Liberty LCU-MS2 Mini-Split Condensate Pump with Line Cover Kit — Quiet, Compact, Dual-Voltage

Liberty Pumps LCU-MS2 Condensate Pump With Line Cover Kit for Mini-Splits

The Liberty LCU-MS2 is engineered for compact, reliable condensate handling from wall-mounted, ductless mini-split systems up to 23,500 BTU (7 kW), fan coils, and suspended ceiling A/C systems. Built with quiet operation, solid-state switch technology, and a clear reservoir for visual inspection, it’s ideal for tight mechanical closets or behind equipment. 

Key Features & Benefits

• Quiet operation — minimal noise in indoor settings.
• Solid-state switch technology — more reliable and precise switching than mechanical floats. 
• Clear reservoir — lets you visually inspect water level, float, and filter. 
• Compact 2-piece design — reservoir can be placed inside the air handler while the pump controller can be external.
• 5/16" (7.9 mm) pump discharge port — standard small condensate tubing. 
• Normally-closed relay (3A resistive, 250V) — supports high-water alarm integration.
• Voltage range: 100–240V, 0.19A, 30W — works across both 115V and 230V systems. 
• Thermal protection (176°F / 80 °C) — helps prevent damage from overheating. 

Specifications

• Includes decorative line-set cover kit with 90° elbow, ceiling plate, cable ties, and right/left side installation flexibility.
• Reservoir mounts within the elbow, giving a clean visual run along the line set. 

Installation Notes

• The two-piece configuration lets you position the reservoir inside the air handler and the pump controller outside
• The pump must be within 6.5" (2 m) of the reservoir. 
• Reservoir must be flat and horizontal. 
• The pump can operate in any orientation but the reservoir has to be level. 

The LCU-MS2 is a compact, versatile solution for drain and condensate handling in mini-split and similar HVAC systems — offering solid-state reliability, visual diagnostics, and broad voltage compatibility.
