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 to 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.

Precautions when laying power wiring
Use round pressure terminals for connections to the power terminal block.

When none are available, follow the instructions below.
-Do not connect wiring of different thicknesses to the power terminal block. (Slack in the power wiring may cause abnormal heat.)
-When connecting wiring which is the same thickness, do as shown in the figure below.
-For wiring, use the designated power wire and connect firmly, then secure to prevent outside pressure being exerted on the terminal block.
-Use an appropriate screwdriver for tightening the terinal screws. A screwdriver with a small head will strip the head and make proper tighterning impossible.
-Over-tightening the terminal screws may break them.

! CAUTION
•The circuit diagram is not subject to change without notice.
•Be sure to connect wires according to the wiring diagram.
•Connect the wires firmly, so that They won’t be pulled out easily.
•Connect the wires according to color codes by referring the wiring diagram.
•The Power cord connected to the unit should be selected according to the specifications.
CONNECTING PIPES 13
CONNECTING PIPES
Preparation of Piping
Main cause of gas leakage is defect in flaring work. Carry out correct flaring work in the following procedure.
Cut the pipes and the cable. |
|
- Use the accessory piping kit or the pipes pur- |
|
chased locally. |
Copper |
- Measure the distance between the indoor |
tube |
and the outdoor unit. |
|
- Cut the pipes a little longer than measured |
|
distance. |
|
- Cut the cable 1.5 m(4.9 ft) longer than the |
|
pipe length. |
|
Burrs removal
-Completely remove all burrs from the cut cross section of pipe/tube.
-Put the end of the copper tube/pipe to downward direction as you remove burrs in order
to avoid to let chips drop in the tubing.
Putting nut on
- Remove flare nuts attached to indoor and outdoor units, than put them on pipe/tube having completed burr removal.
(Not possible to put them on after flaring work)
