Note 1: Criteria for the difference between suction and discharge temperatures, between water
inlet and water outlet temperature
(1) Cooling operation
After operating for a minimum of 30 minutes in “COOL” mode, if the 'T dry bulb temperature difference
between suction and discharge air of the indoor unit is 8°C or more, it is normal.
(2) Heating operation
After operating for a minimum of 30 minutes in “HEAT” mode, if the 'T dry bulb temperature difference
between suction and discharge air of the indoor unit is 15°C or more, it is normal.
After operating for a minimum of 30 minutes in “HEAT” mode, if the 'T water temperature difference between
water inlet and water outlet of the hot water module is 3 to 5 degrees, it is normal. (Hot water module)
* If demand from the indoor unit on the outdoor unit is low because the difference between the temperature
set by the remote controller and the temperature of the room or the difference between the temperature
set by the remote controller and the water inlet temperature is small, then the 'T temperature difference is
small.
* Consider that 'T temperature difference may diminish in cases of a system in which the connected indoor
unit capacity exceeds the outdoor unit capacity, the pipe length is long, or a large difference exists among
outdoor units.
Note 2: Criteria for operating power current
The table below shows the maximum current for each outdoor unit. Under standard conditions, operating
current is about 80% of the value shown in the table below.
Note 3: Criteria for cycle status
(1) These data are based on operating a 4-way Air Discharge Cassette type air conditioner including Hot Water
Module 1 unit of 100% connection with standard piping length.
Data may vary depending on temperature conditions, installed pipe length, and room shape combinations,
or indoor unit connection capacity.
For pressure criteria in different temperature conditions, refer to (2).

*1 This compressor is driven with a 4-pole motor. The value of the compressor frequency (rps) measured with a clamp meter at the compressor
lead line is two times the rotation count (rps) of the compressor.
