Installation & Handling Guidelines
⚠️ IMPORTANT: UNDERMOUNT SINK INSTALLATION PROTOCOL
-
Countertop Substrate Compatibility: Designed specifically for solid surface materials such as quartz, granite, marble, or quartzite. Not intended for laminate countertops unless specialized undermount support rings are used.
-
Cutout Template Usage: Always use the physical sink or the official MSI 1618 cutout template to trace and fabricate stone countertop openings prior to installation.
-
Watertight Seal & Mounting: Fasten the sink flange securely to the underside of the countertop using approved undermount clips and brackets. Apply a continuous bead of 100% neutral-cure silicone sealant along the rim to guarantee a watertight seal.
-
Plumbing Standard: The centered 3.5" drain opening accommodates all standard kitchen basket strainers, pop-up assemblies, and continuous-feed garbage disposals.
Care & Maintenance
-
Routine Cleaning: Wash regularly with warm water, mild liquid dish soap, and a soft cloth or non-abrasive sponge. Always wipe parallel to the brushed satin grain lines.
-
Avoid Harsh Chemicals: Do not use steel wool, wire brushes, chlorine bleach, or harsh acidic solvents, which can scratch the finish or compromise the steel’s protective oxide layer.
-
Preventing Hard Water Marks: Towel dry the basin after heavy use to prevent calcium mineral buildup and spot marks.
