4. Utilization in Cold Area
(1) In a snow area, water from the heat exchanger may be frozen on the surface of the bottom base. This
may lead to poor drainage. Therefore, do not use the drain adaptor in this type of area.
(2) In the drainage method according to this manual, some of the defrost drain water dripped from the inlet
protection grille may
fl
ow out over the bottom base of the product.
To prevent this, provide a drain pan larger than the bottom surface of the product. Secure the drain pan
and the discharge pipe between the bottom part of the product and the foundation prior to discharge.

3.1 Installation of Drain Adaptor
The drain adaptor is for the drain pipe connection so as to use the
outdoor unit bottom base as a drain pan.
(1) Put the
2
rubber cap in the
1
drain adaptor (to the upper part
of the drain adaptor projection) in the direction of the arrow.
(2) Put the drain adaptor in the hole for the drain adaptor of the
outdoor unit bottom base until it is securely
fi
xed. (approx. 40
o
)
(The drain adaptor can be
fi
t into the bottom base until it stops.)
3.2 Installation of Drain Cap
The drain cap is a component to cover a hole.
(1) Put the
2
rubber cap in the
3
drain cap (to the upper part of
the drain adaptor projection) in the direction of the arrow.
(2) Put the drain cap in the hole for the drain adaptor of the
outdoor unit bottom base until it is securely
fi
xed. (approx. 40
o
)
(The drain cap can be
fi
t into the bottom base until it stops.)
Do not use the drain adaptor in an area where drain water may be frozen.
(The drain water in the drain pipe may be frozen and then the drain pipe may crack.)
Use a rubber cap when
fi
xing the drain adaptor and drain cap. (No rubber cap may lead to water leakage.)
After
fi
xing, ensure that there is no water leakage from the drain cap by pouring water into the bottom base
and then draining it from the drain adaptor.
Securely
fi
x the drain adaptor, rubber cap and drain cap at the bottom base so it desn’t become loose when
connecting the drain pipe.
