AIR CONDITIONER INSTALLATION
CHOOSING THE INSTALLATION LOCATION
- When installing, use the nearest power outlet. Make sure the power outlet is easy to reach so you can quickly disconnect your air conditioner in case of an emergency.
- Ensure that the air conditioner is well supported, securely fastened, easily reachable and not obstructed.
- Avoid locations with: salty or sulfurous air, draughts, dampness and flammable gas.
- If you install the drainage system, be sure to channel the condensed water to a suitable location.
- Covers, obstructions and unsteady support may cause excessive operating noise and vibration. The rear end of the air conditioner is splashproof. You don’t need to shield or cover it.
- R32 refrigerant air conditioner installation and maintenance should be done by a competent person.
**PREPARATIONS BEFORE INSTALLATION Dimension
**
- There should not be any obstacles surrounding the unit.

- Clean the air filter every 2 weeks. Regular cleaning of the air filter preserves efficiency.
- Keeping ventilation set to CLOSE closed keeps cool air in and hor air out.
- Avoid direct sunlight and heat
- For health, reasons do not overcook your room.
- Your air conditioner’s cooling capacity should match your room size.
CARE AND MAINTENANCE
Always turn off the air conditioner and the main power supply before cleaning the unit. Switch off the power supply if the unit is not going to be used for a long period of time.
- Clean the cabinet, front grille with mild soap or detergent and lukewarm water.
- The front intake grille can be easily removed for cleaning purposes (refer to Remove the front intake grille procedures). Gently wash it with water and a sponge.
- The filter can be easily cleaned using a vacuum cleaner. Vacuum the front of the filter and then wash the rear with water. If it is badly spoiled, wash with a mild household detergent.
- Do not clean with benzene, thinner, scouring powder or cloth soaked in caustic chemicals.
- If the unit is extremely dirty, heat transfer is less Efficient and the unit may not cool effectively. Contact Shun Hing Electric Service Center Ltd. for an annual check. (Annual check is not covered by the warranty.) If the air filter becomes clogged with dust, the cooling capacity will drop, and 6% of the electricity used to operate the air conditioner will be wasted.
NOTE: Do not dry the front panel or the air filter in direct sunlight.
PRE-SEASON INSPECTION
Is the discharged air cold? After 15 minutes of operation, it is normal for
the temperature difference between intake and outlet air to be more than 8°C
for cooling. Are the air intake and outlet vanes of the indoor and outdoor
side obstructed? Are the remote control batteries weak?
