Platsky 599123 Overflow Safety Switch

Product Description

The PLATSKY 599123 is an overflow safety switch designed to detect and respond to condensate overflow conditions in HVAC systems. When the condensate drain pan reaches a high-water threshold, the switch interrupts system operation to prevent water damage to ceilings, walls, and equipment. This type of safety device is a standard component in residential and light-commercial air conditioning and air handling installations. HVAC technicians install the 599123 as a protective control in systems where drain pan overflow poses a risk to occupied spaces below the equipment.

The 599123 is suited for use in residential and light-commercial HVAC applications where condensate management is critical. Typical installations include attic-mounted air handlers, horizontal evaporator coil configurations, and packaged units with internal drain pans. The switch mounts in or near the secondary condensate pan and wires into the low-voltage control circuit to shut down the system before overflow occurs.

Key Features

• Interrupts system operation on condensate overflow to prevent water damage
• Designed for integration into low-voltage HVAC control circuits
• Compact form factor suitable for tight equipment access areas
• Lightweight construction at 0.29 pounds for easy handling during installation

Compatibility

Designed as an OEM-style replacement overflow safety switch for residential and light-commercial HVAC condensate drain pan applications.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect power to the air handler or furnace before wiring the switch into the control circuit. The switch is typically wired in series with the thermostat low-voltage circuit so that a high-water condition will break the call for cooling. Refer to local mechanical codes and the equipment manufacturer wiring diagram for correct placement and wiring configuration.
