Installation Manual For Wire Controller

5. Wiring connections of wire controller:
There are three methods to connection wire controller and the indoor units:
A.One wired controller can control max. up to 16 sets of indoor units, and 3 pieces of polar wire must connect the wire controller and the master unit (the indoor unit connected with wire controller directly), the others connect with the master unit through 2 pieces of polar wire
B. One wire controller controls one indoor unit, and the indoor unit connects with the wire controller through 3 pieces of polar wire.
C. Two wired controllers control one indoor unit. The wire controller connected with indoor unit is called master one, the other is called slave one. Master wire controller and indoor unit; master and slave wire controllers are all connected through 3 pieces of polar wire.
6. Communication wiring:
The wire controller is equipped with special communication wiring in the accessories. 3-core terminal (1-white 2-yellow 3-red) is connected with the terminal A, B, C of wire controller respectively. The communication wiring is 5 meter long; if the actual length is more than it, please distribute wiring according to below table:

WIRED CONTROLLER & INDOOR PCB CONNECTION(one for one wiring type):

Note: When do the wired controller & indoor PCB wiring work ,do not connect the shielded wired to the unit’s shell,do not parallel wiring with strong electric lines within 0.3 meters, please keep strong lines and the signal lines separately.

Heating Mode

“HOT KEEP” function
“HOT KEEP’ is operated in the following cases.

• When heating is started:
  In order to prevent blowing out of cool wind, the indoor unit fan stopped according to the room temperature which heating operation is started. Wait for approx. 2 to 3 minute, and the operation will be automatically changed to the ordinary heating mode.

• Defrosting operation (in the heating mode):
  When it is liable to frost, the heating operation is stopped automatically for 5 to 12 minutes once per approx. one hour, and defrosting is operated. After defrosting is completed, operation mode is automatically changed to ordinary heating operation.

• When the room thermosiat is actuated:
  When room temperature increases and room temperature controller actuates, the fan speed is automatically changed to stop under low temperature condition of indoor heat exchanger. When room temperature decreases, air conditioner automatically changes over to ordinary heating operation. :

Warming operation

• Heat pump type warming
  With the heat pump type warming, the mechanism of heat pump that concentrate heat of outdoor air with the help of refrigerant to warm the indoor space, is utilized.

• Defrosting operation
  When a room is warmed with a heat pump type air conditioner, frost accumulates on the heat exchanger of outdoor unit along with the drop of indoor temperature. Since the accumulated frost reduces the effect of warming, it is necessery to automatically switch the operation to the defrosting mode. During the defrosting operation, heating operation is interrupted.

• Atmospheric temperature and warming capacity
  Wamming capacity of heat pump type air conditioner decreases along with the drop of outdoor temperature.
  When the warming capacity is not sufficient, it is recommended to use another heating implement.

• Period of warm-up
  Since the heat pump type air conditioner employs a method to circulate warm winds to warm the entire space of a room, it takes time before the room temperature rises.
  It is recommendable to start the operation a little earlier in a very cold moming.

Care and Maintenance

Points to observe Turn off the power supply switch. Do not touch with wet hand. Do not use hot water or volatile liquid.

Points to observe

Turn off the power supply switch.| Do not touch with wet hand.| Do not use hot water or volatile liquid.

CAUTION

• Do not open the inlet grill until fan stops completely.
• Fan will continue rotating for a while by the law of inertia after operation is being stopped.

Cleaning the air filter

1. Clean the air filter by lightly tapping it or with the cleaner. It is more effective to clean the air filter with water. If the air filter is very dirty, dissolve neutral detergent in the lukewarm water (approx. 30°C), rinse the air filter in the water, and thoroughly wash the air filter off the detergent in the plain water.
2. After drying the air filter, set it up on the air conditioner.

CAUTION

• Do not dry the air filter with fire.
• Do not run the air conditioner without the air filter.

Care and Cleaning of the unit

• Clean with soft and dry cloth.
• If it is very dirty, dissolve neutral detergent in the lukewarm water and make the cloth wet with the water. After wiping, clean off the detergent using clean water.

Post-Season Care

• Operate the unit with FAN mode on a fair day for about half a day to dry the inside of the unit well.
• Stop operation and turn off the power supply switch. Electric power is consumed even the air conditioner is in stop.
• Clean the air filter and set it in the place.

Pre-Season Care

• See that there are no obstacles blocking the air inlet and air outlet of both indoor and outdoor units.
• Make sure that the air filter is not dirty.
• Cut in the power supply switch 12 hours before starting run.

Troubleshooting

Please check the following things about your air conditioner before making a service call.

Unit fails to start

Is the power source switch adjust cut in? Power supply switch is not ON.| Is city supply power in normal?| Isn’t the signal receiving section exposed to the direct sunlight or strong illumination?| Isn’t the earth leakage breaker in action?
It is dangerous. Turn off the power supply switch immediately and contact the sales dealer.
Cooling or heating is not sufficient

Is the thermostat adjust as required?| Isn’t the air filter dirty?| Isn’t any doors or windows left open?| Doesn’t any obstacle exist at the air inlet or outlet?
Cooling is not sufficient

Isn’t sun-shine invading direct?| Isn’t any unexpected heating load generated?| Isn’t the room much crowded?| The wind does not blow during heating operation
Isn’t it warming up?

When the air conditioner does not operate properly after you have checked the above mentioned items or when the following phenomenon is observed, stop the operation of the air conditioner and contact your sales dealer.

• The fuse or breaker often shuts down.
• Water drops off during cooling operation.
• There is a irregularity in operation or abnormal sound is audible.
• When the CHECK LED (red) flickers, an irregularity has occurred in the air conditioner.

The followings are not malfunction

Water flowing sound is heard.| When the air conditioner is started, when the compressor starts or stops during operation or when the air conditioner is stopped, it sometimes sounds “shuru shuru” or “gobo gobo”. It is the flowing sound of the refrigerant, and it is not a trouble.
---|---
Cracking sound is heard.| This is caused by heat expansion or contraction of plastics.
It smells.| Air which blows out from the indoor unit sometimes smells. The smell results from residents of tobacco smoke or cosmetics stuck inside of unit.
During operation, white fog comes out of indoor unit.| When the air conditioner is used at restaurant etc. where dense edible oil fume is always exists, white fog sometimes blows out of air outlet during operation. In this case consult sales dealer for cleaning the heat exchanger.
It is switched into the FAN mode during cooling.| To prevent frost from being accumulated on the indoor unit heat exchanger, it is sometimes automatically switched to the FAN mode,but it will soon return to the cooling mode.
The air conditioner can not be restarted soon after it stops.| Even if the operation switch is turned on, cooling, dehumidifying or heating is not operable for three minutes after the conditioner is stopped. Because the protecting circuit is activated. (During this time air conditioner operates in fan mode.)
Air does not blow or the fan speed can not be changed during dehumidifying.| When it is excessively cooled during dehumidifying, the blower automatically repeats reducing and lowering the fan speed.
During operation, operation mode has changed over automatically.| Isn’t the AUTO mode selected?
In the case of AUTO mode, operation mode is changed automatically from cooling to heating or vise-versa according to the room temperature.
Water or steam generates from the outdoor unit during heating.| This results when frost accumulated on the outdoor unit is removed (during defrosting operation).

Precaution for Installation

• Please read these “Safety Precautions” first and then accurately execute the installation work.
• Though the precautionary points indicated herein are divided under two headings, 4 WARNING and 4&4 CAUTION, those points which are related to the strong possibility of an installation done in error resulting in death or serious injury are listed in the 4 WARNING section. However, there is also a possibility of serious consequences in relationship to the points listed in the 4 CAUTION section as well. In either case, important safety related information is indicated, so by all means, properly observe all that is mentioned.
• After completing the installation, along with confirming that no abnormalities were seen from the operation tests, please explain operating methods as well as maintenance methods to the user (customer) of this equipment, based on the owner’s manual. Moreover, ask the customer to keep this sheet together with the owner’s manual.

WARNING

• This system should be applied to places as office, restaurant, residence and the like. Application to inferior environment such as engineering shop could cause equipment malfunction.
• Please entrust installation to either the company which sold you the equipment or to a professional contractor. Defects from improper installations can be the cause of water leakage, electric shocks and fires.
• Execute the installation accurately, based on following the installation manual. Again, improper installations can result in water leakage, electric shocks and fires.
• When a large air-conditioning system is installed to a small room, it is necessary to have a prior planned countermeasure for the rare case of a refrigerant leakage, to prevent the exceeding of threshold concentration. In regards to preparing this countermeasure, consult with the company from which you perchased the equipment, and make the installation accordingly. In the rare event that a refrigerant leakage and exceeding of threshold concentration does occur, there is the danger of a resultant oxygen deficiency accident.
• For installation, confirm that the installation site can sufficiently support heavy weight. When strength is insufficient, injury can result from a falling of the unit.
• Execute the prescribed installation construction to prepare for earthquakes and the strong winds of typhoons and hurricanes, etc. Improper installations can result in accidents due to a violent falling over of the unit.
• For electrical work, please see that a licensed electrician executes the work while following the safety standards related to electrical equipment, and local regulations as well as the installation instructions, and that only exclusive use circuits are used. Insufficient power source circuit capacity and defective installation execution can be the cause of electric shocks and fires.
• Accurately connect wiring using the proper cable, and insure that the external force of the cable is not conducted to the terminal connection part, through properly securing it. Improper connection or securing can result in heat generation or fire.
• Take care that wiring does not rise upward, and accurately install the lid/service panel. Its improper installation can also result in heat generation or fire.
• When setting up or moving the location of the air conditioner, do not mix air etc. or anything other than the designated refrigerant R32 within the refrigeration cycle. Rupture and injury caused by abnormal high pressure can result from such mixing.
• Always use accessory parts and authorized parts for installation construction. Using parts not authorized by this company can result in water leakage, electric shock, fire and refrigerant leakage.

CAUTION

• Execute proper grounding. Do not connect the ground wire to a gas pipe, water pipe, lightning rod or a telephone ground wire. Improper placement of ground wires can result in electric shock.

• The installation of an earth leakage breaker is necessary depending on the established location of the unit. Not installing an earth leakage breaker may result in electric shock.

• Do not install the unit where there is a concern about leakage of combustible gas.
  The rare event of leaked gas collecting around the unit could result in an outbreak of fire.

• For the drain pipe, follow the installation manual to insure that it allows proper drainage and thermally insulate it to prevent condensation. Inadequate plumbing can result in water leakage and water damage to interior items.

Is The Unit Installed Correctly

Confirm the following items for safe and comfortable use of air conditioner.
The installation work is to be burden on the sales dealer, and do not conduct it by yourself.

Installation place

Avoid installing the air conditioner near the place where possibility of inflammable gas leakage exists. Explosion (Ignition) may occur.| Install the unit at well ventilated place. If some obstacle exist, it may cause capacity reduction or noise increase.| Install the air conditioner firmly on the foundation that can fully support the weight of the unit.If not, it may cause vibration or noise.
Select the place so as not to annoy neighbor with the hot air or noise.| Snow protection work is necessary where outdoor unit is blocked up by snow.
For details consult your sales dealer.| It is advisable not to install the air conditioner at the following special place.
It may cause malfunction, consult the sales dealer when you have to install the unit on such a place.
• The place where corrosive gas generates (Hot spring area etc.)
• The place where salt breeze blows (Seaside etc.)
• The place where dense soot smoke exists
• The place where humidity is extraordinarily high
• The place where near the machine which radiates the electromagnetic wave
• The place where voltage variation is considerably large

Electric work
The electric work must be burden on the authorized engineer with qualification for electric work and grounding work, and the work must be conducted in accordance with electric equipment technical standard.

• The power source for the unit is to be of exclusive use.
• An earth leakage breaker should be installed.(This is necessary to prevent electric shock.)
• The unit must be grounded.

When you change your address or the installation place
Special technology is required for removal or reinstallation of air conditioner, consult the sales dealer. Besides, construction expense is charged for removal or reinstallation.
For inspection and maintenance
The capacity of air conditioner will decrease by contamination of inside of unit when it is used for about three years although depending upon the circumstances under which it is used, and so in addition to the usual maintenance service, special inspection/maintenance service is necessary. It is recommended to make a maintenance contract (charged) by consulting your sales dealer.
