Description
Product Overview
The SS1 condensate overflow float switch is engineered specifically for HVAC applications where reliable condensate management is critical. Constructed from Schedule 40 transparent blue PVC, the housing offers both durability and visual inspection capability, allowing technicians to quickly verify water levels without disassembly. Inside the housing, a water‑sealed magnetic reed switch provides a non‑contact detection method that resists corrosion, sticking, and false triggering even in harsh environments. The unit includes a 3/4 inch threaded adaptor, a bushing, and a cap that can be detached for cleaning, as well as a 6 ft insulated wire pre‑terminated with a thermostat connector for straightforward wiring. Dimensions of 4.3 × 2.3 × 1.1 inches and a weight of 3.21 oz make the switch compact enough to fit into tight spaces while still delivering robust performance.

Usage
This float switch is versatile enough to be installed in a variety of HVAC configurations, including residential air‑conditioner condensate drains, commercial rooftop units, and auxiliary drainage lines. It can be mounted horizontally, vertically, or on a sloped pipe, thanks to the included adaptor and flexible mounting options. The switch is ideal for primary drain lines where overflow could cause water damage to flooring, walls, or equipment, as well as for secondary or auxiliary outlets that provide redundancy in larger systems. The 6 ft wire length gives ample reach to connect the switch to a thermostat or control board, enabling automatic shut‑off of the HVAC unit when the water level rises above the calibrated threshold. This proactive protection helps prevent costly repairs and extends the lifespan of the entire HVAC system.

FAQ
How does the float switch detect overflow?
The switch uses a magnetic reed sensor that is activated when the float rises with the water level. When the float reaches the preset position, the magnet closes the reed circuit, sending a signal to shut off the HVAC unit.
Can the switch be installed on a sloped drain line?
Yes. The included 3/4 inch adaptor and flexible mounting options allow the switch to be positioned on horizontal, vertical, or sloped pipes, making it adaptable to most HVAC drainage configurations.
Is the PVC housing UV‑stable for outdoor use?
The Schedule 40 PVC used in this switch is formulated to resist UV exposure and chemical degradation, making it suitable for both indoor and outdoor installations where sunlight may be present.
What maintenance is required?
Periodically inspect the transparent housing for debris buildup. The detachable cap and tapered cams enable quick removal of the float assembly for cleaning, ensuring continued accuracy and reliability.
What warranty does GZKEFEIS provide?
GZKEFEIS offers a standard one‑year warranty covering manufacturing defects, along with access to technical support for installation assistance and troubleshooting.
