Any electronic air cleaners or other devices may require specific air flows, consult installa- tion instructions of those devices for requirements START-UP PROCEDURE AND ADJUSTMENTExample The *MVC80704BX is set for 990 CFM on cooling, the “ADJUST” is set to “+” plus. The four heating speeds available are “A Plus”, “B Plus”, “C Plus”, and “D Plus”. “A Plus” has a rise of 38F for both stages which is within the 20-50Frise range for the *MVC80704BX . This setting will keep electrical consumption to a minimum.
