*1 The temperature and humidity control range noted does not necessarily indicate the actual controllable range possible.
The range of control depends on the condition of the air supplied at the intake.
*2 When the intake air temperature and humidity, and outdoor ambient temperature are stable. Noted precision is based
on measurement by the internal controller at a single air outlet point.
*3 When operating according to JIS B 8616.The displayed performance will be at least 80% when the intake air
temperature of the outdoor unit is at least 35 ̊C.
*4 When operating according to JIS B 8616.The displayed performance will be at least 75 % when the intake air
temperature of the indoor unit is below 20 ̊C. The compressor will stop, and exclusive operation of the auxiliary heater
may occur if the control air intake temperature drops to approx. 15 ̊C or lower.
*5 The noted external static pressure is when the controlled air is regulated at the outlet to produce the maximum rated
processing air flow.
*6 External dimensions do not include miscellaneous protrusions such as eyebolts, etc.
*6 Maximum value within the range of unit specifications. Starting current is equal to or less than the operating current.
*7 The figure noted is when the equipment is operating at the highest level of humidification operating at the highest
capacity of its normal operating range.
*8 Source voltage phase unbalance should be less than ±3%.
*9 Maximum value within the range of product specifications.
*10 The figure noted is when the product is operating at the highest capacity of its normal operating range.
*11 Measured value (A scale) when operating at the rated processing air flow, at a position of non-resonance, 1 m from
the front face of the indoor unit, and at 1 m from the front face of the outdoor unit, at a height of 1.5 m.
*12 Blower fan output cannot be increased.
*13 Use the measured temperature and humidity bias function to correct any error between the temperature and humidity
shown on the control panel and the user's measured temperature and humidity.
Note 1: This product does not detect electrical shorts and does not have a protection function against them. An earth
leakage breaker must be installed on the primary side of the power supply.
Note 2: All ducting should be insulated and ducting length should be kept as short as possible. (5 m or shorter
