COMBINATION TABLES
1. Capacity as rated: 0 ft. above sea level with 25 ft. of refrigerant piping.
0 ft. level difference between outdoor and indoor units.
2. Cooling capacity rating obtained with air entering the indoor unit at 80°F dry bulb (DB) and 67°F wet bulb
(WB), and outdoor ambient conditions of 95°F dry bulb (DB) and 75°F wet bulb (WB).
3. Wiring cable size must comply with the applicable local and national codes.
4. The specification may be subject to change without prior notice for purpose of improvement.
5. At least two indoor units must be connected.
6.
Combination tables with calculated SEER and HSPF are outside the scope of AHRI 1230 test standard.
*
The indoor unit must be a non-ducted type.
Note:
FOR PROPER SYSTEM OPERATION:
1. At least two operable indoor units must be connected to the outdoor unit.
2. Total connected indoor unit nominal capacity must be a minimum 40% and a maximum of 133% of outdoor unit nominal capacity.
3. To calculate the connected total indoor unit nominal capacity, simply sum up the nominal capacities of all indoor units.
· For 24,000 and 36,000 Btu/h 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 smaller indoor units.
· When high static duct and/or vertical-horizontal air handling indoor units are the only connected indoor units, the multiplier is 1.2.

COMBINATION TABLES
1. Capacity as rated: 0 ft. above sea level with 25 ft. of refrigerant piping.
0 ft. level difference between outdoor and indoor units.
2. Cooling capacity rating obtained with air entering the indoor unit at 80°F dry bulb (DB) and 67°F wet bulb
(WB), and outdoor ambient conditions of 95°F dry bulb (DB) and 75°F wet bulb (WB).
3. Wiring cable size must comply with the applicable local and national codes.
4. The specification may be subject to change without prior notice for purpose of improvement.
5. At least two indoor units must be connected.
6.
Combination tables with calculated SEER and HSPF are outside the scope of AHRI 1230 test standard.
*The indoor unit must be a non-ducted type.
Note:
FOR PROPER SYSTEM OPERATION:
1. At least two operable indoor units must be connected to the outdoor unit.
2. Total connected indoor unit nominal capacity must be a minimum 40% and a maximum of 133% of outdoor unit nominal capacity.
3. To calculate the connected total indoor unit nominal capacity, simply sum up the nominal capacities of all indoor units.
· For 24,000 and 36,000 Btu/h 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 smaller indoor units.
· When high static duct and/or vertical-horizontal air handling indoor units are the only connected indoor units, the multiplier is 1.2.
