How to Install 3 M Shower Filter

How to Replace 3 M Shower Filter Refill

The 3M Shower Filter is designed to enhance your showering experience by filtering tap water. This user manual provides comprehensive guidance on its installation, usage, maintenance, and troubleshooting.

Function Description

The 3M Shower Filter is primarily designed to filter tap water used for showering. It aims to improve water quality for personal hygiene purposes. The filter is compatible with both standard and premium shower systems. It is intended for use with tap water only and is not recommended for filtering unidentified water or water containing microorganisms. The device is designed to be installed between the shower hose and the faucet, or directly onto the faucet, depending on the specific setup.

Usage Features

Installation: The installation process involves three main steps:

Remove the shower hose from the faucet.
Connect the 3M shower filter to the bottom of the faucet.
Connect the separated hose to the bottom of the 3M shower filter.

It is crucial to handle the shower filter carefully during installation. The manual explicitly states that if the head is rotated during installation or replacement, there is a risk of damage, and the head should never be turned. The product can be tightened by hand, but if a separate tool is used, overtightening should be avoided to prevent damage. If the head is rotated excessively after installation, a safety pin might come off; however, this does not affect the product's functionality.

Precautions for Use:

The filter should only be used with tap water and is not suitable for filtering unidentified water or water containing microorganisms.
Before installation, check the water pressure. If the pressure is 4.0kg/cm² or more, consult an expert for a pressure-reducing device.
The filter is not recommended for use with valved shower heads.
After installation, run water for at least 5 seconds.
For premium shower filters, some activated carbon powder may be released during initial use. In such cases, run water for 1-2 minutes or more until it clears.
The filter is intended for showering purposes only and not for drinking water.
The main material is polycarbonate (PC), and it should be used within a temperature range of 4-45°C.
Do not lubricate the rubber O-ring or clean the product with chemicals.
Avoid direct sunlight during use or storage.
The filter is compatible with both standard and premium shower systems.
Applying external force to the filter after installation may cause damage.
Ensure there is sufficient space (at least 6cm) between the faucet and the wall for proper mounting.

Maintenance Features

Filter Replacement: The filter replacement process is also straightforward:

Pull the shower filter head lock to separate it from the body.
Twist the separated body in the direction of the arrow.
Replace the dirty filter with a new one.
Reassemble in reverse order and reinstall the shower filter.

Replacement Schedule: Filter replacement is recommended when the 3M logo on the filter is clearly visible. Based on a daily usage of 40L for adults, the typical filter replacement cycle is 2-4 months. However, this duration may vary depending on the specific water environment and usage conditions. Regular checking of the filter's color is advised to prevent flow rate decrease due to clogging. The filter should also be replaced if it becomes dirty or if the water pressure weakens.

Troubleshooting Leakage: The manual provides a self-diagnosis guide for five common leakage scenarios after installation:

CASE A: Leak between the nut joint and the faucet.
- Cause: Missing rubber stopper (gasket) or improper tightening.
- Solution: Ensure the rubber stopper is present and tighten the nut joint further until it no longer turns. A spanner can be used if necessary, but avoid turning the shower filter head/body to prevent damage.
CASE B: Leaks between the nut joint and the head.
- Cause: Defective product assembly.
- Solution: Return or exchange the product.
CASE C: Leaks between the head and body.
- Cause: Foreign substances in the small rubber O-ring mounted on the body, causing intermittent leakage.
- Solution: Separate the body and head, wash the rubber O-ring lightly with water, and reassemble.
CASE D: Leaks between the body and bottom.
- Cause: Foreign substance in the large rubber O-ring under the body, causing intermittent leakage, or improper tightening.
- Solution: Remove the bottom, lightly wash the O-ring with water, and reassemble.
CASE E: Leak between the tail and the shower hose.
- Cause: Shower hose not properly tightened.
- Solution: Refit until no more turns.

Post-Replacement Leakage: If intermittent leakage occurs after replacing the shower filter, it may be due to the rubber ring getting caught between the body and the head or bottom. In this case, separate the product and parts, soak the rubber ring in water sufficiently, and then reassemble it.
