Overflow Switch evacuates condensate from AC systems.
September 2, 2010 -
Featuring integral pump, EZ Trap® UltraSwitch Model EZT-356 helps prevent property damage from condensate drain pan overflows on residential and commercial air conditioners. When connected to air conditioner's overflow outlet with 1 in. dia PVC fitting, self-evacuating unit uses stainless steel electronic probes to sense rise in condensate levels caused by blocked outlet. Blocked drain pans are evacuated at rate of 2 gal/30 sec by 24 V Aspen pump.

EZ Trap® Introduces HVAC's Only Self-Evacuating Condensate Overflow Switch
The EZT-356 is the world's most failsafe method of preventing overflow incidents from commercial air conditioner drain pans.
Airtec Products Corp., Fall River, Mass., now offers EZ Trap® UltraSwitch Model EZT-356, the HVAC/R industry's only self-evacuating overflow cut-off switch with an integral mini pump to help prevent property damage from condensate drain pan overflows on residential and commercial air conditioners.
When connected to an air conditioner's overflow outlet with a connecting one-inch-diameter PVC fitting, the EZT-356 senses a rise in potential property-damaging condensate levels caused by a blocked outlet. Blocked drain pans are evacuated at a rate of two gallons/30-seconds by the heavy-duty 24-v integral Aspen pump, which was designed exclusively for the patented EZT-356.
Most mechanical overflow switches use a float switch mechanism and only momentarily deactivate the air conditioner in situations of partially blocked drains. Conversely, the EZT-356 uses stainless steel electronic probes to sense rising condensate levels. The EZT-356 deactivates the air conditioner while the integral mini pump evacuates the excess condensate into its own 3/16-inch vinyl tubing drain line. The pump remains live as a second line of defense for instances such as a deactivated air conditioner's iced coil, which can potentially thaw and overflow a blocked drain pan. To reactivate the air conditioner, a reset button on the EZT-356 must be manually pressed-usually by a service tech who would typically investigate and clear the blockage. The status of the system is clearly indicated at all times by a green/red LED located on the EZT-356's pump.
Other overflow switch brands can reactivate the air conditioner once the condensate level recedes without signaling a partial blockage, which will simply repeat the cycle and potentially lead to mold, mildew and other IAQ problems.
o For rare cases of an air conditioner with no overflow outlet, the EZT-356 can be combined with most EZ Trap condensate models via a one-inch-diameter cross fitting in the condensate drain line.
o The EZT-356 can switch any voltage from 24-v to 230-v at 5-amps.
o Capacity is 3.7-g/hr at 0 head to 0.8-g/hr at 26-foot head.
o An integral 15-second delay prevents false alarms.
o Quiet operation of 21-db.
o Stable operation in environments ranging from 20°F to 160°F.
