FEATURES �2-stage turbo fan �

High efficiency design by 2 stage structure

+2 stage

Previous turbo fanIn the case of a conventional fan, the air outlet range was narrow as the airflow moved to the motor side which meant the velocity of air passing through the heat exchanger was uneven.

2-stage turbo fanA evenly spread air distribution across the heat exchanger is possible due to the new 2 stage turbo fan which produces two separate airflow streams.

INSTALLATION PRECAUTIONS15. INDOOR UNIT INSTALLATION PRECAUTIONS15-1.

Note: The information listed below are general precautions. Some models also include items that do not apply.

PLACES WHERE USE PROHIBITED �•Places where there is the danger of combustible gas leakage.•Places where sulfur gas, chlorine gas, acid, alkali, or other matter which effects equipment is generated•Places where there is a lot of oil splash and steam (kitchen, machinery room, etc.)•Places where machinery which generates high frequencies is used•Ocean beaches and other areas where there is a lot of salt•Places where carbon fibers and metal powder, powder, etc. suspended in the air•Installation in vehicles, ships, and other conveyances•Factory, etc. where voltage fluctuations are large

POINTS TO REMEMBER WHEN INSTALLING �(1) The set shall be installed at a place which can withstand the weight and vibration of the indoor unit(2) To allow maintenance after refrigerant piping, drain piping, and electric wiring connection and installation, provide an installation service space and an inspection port, as required. *Installation service space is shown on " DIMENSIONS ".(3) Be careful when installing the set at the following places.

[Installation precautions]

Contents Countermeasures (Reference)

When theceiling is high

If the indoor unit is installed where the installation heightgiven in the installation manual is exceeded, the temperaturedifference between the floor and ceiling of the room will belarge and the heating effect will be poor.Moreover, even if the indoor unit is installed within theinstallation height, a similar phenomena will occur wheninstalled in a room in which the doors are opened and closedfrequently and hot air circulation is obstructed by desks, chairs,etc.

(1) Switch the setting to the high ceiling mode.

(2) Install a circulator.

(3) Arrange the furniture in the room so that it does not obstruct the hot air.

When lower leveldirectly contactsthe outside air.

When the lower level of the shop and office is a warehouse,parking lot, etc., the surface temperature of the flooringwill become low and the radiation of cold from the floor willincrease.In this case, your feet will feel cold even if the roomtemperature is suitable.

When the air flow distribution is poor

When an indoor unit is installed in a position where the outletair flow will directly contact people, a draft may be felt.In addition, when there are obstructions in the path of theintake and outlet air flow, the air distribution may becomeextremely bad.

(1) Adjust the louver fins or take other measures matched to the site.

(2)Change the indoor unit outlet.

Contents Countermeasures (Reference)When inside the ceiling is high temperature and high humidity

When the indoor unit is installed where the inside of the ceiling is 30°C (86°F) RH80% or greater, the dew point temperature of the

outer perimeter may become higher than the cabinet surface temperature and moisture will condense on the surface of the cabinet and water drops may fall inside the room.

→Refer to Fig.A

In addition, the humidity may vary considerably the same as when the inside of the ceiling is close to hermetically sealed and used as the outside air intake path.

Add heat insulating material to (1) the outside of the indoor unit cabinet.*Regarding the cassette type, use of the “high humidity correspondence kit (option)” is recommended.

Strengthen the heat insulating (2) material of the refrigerant piping and drain piping also

→Refer to Fig.B

When the humidity inside the (3) ceiling changes considerably, install a ventilation port

Moist air curve Condition which requires addition of outside heat insulation

Relative humidity 80%

Dry bulb temperature 30°C (86°F)

Heat insulating material (procured at the site)

Small exposed part of copper pipe is desirable.

Fit tightly (purpose is to cover the sealant)

Binding material

To indoor unit

Heat insulation reinforcement material (procured at the site)

Contents Countermeasures (Reference)When using an external duct

When using an external duct to take in new fresh air, etc., condensation may form on the surface of the duct due to the effect of the outside air temperature and the humidity inside the ceiling.

Always perform heat insulation (1) processing.(Heat insulating material: Glass wool 25mm (31/32 in.) thick or more.)

When the remote

controller installation site is bad

If the cold or warm air blown out from the air conditioner directly contacts the thermostat section of the remote controller, the outlet temperature of the air conditioner may be

sensed and room temperature control will be different from the room temperature and “not cooled” or “not heated” or other trouble may occur.

In addition, there is the possbility that the same kind of trouble may also occur when the remote controller is effected by direct sunlight.

Install the remote controller (1) where it will not be directly exposed to the cold or hot air.

Install the remote controller (2) where it will not be directly exposed to sunlight or strong lighting

Contents Countermeasures (Reference)When installation

environment is quiet

When the wall mounting type was installed in a bedroom, living room, or other quiet place, the sound of the refrigerant flow may be sensed as noise and must be taken into accunt.

Plan installation of a model (1) with external expansion valve.

Plan installation of a branch (2) box farther from indoor unit.

Plan installation using another (3) air conditioner.

When installing duct type in ceiling chamber

system

In the case of the ceiling chamber system (duct is not installed at indoor unit inlet side and room air is sucked into the indoor

unit through the inside of the ceiling), the thermistor inside the indoor unit may not correctly detect the room temperature.

Heating operation: Room is not heated because the indoor unit is easily turned off by the thermostat. Cooling operation: Room is too cold because the indoor unit is difficult to turn off by the

thermostat.

Replace the indoor unit (1) thermistor with a Remote sensor unit (optional parts) and install the sensor where the room temperature can be correctly detected

When the outlet air is sucked in at duct type

Cooling operation does not cool the room and heating operation does not heat the room because the short circuited indoor unit is not turned on by the thermostat.

Reconsider the ventilation port (1) construction

Replace the indoor unit (2) thermistor with a Remote sensor unit (optional parts) and install the sensor where the room temperature can be correctly detected.

When using the wireless remote controller

Signals may not be received when using it in a room illuminated by an inverter fluorescent lamp.

Turn on the fluorescent lamp (1) and check if the indoor unit receives the signals from the remote controller. If the indoor unit does not receive the signals, consult an authorized service personnel.

When installing the inverter type

It may generate noise in TV sets, stereos and PCs. The inverter type should be (1) installed at a sufficient distance from these equipments.
