WARNING

This appliance is fi lled with R32 (mild fl ammable refrigerant).

If the refrigerant is leaked and exposed to an external ignition source, there is a risk of fire.

Indoor unit and outdoor unit

The appliance shall be installed, and/or operated in a room with floor area larger than A_min ( m^2 ) and keep away from ignition sources, such as heat/sparks/open flame or hazardous areas such as gas appliances, gas cooking, reticulated gas supply systems or electric cooking appliances, etc. (Refer to Installation instructions table for A_min ( m^2 ))

Be aware that refrigerant may not contain an odour, highly recommended to ensure suitable fl ammable refrigerant gas detectors are present, operating and able to warn of a leak.

Keep any required ventilation openings clear of obstruction.

Do not pierce or burn as the appliance is pressurized. Do not expose the appliance to heat, flame, sparks, or other sources of ignition. Else it may explode and cause injury or death.

Precaution for using R32 refrigerant

The basic installation work procedures are the same as conventional refrigerant (R410A, R22) models.

Since the working pressure is higher than that of refrigerant R22 models, some of the piping and installation and service tools are special. Especially, when replacing a refrigerant R22 model with a new refrigerant R32 model, always replace the conventional piping and fl are nuts with the R32 and R410A piping and fl are nuts on the outdoor unit side. For R32 and R410A, the same fl are nut on the outdoor unit side and pipe can be used.

The mixing of different refrigerants within a system is prohibited. Models that use refrigerant R32 and R410A have a different charging port thread diameter to prevent erroneous charging with refrigerant R22 and for safety.

Therefore, check beforehand. [The charging port thread diameter for R32 and R410A is 1/2 inch.]

Must always ensure that foreign matter (oil, water, etc.) does not enter the piping. Also, when storing the piping, securely seal the opening by pinching, taping, etc. (Handling of R32 is similar to R410A.)

- Operation, maintenance, repairing and refrigerant recovery should be carried out by trained and certified personnel in the use of flammable refrigerants and as recommended by the manufacturer. Any personnel conducting an operation, servicing or maintenance on a system or associated parts of the equipment should be trained and certified.

• The check shall also take into account the effects of aging or continual vibration from sources such as compressors or fans.

6. Detection of fl ammable refrigerants

• Under no circumstances shall potential sources of ignition be used in the searching or detection of refrigerant leaks.
• A halide torch (or any other detector using a naked fl ame) shall not be used.

7. The following leak detection methods are deemed acceptable for all refrigerant systems

• No leaks shall be detected when using detection equipment with a sensitivity of 5 grams per year of refrigerant or better under a pressure of at least 0.25 times the maximum allowable pressure (>1.04 MPa, max 4.15 MPa), for example, a universal sniffer.
• Electronic leak detectors may be used to detect fl ammable refrigerants, but the sensitivity may not be adequate, or may need re-calibration. (Detection equipment shall be calibrated in a refrigerant-free area.)
• Ensure that the detector is not a potential source of ignition and is suitable for the refrigerant used.
• Leak detection equipment shall be set at a percentage of the LFL of the refrigerant and shall be calibrated to the refrigerant employed and the appropriate percentage of gas (25 % maximum) is confirmed.
• Leak detection fluids are also suitable for use with most refrigerants, for example, bubble method and fluorescent method agents. The use of detergents containing chlorine shall be avoided as the chlorine may react with the refrigerant and corrode the copper pipe-work.
• 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. The precautions in #8 must be followed to remove the refrigerant.

8. 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 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 purged with OFN to render the appliance safe.
  • This process may need to be repeated several times.
• Compressed air or oxygen shall not be used for this task.
• Purging shall be achieved by breaking the vacuum in the system with OFN and continuing to fi ll until the working pressure is achieved, then venting to atmosphere, and fi nally pulling down to a vacuum.
• This process shall be repeated until no refrigerant is within the system.
• When the fi nal 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 potential ignition sources and there is ventilation available.

OFN = oxygen free nitrogen, type of inert gas.

9. 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 minimize the amount of refrigerant contained in them.
-Cylinders shall be kept in an appropriate position according to the instructions.
-Ensure that the refrigerating 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 over fi ll the refrigerating system.

• Prior to recharging the system it shall be pressure tested with OFN (refer to #7).
• 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.
• Electrostatic charge may accumulate and create a hazardous condition when charging and discharging the refrigerant. To avoid fire or explosion, dissipate static electricity during transfer by grounding and bonding containers and equipment before charging/discharging.

10. Decommissioning

• Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its details.
• 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 recovered 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 instructions.

h) Do not over fi II 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 refrigerating system unless it has been cleaned and checked.

- Electrostatic charge may accumulate and create a hazardous condition when charging or discharging the refrigerant. To avoid fire or explosion, dissipate static electricity during transfer by grounding and bonding containers and equipment before charging/discharging.

11. Labelling

• Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant.
• The label shall be dated and signed.
• Ensure that there are labels on the equipment stating the equipment contains fl ammable refrigerant.

12. 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.
• 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 fl ammable 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 fl ammable 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.

Water Filter Set

Outdoor unit

• Do not obstruct the air inlet and outlet vents. Failure to do so may result in low performance or system breakdown. Remove any obstruction to assure the ventilation.
• When it snows, clean and remove snow around the outdoor unit to prevent the air inlet and outlet vents from being covered with snow.

For extended non-use

• The water inside the Sanitary Water Tank should be drained.
• Disconnect the power supply.

Non serviceable criteria

Disconnect the power supply

then please consult an authorised dealer under the following conditions:

• Abnormal noise during operation.
- Water/foreign particles have entered the Remote Controller.
• Water leaks from the indoor unit.
- Circuit breaker switches off frequently.
- Power cord becomes excessively warm.

MAINTENANCE

User

• In order to ensure optimal performance of the units, user may inspect and clear any obstruction on the air inlet and outlet vents of the outdoor unit.
• Users should not try to service or replace parts of the unit.
• Contact authorised dealer for scheduled inspection.

Dealer

• In order to ensure safety and optimal performance of the units, seasonal inspections on the units, functional check of RCCB/ELCB, field wiring and piping have to be carried out at regular intervals by authorised dealer.
• Specific to the Sanitary Water Tank, it is important to service the Water Filter Set periodically.

Troubleshooting

The following symptoms do not indicate malfunction.

Symptom Cause
Water flowing sound during operation.	• Refrigerant flow inside the unit.
Operation is delayed a few minutes after restarting.	• The delay is a protection for the compressor.
Outdoor unit emits water/steam.	• Condensation or evaporation occurring in the pipes.
Steam comes out of the outdoor unit in the heating mode.	• It is caused by defrost operation in the heat exchanger.
Outdoor unit does not operate.	• It is caused by the protection control of the system when outdoor temperature is out of the operating range.
System operation switches off.	• It is caused by the protection control of the system. When the water inlet temperature is lower than 10 °C, the compressor stops and the backup heater power turns on.
System is hard to heat up.	• When the panel and the floor are heated simultaneously, warm water temperature may decrease, which may reduce the heating ability of the system.• When the outdoor air temperature is low, the system may need longer time to heat up.• Discharge outlet or intake inlet in the outdoor unit is blocked by some obstacle, such as a pile of snow.• When the preset water outlet temperature is low, the system may need longer time to heat up.
System does not heat up instantly.	• System will take some time to heat up the water if it starts to operate at cold water temperature.
Backup heater is automatically turned ON when it is disabled.	• It is caused by the protection control of the indoor unit heat exchanger.
Operation starts automatically when the timer is not set.	• Sterilization timer has been set.
Loud refrigerant noise continues for several minutes.	• It is caused by protection control during deice operation at outdoor ambient temperature lower than -10 °C.
COOL mode is unavailable.	• System has locked to operate in HEAT mode only.

Check the following before calling for servicing.

Symptom Check
Operation in HEAT mode is not working effi ciently.	Set the temperature correctly.Close the panel heater/cooler valve.Clear any obstruction in the air inlet and air outlet vents of the outdoor unit.
Noisy during operation.	Outdoor unit or indoor unit has been installed at an incline.Close the cover properly.
System does not work. • Circuit breaker	has tripped/activated.
Operation LED is not lit or nothing is displayed on the Remote Controller.	Power supply is working correctly, or a power failure has occurred.
