1. INTRODUCTION

• This document is an installation manual for the Daikin Air Cooled Refrigeration Condensing Unit. Before installing the unit, read this manual thoroughly, and following the instructions contained in it. After installation, do a test run to make sure the unit runs properly, and then explain how to operate and take care of the unit to the customer, using the operation manual.

• Lastly, make sure the customer keeps this manual, along with the operation manual, in a safe place.

• This manual does not describe how to install the indoor unit. Refer to the installation manual included with the indoor unit for that.

1-1 Safety precautions

Please read these “Safety precautions” carefully before installing condensing unit and be sure to install it correctly.

Meaning of WARNING and CAUTION notices Both are important notices for safety. Be sure to follow them.

WARNING .... Failure to follow these instructions properly may

result in personal injury or loss of life.

CAUTION .....Failure to observe these instructions properly

may result in property damage or personal injury, which may be serious depending on the circum-

stances. After completing installation, conduct a test operation to confirm that the equipment operates without any problems. Then, explain to the customer how to operate the equipment and take care of it following the operation manual.

Ask the customer to store the installation manual along with the operation manual for future reference.

•

Ask your dealer or qualified personnel to carry out installation work. Do not attempt to install the condensing unit yourself. Improper installation may result in water leakage, electric shocks or fire.

• Install the condensing unit in accordance with the instructions in this installation manual. Improper installation may result in water leakage, electric shocks or fire.

• When installing the unit in a small room, take measures so that the refrigerant may not exceed the limiting concentration in the event of refrigerant leakage. Contact your dealer for further information. If the refrigerant leaks and exceeds the limiting concentration, it may lead to oxygen deficiency.

• Be sure to use only the specified accessories and parts for installation work. Failure to use the specified parts may result in the unit falling, water leakage, electric shocks or fire.

• Install the condensing unit on a foundation strong enough to withstand the weight of the unit. If a foundation does not have sufficient strength, the equipment may fall and cause injury.

• Carry out the required installation work in consideration of strong winds, typhoons or earthquakes. If the installation work is not properly carried out, the unit may fall down and cause accidents.

•

The electrical work must be carried out by the qualified electrician in accordance with the local laws and regulations and this installation manual. Make sure to provide a dedicated power supply circuit and never connect additional wiring to the existing circuit. An insufficient power supply capacity or improper electrical work may lead to electric shocks or fire.

• Be sure to earth the condensing unit. Do not earth the unit to a utility pipe, lightning conductor or telephone earth lead. Imperfect earthing may result in electric shocks or fire. A high surge current from lightning or other sources may cause damage to the condensing unit.

• Be sure to install an earth leakage breaker. Failure to install an earth leakage breaker may result in electric shocks or fire.

• Be sure to switch off the unit before touching any electrical parts. Touching a live part may result in electric shock.

• For wiring, use the specified wires and connect and fasten them firmly so that no external force from the wires may be applied to the terminal connections. If the wires are not firmly connected and fastened, it may cause heating, fire or the like.

•

When wiring the power supply and connecting transmission wiring, position the wires so that the control box lid can be securely fastened. Improper positioning of the control box lid may result in electric shocks, fire or the terminals overheating.

• If refrigerant gas leaks during installation, ventilate the area immediately. Toxic gas may be produced if the refrigerant comes into contact with fire.

• After completing installation, check for refrigerant gas leakage. Toxic gas may be produced if the refrigerant gas leaks into the room and comes into contact with a source of fire, such as a fan heater, stove or cooker.

• Do not directly touch refrigerant that has leaked from refrigerant pipes or other areas, as there is a danger of frostbite.

• Do not allow children to climb on the outside unit and avoid placing objects on the unit. Injury may result if the unit becomes loose and falls.

and insulate the pipe to prevent condensation. Improper drain piping may result in indoor water leakage and property damage.

• Install the indoor and outdoor units, power cord and connecting wires at least 1 meter away from televisions or radios to prevent picture interference and noise. (Depending on the incoming signal strength, a distance of 1 meter may not be sufficient to eliminate noise.)

• Do not install the condensing unit in the following locations:

1. Where there is a high concentration of mineral oil spray or

vapour (e.g. a kitchen). Plastic parts may deteriorate and cause parts to fall off or water to leak.

Where corrosive gas, such as sulphurous acid gas, is produced. Corrosion of copper pipes or brazed parts may occur and cause refrigerant leakage.

Where there is a machine that generates electromagnetic wave and where voltage fluctuation often occurs such as a factory. Control system may malfunction and as a result the unit may not properly operate.

4. Where flammable gas may leak, where carbon fibre or ignitable

dust is suspensions in the air, or where volatile flammables such as paint thinner or gasoline are handled. Operating the unit in such conditions may result in fire.

5. Vehicles, ships, or other places that generate vibration or cause

the condensing unit to move. The condensing unit may malfunction or cause oxygen deficiency accidents as a result of refrigerant leakage.

6. Places with excessive voltage fluctuations.

The condensing unit may malfunction.

7. Places where fallen leaves accumulate or weeds grow thick.

8. Places that become small animals’ shelter.

Small animals coming in contact with electrical parts can cause malfunctions, smoke, or ignition.

• The condensing unit is not intended for use in a potentially explosive atmosphere.

A.Clean and dry

Strict measures must be taken to keep impurities (including SUNISO oil and other mineral oils as well as moisture) out of the system.

B.Tightly sealed

Take care to keep the system tight when installing. R410A contains no chlorine, does not destroy the ozone layer and so does not reduce the earth’s protection against harmful ultraviolet radiation. R410A will contribute only slightly to the greenhouse effect if released into the atmosphere.

• Since R410A is a mixed refrigerant, the required additional refrigerant must be charged in its liquid state. If the refrigerant is charged in a state of gas, its composition changes and the system will not work properly.

• Be sure to perform refrigerant replenishment. Refer to "9. CHECKS AFTER WORK COMPLETION" on page 18 and the label of instructions on refrigerant replenishment on the cover surface of the control box,

3. SELECTION OF LOCATION

Select a location for installation that meets the following conditions. Get the customer’s permission.

1. There is no danger of fire due to leakage of inflammable gas.

2. Select the location of the unit in such a way that neither the

discharged air nor the sound generated by the unit disturb anyone.

3. The foundation is strong enough to support the weight of the unit

and the floor is flat to prevent vibration and noise generation.

4. The piping length between the outdoor unit and the indoor unit may

not exceed the allowable piping length. (Refer to "6. REFRIGERANT PIPING" on page 6)

5. Locations where the unit’s suction vent and outlet vent do not

generally face the wind. Wind blowing directly into the suction or outlet vents will interfere with the unit’s operation. If necessary, install some kind of obstruction to block the wind.

6. The space around the unit is adequate for servicing and the

minimum space for air inlet and air outlet is available. (See the "Installation Space Examples" on page 4 for the minimum space requirements.)

Examine where to install the main condensing unit and electric wires, keeping proper distances away from stereo equipment, personal computers, etc. Particularly for locations with weak reception, ensure there is a distance of at least 3 meters for indoor remote controllers, place power wiring and transmission wiring in conduits, and ground the conduits.

2. When installing in a locations where there is heavy snowfall,

implement the following snow measures.

• Ensure the base is high enough that intakes are not clogged by snow.

• Mount a snowbreak hood (optional accessory)

• Remove the rear intake grille to prevent snow from accumulating on the fins.

3. If condensate may drip on downstairs (or walkway) depending on

the floor condition, take a measure such as the installation of central drain pan kit (sold separately).

4. The refrigerant R410A itself is nontoxic, nonflammable and is safe.

If the refrigerant should leak however, its concentration may exceed the allowable limit depending on room size. Due to this it could be necessary to take measures against leakage. See “Engineering Data” for details.

5. If the outdoor units are installed in areas with heavy snowfall, the

installation of a snowbreak hood is required. This is available as an optional accessory. If the units are installed in a location where the ambient temperature can drop below –10°C, install a windbreak board or a snowbreak hood.

• When installing on a roof, make sure the roof floor is strong enough and be sure to water-proof all work.

• Make sure the area around the machine drains properly by setting up drainage grooves around the foundation. Drain water is sometimes discharged from the outdoor unit when it is running.

• If the condensing unit is of brine damage resistant or heavy brine damage resistant type, use nuts provided with resin washers to secure the product to the foundation bolts (see the illustration on the right-hand side). The rustproof effect of the nut will be lost if the coatings on the tightening portions of the nuts come off.

6. REFRIGERANT PIPING

To Piping Work Contractors

• Never open the shutoff valve until the steps specified in "7. FIELD

WIRING" on page 13 and "8-3 Checking of device and installation conditions" on page 18 of piping.

• Do not use flux at the time of brazing and connecting refrigerant pipes. Use phosphorous copper brazing filler metal (BCuP-2), which does not require flux. Chlorine-based flux causes piping corrosion. Furthermore, if fluoride is contained, the flux will have adverse influences on the refrigerant piping line, such as the deterioration of refrigerating machine oil.

• All field piping must be installed by a licensed refrigeration technician and must comply with relevant local and national regulations.

[Precautions for reuse of existing refrigerant piping/heat exchangers]

Keep the following points in mind for the reuse of existing refrigerant piping / heat exchangers. A malfunction may result if there is deficiency.

piping instead.

• The piping is different in size.

• The strength of the piping is insufficient.

• The compressor of the condensing unit previously used caused a malfunction. An adverse influence of residual substances, such as the oxidation of refrigerant oil and the generation of scale, is considered.

• If the indoor unit or outdoor unit is disconnected from the piping for a long time. The intrusion of water and dust into the piping is considered.

• The copper pipe is corroded.

• The refrigerant of the condensing unit previously used was other than R410A (e.g., R404A / R507 or R407C). The contamination of the refrigerant with heterogeneity is considered.

• If there are welded connections midway on the local piping, make

• Be sure to insulate the connection piping. The liquid and gas pipe temperatures are as follows: Liquid pipe arrival minimum temperature: 0°C Gas pipe arrival minimum temperature: –45°C In the case of thickness insufficiency, add additional insulation material or renew the existing insulation material.

• Renew the insulation material if the insulation material is degraded.

Keep the following points in mind for the reuse of existing heat exchangers

• Units with insufficient design pressure (since this product is an R410A unit) require a lower-stage design pressure of 2.5 MPa [25 bars].

• Units for which the path to the heat exchanger has been routed so that the flow of refrigerant is from bottom to top

• Units with copper tubing or fan corrosion

• Units that may be contaminated with foreign matter such as rubbish or other dirt

gas leakage checks on the welded connections.

6-1 Selection of piping material

•

Make sure that the inner side and outer side of the piping used is clean and free of contaminants, such as sulphur, oxide, dust, chips, oil and fat, and water. It is desirable that the maximum oil adhesion in the piping is 30 mg per 10 m.

• Use the following type of refrigerant piping. Material: Seamless phosphorus deoxidized copper tube (C1220T-O for a maximum outer diameter of 15.9 mm and C1220T-1/2H for a minimum

Refrigerant piping size and wall thickness: Decide the size and thickness from the following table.

(This product uses R410A. The withstand pressure of O type may be insufficient if it is used for piping with a minimum diameter of

19.1 mm. Therefore, be sure to use 1/2 H type with a minimum thickness of 1.0 mm. If O type is used for piping with a minimum diameter of 19.1 mm, a minimum thickness of 1.2 mm will be required. In that case, be sure to perform the blazing of each joint.)

• Be sure to perform piping work within the range specified in the following tables.

6-3 Pipe connection

•

Be sure to perform nitrogen permutation or nitrogen blow when brazing.

6-4 Connecting the refrigerant piping

• In addition to gas and liquid shutoff valves, this unit has a maintenance shutoff valve (see diagram below).

• Do not operate the maintenance shutoff valve*. (The factory setting for the maintenance shutoff valve is “open.” During operation, always leave this valve in the open position. Operating the unit with the valve in the closed position may cause the compressor to fail.)

Brazing without performing nitrogen permutation or nitrogen blow into the piping will create large quantities of oxidized film on the inside of the pipes, adversely affecting valves and compressors in the refrigerating system and preventing normal operation.

• The pressure regulator for the nitrogen released when doing the brazing should be set to 0.02 MPa (about 0.2 kg/cm feel a slight breeze on your cheek).

Do not use anti-oxidants when brazing the pipe joints. Residue can clog pipes and break equipment.

Operation Method of Shutoff Valves

Follow the instructions below when operating each shutoff valve.

• Do not open the shutoff valve until the steps specified in “8-3 Checking of device and installation conditions” is completed. Do not leave the shutoff valve opened without turning the power on, otherwise refrigerant may be condensed in the compressor and the insulation of the main power supply circuit may be degraded.

• Be sure to use an exclusive tool to handle the shutoff valve. The shutoff valve is not of back sheet type. Excessive force imposed may break the valve.

• Use a charge hose when using the service port.

• Make sure that there is no refrigerant gas leakage after the valve cover and cap are securely tightened.

Precautions for Piping

Perform piping branching with the following conditions kept in mind.

• At the time of branching the liquid piping, use a T-joint or Y-joint and branch it horizontally. This will prevent an uneven flow of refrigerant.

• At the time of branching gas piping, use a T-joint and branch it so that the branched piping will be located above the main piping (see the illustration below). This will prevent the stay of refrigerant oil in the indoor unit not in operation.

• Use a Y-joint for the liquid refrigerant branch and have the piping branch horizontally.

7. FIELD WIRING

To electric engineering contractors

• Be sure to install an earth leakage breaker. The product incorporates inverter equipment. In order to prevent the malfunctioning of the earth leakage breaker, make sure that the earth leakage breaker withstands harmonic interference.

• Do not operate the condensing unit until refrigerant piping work is completed, or otherwise the compressor will malfunction.

• Do not remove any electrical components such as thermistors or sensors when connecting power supply wires or transmission wires. The compressor may malfunction if the condensing unit is operated with such electrical components removed.

• Be sure to install an earth leakage circuit breaker. This unit uses an inverter, so install the earth leakage circuit breaker that be capable of handling high harmonics in order to prevent malfunctioning of the earth leakage circuit breaker itself.

• Earth leakage circuit breaker which are especially for protecting ground-faults should be used in conjunction with main switch or fuse for use with wiring.

• Electrical wiring must be done in accordance with the wiring diagrams and the description herein.

• Do not operate until refrigerant piping work is completed. (If operated before complete the piping work, the compressor may be broken down.)

• Never remove thermistor, sensor or etc. when connecting power wiring and transmission wiring. (If operated with thermistor, sensor or etc. removed, the compressor may be broken down.)

• This product have reversed phase protection detector that only works when the power is turned on. If there exists black out or the power goes on and off which the product is operating, attach a reversed phase protection circuit. Running the product in reversed phase may break the compressor and other parts.

• Attach the power wire securely. Introducing power with a missing N-phase or with a mistaken N-phase will break the unit.

• Never connect the power supply in reversed phase. The unit can not operate normally in reversed phase. If you connect in reversed phase, replace two of the three phases.

• Make sure the electrical unbalance ratio is no greater than 2%. If it is larger than this, the unit’s lifespan will be reduced. If the ratio exceeds 4%, the unit will shut down and an malfunction code will be displayed on the indoor remote controller.

• Connect the wire securely using designated wire and fix it with attached clamp without applying external pressure on the terminal parts (terminal for power wiring, terminal for transmission wiring and earth terminal).

• Install a switch that allows you to switch OFF all poles from the main power supply.

• The total maximum refrigerant charge of a Multi-ZEAS system must be less than 100 kg, this to be in accordance with CE requirements (EN603350-2-40 standard). This means that in case the calculated total refrigerant charge is equal to or more than 95 kg you must divide your multiple outdoor system into smaller independent systems, each containing less than 95 kg refrigerant charge.

• Refer to the "Operation Method of Shutoff Valves" on page 9 for the control method of the shutoff valves.

• Never replenish liquid refrigerant directly from a gas line. Liquid compression and overheating may cause the compressor to fail.

The refrigerant must be noted for this product. Calculate the amount

1. of refrigerant replenishment according to the label for the calculation of the amount of refrigerant replenishment.

2. Take the following procedure for refrigerant replenishment. Refer to "8-1 Airtight test/refrigerant oil charging/vacuum drying"

on page 16 for the connection of the refrigerant cylinder.

3. Turn on the indoor unit and control panel. Do not turn on the outdoor unit.

4. Replenish refrigerant from the service port of the shutoff valve on the liquid side.

5. If the refrigerant is charged while the compressor is running, set the target evaporating temperature to ≥–25°C. Make sure the master unit is properly designated. Refer to "11. FIELD

SETTINGS" on page 20.

6. If the calculated amount of refrigerant cannot be filled, take the following steps to operate the system and continue refrigerant replenishment. a. Open the gas shutoff valve all the way and adjust the opening of

the liquid shutoff valve (*1).

b.[Warning/electric shock warning]

Turn on the outdoor unit.

c.[Warning/electric shock warning]

Turn on the operation switch of the outdoor unit and replenish refrigerant while the outdoor unit is in operation.

d.Turn off the operation switch of the outdoor unit after the speci-

fied amount of refrigerant is replenished. (To prevent liquid compression)

e.[Caution]

Fully open the shutoff valves on the gas and liquid sides promptly. Otherwise, a piping explosion may result from liquid sealing. Label pasting position:

*1The cylinder’s internal pressure will drop when there is little

refrigerant remaining in the cylinder, making it impossible to charge the unit, even if the liquid shutoff valve opening is adjusted. In this situation, replace the cylinder with one that has more refrigerant remaining. Additionally, if the piping length is long, replenishing while the liquid shutoff valve is fully closed may lead to activation of the protection system, causing the unit to stop operation.

7. After the work is completed, apply a screw lock agent (for flare nuts) to the screws of the shutoff valves and service ports. Refer to the "Handling precautions for valve cover" on page 10 and

"Handling Precautions for Service Port" on page 10 in "64 Connecting the refrigerant piping" on page 8 for the handling of

the valve covers and service ports.

8. After the refrigerant replenishment is completed, fill out the item “total amount of refrigerant replenishment” on the label of instructions on refrigerant replenishment of the outdoor unit with the actual amount of refrigerant replenishment. Refer to the illustration of the label pasting position for instructions on refrigerant replenishment (see the illustration on the above).

Making field settings

Settings are made on the master unit only. Do not make settings on the slave unit. Designate the outdoor unit closest to the branch section as master unit. To make field settings:

1. Turn off the operation switch of the master unit

2. Turn off the power supply of the master and the slave unit.

3. Set the target evaporating temperature with DS1.

Target evaporating temperature (TEM)

• Fully open the shutoff valves on the liquid and gas sides after the refrigerant replenishment is finished. The compressor will malfunction if the system is operated with the shutoff valves closed.

• Apply a screw lock agent to the screws of the valve cover

mounting parts and service ports.

(Otherwise, dew condensation water will intrude and freeze inside and cause cap deformation or damage, which may result in refrigerant gas leakage or compressor malfunctions.)

11. FIELD SETTINGS

• Securely close the control box lid before turning power on.

• Before turning power on, check through the inspection hole (on the left-hand side) of the control box lid that the operation switch is set to OFF. If the operation switch is set to ON, the fan may rotate.

• Check the LED indicators on the PCB (A1P) of the outdoor unit through the inspection hole (on the right-hand side) of the control box lid after the outdoor unit is turned on (see the illustration). (The compressor will not operate for approximately 2 minutes after the outdoor unit is turned on. H2P blinks for the first five seconds when the power supply is turned on. If the equipment is normal, H2P will be turned off in five seconds. H2P lights for abnormality.)

Operating the push-button and DIP switches

Turn on the unit and open the inspection door as illustrated by the figure above. Operate the switches by using a resin ballpoint or another non-conducting object. Close the inspection door after the work is finished.

4. Designate the master unit with DS2.

Setting of master unit

5. Turn on the power supply of the master and the slave unit.

6. Check that LED H4P is lit. If so, the master unit has successfully

been designated.

7. Check that LED H5P is lit. If so, the multi-system has correctly

been set. LED H5P lights up five seconds after turning on the power and stays lit.

For test run operators

Do not operate the outdoor unit alone on a trial basis. In a multi-system, all units work together. It is not possible to operate the master or a slave unit seperately.

Test run procedure

Use the following procedure to perform a test run after installation work is complete for the entire system:

1. Fully open the shutoff valves on the gas and liquid sides of both

master and slave unit.

2. Set the operation switch of the master unit to ON.

Note: Before turning power on, check that the piping cover and

control box lid of the outdoor unit are closed.

3. Check the sealing condition of the outdoor unit through the sight

glass. Make sure that the amount of refrigerant is sufficient.

4. Make sure that cold air blows from the indoor unit.

Check that the internal temperature is dropping. (Check that the temperature will drop and reach the set temperature in the internal unit. Check that the indoor unit (for refrigeration or freezing) goes into defrosting operation.

Turn power off with the operation switch of the outdoor unit set to OFF. (Stopping unit operation by disconnecting the power supply directly is dangerous. When the unit is stopped in this manner, its power outage compensation function may cause it to resume operation as soon as the power supply is reactivated. Additionally, stopping the unit in this manner may cause the compressor to fail).

Error diagnosis

• If the system cannot operate normal at the time of test run (i.e., the H2P indicator is lit), check with malfunction code on the system with the pushbutton switches on the PCB of the outdoor unit, and take the following steps.

• Check the LED display of the master unit for both master and slave unit errors.

If an error occurs, the LEDs of the master unit display can light up in the following ways:

LED (H2P): ON LED (H7P): ON

LED (H2P) LED (H7P)

Take action according to the status of LED(H7P):

• If H7P is lit, check the malfunction code on the PCB of the master unit.

• If H7P is not lit, check the malfunction code on the PCB of the slave unit.

• If H7P is blinking, check the malfunction codes on both the PCB of the master unit and that of the slave unit.

• To check the malfunction code on one of the PCB’s, refer to

"How to check malfunction code" on page 21.

• If one of the units stops functioning due to a compressor malfunction, the non-malfunctioning unit will also stop.

How to check malfunction code

By operating the pushbutton switches on the PCB, malfunction code items can be displayed on the condensing unit.

1. Make sure that the LED “H1P” is off. (If the LED is on, press the MODE button (BS1) once.)

2. Press the MODE button (BS1) once. The LED (H1P) starts blinking.

3. Press the RETURN button (BS3) to display the first digit of the malfunction code on the LED.

4. Press the SET button (BS2) to display the second digit of the malfunction code on the LED.

LED (H2P): ON LED (H7P): OFF LED (H2P): ON LED (H7P): blinking

Master unit malfunction

Slave unit malfunction

RETURN

TEST

RESET

*1 Set the operation switch of the master unit to the OFF position to reset the power supply and then return the operation switch of the master unit to the ON position to restart the unit. If the problem persists, refer to the Service Manual. *2 If a transmission error occurs for 2 continuous minutes, the system will stop. The corresponding malfunction code is displayed 10 minutes after the onset of the error.

• Do not disconnect the power supply for 1 minute after setting the operation switch to ON. Electric leak detection is performed for several seconds after the operation switch is set to ON and each compressor starts operating, so disconnecting the power supply during that time will result in a false detection.

For dealers

• After the test run is finished, check that the piping cover and front panel are mounted.

• At the time of delivery to the customer, use the operation manual and fully explain the handling of the equipment.

• For precautions at the time of delivery, refer to the provided installation manual for each unit as well.
