3.1 System layout

INFORMATION

The following illustration is an example and might NOT match your system layout.

CAUTION

Do NOT install or use in highly airtight spaces, e.g. soundproof chambers or rooms with sealed doors.

CAUTION

This unit is equipped with electrically powered safety measures, such as a refrigerant leak detector. In order to be effective, the unit must be electrically powered at all times after installation, except for short service periods.

4.1.1 Installation site requirements of the indoor unit

INFORMATION

The sound pressure level is less than 70dBA.

▪ Use suspension bolts for installation.

▪ Mind the following requirements:

Wall-mounted type Floor-standing type

a Indoor unit

b Outdoor unit

c User interface

d Refrigerant piping + interconnection cable

e Drain pipe

f Earth wiring

4 Preparation

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.

CAUTION

Do NOT install or use in places filled with smoke, gas, chemicals etc. Sensors inside the indoor unit may detect these substances, and display a refrigerant leak abnormality.

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.

(1)

Only for units using R32 refrigerant. Refer to the outdoor unit specifications for the type of refrigerant to be used.

a Minimum clearance

a Indoor unit

▪ Install the unit with a prebuilt fully enclosed casing with removable

access panel, suction air grille and discharge grille. These removable parts shall prevent access to the unit and can ONLY be removed using a removal tool.

▪ In case of installation under a window sill, make sure that there is

no short-circuit of air.

4.2 Preparing refrigerant piping

5.1.2 Guidelines when installing the indoor unit

INFORMATION Optional equipment. When installing optional equipment,

also read the installation manual of the optional equipment. Depending on the field conditions, it might be easier to install the optional equipment first.

▪ Wall or floor strength. Check whether the wall or the floor is

strong enough to support the weight of the unit. If there is a risk, reinforce the wall or the floor before installing the unit.

▪ Suspension bolts. Use W3/8 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.

▪ Fixing the unit. Level the unit with the levelling screws

(accessory). If the floor is too uneven to level the unit, place the unit on a flat and levelled base. If the unit is in danger of falling over, fasten it to the wall using factory-made holes or to the floor using floor fasteners (field supply).

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.

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

▪ 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 20 mm nominal diameter and 26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.

a Hanging bar O Allowed X Not allowed

▪ Condensation. Take measures against condensation. Insulate

the complete drain piping in the building.

To connect the drain piping to the indoor unit

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.

Push in the plug.

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

▪ 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.

Only for units using R32 refrigerant. Refer to the outdoor unit specifications for the type of refrigerant to be used.

The R32 refrigerant (if applicable) in this unit is mildly flammable.

▪ Pipe length. Keep refrigerant piping as short as possible. ▪ Flare connections. Connect refrigerant piping to the unit using

flare connections.

▪ Insulation. Insulate the refrigerant piping on the indoor unit as

5.3 Connecting the electrical wiring

DANGER: RISK OF ELECTROCUTION

WARNING

ALWAYS use multicore cable for power supply cables.

WARNING

If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.

2 User interface cable: Route the cable through the frame,

connect the cable to the terminal block, and fix the cable with a cable tie.

3 Interconnection cable (indoor↔outdoor): Route the cable

through the frame, connect the cable to the terminal block (make sure the numbers match with the numbers on the outdoor unit, and connect the earth wire), and fix the cable with a cable tie.

4 Wrap the cables with the sealing material (accessory) to

prevent water from entering the unit. Seal all gaps to prevent small animals from entering the system.

WARNING

Provide adequate measures to prevent that the unit can be used as a shelter by small animals. Small animals that make contact with electrical parts can cause malfunctions, smoke or fire.

▪ If single-core wires are used, be sure to curl the end of the lead.

Improper work may cause heat or fire.

▪ The earth wire between the pull relief and the terminal must be

longer than the other wires.

5.3.2 To connect the electrical wiring on the indoor unit

It is important to keep the power supply and the transmission wiring separated from each other. In order to avoid any electrical interference the distance between both wiring should always be at least 50mm.
