Notes
(1) Cooling: indoor temp. 27ºCDB, 19ºCWB; outdoor temp. 35ºCDB; equivalent piping length: 7.5m; level difference: 0m
(2) Heating: indoor temp. 20ºCDB; outdoor temp. 7ºCDB, 6ºCWB; equivalent refrigerant piping: 7.5m; level difference: 0m
(3) The sound pressure values are mentioned for a unit installed with rear suction.
(4) The sound power level is an absolute value indicating the power which a sound source generates.
(5) Capacities are net, including a deduction for cooling (an addition for heating) for indoor fan motor heat.
(6) The BYCQ140CW1W has white insulations. Be informed that formation of dirt on white insulations is more visible and that it is consequently not advised to install the
BYCQ140W1W decoration panel in environments exposed to concentrations of dirt.
(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
(10) MFA ≤4 x FLA
(11) Next lower standard fuse rating minimum 16A
(12) Select wire size based on the value of MCA
(13) Instead of a fuse, use a circuit breaker
