PREPARATION BEFORE OPERATING

NOTES:
If operation is stopped, and to be restarted immediately, the unit will resume operation only after 3 minutes.

HOW TO INSERT BATTERIES

Do not use rechargeable (Ni-Cd) batteries because such batteries differ from the standard dry cell batteries in shape, dimensions and performance.

ABOUT THE BATTERIES

• The batteries can be used for approximately one year.
• Be sure to replace the batteries with two new identical batteries.
• Remove the batteries if the air conditioner will not be used for an extended period of time

OPERATION CONDITIONS

Use the air conditioner under the following conditions:

Operating temperature range.

Continuous operation at over 90% high humidity may create condensation and result in waterdrops on the intake and outlet vanes.

• Avoid installation in the following locations.
• Mechanical processing plants and other places with a lot of mechanical oil.
• High humidity areas such as laundry room and bathroom.
• Air conditioner normal operating temperature.
• In side maximum temperature 30℃
• Out side maximum temperature 43℃
• NOTICE:
  When the air conditioner is used at room temperature of 21 degrees or less, the temperature may be too low, and the air conditioner may be easily frosted. After frosting, it may be difficult to drain and may flow into the room.

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 emergency.
• Ensure that the air conditioner is well supported, securely fastened, easily reachable and not obstructed.
• Aviod location with: salty or sulphurous air, draughts, dampness and flammable gas.
• If you install the drainage system, be sure to channel the concensed 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 splash proof. You don’t need to shield or cover it.
• R32 refrigerant air conditioner installation and maintenance should be done by competent person.

PREPARATIONS BEFORE INSTALLATION

Dimension

• There should not be any obstacles surrounding the unit.
• Prepare and installation hole slightly bigger than the cabinet size.
• Left and right side of the unit should be at least 15 cm away from the wall.
• The minimum installation height is 75cm.

(Based on IEC 60335-2-40, there is no restriction for the minimum installation floor area since the refrigerant charges is less than 1.224kg

CAUTION POINT DURING INSTALLATION

When installing air conditioner at glass window or thin partition, fix the vertical and side supporting bar to the concrete wall in order to support the weight of the air-conditioner and reduce the vibration that is being transferred to the glass window or thin partition.

This can minimize the noise problem caused by improper installation.

Proposed to use 1/8” x 1-1/4” “angle-aluminium for installation frame and side supporting bar.

INSTALLATION PROCEDURES

1. Remove the rear cabinet screws and two chassis locking brackets from the cabinet. Save for later use.

2. Slide the chassis out from the cabinet.

3. Place the cabinet into the installation hole.

4. Slide the chassis into the cabinet.

CONDENSED WATER DRAINAGE

This air conditioner employs a “Slinger-Up System” which is designed to splash the condensed water on the condenser coil for maximum cooling efficiency, thus producing a splashing sound. If the splashing sound annoys you, you can provide an outside drainage by using the following the procedure which may, cause a small loss of performance.

NOTE: If the unit is installed at a coastal area, drainage of condensed water is recommended to prevent easy condenser corrosion.

1. Remove the rubber plug and chassis locking bracket from the cabinet. Then slides the chassis out from the cabinet.

2. Install the drain pan
   

3. Connect a drain hose. Fit the drain hose to the drain pan.
   Underside view with drain pan and hole in place.

NOTE
Drain hose or tubing can be purchased locally to satisfy your particular needs.

4. Slide the chassis back into the cabinet. Lock the chassis to the cabinet reusing the chassis locking bracket. Reinstall the cabinet and chassis.

NOISE CONSIDERATION

• Select an installation location that can support the weight of the air conditioner and one that will not cause increased operating noise and vibration.
• Ensure that when installed, airflow and noise from the rear side of the unit (outdoor) do not disturb neighbouring elements.
• Obstacles placed in front of the air outlet on the rear side of the unit (outdoor), or covers placed over it will cause excessive noise and deterioration in performance.

TRANSFERRING

Repositioning or transfer of the air conditioner due to renovation or moving requires an additional service charge. Please consult your dealer before moving.

• If the unit was set to TIMER mode or SLEEP mode, operation will not resume automatically.
• When power failure occurs, the timer setting is cancelled. Once power returns, reset timer.

ENERGY SAVING HINTS

• 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 reason do not overcool your room.
• Your air conditioner’ s cooling capacity should match your room size.

CARE AND MAINTENANCE

• 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.
