2 TIPS FOR SAVING ENERGY

TIPS FOR SAVING ENERGY

Here are some tips that will help you minimize the power consumption when you use the air conditioner. You can use your air conditioner more efficiently by referring to the instructions below:

•Do not cool excessively indoors. This may be harmful for your health and may consume more electricity.

•Block sunlight with blinds or curtains while you are operating the air conditioner.

•Keep doors or windows closed tightly while you are operating the air conditioner.

•Adjust the direction of the air flow vertically or horizontally to circulate indoor air.

•Speed up the fan to cool or warm indoor air quickly, in a short period of time.

•Open windows regularly for ventilation as the indoor air quality may deteriorate if the air conditioner is used for many hours.

•Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the air flow or weaken the cooling / dehumidifying functions.

INSTALLATION

Select the best Location

-There should not be any heat or steam near the unit.

-Select a place where there are no obstacles around of the unit.

-Make sure that condensation drainage can be conveniently routed away.

-Do not install near a doorway.

-Ensure that the interval between a wall and the left (or right) of the unit is more than 100 mm. The unit should be installed as high as possible on the wall, allowing a minimum of 200 mm from ceiling.

-Use a metal detector to locate studs to prevent unnecessary damage to the wall.

2Measure the wall and mark the centerline. It is also important to use caution concerning the location of the installation plate.

Routing of the wiring to power outlets is through the walls typically. Drilling the hole through the wall for piping connections must be done safely.

Flaring Work

Main cause for gas leakage is due to defect of flaring work. Carry out correct flaring work in the following procedure.

Cut the pipes and the cable

1Use the piping kit accessory or the pipes purchased locally.

2Measure the distance between the indoor and the outdoor unit.

3Cut the pipes a little longer than measured distance.

4Cut the cable 1.5m longer than the pipe length.

Burrs removal

1.Completely remove all burrs from the cut cross section of pipe/tube.

2.While removing burrs put the end of the copper tube/pipe in a downward direction while removing burrs location is also changed in order to avoid dropping burrs into the tubing.
