SETTING THE CONTROL

CONTROLS WITH ADJUSTABLE DIFFERENTIAL

The movable indicator points to the temperature at which the contacts open. The fixed indicator points to the temperature at which the contacts close. The difference between these two indicators is the differential.

To set the control:

1.Use a screwdriver in the adjusting slot (A) on the front of the control to turn the dial so that the fixed indicator (B) points to the temperature at which the contacts will close.

2.Turn the differential adjusting screw (C) until the movable indicator (D) points to the temperature at which the contacts will open.

CONTROLS WITH A FIXED DIFFERENTIAL

The indicator (B) points to the temperature at which the contacts open.

To set the control:

Use a screwdriver in the adjusting slot (A) on the front of the control to rotate dial until the desired temperature at which the contacts will open is positioned directly under the indicator (B).

CONTROLS WITH ADJUSTABLE STOPS

CAUTION

Setting stop higher than control being replaced could cause personal injury and/or property damage.

1.Loosen stop screw (E) with enclosed wrench.

2.Set dial to original equipment manufacturer's specification.

3.Without moving the dial, move stop tab (F) against indica- tor.

4.Retighten stop screw (E).
