INSTALLATION
Complete Pre--installation Checks
1.
Unpack Unit
-- Store the indoor and outdoor units in the orig-
inal packaging until it is moved to the final site for installation.
When unpacking indoor unit, be careful not to lift unit by con-
densate drain discharge pipe or by refrigerant connections.
2.
Inspect Shipment
-- Upon receipt of shipment, check the in-
door and outdoor units for damage. If there is any damage,
forward claim papers directly to the transportation company.
Manufacturer is not responsible for damage incurred in transit.
3.
Inspect Parts Supplied With Units
– Check all items
against parts list (see the PARTS LIST section). If any items
are missing, notify your distributor or manufacturer office.
To prevent loss or damage, leave all parts in original pack-
ages until installation.
Consider System Requirements
1. Consult local building codes and NEC for special installa-
tion requirements.
2. When deciding the location of the indoor and outdoor units,
ensure that the piping run does not exceed the allowed dis-
tances listed in Table 9.
3. Make sure the indoor and outdoor units are easily accessible
to electrical power.
4. Allow sufficient clearances for airflow, wiring, refrigerant
piping, and servicing the unit (see the ”CLEARANCES --
INDOOR” and “CLEARANCES -- OUTDOOR” sections).
5. Condensate piping can be directed through the inside wall
to an approved drain or straight outside.
INSTALL INDOOR UNIT
Plan the installation carefully before you begin.
1. Select indoor unit location.
a. Where it is out of direct sunlight.
b. Where the airflow is not blocked.
c. Where an optimum air distribution is ensured.
d. Where the condensate can drain correctly and safely.
e. A ceiling that prevents vibration and is strong enough to
hold the product weight.
f. Maintain sufficient clearance around the indoor unit for
maintenance and servicing. Refer to the clearances sec-
tion of this document.
g. Where the air filter can be removed and cleaned easily.
h. Where the piping between the indoor and outdoor units
is within the allowable limits.
i. Install the indoor unit 1m or more away from the TV or
radio to prevent the screen from being distorted or noise
from being generated.
j. Install the indoor unit as far away as possible from fluo-
rescent and incandescent lights so that the remote con-
trol can be operated well.
k. Do not install units too close to humid conditions.
