Specifications
Notes
(1) Operation sound is measured at 1.5m below the center of the body.
(2) Air flow rate can be changed to Low mode or High mode.
(3) Normal amplitude, input and efficiency depend on the mentioned conditions.
(4) Sound values are measured in an anechoic chamber. Operating sound level generally becomes higher than this value depending on the operating conditions, reflected sound, and
peripheral noise.
(5) The noise level at the air discharge port is about 8dB higher than the operating sound of the unit.
(6) The specifications, designs and information here are subject to change without notice.
(7) Voltage range: units are suitable for use on electrical systems where voltage supplied to unit terminal is not below or above listed range limits.
(8) Maximum allowable voltage range variation between phases is 2%.
(9) MCA/MFA: MCA = 1.25 x FLA(FM1) + FLA(FM2); MFA
≤
4 x FLA; (VAM2000 is regarded as 2x VAM1000)
(10) Select wire size based on the value of MCA
(11) Instead of a fuse, use a circuit breaker
(12) MCA = 1.25 x FLA (FM1) + FLA (FM2)
(13) MCA represents maximum input current. MFA represents capacity which may accept MCA.
(14) Next lower standard fuse rating minimum 16A
