Notes:
1. During unit operating in area 1, the water
f low range should be 70%-130% of unit rated
water f low;
2. When EWT of evaporator lower than
10℃(area 2), unit may display anti-freezing
protection note (def ault 5℃). If need to
operate in this area, the water f low of the
evaporator shall meet the f ollowing
