TIPS FOR SAVING ENERGY

ENGLISH

• 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.

WIRING CONNECTION

ENGLISH

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.

CONNECTING PIPES

ENGLISH

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 pur­chased locally.

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

- Cut the pipes a little longer than measured
distance.

- Cut the cable 1.5 m 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 burrs 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)

Flaring work

- Carry out flaring work using dedicated flaring
tool for R-410A as shown below.

Firmly hold copper tube in a bar(or die) as
indicated dimension in the table above.

Check

- Compare the flared work with figure below.

- If flare is noted to be defective, cut off the
flared section and do flaring work again.

Connecting the pipes to the outdoor unit

Align the center of the piping and sufficiently
tighten the flare nut by hand.

Finally, tighten the flare nut with torque
wrench until the wrench clicks.

- When tightening the flare nut with torque
wrench, ensure the direction for tightening
follows the arrow on the wrench.

Preventing foreign objects from entering

- Plug the pipe through-holes with putty or
insulation material(procured locally)to stop up
all gaps.

CONNECTING PIPES

ENGLISH

Forming the piping

Form the piping by wrapping the connecting
portion of the indoor unit with insulation mate­rial and secure it with two kinds of vinyl tape.

- If you want to connect an additional drain
hose, the end of the drain outlet should be
routed above the ground. Secure the drain
hose appropriately.

In cases where the outdoor unit is installed
below the indoor unit perform the following.

1 Tape the piping, drain hose and connecting

cable from down to up.

2 Secure the tapped piping along the exterior

wall using saddle or equivalent.

Plastic

Seal a small
opening around
the pipings with

In cases where the outdoor unit is installed
above the indoor unit perform the following.

1 Tape the piping and connecting cable from

down to up.

2 Secure the taped piping along the exterior

wall. Form a trap to prevent water entering
the room.

3 Fix the piping onto the wall by saddle or

equivalent.
