Installation Guidelines

Preparation

Before installation, ensure the foundation or chamber opening is properly leveled, clean, and free from debris or loose materials. Verify that the manhole frame and cover are of matching dimensions and material grade. Confirm that the bedding mortar or concrete mix is prepared according to site requirements.

Installation Steps

Position the manhole frame accurately over the prepared opening, ensuring correct orientation and level alignment with the surrounding surface.
Apply a suitable mortar or concrete bedding layer beneath the frame to provide uniform support and stability.
Press the frame gently into the bedding material and check that it sits evenly and flush with the pavement or road surface.
Allow the bedding material to cure completely before placing the manhole cover to ensure proper load-bearing capacity.
Install the cover securely onto the frame, ensuring it fits snugly and operates smoothly without wobble or gaps.
Inspect the completed installation for alignment, stability, and watertightness before opening for use.
