RU08/10K models are available
in two types depending on
installation conditions
RU08/10KU models are factory shipped with
refrigerant charged for 5 meters of piping.
RU08/10K models are factory shipped with no
refrigerant charged.

Reduces installation space.
Equi pped with "hi gh s ta ti c pres s ure" fan.
Long hypotenuse blades with a gentle camber make the pressure rise on the
surface of the blades smooth and uniform, while suppressing break away of
the flow. As a result, it prevents rise in draft resistance produced due to lack of
open space behind the unit, and prevents air power from dropping.
"Air Flow Adjustment Guide" (standard equipment).
Cross-section of "Air Flow Adjustment Guide".
As show in the diagram, the air flow adjustment guide is factory set
so that exhaust air flow is inclined 30 degrees. The guide can be set
to direct the air flow to the left, right or down as well as upward, so
you can adjust the direction according to the place of installation.
Outdoor units include as standard equipment the "Air Flow Adjustment
Guide" which lets you set as desired the air flow in any one of four
directions in accordance with your layout. Cushions effect of air flow
striking against obstructions in front of the unit (walls,etc.) and prevents
"short circuits" from being formed.
Anti-Corrosion treatment of heat exchange fins.
The special acrylic precoated fin (PE fin) for anti-corrosion treatment
on the outdoor unit heat exchanger ensures greater resistance against
salt damage and atmospheric pollution than ever.
R125KUYALK has been added to the list of
models capable of operating with outdoor air
temperatures of up to 54°C.
