Allied Air 76n63 Condensate Overflow Safety Switch

Product Description

The ALLIED AIR 76n63 is an auxiliary condensate overflow safety switch designed to protect HVAC systems from water damage caused by a blocked or overflowing condensate drain. When the condensate pan reaches a set level, the switch interrupts the low-voltage control circuit, shutting down the cooling system before overflow occurs. This type of device is a standard component in residential and light commercial split system air conditioning and heat pump installations. HVAC technicians install it as a primary safeguard where local codes or equipment requirements call for secondary drain protection.

This switch is suited for installations where the air handler or evaporator coil is positioned in a location where condensate overflow could cause ceiling, wall, or structural damage. Common applications include attic-mounted air handlers, horizontal installations, and any unit without a gravity-fed secondary drain line routed to a visible location. The 76n63 is referenced under the LG ACS-2 designation and cross-references to supplier code 599123, making it useful for replacement and service calls on compatible equipment.

Key Features

• Interrupts the low-voltage control circuit on condensate overflow to prevent water damage
• Referenced as LG ACS-2 and supplier code 599123 for cross-reference identification
• New condition, active production status for current service and replacement use
• Sold individually as a single unit for straightforward replacement installs

Compatibility

This switch is listed under the LG ACS-2 designation with cross-reference number 599123. For confirmed system-level compatibility beyond this reference, consult the equipment manufacturer documentation or the unit service manual.

Installation Notes

Auxiliary condensate safety switches are installed by licensed HVAC technicians. Before servicing, shut off power to the air handler at the disconnect and set the thermostat to the off position. The switch is typically wired in series with the low-voltage control circuit, commonly the 24-volt Y or G wire, per the wiring diagram included with the equipment. Follow all applicable local mechanical and electrical codes during installation.
