Milton Roy a2sa-x115 Condensate Pump 115V Aux Switch

Product Description

The MILTON ROY a2sa-x115 is a condensate removal pump designed for HVAC and refrigeration applications where gravity drainage is not possible. It operates on 115 volts and features a 1-gallon reservoir with a maximum lift head of 22 feet, making it capable of pumping condensate to a distant or elevated drain point. The unit includes an auxiliary switch for high-water-level shutdown or alarm integration and is configured with an alternate inlet to accommodate varied piping arrangements. Licensed HVAC technicians and refrigeration service technicians are the typical installers for this type of equipment.

This condensate pump is suited for residential and light commercial installations where air handlers, fan coils, mini-splits, or other cooling equipment produce condensate that cannot drain by gravity. The alternate inlet configuration allows flexible connection from either side of the reservoir, simplifying rough-in where access or line routing is restricted. The auxiliary switch enables integration with equipment shutdown circuits, automatically cutting power to the system if the reservoir reaches a high-water condition, protecting equipment and property from overflow damage.

Key Features

• 115-volt operation compatible with standard residential and light commercial power circuits
• 1-gallon reservoir capacity provides buffer volume during high condensate production cycles
• 22-foot maximum lift head allows pumping to distant or elevated drain points
• Auxiliary switch supports high-water shutdown or alarm circuit integration
• Alternate inlet configuration offers flexible installation orientation

Compatibility

Designed as an OEM-style replacement or new-installation condensate pump for residential and light commercial HVAC systems, including air handlers, fan coils, and mini-split indoor units that produce condensate requiring forced removal.

Installation Notes

Installation should be performed by a licensed HVAC technician following local mechanical codes. Disconnect power to all associated equipment before connecting or servicing the pump. Ensure the discharge line is routed with continuous upward slope or properly supported to prevent sag that could restrict flow and cause premature pump cycling. Test the auxiliary switch function and verify high-water shutdown operation before returning the system to service.
