MANUAL OPERATION Manual operation can be used temporarily in case you can not find the remote controller or its batteries are exhausted. 1 Open and lift the front panel up to an angle at which it remains fixed with a clicking sound. 2 Press the button until the AUTO indicator is lit, the unit will work in forced AUTO mode. 3 Close the panel firmly to its original position. Panel CAUTIONS • • • • Once you push the manual button, the operation mode is shifted in an order as: AUTO, COOL, OFF.
OPTIMAL OPERATION To achieve optimal performance, please note the following: • Adjust the air flow direction correctly so that it is not directed on people. • Adjust the temperature to achieve the highest comfort level. Do not adjust the unit to excessive temperature levels. • Close doors and windows on COOL or HEAT modes, or performance may be reduced. • Use TIMER ON button on the remote controller to select a time you want to start your air conditioner.

INSTALLATION PROCEDURE INDOOR UNIT ■ Fixing • • Place the installation guide pattern on the designated installation place and mark the hole position. Drill a hole and mount installation plate. • Make 6 mm 4-6 holes, in the wall at the four corners of mounting plate (bracket) then insert appropriate mounting devices. • Install the mounting plate using 4-6 pieces of mounting screw securely at four corners and tighten the screw completely. Do not over tighten the screws and deform the back plate.
■ Drain hose • Drain hose is flexible and can be routed to suit various piping arrangements. The drain line must include elbow trap (U bend). Connect a plastic condensate pipe with an internal diameter of 12 mm. For right connection Drain hose Drain cap Verification of condensate water drainage: Note: Do not put the drain hose end into water. • Fill the drain pan with water and observe evacuation. The drain hose can be connected to the left or the right side.
OUTDOOR UNIT ■ Fixing and Piping • • • • • • • Piping must be performed by qualified personnel according to good refrigeration systems practices. Piping materials and insulation materials must be of refrigerant quality. Select the pipe diameters according to the size of unit and cut the pipe to design length by using pipe cutter. Install the flare nuts and flare the end of the pipes. Check that no foreign bodies are inside the piping. Align the central of the connecting pipes and tighten the flare nut.
COLD AREA RECOMMENDATION - Outdoor heat pump unit : install the unit at least 10 cm above ground level to facilitate drainage of defrost water and prevent accumulation of ice. In effect, defrost water can cause accumulation of ice under the unit during subfreezing outdoor temperatures. - In areas with heavy snowfall, it is best to install the unit on wall supports.
■ Electrical Connections All electrical wiring and connections must comply with local codes and standards. Power supply cord and interconnection cord used must not be lighter than Polychloroprene sheeted cord (245 IEC 57 or H05RN-F). Disconnecting device must have a contact separation of at least 3 mm.

Condition to start defrosting: Units will switch to defrosting mode when either of the following conditions is met.
MAINTENANCE WARNING Household Drain Cleaner It is necessary to stop the air conditioner and disconnect the power supply before cleaning. No ■ Cleaning the indoor unit and remote controller CAUTION Thinner • Use a dry cloth to wipe the indoor unit and remote controller. • A cloth dampened with cold water may be used on the indoor unit if it is very dirty. • The front panel of the indoor unit can be removed and cleaned with water. Then wipe it with a dry cloth.
OPERATION TIPS The following events may occur during normal operation. 1. Protection of the air conditioner. Compressor protection • The compressor cannot restart for 3 minutes after it stops. Anti-cold air (Cooling and heating models only) • The unit is designed not to blow cold air on HEAT mode, when the indoor heat exchanger is in one of the following three situations and the set temperature has not been reached. A) When heating has just starting. B) Defrosting. C) Low temperature heating.
TROUBLE SHOOTING GUIDE Problem Probable cause Remedy A. The air conditioner does not run. 1. Power Failure. 2. Fuse blown or circuit breaker open. 3. Voltage is too low. 4. Faulty contactor or relay. 5. Electrical connections loose. 6. Thermostat adjustment too low (in heating mode) or too high (in cooling mode) 7. Faulty Capacitor 1. Wait for Power resume. 2. Replace the fuse or reset the breaker. 3. Find the cause and fix it. 4. Replace the faulty component. 5. Retighten the connection. 6.
