Schedule 4—High efficiency fan installations—regression coefficients and regression constants

  For equations 7 and 18 (section 31 of this determination and section 6 of Schedule 1), if the model of the ith fan:
 (a) is of an eligible fan type indicated in the table below; and
 (b) has a motor input power within a range indicated in the table;
  the regression coefficient (ai) and the regression constant (bi) are the corresponding values indicated in the table:
