INSTALLATION PLACES

ENGLISH

- If an awning is built over the unit to prevent direct sunlight or rain exposure, make sure that heat radiation from the condenser is not restricted.

- Ensure that the spaces indicated by arrows around front, back and side of the unit are respected.

- Do not place animals and plants in the path of the warm air.

- Take the air conditioner weight into account and select a place where noise and vibration are minimum.

- Select a place so that the warm air and noise from the air conditioner do not disturb neighbors.

- Select a place that can sufficiently endure the weight and vibration of the outdoor unit and where even installation is possible.

- Select a place that has no direct impact of snow or rain

- Select a place with no danger of snowfall or icicle drop

- Select a place without weak floor or base such as decrepit part of the building or with a lot of snow accumulation

- Install at a place with fluent water draining to prevent damage from localized heavy rain and avoid frequent flooded area.

You need to select adequate installation location considering the following conditions, and make sure to acquire the consent of the user.

Installation Places for Outdoor Unit

More than 300 mm

A > 200 mm

Be very careful while carrying the product.

• Do not have only one person carry product if it is more than 20 kg (44 lbs).

• PP bands are used to pack some products. Do not use them as a mean for transportation because they are dangerous.

• Do not touch heat exchanger fins with your bare hands. Otherwise you may get a cut in your hands.

• Tear plastic packaging bag and scrap it so that children cannot play with it. Otherwise plastic packaging bag may suffocate children to death.

• When carrying in Outdoor Unit, be sure to support it at four points. Carrying in and lifting with 3-point support may make Outdoor Unit unstable, resulting in a fall.

• Use 2 belts of at least 8 m (26.2 ft) long.

• Place extra cloth or boards in the locations where the casing comes in contact with the sling to prevent damage.

•

Hoist the unit making sure it is being lifted at its center of gravity.

INSTALLATION PLACES

ENGLISH

Sea wind

• Air conditioners should not be installed in areas where corrosive gases, such as acid or alkaline gas, are produced.

• Do not install the product where it could be exposed to sea wind (salty wind) directly. It can result corrosion on the product. Corrosion, particularly on the condenser and evaporator fins, could cause product malfunction or inefficient performance.

• If outdoor unit is installed close to the seaside, it should avoid direct exposure to the sea wind. Otherwise it needs additional anticorrosion treatment on the heat exchanger.

CAUTION

- It should be strong enough like concrete to prevent the sea wind from the sea.

- The height and width should be more than 150 % of the outdoor unit.

- More than 70 cm of space should be kept between outdoor unit and the windbreak for easy air flow.

Place with fluent water draining

- Install at a place with fluent water draining to prevent damage from localized heavy rain and avoid frequent flooded area.

Seasonal Wind and Cautions in Winter

- Sufficient measures are required in a snow area or severe cold area in winter so that product can operate well.

- Get ready for seasonal wind or snow in winter even in other areas.

- Install a suction and discharge duct not to let in snow or rain.

- Install the outdoor unit not to come in contact with snow directly. If snow piles up and freezes on the air suction hole, the system may malfunction. If it is installed at snowy area, attach the hood to the system.

- Install the outdoor unit at the higher installation console by 50 cm than the average snowfall (annual average snowfall) if it is installed at the area with much snowfall.

- Where snow accumulated on the upper part of the Outdoor Unit by more than 10 cm, always remove snow for operation.

In case, to install the outdoor unit on the seaside, set up a windbreak not to be exposed to the sea wind.

In case, to install the outdoor unit on the seaside, set If the outdoor unit is to be installed close to the seaside, direct exposure to the sea wind should be avoided.

Install the outdoor unit on the opposite side of the sea wind direction. a windbreak not to be exposed to the sea wind.

Selecting the location (Outdoor Unit)

• Periodic ( more than once/year ) cleaning of the dust or salt particles stuck on the heat exchanger by using water.

Installation Guide at the Seaside

THE INDOOR UNIT INSTALLATION

ENGLISH

CAUTION

• This air-conditioner uses a drain pump.

• Install the unit horizontally using a level gauge.

• During the installation, care should be taken not to damage electric wires.

- Select and mark the position for fixing bolts and piping hole.

- Decide the position for fixing bolts slightly tilted to the drain direction after considering the direction of drain hose.

- Drill the hole for anchor bolt on the wall.

NOTE

Avoid the following installation location.

1 Such places as restaurants and kitchen where

considerable amount of oil steam and flour is generated. These may cause heat exchange efficiency reduction, or water drops, drain pump mal-function. In these cases, take the following actions;

- Make sure that ventilation fan is enough to cover all noxious gases from this place.

- Ensure enough distance from the cooking room to install the air conditioner in such a place where it may not suck oily steam.

2 Avoid installng air conditioner in such places

where cooking oil or iron powder is generated.

3 Avoid places where inflammable gas is

generated.

4 Avoid place where noxious gas is generated. 5 Avoid places near high frequency generators.
