Notes
(1) In case of connecting with a 15-50 type indoor unit, use the accessory pipe to match the size of the field pipe. Be sure to braze the connection between the accessory pipe and the
field pipe.
(2) Voltage range: units are suitable for use on electrical systems where voltage supplied to unit terminal is not below or above listed range limits.
(3) Maximum allowable voltage range variation between phases is 2%.
(4) MCA/MFA: MCA = 1.25 x FLA
(5) MFA ≤4 x FLA
(6) Next lower standard fuse rating minimum 15A
(7) Select wire size based on the value of MCA
(8) Instead of a fuse, use a circuit breaker
(9) In case of connecting to a 150-160 type indoor unit, use the accessory pipe to match the size of the field pipe. Be sure to braze the connection between the accessory pipe and
the field pipe.
(10) In case of connecting to a 160-200 type indoor unit, use the accessory pipe to match the size of the field pipe. Be sure to braze the connection between the accessory pipe and
the field pipe.
