1. Mount the installation plate on the wall with 5 screws or more (at least 5 screws).
(If mounting the unit on the concrete wall, consider using anchor bolts.)
o Always mount the installation plate horizontally by aligning the marking-off line with the thread and using a
level gauge.
2. Drill the piping plate hole with ø70 mm hole-core drill.
o Line according to the left and right side of the installation plate.
The meeting point of the extended line is the center of the hole.
Another method is by putting measuring tape at position as shown in the diagram above.
The hole center is obtained by measuring the distance namely 80 mm for left and right hole respectively.
o Drill the piping hole at either the right or the left and the hole should be slightly slanting to the outdoor side.

CAUTION
When the wall is hollow, please be sure to use the
sleeve for tube assembly to prevent dangers
caused by mice biting the connection cable.
4 Finish by sealing the sleeve with putty or
caulking compound at the final stage.
