Caution Sharp edges and coil surfaces are potential locations which may cause injury hazards. Avoid from being in contact with these places. INSTALLATION OF THE INDOOR UNIT Preliminary Site Survey • Electrical supply and installation is to conform to local authority's (e.g. National Electrical Board) codes and regulations.
Unit Installation 890.0 mm (Ceiling board opening) • 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 and 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.
Indoor Unit Pipe Clamp GOOD BAD • 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 20mm. • Be sure to execute heat insulation (polyethylene foam with thickness more than 8.
Control Box LED Wire From Front Panel Air Swing Wire NOTE Install the front frame panel firmly to prevent cool air leakage which will cause condensation and water dripping. Indoor Unit Cool Air Cool Air Air Leak Air Leak Ceiling Board Ceiling Board Panel Panel Bad Installation Good Installation Air intake grille installation • Before installing the air intake grille, be sure to fix the ionizer filter to the air filter.
INSTALLATION OF OUTDOOR UNIT • A place protected from rain, direct sunlight and well-ventilated wherever practicable. • A place capable of bearing the weight of the outdoor unit and isolating noise and vibration. • A place where there are no obstruction of air flow into or out the unit. • Do not put any object which may become obstacle for the air flow into or out the outdoor unit. • The location must not be susceptible to high concentration dust, oil, salt or sulfide gas.
Piping Connection • Do not use contaminated or damaged copper tubing. If any piping, evaporator or condenser had been exposed or had been opened for 15 seconds or more, then vacuum and purge with field supplied refrigerant. Generally, do not remove plastic, rubber plugs and brass nuts from the valves, fittings, tubing and coils until it is ready to connect suction or liquid line into valves or fittings.
