Selection of installation place
• EThe cooling performance may decline considerably when total operating capacity of cooling indoor units is
less than 4 HP while ambient temperature is below 0°C.
• EWhen system capacity is greater than 28 HP, height difference between indoor units is limited to 3 m. If the
piping exceeds 3 m with a capacity greater than 28 HP there may be a case of capacity shortage in cooling.
Height between outdoor units
Ensure that the header unit is installed below all connected follower outdoor unit(s).
