Space Saving, Elegance and Prestige
The unit is installed above the ceiling with only the supply and return air grille exposed to view. This ceiling
concealed type of design has made it an “Evergreen” model without sacricing the precious oor space.
The air-conditioned space will appear as elegant and prestigious as centralized air-conditioned area but with only
a fraction of the cost. This model is ideal for small ofces, hotel rooms, hospitals and restaurant applications.
Double Proctection Drainage System
High humidity inside the ceiling area is always the main cause of water leaking. By introducing “Built In”
double drain pans solution, i.e. primary drain pan and secondary drain pan, water leaking will not be a
problem anymore. The high quality Polystyrene (PS) primary drain pan come with a layer of thermal forming
High Impact Polystyrene (HIPS) coating.
The primary drain pan is specially designed, with mould in gradient, for better condensate water drainage.
Furthermore, the drain pan is made of PS, which is a very good insulation material to prevent sweating. The
secondary drain pan will act as a drip pan to block any water that might be dripped down thus offering an
additional protection to the ceiling. In such a case, additional drain pan will not be necessary during installation
which means more cost saving. A drain socket is supplied to connect both drain pans to the drainage pipe.
Easy and Flexible Installation
The physical height of the unit is only 261mm / 378mm, it is therefore offering greatest exibility in selecting
installation location.
With its special designed installation accessories, the installation job become easy and better air distribution can be
achieved without extra spending on duct works.
Easy Maintenance
The simple design concept has a friendly maintenance and servicing in mind. Just loosening a few screws,
remove secondary drain pan and drain guide, you can access to all the internal parts from the bottom of
the unit. No water will splash down when removing the secondary drain pan makes the servicing work never
easier before.
Medium Static Pressure with a Low Noise Level
This new series has a static pressure between 0 to 15 mmAq depend on duct work installation. The casing is
well insulated internally to reduce the noise level.

Notes: 1. “-” means LED off.
2. When R phase missing, no LED or buzzer will indicate the error, but relay 71 (Common) and 81 (NO)
will cut off.
3. The unit will check the discharge sensor availability only during power up.
4. All errors can only recover through manually reset.

(1) Installation of Indoor Unit
Install the unit in such a way that
the condensate water can ow
out smoothly.
The diagrams below show the screws position for duct work connection.
Preliminary Survey
• Electrical supply and installation is to conrm to local authority’s (e.g. National Electrical Board) codes
and regulations.
• Voltage supply uctuation must not exceed ± 10% of rated voltage. Electricity supply lines must be
independent of welding transformers which can cause high supply uctuation.
• Ensure that the location is convenient for wiring, piping and drainage.
• The indoor unit must be installed in such that free from any obstacles in path of cool air discharge and
warm air return, and must allow spreading or air throughout the room (near the centre of the room).
• Clearance must be provided for the indoor unit from the wall and obstacles as shown in the gure.
• Use the hanger supplied with the unit.
• Ensure the support is strong enough to withstand the weight of the unit.
• Use the supplied drain socket to connect the drain pipe (the drain socket is only available for 10C/CR
to 25C/CR)
Caution
Sharp edges and coil surfaces are potential injury hazard. Avoid from contact with them.

21
(2) Installation of Outdoor Unit
As condensing temperature rises, evaporating temperature rises and cooling capacity drops. In order to achieve
maximum cooling capacity, the location selected for outdoor unit should fulfill the following requirements:
• Install the condensing (outdoor) unit in a way such that hot air distributed by the outdoor condensing unit
cannot be drawn in again (as in the case of short circuit of hot discharge air). Allow sufficient space for
maintenance around the unit.
• Ensure that there is no obstruction of air flow into or out of the unit. Remove obstacles which block air intake
or discharge.
• The location must be well ventilated, so that the unit can draw in and distribute plenty of air thus lowering
the condensing temperature.
• A place capable of bearing the weight of the outdoor unit and isolating noise and vibration.
• A place protected from direct sunlight. Otherwise use an awning for protection, if necessary.
• The location must not be susceptible to dust or oil mist.
Installation Clearance
•Outdoor units must be installed such that there is no short circuit of the hot discharge air or obstruction to
smooth air flow. Select the coolest possible place where intake air should not be hotter than the outside
temperature) (max. 45˚C)
CAUTION : If the condensing unit is operated in an atmosphere containing oils (including machine
oils), salt (coastal area), sulphide gas (near hot spring, oil refinery plant), such substances may lead
to failure of the unit.
