DAIKIN AIR CONDITIONER

INSTALLATION MANUAL1-6

When wiring the power supply and connecting the wiring between the indoor and outdoor units, 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 overheating terminals.

After connecting interconnecting and supply wiring, be sure to shape the cables so that they do not put undue force on the electrical covers or panels. Install covers over the wires. Incomplete cover installation may cause terminal overheating, electrical shocks, or ﬁre.

When installing or relocating the air conditioner, be sure to bleed the refrigerant circuit to ensure it is free of air, and use only the speciﬁed refrigerant (R32). The presence of air or other foreign matter in the refrigerant circuit cause abnormal pressure rise, which may result in equipment damage and even injury.

The installation height from the ﬂoor must be over 2.7m.

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.

During pump-down, stop the compressor before removing the refrigerant piping. If the compressor is still running and the stop valve is open during pump-down, air will be sucked in when the refrigerant piping is removed, causing abnormal pressure in the refrigeration cycle, which may result in equipment damage and even injury.

During installation, attach the refrigerant piping securely before running the compressor. If the refrigerant pipes are not attached and the stop valve is open when the compressor is run, air will be sucked in, causing abnormal pressure in the refrigeration cycle, which may result in equipment damage and even injury.

Be sure to earth the air conditioner. Do not earth the unit to a utility pipe, lightning conductor or telephone earth lead. Imperfect earthing may result in electric shocks.

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

All electrical wiring must not touch the water piping or any moving parts of the fan motors.

Conﬁrm that the unit has been switched OFF before installing or servicing the unit.

Disconnect from the main power supply before servicing the air conditioner unit.

DO NOT pull out the power cord when the power is ON. This may cause serious electrical shocks which may result in ﬁre hazards.

Keep the indoor and outdoor units, power cable and transmission wiring, at least 1m from TVs and radios, to prevent distorted pictures and static. Depending on the type and source of the electrical waves, static may be heard even when more than 1m away.

Do not use means to accelerate the defrosting process (if applicable) or to clean, other than those recommended by the manufacturer.

The appliance must be stored in a room without continuously operating ignition sources (for example: open ﬂames, an operating gas appliance or an operating electric heater).

Do not pierce or burn.

Be aware that refrigerants may not contain an odour.

The appliance must be installed, operated and stored in a room with a ﬂoor area larger than Xm2 (refer to Section “Special Precautions When Dealing With R32 Unit”). In case it does not satisfy minimum ﬂoor area, it requires to install at good ventilation room.

NOTE: The manufacturer may provide other suitable examples or may provide additional information about the refrigerant odour.1-7 English CAUTION

Do not install the air conditioner at any place where there is danger of ﬂammable gas leakage. In the event of a gas leakage, build-up of gas near the air conditioner may cause a ﬁre to break out.

While following the instructions in this installation manual, install drain piping to ensure proper drainage and insulate piping to prevent condensation. Improper drain piping may result in indoor water leakage and property damage.
Tighten the ﬂare nut according to speciﬁed method such as with a torque wrench. If the ﬂare nut is too tight, it may crack after prolonged use, causing refrigerant leakage.
Do not overcharge the unit. This unit is factory pre-charged. Overcharge will cause over-current or damage to the compressor.
Ensure that the unit’s panel is closed after service or installation. Unsecured panels will cause the unit to operate noisily.
Sharp edges and coil surfaces are potential locations which may cause injury hazards. Avoid from being in contact with these places.
Before turning off the power supply set the remote controller’s ON/OFF switch to the “OFF” position to prevent the nuisance tripping of the unit. If this is not done, the unit’s fans will start turning automatically when power resumes, posing a hazard to service personnel or the user.

Make sure to provide for adequate measure in order prevent that the outdoor unit be used as a shelter by small animals. Small animal making contact with electrical parts can cause malfunctions, smoke or ﬁre. Please instruct the customer to keep the area around the unit clean.
The temperature of refrigerant circuit will be high, please keep the inter-unit wiring away from copper pipes that are not thermally insulated.

Only qualiﬁed personnel can handle, ﬁll, purge and dispose of the refrigerant. NOTICE Disposal requirements Your air conditioning product is marked with this symbol. This means that electrical and electronic products shall not be mixed with unsorted household waste.

When piping work is completed, it is necessary to purge the air and check for gas leakage

1) Do not mix any substance other than the speciﬁed refrigerant (R32) into the refrigeration cycle.

2) When refrigerant gas leaks occur, ventilate the room as soon and as much as possible.3) R32, as well as other refrigerants, should always be recovered and never be released directly into the environment. 4) Use a vacuum pump for R32 exclusively. Using the same vacuum pump for different refrigerants may damage the vacuum pump or the unit. WARNING

If using additional refrigerant, perform air purging from the refrigerant pipes and indoor unit using a vacuum pump, then charge additional refrigerant.

Use a hexagonal wrench (4mm) to operate the stop valve rod.

All refrigerant pipe joints should be tightened with a torque wrench at the speciﬁed tightening torque. Pressure meterValve caps Liquid stop valveGas stop valveVacuum pump Service portHigh pressure valveLow-pressure valveCharging hosesCompound pressure gaugeGauge manifold

4) After two to three minutes, close the gas stop valve and stop forced cooling

Do not use tapped wires, extension cords, or starburst connections, as they may cause overheating, electric shock, or ﬁre.• Do not use locally purchased electrical parts inside the product. (Do not branch the power for the drain pump, etc., from the terminal block.) Doing so may cause electric shock or ﬁre.• Be sure to install a earth leakage circuit breaker. (One that can handle higher harmonics.)(This unit uses an inverter. Therefore, a earth leakage circuit breaker capable of handling higher harmonics must be used in order to prevent the earth leakage circuit breaker malfunctioning.)• Use an all-pole disconnection type circuit breaker with at least 3mm (1/8 inch) between the contact point gaps.• When carrying out wiring, take care not to pull at the conduit.• Do not connect the power wire to the indoor unit. Doing so may cause electric shock or ﬁre.• Do not turn on the circuit breaker until all work is completed.1) Strip the insulation from the wire (20mm).2) Connect the inter-unit wires between the indoor and outdoor units so that the terminal numbers match. Tighten the terminal screws securely. It is recommended that a ﬂathead screwdriver be used to tighten the screws. The screws are packed with the terminal block.

Forced cooling operation will stop automatically after around 15 minutes. To stop the operation, press the indoor unit ON/OFF switch. After closing the liquid stop valve, close the gas stop valve within 3 minutes, then stop the forced cooling operation.

Pump down - Refrigerant leakage. If you want to pump down the system, and there is a leakage in the refrigerant circuit:

Do NOT use the unit's automatic pump down function, with which you can collect all refrigerant from the system into the outdoor unit. Possible consequence: Self-combustion and explosion of the compressor because of air going into the operating compressor.

Use a separate recovery system so that the unit's compressor does NOT have to operate. NOTICE During pump down operation, stop the compressor before removing the refrigerant piping. If the compressor is still running and the stop valve is open during pump down, air will be sucked into the system. Compressor breakdown or damage to the system can result due to abnormal pressure in the refrigerant cycle.1-21 English SPECIAL PRECAUTIONS WHEN DEALING WITH R32 UNIT ModelR32 charge, kgfor 7.5m pipingMinimum ﬂoor area,

WARNING Prior to installation, ensure risk of ignition is minimised and avoid working in conﬁned space. Ensure adequate ventilation is available by opening windows or doors. ● When ﬂared joints are reused indoors, the ﬂare part shall be re-fabricated. ● A void installation of the air conditioner in a place where there is danger of exposure to continuously operating open ﬂames (for example an operating electric heaters). ● Any person who is involved with working on or breaking into a refrigerant circuit should hold a current valid certiﬁcate from an industry-accredited assessment authority, which authorises their competence to handle refrigerants safely in accordance with an industry recognised assessment speciﬁcation. ● Checking for presence of refrigerant The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is aware of potentially ﬂammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with ﬂammable refrigerants, i.e. nonsparking, adequately sealed or intrinsically safe. ● Presence of ﬁre extinguisher If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate ﬁre extinguishing equipment shall be available to hand. Have a dry powder or CO

ﬁre extinguisher adjacent to the charging area. ● No ignition sources All possible ignition sources, including cigarette smoking, should be kept sufﬁciently far away from the site of installation, repairing, removing and disposal, during which ﬂammable refrigerant can possibly be released to the surrounding space. “No Smoking” signs shall be displayed. ● The following checks shall be applied to installations: – marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be corrected; – refrigeration pipe or components are installed in a position where they are unlikely to be exposed to any substance which may corrode refrigerant containing components, unless the components are constructed of materials which are inherently resistant to being corroded or are suitably protected against being so corroded. ● Initial safety checks shall include: – that capacitors are discharged, this shall be done in a safe manner to avoid possibility of sparking – there shall be no live electrical components and wiring are exposed while charging, recovering or purging the system;1-22 ● Repair to intrinsically safe components Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the permissible voltage and current permitted for the equipment in use. Replace components only with parts speciﬁed by the manufacturer. ● Leak detection methods Ensure that the detector is not a potential source of ignition (for example a halide torch) and is suitable for the refrigerant used. Leak detection equipment shall be set at a percentage of the LFL of the refrigerant (for R32, LFL is 13%) and shall be calibrated to the refrigerant employed and the appropriate percentage of gas (25% maximum) is conﬁrmed. Leak detection ﬂuids are suitable for use with most refrigerants but the use of detergents containing chlorine shall be avoided as the chlorine may react with the refrigerant and corrode the copper pipework. If a leak is suspected, all naked ﬂames shall be removed/extinguished. If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall be recovered from the system, or isolated (by means of shut off valves) in a part of the system remote from the leak. Oxygen free nitrogen (OFN) shall then be purged through the system both before and during the brazing process. ● Removal and evacuation When breaking into the refrigerant circuit to make repairs – or for any other purpose – conventional procedures shall be used. However, it is important that best practice is followed since ﬂammability is a consideration. The following procedure shall be adhered to: ● remove refrigerant; ● purge the circuit with inert gas; ● evacuate; ● purge again with inert gas; ● open the circuit by cutting or brazing. The refrigerant charge shall be recovered into the correct recovery cylinders. The system shall be “ﬂushed” with OFN to render the unit safe. This process may need to be repeated several times. Compressed air or oxygen shall not be used for this task. Flushing shall be achieved by breaking the vacuum in the system with OFN and continuing to ﬁll until the working pressure is achieved, then venting to atmosphere, and ﬁnally pulling down to a vacuum. This process shall be repeated until no refrigerant is within the system. When the ﬁnal OFN charge is used, the system shall be vented down to atmospheric pressure to enable work to take place. This operation is absolutely vital if brazing operations on the pipe- work are to take place. Ensure that the outlet for the vacuum pump is not close to any ignition sources and there is ventilation available. ● Labelling This unit shall be labelled ‘de-commissioned and emptied of refrigerant’. This label shall be dated and signed. Ensure that there are labels on the equipment stating the equipment contains ﬂammable refrigerant. ● Charging procedures In addition to conventional charging procedures, the following requirements shall be followed. – Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines shall be as short as possible to minimise the amount of refrigerant contained in them. – Cylinders shall be kept upright. – Ensure that the refrigeration system is earthed prior to charging the system with refrigerant. – Label the system when charging is complete (if not already). – Extreme care shall be taken not to overﬁll the refrigeration system. Prior to recharging the system it shall be pressure tested with OFN. The system shall be leak tested on completion of charging but prior to commissioning. A follow up leak test shall be carried out prior to leaving the site.1-23 English Decommissioning Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its detail. It is recommended good practice that all refrigerants are recovered safely. Prior to the task being carried out, an oil and refrigerant sample shall be taken in case analysis is required prior to re-use of reclaimed refrigerant. It is essential that electrical power is available before the task is commenced. a) Become familiar with the equipment and its operation. b) Isolate system electrically. c) Before attempting the procedure ensure that:

mechanical handling equipment is available, if required, for handling refrigerant cylinders;

all personal protective equipment is available and being used correctly;

the recovery process is supervised at all times by a competent person;

recovery equipment and cylinders conform to the appropriate standards. d) Pump down refrigerant system, if possible. e) If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system. f) Make sure that cylinder is situated on the scales before recovery takes place. g) Start the recovery machine and operate in accordance with manufacturer’s instructions. h) Do not overﬁll cylinders. (No more than 80 % volume liquid charge).

i) Do not exceed the maximum working pressure of the cylinder, even temporarily.

j) When the cylinders have been ﬁlled correctly and the process completed, make sure that the cylinders and the equipment are removed from site promptly and all isolation valves on the equipment are closed off. k) Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and checked. Recovery When removing refrigerant from a system, either for servicing or decommissioning, it is recommended good practice that all refrigerants are removed safely. When transferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are employed. Ensure that the correct number of cylinders for holding the total system charge are available. All cylinders to be used are designated for the recovered refrigerant and labelled for that refrigerant (i.e. special cylinders for the recovery of refrigerant). Cylinders shall be complete with pressure relief valve and associated shut-off valves in good working order. Empty recovery cylinders are evacuated and, if possible, cooled before recovery occurs. The recovery equipment shall be in good working order with a set of instructions concerning the equipment that is at hand and shall be suitable for the recovery of ﬂammable refrigerants. In addition, a set of calibrated weighing scales shall be available and in good working order. Hoses shall be complete with leak-free disconnect couplings and in good condition. Before using the recovery machine, check that it is in satisfactory working order, has been properly maintained and that any associated electrical components are sealed to prevent ignition in the event of a refrigerant release. Consult manufacturer if in doubt. The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylinder, and the relevant Waste Transfer Note arranged. Do not mix refrigerants in recovery units and especially not in cylinders. If compressors or compressor oils are to be removed, ensure that they have been evacuated to an acceptable level to make certain that ﬂammable refrigerant does not remain within the lubricant. The evacuation process shall be carried out prior to returning the compressor to the suppliers. Only electric heating to the compressor body shall be employed to accelerate this process. When oil is drained from a system, it shall be carried out safely.1-24 COMMISSIONING
