WARNINGS ON REFRIGERANT LEAKAGE

Check of Concentration Limit

The room in which the air conditioner is to be installed requires a design that in the event of refrigerant gas leaking out, its concentration will not exceed a set limit.

The refrigerant R410A which is used in the air conditioner is safe, without the toxicity or combustibility of ammonia, and is not restricted by laws to be imposed which protect the ozone layer. However, since it contains more than air, it poses the risk of suffocation if its concentration should rise excessively. Suffocation from leakage of R410A is almost non-existent. With the recent increase in the number of high concentration buildings, however, the installation of multi air conditioner systems is on the increase because of the need for effective use of floor space, individual control, energy conservation by curtailing heat and carrying power etc. Most importantly, the multi air conditioner system is able to replenish a large amount of refrigerant compared with conventional individual air conditioners. If a single unit of the multi conditioner system is to be installed in a small room, select a suitable model and installation procedure so that if the refrigerant accidentally leaks out, its concentration does not reach the limit (and in the event of an emergency, measures can be made before injury can occur). In a room where the concentration may exceed the limit, create an opening with adjacent rooms, or install mechanical ventilation combined with a gas leak detection device. The concentration is as given below.

Total amount of refrigerant (kg)

Min. volume of the indoor unit installed room (m³)

≤ Concentration limit (kg/m³)

The concentration limit of R410A which is used in multi air conditioners is 0.3kg/m³.

NOTE 1 :

If there are 2 or more refrigerating systems in a single refrigerating device, the amounts of refrigerant should be as charged in each independent device.

e.g., charged amount (10kg)

Room A Room B Room C Room D Room E Room F

For the amount of charge in this example:

The possible amount of leaked refrigerant gas in rooms A, B and C is 10kg. The possible amount of leaked refrigerant gas in rooms D, E and F is 15kg.

Important

NOTE : 2

The standards for minimum room volume are as follows.

(1) No partition (shaded portion)

(2) When there is an effective opening with the

adjacent room for ventilation of leaking refrigerant gas (opening without a door, or an opening 0.15% or larger than the respective floor spaces at the top or bottom of the door).

(3) If an indoor unit is installed in each partitioned

room and the refrigerant tubing is interconnected, the smallest room of course becomes the object. But when a mechanical ventilation is installed interlocked with a gas leakage detector in the smallest room where the density limit is exceeded, the volume of the next smallest room becomes the object.

Refrigerant

Check the used refrigerant name and use tools and materials of the parts which match with it.

For the products which use R410A refrigerant, the refrigerant name is indicated at a position on the outdoor unit where is easy to see. To prevent miss-charging, the route of the service por t is changed from one of the former R22.

For an air conditioner which uses R410A, never use other refrigerant than R410A. For an air conditioner which uses other refrigerant (R22, etc.), never use R410A.

If different types of refrigerant are mixed, abnormal high pressure generates in the refrigerating cycle and an injury due to breakage may be caused.

Do not charge refrigerant additionally.

If charging refrigerant additionally when refrigerant gas leaks, the refrigerant composition in the refrigerating cycle changes resulted in change of air conditioner characteristics or refrigerant over the specified standard amount is charged and an abnormal high pressure is applied to the inside of the refrigerating cycle resulted in cause of breakage or injury. Therefore if the refrigerant gas leaks, recover the refrigerant in the air conditioner, execute vacuuming, and then newly recharge the specified amount of liquid refrigerant. In this time, never charge the refrigerant over the specified amount.

When recharging the refrigerant in the refrigerating cycle, do not mix the refrigerant or air other than R410A into the specified refrigerant.

If air or others is mixed with the refrigerant, abnormal high pressure generates in the refrigerating cycle resulted in cause of injury due to breakage.

After installation work, check the refrigerant gas does not leak.

If the refrigerant gas leaks in the room, poisonous gas generates when gas touches to fire such as fan heater, stove or cocking stove though the refrigerant gas itself is innocuous.

Never recover the refrigerant into the outdoor unit.

When the equipment is moved or repaired, be sure to recover the refrigerant with recovering device. The refrigerant cannot be recovered in the outdoor unit; otherwise a serious accident such as breakage or injury is caused.

Assembly/Cabling

After repair work, surely assemble the disassembled parts, and connect and lead the removed cables as before. Perform the work so that the cabinet or panel does not catch the inner cables.

If incorrect assembly or incorrect cable connection was done, a disaster such as a leak or fire is caused at user’s side.

WARNING

Insulator check

Ventilation

Be attentive to

electric shock

Compulsion

After the work has finished, be sure to use an insulation tester set (500V mugger) to check the resistance is 2M metal section (Earth position).

If the resistance value is low, a disaster such as a leak or electric shock is caused at user’s side.

When the refrigerant gas leaks during work, execute ventilation.

If the refrigerant gas touches to a fire, poisonous gas generates. A case of leakage of the refrigerant and the closed room full with gas is dangerous because a shortage of oxygen occurs. Be sure to execute ventilation.

When checking the circuit inevitably under condition of the power-ON, use rubber gloves and others not to touch to the charging section.

If touching to the charging section, an electric shock may be caused.

When the refrigerant gas leaks, find up the leaked position and repair it surely.

If the leaked position cannot be found up and the repair work is interrupted, pump-down and tighten the service valve, otherwise the refrigerant gas may leak into the room. The poisonous gas generates when gas touches to fire such as fan heater, stove or cocking stove though the refrigerant gas itself is innocuous.

When installing equipment which includes a large amount of charged refrigerant such as a multi air conditioner in a sub-room, it is necessary that the density does not the limit even if the refrigerant leaks.

If the refrigerant leaks and exceeds the limit density, an accident of shortage of oxygen is caused.

For the installation/moving/reinstallation work, follow to the Installation Manual.

If an incorrect installation is done, a trouble of the refrigerating cycle, water leak, electric shock or fire is caused.

After repair work has finished, check there is no trouble.

If check is not executed, a fire, electric shock or injury may be caused. For a check, turn off the power breaker.

After repair work (installation of front panel and cabinet) has finished, execute a test run to check there is no generation of smoke or abnormal sound.

If check is not executed, a fire or an electric shock is caused. Before test run, install the front panel and cabinet.

Check the following items after reinstallation.

1) The earth wire is correctly connected.

2) The power cord is not caught in the product.

3) There is no inclination or unsteadiness and the installation is stable. If check is not executed, a fire, an electric shock or an injury is caused.

air conditioner installation

(Note 1) When flaring is carried out for R410A using the conventional flare tools , adjustment of projection

margin is necessary. For this adjustment, a copper pipe gauge, etc. are necessary .

(Note 2) Charging cylinder for R410A is being currently developed.

General tools (Conventional tools can be used.)

In addition to the above exclusive tools, the following equipments which serve also for R22 are necessary as the general tools.

This air conditioner adopts a new HFC type refrigerant (R410A) which does not deplete the ozone lay er.

1. Safety Caution Concerned to New Refrigerant

The pressure of R410A is high 1.6 times of that of the former refrigerant (R22). Accompanied with change of refrigerant, the refrigerating oil has been also changed. Therefore, be sure that water, dust, the f ormer refrigerant or the former refrigerating oil is not mixed into the refrigerating cycle of the air conditioner with new refrigerant during installation work or service work. If an incorrect work or incorrect service is performed, there is a possibility to cause a serious accident. Use the tools and materials exclusiv e to R410A to purpose a safe work.

2. Cautions on Installation/Service

(1) Do not mix the other refrigerant or refrigerating oil.

For the tools exclusive to R410A, shapes of all the joints including the service port differ from those of the former refrigerant in order to prevent mixture of them.

(2) As the use pressure of the new refrigerant is high, use material thickness of the pipe and tools which are

specified for R410A.

(3) In the installation time, use clean pipe materials and work with great attention so that water and others do

not mix in because pipes are affected by impurities such as water, oxide scales, oil, etc. Use the clean pipes.

Be sure to brazing with flowing nitrogen gas. (Never use gas other than nitrogen gas.) (4) For the earth protection, use a vacuum pump for air purge. (5) R410A refrigerant is azeotropic mixture type refrigerant. Therefore use liquid type to charge the refrigerant.

(If using gas for charging, composition of the refrigerant changes and then characteristics of the air condi-

tioner change.)

3. Pipe Materials

For the refrigerant pipes, copper pipe and joints are mainly used. It is necessary to select the most appropriate pipes to conform to the standard. Use clean material in which impurities adhere inside of pipe or joint to a minimum.

(1) Copper pipe

The pipe thickness, flare finishing size, flare nut and others differ according to a refrigerant type . When using a long copper pipe for R410A, it is recommended to select “Copper or copper-base pipe without

seam” and one with bonded oil amount 40mg/10m or less. Also do not use crushed, deformed, discolored (especially inside) pipes. (Impurities cause clogging of expansion valves and capillary tubes.)

Use the flare nuts which are attached to the air conditioner unit.

(2) Joint

The flare joint and socket joint are used for joints of the copper pipe. The joints are rarely used for installa-

tion of the air conditioner. However clear impurities when using them.

5. Recharge of Refrigerant

When recharge of the refrigerant is required, charge the new refrigerant with the specified amount in the procedure as described below .

Recover the refrigerant and check there is no refrigerant in the equipment.

Connect the charge hose to the packed valve service ports at gas side, liquid side, and balance side of the outdoor unit.

Connect the charge hose to vacuum pump adaptor.

Open the packed valves of the balance pipe fully at liquid and gas sides, and then return the valve at gas side a little to the closed side.

Open fully PMV of the outdoor unit.

• Turn on power of the outdoor unit.

• Short CN30 on I/F P.C. board of the outdoor unit.

Turn off power of the outdoor unit within 2 minutes after short-circuiting.

•

Open fully the handle Low of the gauge manifold, and then turn on the power of vacuum pump for vacuuming.

When the pressure has lowered until indication of the compound gauge pointed -0.1MPa (-76cmHg), open fully the handle Low and turn off the power of vacuum pump.

Leave it as it is for 1 to 2 minutes and check the indicator of the compound gauge does not return.

Set the refrigerant cylinder on the electron balance, connect the charging hose to connecting ports of the cylinder and the electron gauge, and then charge the liquid refrigerant from the service port at liquid side. (Shield with the gauge manifold so that refrigerant does not flow to gas side.)

When the specified amount of refrigerant cannot be charged, charge the liquid refrigerant into the service port at suction gas side while carrying out the all cooling operation. In this time, reduce slightly amount of refrigerant with valve of the cylinder for charging. The liquid refrigerant may be rapidly charged, so charge the refrigerant carefully and slowly.

Never charge the refrigerant ov er the specified amount.

Do not charge the additional refrigerant.

If charging refrigerant additionally when refrigerant gas leaks, the refrigerant composition in the refrigerating cycle

changes resulted in change of air conditioner characteristics or refrigerant over the specified standard amount is

charged and an abnormal high pressure is applied to the inside of the refrigerating cycle resulted in cause of breakage

or injury.

Set the equipment so that liquid refrigerant can be charged.

When using a cylinder with siphon pipe, liquid can be charged without inversing the cylinder.

R410A refrigerant is consisted with HFC mixed refrigerant. Therefore if the refrigerant gas is charged, the composition of the charged refrigerant changes and characteristics of the equipment changes.

6. Environment

Use “Vacuum pump method” for an air purge (Discharge of air in the connecting pipe) in installation time.

• Do not discharge flon gas into the air to protect the earth environment.

• Using the vacuum pump method, clear the remained air (Nitrogen, etc.) in the unit. If the air remains , the

pressure in the refrigerating cycle becomes abnormally high and an injury and others are caused due to burst.

1. OUTLINE

“Super Heat Recovery Multi System” is a multi air conditioning system which enables each indoor unit in a refrigerant line to independently select cooling or heating operation. As it is available to operate simultaneously in cooling and heating modes, more amount of heat recovery becomes possible. This system is the most appropriate one for a building or etc. where cool and heat air are mixed such as a building of which temperature difference between each room is large due to influence of daylight or a building which has a server room requiring for cool air all day.

Heating and cooling operation are automatically selected in individual unit;

You can save time for operation.

For example, when heating is required for early morning and cooling for daytime, a Flow Selector Unit provides automatically a smooth selection of heating or cooling operation. Therefore you can obtain a comfortable room environment without feeling somewhat out of place and moreover you can save time to select heat/ cool operation.

INFORMATION

The Super Heat Recovery Multi system is different from the conventional Multi air conditioner in several points such as that heating and cooling operations are mixed or only a part of the air conditioner works cooling function. For this reason, the fo llowing table explains the operation modes of this air conditioner.
