Any insulation on the ground wire should be stripped back about ¾ inch. The ground lead must be connected to the pillar terminal marked “GR.”

Make sure the terminal block screws are tightened securely. Loose connections can cause wires to heat up.

Make sure that the ground wire is wrapped around its terminal stud and into the saddle washer. The nut should be tightened securely.

Attach the front cover and tighten the retaining screws.

Checking for leaks

Let the water run through the unit for a few seconds. Check that no pipe joints leak.

Adjusting the temperature dial

The temperature adjustment is made using the dial on the bottom edge of the unit. The adjustment is between approximately 95°F and 135°F. Turning the dial clockwise increases the temperature setting as indicated by the marking on the unit.

Adjusting the flow

Open fully both inlet and outlet shut-off valves at the heater, then :

Turn on fully the highest flowing hot water faucet (e.g., bathtub) closest to the outlet connection.

Adjust the outlet shut-off valve until the water flow rate from the hot faucet corresponds to the value given in Graph 1 on Page 8.
