WARNING

CAUTION

WARNING

CAUTION

This system should be applied to places of office, restaurant, residence and the like. Appliaction 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 purchased 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 installment 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.

WARNING

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.

Please read these "Safety Precautions" first then accurately execute the installation work. Though the precautionary points indicated herein are divided under two headings, and 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 section. However, there is also a possibility of serious consequences in relationship to the points listed in the section as well.

SAFETY PRECAUTIONS

3 SAFETY PRECAUTIONS

When setting up or moving the location of the air conditioner, do not mix air etc. or anything other than the designated refrigerant (please see nameplate) 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 refigerant leakage. The position of indoor unit must be above the floor 2.5m.

WARNING

Execute proper grounding. Do not connect the ground wire to a gas pipe, water pipe, lightening 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.

(4) Cutoff protection against overload and overheat

During heating program, if the indoor blowing fan has been started and the compressor

has been running more than 2 minutes, and the temperature of indoor coil pipe (Ticp)

> 64

, the outdoor blowing fan will stops running; If Ticp ≤ 50 and the outdoor

blowing fan has kept stop state for 45 seconds, then it will restore rotation; If Ticp > 67

and such temperature has last for 10 seconds, the compressor will stop running and

indoor blowing fan run according to conditions as it reaches setting temperature. When

Ticp < 58

, and the compressor has kept stop state over 3 minutes, then the

compressor and outdoor blowing fan will restore normal running.

Cutoff protection for heating current

After 60 seconds from the compressor being started, if CT current exceeds I1 (9.2A) and

such case has kept 5 seconds, the outdoor blowing fan will stop. If 45 seconds has passed

after the outdoor blowing stops and the current of the compressor is less than I2 (7.5A), the

blowing fan will restore running. If CT current exceeds I3 (14.3A) and such case lasts for 3

seconds, the compressor and outdoor blowing fan will stop. The compressor will not restore

running until 3 minutes passes with CT current less than 12A.

(5) Cool wind prevention during heating program

At the first time entering heating program or after ending the latest frost removal, if the

temperature of indoor coil pipe (Ticp) < 28

, the indoor blowing fan will stop running; If

compressor has been running for more than 4 minutes, the indoor blowing fan will run at

ELECTRICAL CONTROL FUNCTIONS

setting wind speed.

(6) Afterheat blowing during heating program

During heating program, the compressor will stop running (except overheat protection or

frost removal) while the indoor blowing fan will firstly run for 50 seconds at low speed then

stop.

(7) Frost removal control (applicable for cooling-heating type)

Starting conditions for frost removal:

A The indoor unit is in overload protection and outdoor blowing fan stops. The outdoor

blowing fan does not enter overheat mode in 10 minutes after it is restarted, the

compressor has run over 45 minutes totally while 20 minutes continuously, and the

temperature of indoor coil pipe is lower than 43 ;

B After the compressor continuously running for 20 minutes, the temperature of indoor

coil pipe falls 1 every 6 minutes and such case continuously appears three times,

and the temperature of indoor coil pipe is less than 40 , and 5 minutes have passed

after the compressor is restarted;

C The compressor has run totally over 3 hours while 20 minutes continuously, and the

temperature of indoor coil pipe is less than 40 ;

D The difference between room temperature and the one of indoor coil pipe is less than

16 and the compressor has totally run over 45 minutes while 20 minutes

continuously;

Frost removal will start if any one of the above conditions is satisfied.

Ending conditions for frost removal:

1 Time of frost removal has exceeded 9 minutes; 2 CT current exceeds I4(8.2A)

Actions of each load after the frost removal starts:

The compressor and outdoor blowing fan stop, and indoor blowing fan also stops.

55 seconds later the reversal valve is closed and next 5 seconds later the compressor is

started.

Actions of each load after the frost removal ends:

The compressor stops running while outdoor blowing fan immediately runs at high

speed, 55 seconds later the reversal valve is opened and next 5 seconds later the

compressor restores running and indoor blowing fan runs as conditions for cool wind

prevention.

(8) Freeze protection

After the compressor has run for 9 minutes, the system will check temperature of

indoor coil pipe (Ticp). If Ticp is less than -1

, the compressor and outdoor blowing

fan will stop. They will run again after the compressor stops if both the following

conditions are satisfied:

1) 3 minutes have passed since compressor stops.

2) Ticp exceeds 7

.

(9) 3 minutes protection for compressor

After compressor stops, it cannot be started until 3 minutes later. During the machine’s

running, if time after loosing power not exceeds 3 minutes, the compressor cannot be

ELECTRICAL CONTROL FUNCTIONS

restarted until 3 minutes later after it is reenergized.

10 Power breakdown memory

stops.

b. When water tank is fully filled, the float switch will be off. The water pump will start

to work after a controller has detected this signal and it will continue working for 5

minutes after the float restores to normal state.

c. If the full water signal is detected continuously over 5 minutes, the water pump

indicator lamp will flash to alarm and compressor stops running. The water pump

will run 5 minutes, then pause for 5 seconds before next 5 minutes’ running, ... until

the float restores to normal state, after which the pump will run for 5 minutes then

stop.

ELECTRICAL CONTROL FUNCTIONS

9.2 Introduction to the fan speed controller

210V

60V

27 35 39 42

The low ambient temperature cooling system realizes starting normally at the

temperature -15

by the method of: The sensor collects the coil temperature to change

the voltage of the outdoor fan motor, thus to change the fan speed. As a result, the system

pressure is restricted.

1.When the coil temperature exceeds 42

,the voltage would be the highest value

210V and the fan motor runs in the normal way. As the outdoor temperature descends, the

condensator temperature descends too, and the pressure of the compressor discharge

lowers. The voltage of the fan motor falls along with the coil temperature. According to the

above chart (the coil temperature descends, the fan speed descends too), when the

temperature falls to 39

, the fan motor runs in the lowest voltage 60V, and if the

temperature falls continuously to 27

, the outdoor fan motor stops.

2.When the fan motor stops, the pressure of the compressor discharge rises

gradually, and also the condensator temperature. If the temperature rises to 35

, the

outdoor fan motor starts and runs in the lowest voltage 60V. If the condensator

temperature can not stop rising, when it is 39

, the fan speed will rise according to the

line in the above chart until the temperature be 42

, and then the fan motor will run in the

normal way.
