SETTING AND CHECKOUT

Setting

To set the control point of each control, insert a screwdriver in
the slotted head visible through the cover, and turn the dial of
each control to the desired setting (Fig. 7).

Because systems differ, the correct setting for one system
may not apply to another. In all cases, the equipment manu-
facturer recommendations for setting should be followed.

properly by putting it into operation and observing at least one
complete cycle. Further adjustment can then be made to
