AIR CONDITIONER INSTALLATION

CHOOSING THE INSTALLATION LOCATION

When installing, use the nearest power device. Make sure the power device is easy to reach so you can quickly disconnect your air conditioner in case of 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.

HELPFUL INFORMATION & ENERGY SAVING HINTS

HELPFUL INFORMATION

Auto Restart Control

The operation will automatically resume under the previous operation mode.
If the unit was set to TIMER mode or SLEEP mode, the operation will not resume automatically.

Timer Setting

When a power failure occurs, the timer setting is canceled. Once power returns, reset the timer.

ENERGY SAVING HINTS

Clean the air filter every 2 weeks. Regular cleaning of the air filter preserves efficiency.
Keeping ventilation set to close keeps cool air in and hot air out.
Avoid direct sunlight and heat.
For health reasons do not overcool 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 and 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 it 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 Centre 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.
Exposure to direct sunlight may discolor and deform the panel.

nanoe-G CLEAN

Turn off the power before cleaning the nanoe-G, Use a dry cotton swab for the generator needle and arc plate cleaning, and clean the generator needle up and down slightly from the left side of the middle hole.
Then, clean the arc plate left and right slightly from the left side of the lower hole.
Do not add liquids such as alcohol to dry cotton swabs.

RE-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 sides obstructed?

Are the remote control batteries weak?

The temperature difference between the blower outlet and the suction temperature under the normal state of the machine: cooling 8 or above, and heating (Heat pump model) 14 or above, is a normal phenomenon.

RECOMMENDED INSPECTION

Usage over several seasons will reduce performance as the unit becomes dirty. A dirty unit may produce foul odors and dust may clog the dehumidifying drainage. Seasonal inspection is recommended in addition to regular cleaning. Consult Shun Hing Electric Service Centre Ltd.,
