Drain System
Drain Pump: 120 Volts AC, 27 ohms, .65 amp
A drain complete drain cycle is approximately 2 minutes long. To ensure
proper operation, the drain pump will cycle on and off several times.
• The Drain Pump will pump to a maximum height of 72 inches (6’)
This is Normal Operation!
• Prevents air locks in drain system
• Allows soil settlement for optimum performance
Drain pump TCO
First units out will have a resettable TCO, next version will be one shot.
Third version will be to remove the TCO for a new design cover, possibly a
new drain pump. If the TCO is open (189 degrees on harness, the pump has
an internal thermal overload of 370 degrees), the pump and wire harness
should be replaced (the TCO is part of the harness).
