Standard type

Note 1. If units are operated for a long time at the dew point temperature of 23˚C [73˚F] or more, condensate may collect and drip from the indoor

units. If the units are operated under such conditions, cover the entire surface of all indoor units with insulating materials with a thickness of between 0 and 20 mm [13/16 in.] to prevent condensate from collecting.

(1) Notes on using the Fresh Air Intake type units

1Fresh air intake type indoor units supply pretreated outside air into the room. This type of units are not designed to

handle internal thermal load. Use other types of air conditioning units (e.g., CITY MULTI system) that are capable of handling internal thermal load in combination with the Fresh Air Intake type units.

2The control mode is selectable between room temperature control and supply air temperature control. The default

mode is room temperature control. Install the supplied thermistor in a location that allows the sensor to measure the representative room temperature.

·Fresh air intake type units are intended to be used in an environment at a temperature of 0˚CDB

[32

˚FDB] or above. If the units are operated in the fan mode at the temperature below 0˚C[32˚F], condensation may form on the panel under certain conditions. Use caution so that the condensation will not drip on appliances around the unit.

·The unit may be forced to operate in the heating mode to prevent cold draft when the return air

temperature (outside air temperature sensor reading) reaches 5

˚C[41˚F] or below. The fan will stop during the defrost cycle and when there is a problem with the entire refrigerant systems. The fan can be set to operate in the conditions above by making certain switch settings if a sudden supply of cold air into the room during the heating season will not be a problem.

·Note that untreated outside air may be delivered directly into the room upon Thermo-OFF. Use

extra caution when the outside temperature is low. Direct exposure to outdoor air may have an adverse effect on health or cause food spoilage.

·Fresh air intake type units are not equipped with a dehumidifying function. Take appropriate

measures to keep condensation from forming on the supply air grill and other parts that are subject to condensation. Line the supply and return air ducts with insulation to prevent condensation.

Common items

Room temperature control (factory setting)

·Install the thermistor that is supplied with the indoor unit. Check that Switch 7-2 is set to OFF.

·Install the thermistor in a location that allows the sensor to measure the representative room

temperature.

·The unit will go into the forced Thermo-OFF mode when the return air dry bulb temperature

(outside air temperature sensor reading) is 21

˚C[70˚F] or below during cooling OR 20˚C[68˚F] or

above during heating.

·The settable temperature range on the remote controller is as follows: Cooling 19 - 30˚C[66 -

86

˚F]; Heating 17-28˚C[63 - 82˚F].

·Indoor temperature and humidity can fluctuate greatly depending on the outside air load.

Supply air temperature control

·Connect the connector of the supply air temperature sensor that is built in on the indoor unit to

the control board. Turn Switch 7-2 to ON.

·The unit will go into the forced Thermo-OFF mode and operate in the Fan mode when the return

air dry bulb temperature (outside air temperature sensor reading) is 14

˚C[57˚F] or below during

cooling OR 28

˚C[82˚F] or above during heating.

·Supply air temperature may fluctuate, depending on the temperature/humidity of the outside air

or on other operating conditions. Units may go in and out of the Thermo-ON/OFF mode when the following conditions are met: The difference between the outside temperature and the preset temperature is less than approximately 6

˚C[43˚F] due to excess capacity. They may change

depending on the air flow rate and preset temperature.

·Supply air temperature normally appears on the remote controller. When the unit operation is

not stable, this temperature may blink on the display and can be mistakenly interpreted as an error. If this is a problem, change the setting to suppress the temperature display. Refer to the section "How to use the remote controller" in the Instructions Manual for how to make the setting.

·The settable temperature range on the remote controller is as follows: Cooling 14 - 30˚C[57 -

86

˚F]; Heating 17-28˚C[63 - 82˚F].

·Depending on the air conditioning load, outside temperature, and due to the activation of

protection functions, the desired preset temperature may not always be achieved.

4Fan control

The unit may be forced to operate in the heating mode to prevent cold draft when the return air temperature (outside air temperature sensor reading) reaches 5

˚C[41˚F] or below. At the time of factory shipment, fan setting is made so that the fan will stop during the defrost cycle and when there is a problem with the entire refrigerant systems. See below for switch settings and unit operation.

5Sample operation patterns (supply air temperature control)

The unit will follow the operation control pattern below at the nominal air flow rate and the preset temperature of 22

˚C[72˚F]. Use it only as a guide. The range changes with the air flow rate and preset temperature.

Notes

When the return air temperature reaches 5

˚C[41˚F] or below, the unit will be forced to operate in the heating mode to prevent cold draft regardless of the actual operation mode setting. If the return air temperature reaches 6

˚C[43˚F] or above, the units will resume operation in the selected mode. The fan will stop when there is an error, regardless of the outside temperature.

Operation

OFF

ON

*Operating the fan during the defrost cycle can cause cold outside air to be delivered into the room, and it can also

delay normal unit operation to be resumed after the defrost cycle is completed, both of which can greatly decrease the room temperature.

2.When the room in which the unit is installed is airtight,

the pressure in the room may become negative.

This may result in problems such as the door to becoming difficult

Note:7

Note: 1. (Heavy dotted line): Field wiring

2. Have all electric work done by a licensed electrician according to the local regulations.

3. Earth leakage circuit breaker should be set up on the wiring of the power supply.

4. Mark indicates terminal bed, connector.

5. To enable the "auto recovery after power failure" function, set SW1-9 of both No. 1 and No. 2 circuit

boards to ON.

(Factory setting: OFF)

6. Supply air thermistor is built in on the inside of the indoor unit.

A jumper is taped inside the control box without it being connected to the connector.

Plug the jumper into CN20 on No. 1 circuit board when using the supply air temperature to control the

room temperature. Turn SW7-2 of both No. 1 and No. 2 circuit boards on the indoor unit to ON.

7. Indoor unit is supplied with a thermistor.

Install the sensor in the room to properly control the room temperature.
