The unit has the drainage hole at the bottom of the front side. Install the unit so that the “UP”
•
mark on the rear side points upward.
When installing the unit, do not block the drainage hole at the bottom of the front side. Even if
•
either of the front or bottom side of the unit is stuck with the order post, the drainage hole will
not be blocked. However, the hole will be blocked if both sides are stuck. When installing the
unit with the front and bottom sides close to the order post, keep a distance of 3 mm {1/8
inches} or more from the bottom side so that water can be drained. When the provided Foam
1 is used for the installation, this treatment is not required since the foam can drain the water.
The gaskets and the wind screen used for the installation may deteriorate depending on the
•
operating environment. Replace them with new ones regularly. For replacement, contact your
dealer.
