4.1 Preparing installation site

▪ Provide sufficient space around the unit for servicing and air

circulation.

▪ Choose the installation location with sufficient place for carrying

the unit in and out of the site.

WARNING

Do NOT install the air conditioner at any place where flammable gas may leak out. If the gas leaks out and stays around the air conditioner, a fire may break out.

a1 Nut (field supply) a2 Double nut (field supply) b1 Washer (accessories) c1 Hanger bracket (attached to the unit)

a Indoor unit b Pipe c Hanger bracket pitch (suspension) d Suspension bolt spacing

INFORMATION

▪ The fan speed of the indoor unit is preset to ensure the

standard external static pressure.

▪ To set a higher or lower external static pressure, reset

the initial setting with the user interface.

▪ Installation example:

a Anchor b Ceiling slab c Long nut or turn-buckle d Suspension bolt e Indoor unit

▪ Install the unit temporarily.

5 Attach the hanger bracket to the suspension bolt. 6 Fix it securely.

▪ Level. Make sure the unit is level at all four corners using a level

or a water-filled vinyl tube.

▪ Suspension bolts. Use M10 suspension bolts for installation.

Attach the hanger bracket to the suspension bolt. Fix it securely using a nut and washer from the upper and lower sides of the hanger bracket.

NOTICE

Do NOT install the unit tilted. Possible consequence: If the unit is tilted against the direction of the condensate flow (the drain piping side is raised), the float switch might malfunction and cause water to drip.

5.1.3 Guidelines when installing the ducting

The ducting is to be field supplied. ▪ Air inlet side. Attach the duct and intake-side flange (field

supply). For connecting the flange, use 7 accessory screws.

a Connection screw (accessory) b Flange (field supply) c Main unit d Insulation (field supply) e Aluminium tape (field supply)

▪ Filter. Be sure to attach an air filter inside the air passage on the

intake side. Use an air filter with dust collecting efficiency ≥50% (gravimetric method). The included filter is not used when the intake duct is attached.

▪ Air outlet side. Connect the duct according to the inside

dimension of the outlet-side flange.

▪ Air leaks. Wind aluminium tape around the intake side flange and

duct connection. Make sure there are no air leaks at any other connection.

▪ Insulation. Insulate the duct to prevent condensation from

forming. Use glass wool or polyethylene foam 25mm thick.

▪ Rising piping. If necessary to make the slope possible, you can

install rising piping.

▪ Drain hose inclination: 0~75mm to avoid stress on the piping

and to avoid air bubbles.

▪ Rising piping: ≤300 mm from the unit, ≤625 mm perpendicular

to the unit.

a Metal clamp (accessory) b Drain hose (accessory) c Rising drain piping (vinyl pipe of 25mm nominal diameter

and 32mm outer diameter) (field supply)

d Hanging bars (field supply)

▪ Combining drain pipes. You can combine drain pipes. Make

sure to use drain pipes and T-joints with the correct gauge for the operating capacity of the units.

5.1.4 Guidelines when installing the drain piping

Make sure condensation water can be evacuated properly. This involves:

▪ General guidelines

▪ Connecting the drain piping to the indoor unit

▪ Checking for water leaks

General guidelines

▪ Drain pump. For this "high lift type", the drainage sounds will be

reduced when the drain pump is installed in a higher location. Recommended height is 300 mm.

▪ Pipe length. Keep drain piping as short as possible. ▪ Pipe size. Keep the pipe size equal to or greater than that of the

connecting pipe (vinyl pipe of 25 mm nominal diameter and 32mm outer diameter).

▪ Slope. Make sure the drain piping slopes down (at least 1/100) to

prevent air from being trapped in the piping. Use hanging bars as shown.

NOTICE

Incorrect connection of the drain hose might cause leaks, and damage the installation space and surroundings.

1 Push the drain hose as far as possible over the drain pipe

connection.

2 Tighten the metal clamp until the screw head is less than 4mm

from the metal clamp part.

3 Check for water leaks (see To check for water leaks). 4 Install the insulation piece (drain pipe). 5 Wind the large sealing pad (= insulation) around the metal

clamp and drain hose, and fix it with cable ties.

6 Connect the drain piping to the drain hose.

▪ Condensation. Take measures against condensation. Insulate

the complete drain piping in the building.

NOTICE

▪ Do NOT remove the drain pipe plug. Water might leak

out.

▪ Use the drain outlet only to discharge the water if the

drain pump is not used or before maintenance.

▪ Insert and remove the drain plug gently. Excessive

force may deform the drain socket of the drain pan.

Pull out the plug.

▪ Do NOT wiggle the plug up and down.

Push in the plug.

▪ Set the plug and push it in using a Phillips screwdriver.

The procedure differs depending on whether electrical wiring is already finished. When electrical wiring is not finished yet, you need to temporarily connect the user interface and power supply to the unit.

When electrical wiring is not finished yet

1 Temporarily connect electrical wiring. 2 Remove the switch box cover (a). 3 Connect the single-phase power supply (50 Hz, 230 V) to

connections No. 1 and No. 2 on the terminal block for power supply and earth.

4 Reattach the switch box cover (a).
