44 Service & Maintenance Service and Maintenance Warning Disconnect from main supply before servicing the air conditioner. The unit is designed to give long life operation with minimum maintenance required. However, it should be regularly checked and the following items should be given due attention. Components Maintenance Procedures Period Air Filter (Indoor Unit) Indoor Unit Condense Drain Pan & Pipe 1. Remove any dust adhering to the fi lter by using a vacuum cleaner or wash in lukewarm water (below 40 C) with a neutral cleaning detergent. 2. Rinse the fi lter well and dry before placing it back onto the unit. 3. Note: Never use gasoline, volatile substances or chemicals to clean the fi lter. 1. Clean any dirt or dust on the grille or panel by wiping it with a soft cloth soaked in lukewarm water (below 40 C) and a neutral detergent solution. 2. Note: Never use gasoline, volatile substances or chemicals to clean the indoor unit. 1. Check the cleanliness and clean it if necessary. 2. Check the condensate water fl ow. At least once every 2 weeks. More frequently if necessary. At least once every 2 weeks. More frequently if necessary. Every 3 months. Indoor Fan Check if there is any abnormal noise. If necessary. Indoor / Outdoor 1. Check and remove the dirt between the fi ns. Every month. Coil 2. Check and remove any obstacles which hinder air fl ow through the indoor or outdoor. Power Supply 1. Check the running current and voltage for indoor and outdoor unit. 2. Check the electrical wiring and tighten the wire onto the terminal Every 2 months. Every year. block if necessary. Compressor No maintenance needed if refrigerant circuit remains sealed. However, check for refrigerant leak at joint and fi tting. Every 6 months. Indoor Models 1. Open the front panel Hold the panel at the recesses on the main unit (2 recesses on right and left sides) and lift it until it stops. Recess on main unit 2. Remove the front panel While lifting the front panel further, slide it to the right and pull it to the front side. The left rotating shaft is detached. Slide the right rotating shaft to the left and pull it to the front side to remove it. Rotating shaft 3. Attach the front panel Align the right and left rotating shafts of the front panel with the grooves and push them all the way in. Gently close the front panel. (Push both ends and the center on the front panel.) Caution Don t touch the metal parts of the indoor unit. It may cause an injury. When removing or attaching the front panel, use a robust and stable stool and watch your steps carefully. When removing or attaching the front panel, support the panel securely with hand to prevent from it falling. For cleansing, do no use hot water above 40 C, benzene, gasoline, thinner, nor other volatile oils, polishing compound, scrubbing brushes, nor other hand stuff. After cleaning, make sure that the front panel is securely fi xed. 45

45 Service & Maintenance Pre Start Up Maintenance (After Extended Shutdown) Inspect thoroughly and clean indoor and outdoor units. Clean or replace air fi lters. Clean condensates drain line. Clean clogged indoor and outdoor coils. Check fan imbalance before operation. Tighten all wiring connections and panels. Check for refrigerant leakage. Outdoor Models The design of the M5LC outdoor series allows servicing to be carried out easily. The removal of the top, front and side panels makes almost every part accessible. Under normal circumstances, these outdoor units only require a check and cleaning of air intake coil surface once every 3 months. However, if a unit is installed in areas subjected to much oil mist and dust, the coils must be regularly cleaned by qualifi ed Air Conditioner Service Technicians to ensure suffi cient heat exchange and proper operation. Otherwise, the systems life span may be shortened. Caution Do not charge OXYGEN, ACETYLENE OR OTHER FLAMMABLE and poisonous gases into the unit when performing a leakage test or an airtight test. These gases could cause severe explosion and damage if exposed to high temperature and pressure. It is recommended that only nitrogen or refrigerant be charged when performing the leakage or airtight test. 46
