Setup and Installation
This section outlines the steps for assembling and installing your utility sink.
Unpacking and Inspection
Carefully remove all components from the packaging. Inspect all parts for any damage that may have occurred during shipping. Report any damage to the carrier immediately.
Components
- Sink Bowl Assembly (with back splash)
- Legs (typically 4)
- Adjustable Bullet Feet
- Basket Drain
Assembly Steps
- Attach Legs: Securely attach the four legs to the designated mounting points on the underside of the sink bowl assembly. Ensure all fasteners are tightened appropriately.
- Install Adjustable Feet: Thread the adjustable bullet feet into the bottom of each leg. These feet allow for leveling the sink on uneven surfaces.
- Install Basket Drain: Insert the included basket drain into the drain opening of the sink bowl. Follow the manufacturer's instructions for the drain assembly to ensure a watertight seal.
Placement and Leveling
Position the assembled sink in its desired location. Use a spirit level to ensure the sink is perfectly level by adjusting the bullet feet. Proper leveling is crucial for efficient drainage.
Plumbing Connections
Connect the sink's drain outlet to the building's wastewater system according to local plumbing codes. If a faucet is to be installed (sink comes without faucet), connect water supply lines to the faucet mounting centers (8 inches) and then to the building's hot and cold water supply.
