Notes
(1) When connecting indoor units smaller or equal to 50 class (no need to cut the outlet pipe)
(2) When connecting indoor units larger or equal to 63 class (the outlet pipe needs to be cut)
(3) Diameter when using the attached reducer. If the joint does not fit, a reducer is requested (field supply).
(4) Insulators are necessary (field supply) for the triple piping side
(5) Voltage range: units are suitable for use on electrical systems where voltage supplied to unit terminal is not below or above listed range limits.
(6) Maximum allowable voltage range variation between phases is 2%.
(7) MCA/MFA: MCA = 1.25 x FLA
(8) MFA ≤ 4 x FLA
(9) Next lower standard fuse rating minimum 15A
(10) Select wire size based on the value of MCA
(11) Instead of a fuse, use a circuit breaker

NOTES
1. Be sure to install a inspection door at electric box side. Another door is necessary to unload the product.2. Install it at the place where sound of refrigerant does not disturb. Must not install it at the space such as
roof-space of room where person exists.3. 4. In case of connecting with a 20~50 type indoor unit, there is no need to cut and connect as it is.
In case of others, cut the outlet pipe and connect to the connecting pipe. Refer to above figure.5. Reducer may be required (field supply) if joint diameter does not suit on the triple piping side.6. Insulators are necessary (field supply) for the triple piping side.7. Thas space is a space to keep a top panel when servicing.8. Install it in a place which can be secured downward slope of 1/100 or greater.9. It is a space for removing the drain pan.10. This is a space for removing a top panel when servicing.

1 This wiring diagram is for BS units only.2 The marks in this diagram indicate; : Terminal block, :
Connector, : Field wiring, : Earth terminal.3 For wiring for the terminal block X2M X3M (operation), refer to the
installation manual attached to the product.4 The factory setting of dip switch (DS1 DS2) are as follows. For the
setting method of dip switch (DS1 DS2), refer to ‘the installation manual’ and ‘precaution for service’ attached on the control box cover.
5 As for X15A(A1P), remove the short circuit connector and connect the air conditioner stop signal (optional product) when using the drain-up kit (optional product). For details, please refer to the opera-tion manual attached to the kit.

NOTES
1 The operating sound is measured in anechoic chamber. If it is measured under the actual installation conditions, it is normally over the set value due to enviromental noise and sound
2 Even if the indoor unit to be connected downstream of bs unit has stopped, when the system is operating, operating sound can be heard.
3 The maximum sound is max value of transient sound, such as oil return and defrost, the change of cooling and heating, etc.
