Installation of the outdoor unit
WARNING
Install the outdoor unit securely in a location where the base can sustain the weight adequately.
If strength is insufficient, the unit may fall down resulting in human injury.
CAUTION
•
Drain water is discharged from the outdoor unit. (Especially while heating)
Install the outdoor unit in a place with good drainage.
•
For installation, be careful of the strength and level of the foundation so that abnormal sounds (vibration or noise)
are not generated.
REQUIREMENT
Installation in a snowfall area
1. Install the outdoor unit on a higher foundation than the snowfall or set up a stand to install the unit so that snowfall
will not affect the unit.
• Set up a stand higher than the snowfall.
• Apply an angled structure to the stand so that drainage will not be prevented. (Avoid using a stand with a
fl
at
surface.)
2. Mount a snowfall-hood onto the air inlet and the air outlet.
• Leave enough space for the snowfall-hood so that it will not be an obstacle for the air inlet and the air outlet.

1. To install multiple outdoor units, arrange them with 7.9" (200mm) (recommendation, at least 0.8" (20mm)) or more
spaces in between.
Fix each outdoor unit with M12 anchor bolts at 4 positions. 0.8" (20mm) projection is appropriate for an anchor bolt.

2. To draw out the refrigerant pipe from the underside,
set the height of the stand to 19.7" (500mm) or more.

5. Be careful of the connecting arrangement of the header unit and follower units. Set the outdoor units in order of
capacity from the one with the largest capacity. (A (Header unit)
≥
B
≥
C)
• Be sure to use a header unit for the leading outdoor unit to be connected to the main pipe. (Figure 1, 3 and 6)
• Be sure to use a T-shaped branch joint (RBM-BT14FUL/RBM-BT24FUL: separately purchased) to connect each
outdoor unit.
• Be careful of the direction of the outdoor unit connection piping kit for the liquid side. (As shown in Figure 2, an
outdoor unit connection piping kit cannot be attached so that the refrigerant of the main pipe
fl
ows directly into
the header unit.)
