Note 1: Criteria for the difference between suction and discharge temperatures
(1) Individual cooling operation
After operating for a minimum of 30 minutes in “COOL” mode, if the ΔT dry bulb temperature difference
between suction and discharge air of the indoor unit is 8°C or more, it is normal.
(2) Individual heating operation
After operating for a minimum of 30 minutes in “HEAT” mode, if the ΔT dry bulb temperature difference
between suction and discharge air of the indoor unit is 15°C or more, it is normal.
* 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 is small, then the ΔT temperature difference
is small.
* Consider that ΔT 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 Cassette type air conditioner 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).
* 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.
* Each compressor may have a different frequency as a measure against resonance.
* The temperature of the indoor heat exchanger (TC) indicates TCJ sensor temperature when cooling, and
TC2 sensor temperature when heating, respectively.
(2) Criteria for operating pressure
* Criteria after 15 minutes or more has passed since operating started.
(3) On rotations of outdoor fans
Outdoor fans may rotate slowly to control pressure when cooling with low outer air temperature or heating
with excessive load. For control content, also refer to items in Section 5, “Control Outline: Outdoor Unit,
Outdoor Fan Control.”
