Indoor Unit
Installation
Step 4:
Connect drain hose
The drainpipe is used to drain water away from
the unit. Improper installation may cause unit
and property damage.
CAUTION
•
Insulate all piping to prevent condensation,
which could lead to water damage.
•
If the drainpipe is bent or installed
incorrectly, water may leak and cause a
water-level switch malfunction.
•
In HEAT mode, the outdoor unit will
discharge water. Ensure that the drain hose
is placed in an appropriate area to avoid
water damage and slippage.
•
DO NOT
pull the drainpipe forcefully. This
could disconnect it.
NOTE ON PURCHASING PIPES
Installation requires a polyethylene tube
(exterior diameter = 3.7-3.9cm, interior
diameter = 3.2cm), which can be obtained at
your localhardware store or dealer.
NOTE FOR NEW HOME INSTALLATION
When installing the unit in a new home, the
ceiling hooks can be embedded in advance.
Make sure that the hooks do not come loose
due to concrete shrinkage. After installing the
indoor unit, fasten the installation paper
template onto the unit with bolts to
determine in advance the dimension and
position of the opening on the ceiling.
Follow the instructions above for the
remainder of the installation.
Step 3: Drill wall hole for connective piping
1. Determine the location of the wall hole
based on the location of the outdoor unit.
2. Using a 65mm (2.5in) or 90mm(3.54in)
(depending on models )core drill, drill a
hole in the wall. Make sure that the hole
is drilled at a slight downward angle, so
that the outdoor end of the hole is lower
than the indoor end by about 12mm (0.5in).
This will ensure proper water drainage.
3. Place the protective wall cuff in the hole. This
protects the edges of the hole and will help
seal it when you finish the installation process.
CAUTION
When drilling the wall hole, make sure to
avoid wires, plumbing, and other sensitive
