pan and the heat exchanger coils can remove from the unit easily by remove the bottom panel.
MICROCOMPUTER REMOTE CONTROLLER
The incorporated microprocessor give more accurate control and with the following extra features:
• Fan motor speed can be set at high/medium/low and automatic.
• Timer on/off - the unit can be pre-set to on and off automatically.
• Electronic thermostat - room temperature is precisely controlled resulting in energy saving and increase
comfort.
• Sleep mode automatically increase set temperature since room temperature is lower at night thus
achieving healthy sleep.
WIRELESS REMOTE CONTROLLER
The compact wireless remote controller makes it possible to operate the air conditioner anywhere within the
room.
AUTO OR MANUAL CONTROL ON VERTICAL AIRFLOW DIRECTION
With auto control, the louver will automatically swing up and down to create an excellent air distribution. You

PHSAE SEQUENCER
The unit with Scroll Compressor can only rotate in one direction. For this reason, a protective device (phase
sequencer) is fitted to prevent incorrect wiring of the electrical phases. When the three phases are not
connected correctly, the phase sequencer operates, and the unit will not start. This devise is located in the
control box of the outdoor unit.
The following table shows the LED indicator light for phase sequencer under normal operation and fault conditions.

INSTALLATION
Sharp edges and coil surfaces are potential injury hazard. Avoid from contact with them.
(1) INSTALLATION OF OUTDOOR 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 transformer which can cause high supply fluctuations.
•Ensure that the location is convenient for wiring, piping and drainage
STANDARD MOUNTING
Ensure that the overhead supports are strong enough to hold the weight of the unit. Position the hanger rods (wall
mounting bracket for floor standing), and check for its alignment with the unit as shown in Figure A. Also, check that
the hangers are secured and the base of the fan coil unit is leveled in both horizontal directions, taking into account
the gradient for drainage flow as recommended in Figure B.

Please ensure that the following steps are taken :
•Check the gradient for drainage flow as recommended in Figure B.
•Provide clearance for easy servicing and optimal air flow as shown in Figure C.
•The indoor unit must be installed such that there is no short circuit of the cool discharge air with the
warm return air.
•Do not install the indoor unit where there is direct sunlight shining on the unit. The location should be
suitable for piping and drainage installation. The unit must be a large distance away from the door.
SEMI-ENCLOSED MOUNTING
• In case the unit is to be half recessed into false ceiling, please check the unit is well align.
