SAFETY PRECAUTIONS
Before installing the air conditioner unit, please read the following safety precautions carefully.
!Caution
Please take note of the following important points when installing.
• Do not install the unit where leakage of flammable gas may occur.
If water leaks and accumulates around the unit, it may cause fire ignition.
• Ensure that the drainage piping is connected properly.
If the drainage piping is not connected properly, it may cause water leakage which will dampen the
furniture.
• Ensure that the units panel is closed after service or installation.
Unsecured panels will cause the unit to operate noisily.

IMPORTANT
DO NOT INSTALL OR USE THE FAN COIL UNIT IN A LAUNDRY ROOM.
!Warning
• Installation and maintenance should be performed by qualified persons who are familiar with local code and
regulation, and experienced with this type of appliance.
• All field wiring must be installed in accordance with the national wiring regulation.
• Ensure that the rated voltage of the unit corresponds to that of the name plate before commencing wiring work
according to the wiring diagram.
• The unit must be GROUNDED to prevent possible hazard due to insulation failure.
• All electrical wiring must not touch the refrigerant piping or any moving parts of the fan motors.
• Confirm that the unit has been switched OFF before installing or servicing the unit.

Preliminary Site Survey
• Electrical supply and installation is to conform to local authority's (e.g. National Electrical Board) codes and regulations.
• Voltage supply fluctuation must not exceed +10% of rated voltage. Electricity supply lines must be independent of welding
transformers which can cause high supply fluctuation.
• Ensure that the location is convenient for wiring, piping and drainage.
• The indoor unit must be installed in such that is free from any obstacles in path of cool air discharge and warm air return,
and must allow spreading of air throughout the room (near the center of the room).
• Must be provide clearance for the indoor unit from the wall and obstacles as shown in the figure.
• The installation place must be strong enough to support a load 4 times the indoor unit weight to avoid amplifying noise and
vibration.
• The installation place (handing ceiling surface) must be assuring levelness and the height in the ceiling is 350 mm or more.
• The indoor unit must be away from heat and steam sources (avoid installing it near an entrance).

Unit Installation
•Measure and mark the position for the hanging rod. Drill
the hole for the angle nut on the ceiling and fix the hanging
rod.
•The installation template is extended according to
temperature & humidity. Check on dimensions in use.
•The dimensions of the installation template are the same
as those of the ceiling opening dimensions.
•Before ceiling laminating work is completed, be sure to
fit the installation template to the indoor unit.
NOTE
Be sure to discuss the ceiling drilling work with the
installers concerned.

Drain Piping Work
•Drain pipe must be in downward gradient for smooth
drainage.
•Avoid installing the drain pipe in up and down slope to
prevent reversed water flow.
•During the drain pipe connection, be careful not to exert
extra force on the drain connector at indoor unit.
•The outside diameter of the drain connection at the flexible
drain hose is 20 mm.
•Be sure to execute heat insulation (polyethylene foam with
thickness more than 8.0 mm) on the drain piping to avoid
the condensed water dripping inside the room.

Unit Hanging
•Confirm the pitch of the hanging rod.
•Hold the unit and hang it on the hanging rod with the nut
and washer.
•Adjust the unit height to 35.0 mm between the indoor unit
bottom surface and the ceiling surface.
•Confirm with a level gauge that the unit is installed
horizontally and tighten the nut and bolt to prevent unit
falling and vibration.
•Open the ceiling board along the outer edge of the paper
installation template.

Drain Test
NOTE
This indoor unit uses a drain pump for condensed water
drainage. Install the unit horizontally to prevent water
leakage or condensation around the air outlet.
Main Drain Pipe
Feed Water
Flexible
Drain Hose
•Connect the main drain pipe to the flexible drain hose.
•Feed water from flexible drain hose to check the piping
for leakage.
•When the test is completed, connect the flexible drain hose
to the drain connector on the indoor unit.
NOTE
Install the front frame panel firmly to prevent cool air
leakage which will cause condensation and water dripping.
OPEN
•Be sure to remove the installation template before install-
ing the front panel.
•Open the air intake grille by pulling back the catchers and
removing it together with filter from panel.
•Install the front frame panel onto the indoor unit by 4
screws and tighten it completely to prevent cool air leak-
age.
•Connect the LED wire and air swing wire to the indoor
unit.

Air intake grille installation
•Before installing the air intake grille, be sure to fix the
ionizer filter to the air filter.
•Install the air intake grille together with the air filter to the
front panel.
•The grille can be fit in any direction, when selecting
direction, the ceiling design and grille operability should
be considered.
•If the unit comes with ionizer filter (optional item), make
sure to fix the ionizer filter to the air filter before installing
the air intake grille.
•Fix the ionizer filter to the air filter with the black side on
top and white side at bottom.
•Carefully clip on the ionizer filter frame.
