(2) High energy efficiency system

- (01 - 02) -

The configuration of 3 constant speed compressors with differing capacities and power accumulation technology ensure smooth step changes and highly efficient operation.

Flow rate between each step is controlled by power accumulation technology.

Smooth operation delivering high efficiencies

Power Accumulation Technology

Cooling and heating can be performed simultaneously within the same refrigerant circuit. Energy savings are made by transferring heat between the indoor units when in heat recovery operation.

Operating system

Flow rate to the indoor unit(s) is controlled through the use of 3 differently rated compressors operating in a sequential step arrangement.While power accumulation technology controls the circulating load of the refrigerant flow between those steps.

Outdoor unitEven if one or two compressors should fail, the remaining compressor(s) perform the recovery operation automatically while generating an alarm and, thus, the system continues to operate without any interruption.

Indoor unitEach indoor unit on the transmission line acts as an independent transmission processor, therefore, even if one unit fails, the remaining system is not affected.

Oil recovery operationOil recovery operation is performed automatically after fixed operation time to return the oil that has accumulated inside the refrigerant circuit and indoor unit.

Power distributionfacilities.

Factory automation

Officeautomation

No Harmful effects

(8) Environmentally FriendlyHarmonic-less

Our VRF system don't use inverter to control the refrigerant flow rate, thus hardly does harmonic current emit. Because the system has no harmful effects on office automation equipment, factory automation equipment and power distribution facilities, it can be used anywhere, such as in hospital where the harmonic current emissions are restricted.

Alternative refrigerantTo protect the earth's environment, alternative refrigerant R407C is used.

(9) Comfortable OperationHeat Recovery operation

Heat Recovery operation is a cooling/heating free operation system, cooling and heating can be performed simultaneously in the same refrigerant system according to user needs. At the moment, The Heat Recovery operation is an extremely superior type that provides a still greater energy saving effect by moving heat between indoor units that are performing the cooling and heating operations. This is by having the compressors act like a pump.

2-1-4 FEATURES OF CONTROL SYSTEM

1. Wiring work can be reduced since all equipment making up the system is wired withonly one transmission line (non-polar 2-conductor).

2. Since each equipment on the transmission line is independently processed, asystem failure at one indoor unit does not affect other equipment.

3.

4. Maximum 400 indoor units can be connected.

5.

6.

7.

8. By adopting an interface for FUJITSU GENERAL's single split type models (excluding somemodels) or multi air conditioner for Building models, the central control will be available from the Group remote controller or Central remote controller or PC controller.

9.

10.

Total wiring length (total length of transmission line) can be extended up to 2000m(with signal amplifier unit).

Maintenance work efficiency is improved, because PC control system can be connected to anywhere on the transmission line.

Indoor units can be controlled by Wired, Simple, Wireless, Group, Central remote controller and PC controller.

When a failure occurs, the error code is displayed and details can be confirmed atthe Wired remote controller,Simple remote controller, Group remote controller, Central remote controller, or PC controller.

Simple remote controller that allows an easy operation is available for the installationsuch as a hotel guest room.

These components can be freely combined to get the maximum control depending on the usage of the building

CAUTION

WARNINGInstall at a place that can withstand the weight of the indoor and outdoor units and install positi-vely so that the units will not topple or fall.

CAUTION

Decide the mounting position with the customer as follows:

Install the indoor unit on a strong wall which is not subject to vibration.

The inlet and outlet ports should not be obstructed :the air should be able to blow all over the room.

Do not install the unit where it will be exposed to direct sunlight.

Install the unit where the connection pipe can be easily installed.

Install the unit where the drain pipe can be easily installed.

Take servicing, etc. into consideration and leave the spaces.Also install the unit where the filter can be removed.

Do not install where there is the danger of combustible gas leakage.

Do not install the unit near a source of heat, steam, or flammable gas.

If children under 10 years old may approach the unit, take preventive measures so that they cannot reach the unit.

Use the designated size ( Diameter & thickness ) of refrigerant pipes

5-6-3. PIPING CONNECTION

CAUTION

Those pipes purchased locally may contain dust inside. Please blow out the dust by dried inert gas when using

Be careful to avoid the dust or water falling into the pipe when performing pipingprocess and piping installation.

When processing the pipe, make the number of bending portion as few as possible, and the bending radius as large as possible.

To process the branch, do not use T-shaped pipe, which causes a uneven refrigerantflow. Use the optionally available standard branch kit.

If the diameter of the required pipe is different from the branch unit, either cut it out or use the reducer.

Keep the permissible length of every piping limitation to prevent a defect or cooling/heating failure.

When replacing the unit, never use piping which has been used for previous installations. Only use the new piping.

While welding the pipes, be sure to blow dry nitrogen gas through them.

Pull the RB unit cord into the indoor unit control box and connect it to the connector (white) from the circuit board.The RB unit cord is 10 meters long. If the distance to the indoor unit exceeds the length of the RB cord, procure a cord locally and extend the length. The specifications for the cord are as follows. The length of the cord can be extended a maximum of 40 m.Specifications: 4 core shielded cord 0.75 mm or more2

CAUTIONDo not purge the air with refrigerant but use a vacuum pump to remove air from the indoor unitand connection pipes!

After the piping has been installed, perform a sealing test.Charge the piping with nitrogen to within the sealing test pressure (2.94 MPa).After 24 hours, check that the pressure has not fallen.Make sure to add the pressure to both Gas pipe and Liquid pipe.Perform the leak test on all flared and brazed parts.

AIR TIGHT TEST

VACUUM PROCESS

Remove the cap, and connect the gauge manifold and the vacuum pump to the charging valve by the service hoses.Vacuum the indoor unit and the connecting pipes until the pressure gauge indicates -76 cmHg.When -76 cmHg is reached, operate the vacuum pump for at least 1 hour.

After vacuuming inside the indoor unit and connecting pipes,remove the cap of the three valves. Open the handle (spindle) of the Large and middle valves(Ball valve).Open the spindle of the Small valve(3 way valve) with a hexagon wrench.Tighten the cap of the three valves to the specified torque.

Add refrigerant from the charging valve after the completion of the work.

The maximum length of the piping is 100 m (actual pipe length). If the units are further apart than this, correct operation can not be guaranteed.

Either larger or smaller refrigerant charge amount leads to the cause of trouble.

For after service purpose , the added refrigerant charge amount and the calculation shall be indicated firmily on the service label over the control box cover.

A. For solid core wiring (or F-cable)

Cut the wire end with a wire cutter or wire-cutting pliers, then strip the insulation to about 15/16"(25 mm) to expose the solid wire.

Using a screwdriver, remove the terminal screw(s) on the terminal board.

Using pliers, bend the solid wire to form a loop suitable for the terminal screw.

Shape the loop wire properly, place it on the terminal board and tighten securely with the terminal screw using a screwdriver.

B. For strand wiring

Cut the wire end with a wire cutter or wire-cutting pliers, then strip the insulation to about 3/8" (10 mm) to expose the strand wiring.

Using a scre wdriver, remove the terminal screw(s) on the terminal board.

Using a round terminal fastener or pliers, securely clamp a round terminal to each stripped wire end.

Position the round terminal wire, and replace and tighten the terminal screw using a screwdriver.

WARNING

Before starting work, check that power is not being supplied to the outdoor unit.

Connect the connection cord firmly to the terminal board. Imperfect installation may cause a fire.

Always fasten the outside covering of the connection cord with the cord clamp. (If the insulator is chafed,electric leakage may occur.)

Always connect the ground wire.
