Installation Steps:
- Prepare the Installation Area: Ensure the floor opening is appropriately sized for the drain body (refer to Figure 3.1 for dimensions). The area must be clean and level.
- Connect to Drainage System: Connect the vertical outlet (DN50) of the drain body to the existing or new drainage pipe. Ensure a secure and watertight connection.
- Position the Drain Body: Place the drain body into the prepared opening. Adjust its height to be flush with the finished floor level, accounting for the thickness of the waterproofing layer and tiling.
- Apply Waterproofing: Apply a suitable waterproofing membrane around the drain body flange, ensuring it integrates seamlessly with the floor's waterproofing system to prevent leaks. The flange is designed to facilitate this connection.
- Install the Frame: Once the waterproofing is complete and cured, place the drain frame into position.
- Install the Odor Trap: Insert the odor trap component into the drain body. Ensure it is seated correctly to form a proper water seal.
- Place the Grille: Finally, place the stainless steel grille into the frame. It should sit flush and securely.
- Test for Leaks: After installation, perform a water test to check for any leaks and ensure proper drainage.
Note: Always consult local building codes and plumbing regulations for specific requirements regarding floor drain installation.
4. Operation
The Alcaplast APV4444 floor drain operates passively, allowing water to flow through its grille and into the drainage system. The integrated odor trap maintains a water seal to prevent sewer gases from entering the room.
Ensure that the odor trap always contains water. If the drain is not used for extended periods, the water in the trap may evaporate, potentially allowing odors to escape. Periodically pour a small amount of water into the drain to replenish the water seal.
5. Maintenance
Regular maintenance ensures the optimal performance and longevity of your Alcaplast APV4444 floor drain. The removable components facilitate easy cleaning.
Cleaning Instructions:
- Remove the Grille: Carefully lift the stainless steel grille from the drain frame.
- Remove the Odor Trap: Gently pull out the odor trap component.
- Clean Components: Wash the grille and odor trap with warm soapy water. Remove any hair, debris, or soap scum that may have accumulated. A soft brush can be used for stubborn residue.
- Clean Drain Body: Inspect the inside of the drain body for any blockages. If necessary, use a drain snake or a suitable cleaning solution to clear any obstructions.
- Rinse and Reassemble: Rinse all components thoroughly with clean water. Reinsert the odor trap, ensuring it is properly seated, then place the grille back into the frame.
Frequency: It is recommended to clean the drain every 1-3 months, or more frequently in high-use areas, to prevent clogs and maintain hygiene.
