
The installation service spaces shown in the illustrations are based on an air intake temperature of 35 °C(DB) for
COOL operation . In regions where the air intake temperature regularly exceeds 35°C(DB), or if the heat load of
outdoor units is expected to regularly exceed the maximum operating capacity, reserve a larger space than that
indicated at the air intake side of units .

Regarding the required air outlet space, position the units with consideration to the space required for the onsite
refrigerant piping work as well . Consult your dealer if the work conditions do not match those in the drawings .
Drain pipe disposal

Make sure the drain works properly .

In regions where buildups of snow can be expected, the accumulation and freezing of snow in the space
between the heat exchanger and external plate may lower operating efficiency .

After punching the knock-out hole, the application of repair-type paint on the surface around the edge sections is
recommended to prevent rust .
