blocked, please replace it.

3. Filter cartridge replacement

a. Turn off the three-way ball valve and the water tank ball valve.
