1. DIFFERENT POINTS OF THE MAIN PARTS

This model is added with the passive filter to the fan driving circuit of the existing model and then Type name is changed. (“-E” is added to the end of the Type name.)

1. Newly changed contents

Addition of passive filter against the harmonic

2. Contents change of running

1) Reduction in refrigerant amount

Applied models: MMY -MAP0801H T8 (-E), MAP1001H T8 (-E), MAP1201H T8 (-E) (O nly for S MMS heat pump models) U nit: k g

2) Change of oil tank appearance

Applied models: S MMS series, S H RM series

Changed positions

As shown in the left, the oil tank appearance of A03-009, A04-008 are changed.

As there is especially no problem in expression of the refrigerating cycle diagram, the diagram is not changed.
