Note 1: Criteria for the difference between suction and discharge temperatures<br />
(1) Cooling operation<br />
After operating for a minimum of 30 minutes in “COOL” mode, if the T dry bulb temperature difference between<br />
suction and discharge air of the indoor unit is 8°C or more, it is normal.<br />
(2) Heating operation<br />
After operating for a minimum of 30 minutes in “HEAT” mode, if the T dry bulb temperature difference between<br />
suction and discharge air of the indoor unit is 15°C or more, it is normal.<br />
* If demand from the indoor unit on the outdoor unit is low because the difference between the temperature set<br />
by the remote controller and the temperature of the room is small, then the T temperature difference is small.<br />
* Consider that T temperature difference may diminish in cases of a system in which the connected indoor unit<br />
capacity exceeds the outdoor unit capacity, the pipe length is long, or a large difference exists among outdoor<br />
units.<br />
Note 2: Criteria for operating power current<br />
The table below shows the maximum current for each outdoor unit. Under standard conditions, operating current<br />
is about 80% of the value shown in the table below.<br />
Outdoor unit MMY-MAP 0804 1004 1204 1404 1604<br />
Current value (A) 23.5 25.5 28.5 33.2 36.5<br />
Note 3: Criteria for cycle status<br />
(1) These data are based on operating a 4-way Air Discharge Cassette type air conditioner of 100% connection<br />
with standard piping length.<br />
Data may vary depending on temperature conditions, installed pipe length, and room shape combinations, or<br />
indoor unit connection capacity.<br />
For pressure criteria in different temperature conditions, refer to (2).<br />

* This compressor is driven with a 4-pole motor. The value of the compressor frequency (rps) measured with a clamp meter at the compressor<br />
lead line is two times the rotation count (rps) of the compressor.<br />
* Each compressor may have a different frequency as a measure against resonance.<br />
* The temperature of the indoor heat exchanger (TC) indicates TCJ sensor temperature when cooling, and TC2 sensor temperature when<br />
heating, respectively.<br />

(3) On rotations of outdoor fans<br />
Outdoor fans may rotate slowly to control pressure when cooling with low outer air temperature or heating with<br />
excessive load. For control content, also refer to items in Section 5, “Control Outline: Outdoor Unit, Outdoor Fan<br />
Control.”<br />
