AUTO BLEED ACTIVATION AND OPERATION

There is a possibility that under certain conditions, the Therma-Flo EHT front discharge pump may experience issues with air locking. In order to allow the user to easily eliminate the air lock, these pumps are equipped with an Auto Bleed Valve to release air.

Follow these steps to activate the Auto Bleed Valve:

1.Drain the pump.

2.Remove the threaded cap with seal and the ball supplied on the pump.

3.Drill a small (approximately 2 mm) hole inside the cavity through the pilot hole in the pump housing.

4.Replace the ball and cap with seal.

5.Connect one end of a small tube to the valve cap and the other end to an appropriate drain.

6.Refill the pump.

Once completed, trapped air should be automatically released during filling.
