CAUTION
• Remove the knockout plate on the bottom frame. (See the installation manual attached to the outdoor unit)
• Connect the gas and liquid pipe as shown in the figure below. (When connecting the pipes, first connect the gas-side joint and the gas-side
reducer (1), the liquid-side joint and the liquid-side reducer (1)).
• See the caution section in the installation manual attached to the outdoor unit for brazing pipes and connecting pipes with flare nuts.
• Install the joint in such a way that the attached face of the caution label becomes horizontal. (See the view A)
• Connect the liquid side reducer (1) tilting approx. 10° and bend the field supplied liquid pipe up to the stop valve as shown in the figure below.
(See the view A)
• If the liquid side reducer is connected vertically without bending the liquid pipes, the insulation will not fit.
