To calculate the connected total indoor unit nominal capacity, simply sum up the nominal capacities of all indoor
units.
• For high static duct and vertical-horizontal air handling indoor units, a 1.3 multiplier must first be applied before
adding to the sum of other indoor units (when connected to an outdoor unit other than the LMU600HV).
• When high static duct and / or vertical-horizontal air handling indoor units are the only connected indoor units,
the multiplier is 1.2.
CAUTION
Capacity is based on standard length and maximum allowance length is on the
basis of reliability.
