(a)
RLA is based on evaporating temperature –10°C, outdoor temperature 32°C DB, and suction superheat 10°C.
(b)
MSC=the maximum current during startup of the compressor. ZEAS uses only inverter compressors. MCA must be used to select the correct field
wiring size. The MCA can be regarded as the maximum running current.
(c)
MCA must be used to select the correct field wiring size. The MCA can be regarded as the maximum running current.
(d)
MFA is used to select the circuit breaker and the ground fault circuit interrupter (earth leakage circuit breaker).
(e)
FLA=nominal running current fan. Voltage range: units are suitable for use on electrical systems where voltage supplied to unit terminal is not
below or above listed range limits. Maximum allowable voltage range variation between phases is 2%.

CAUTION
It is not good for your health to expose your body to the air
flow for a long time.
CAUTION
To avoid oxygen deficiency, ventilate the room sufficiently
if equipment with burner is used together with the system.
CAUTION
Do not operate the system when using a room fumigation-
type insecticide. This could cause the chemicals to
become deposited in the unit, which could endanger the
health of those who are hypersensitive to chemicals.
