- The use of the air conditioner at a relative humidity above the expected one (80%) may cause the formation of condensate and the leakage of water drops on the floor.
Maintaining your air conditioner
Internal protections via the unit control system
This internal protection operates if an internal fault occurs in the air conditioner.
| Type Description | |
| Against cold air | The internal fan will be off to against cold air when the heat pump is heating. |
| De-ice cycle (Defrost cycle) | The internal fan will be off to against cold air when the heat pump is heating. |
| Anti-Freezing of Indoor Heat Exchanger | The compressor will be off if the heat exchanger temp of indoor unit decrease to 0°C or more to protect from ice build up on the heat exchanger. |
| Protect compressor | The air conditioner does not start operating immediately to protect the compressor of the outdoor unit after it has been started. |
- If the heat pump is operating in Heat mode, the De-ice cycle is actuated to remove frost from an outdoor unit that may have deposited at low temperatures. The internal fan is switched off automatically and restarted only after the de-ice cycle is completed.
Tips on using air conditioner
Here are some tips that you would follow when using your air conditioner.
| TOPIC RECOMMENDATION |
| Cooling | ·If current outside temperatures are much higher than the selected indoor temperature, it may take time to bring the inner temperature to the desired coolness.·Avoid drastically turning down the temperature. Energy is wasted and the room does not cool faster. |
| Heating | ·Since the air conditioner heats the room by taking heat energy from outdoor air, the heating capacity may decrease when outdoor temperatures are extremely low. If you feel the air conditioner insufficiently heats, using an additional heating appliance in combination with the air conditioner is recommended. |
| Frost & De-ice | ·When the air conditioner runs in Heat mode, due to temperature difference between the unit and the outside air, frost will form.If this happens:- The air conditioner stops heating.- The air conditioner will operate automatically in De-ice mode for 10 minutes.- The steam produced on the outdoor unit in De-ice mode is safe.No intervention is required; after about 10 minutes, the air conditioner operates again normally.※The unit will not operate when it starts to de-ice. |
| Fan | ·Fan may not operate for about 3~5 minutes at the beginning to prevent any cold blasts while the air conditioner is warming up. |
| High indoor/outdoor temperatures | ·If both indoor and outdoor temperatures are high and the air conditioner is running in Heat mode, the outdoor unit's fan and compressor may stop at times. This is normal; wait until the air conditioner turns on again. |
| Power failure | ·If a power failure occurs during the operation of the air conditioner, the operating immediately stops and unit will be off. When power returns, the air conditioner will run automatically. |
| Protection mechanism | ·If the air conditioner has just been turned on after operation stops or being plugged in, cool/warm air does not come out for 3 minutes to protect the compressor of the outdoor unit. |
| Automatic air flow blade control | ·If the air conditioner is operating in abnormal conditions (such as operating the air conditioner with windows open or when small capacity indoor unit is installed and operating in a room that is too large) indoor can become very humid when the angle of the air flow blade is small and performance of the product may decrease. When indoor humidity increases, indoor unit will automatically detect it and open the air flow blade in wider angle to make sure that performance of the product is stable. |

Cleaning and maintaining the air conditioner
Cleaning air filter and grille
Open the front grille.
Pull both hooks and take the grille downward. Two safety clips are mounted to the front grille to prevent it from dropping.
Detach the front grille.
Remove the safety clip from panel front. (There are two safety clips between grille and panel base.)
※ If you want to clean the filter only, you do not have to detach the grille. Follow step 4 and 5.
Clean the grille and air filter with a vacuum cleaner or soft brush. If dust is too heavy, then rinse it with running water and dry it in a ventilated area.
For best conditions, repeat every two weeks. If the air filter dries in a confined (or humid) area, odors may generate. If it occurs, re-clean and dry it in a well-ventilated area.
Pull out the air filter.
Insert the air filter back in its original position.
You will hear a click sound when the air filter is properly placed.
Attach the front grille.
Reverse the above steps to attach the front grille.
NOTE
• The illustration shown above may differ from yours depending on your model. - After cleaning the filter, press the Filter Reset button on the remote control for 2 seconds to reset the filter schedule. Filter sign indicator will be on for cleaning time. - If the angle on the air flow blades has been changed by user due to opening the front grille for installation or maintenance, you must turn off the circuit breaker and turn it on again before using the air conditioner. Otherwise, angles of the each angle can be different or some of the blade may not close when the product is off.
If the air conditioner will not be used for an extended period of time, dry the air conditioner to maintain it in best condition.
Dry the air conditioner thoroughly by operating in Fan mode for 3 to 4 hours and disconnect the power plug. There may be internal damage if moisture is left in components.

Indoor Unit Installation
It is recommended to install the Y-joint before installing the indoor unit.
- Place the pattern sheet on the ceiling at the spot where you want to install the indoor unit.
Note
Since the diagram is made of paper, it may shrink or stretch slightly due to temperature or humidity. For this reason, before drilling the holes maintain the correct dimensions between the markings.
- Insert bolt anchors, use existing ceiling supports or construct a suitable support as shown in figure.
- Install the suspension bolts depending on the ceiling type.
Ensure that the ceiling is strong enough to support the weight of the indoor unit. Before hanging the unit, test the strength of each attached suspension bolt.
If the length of suspension bolt is more than 1.5m, it is required to prevent vibration. If this is not possible, create an opening on the false ceiling in order to be able to use it to perform the required operations on the indoor unit.
- Screw eight nuts to the suspension bolts making space for hanging the indoor unit.
You must install more than four suspension bolts when installing the indoor unit.
- Check the level of the indoor unit by using a leveler.
◆ A tilt of the indoor unit may cause malfunction of a built-in float switch and water leaks.
- Adjust the height of the indoor unit by using the gauge of dimensions.
You should adjust the gauge of dimensions and the pattern sheet to fit the cutting dimensions of the ceiling. Make sure that the indoor unit is installed at a level; if the indoor unit slants too much, there can be water leaks.
4-way cassette
- Tighten the upper part nuts.
- Remove the gauge of dimensions after installing the indoor unit.
Leak test
LEAK TEST WITH NITROGEN (before opening valves): In order to detect basic refrigerant leaks, before recreating the vacuum and recirculating the R-410A, it is the responsibility of the installer to pressurize the whole system with nitrogen (using a pressure regulator) at a pressure above 4.1 MPa (gauge).
LEAK TEST WITH R-410A (after opening valves): Before opening valves, discharge all the nitrogen into the system and create vacuum. After opening valves, check leaks using a leak detector for refrigerant R-410A.
* The designs and shape are subject to change according to the model.
Discharge all the nitrogen to create a vacuum and charge the system.
Insulation
Once you have checked that there are no leaks in the system, you can insulate the piping and hose.
- To avoid condensation problems, place T13.0 or thicker Acrylonitrile Butadien Rubber separately around each refrigerant pipe.
Note: Always make the seam of pipes face upwards.
- Wind insulating tape around the pipes and drain hose avoiding to compress the insulation too much.
- Finish wrapping insulating tape around the rest of the pipes leading to the outdoor unit.
- The pipes and electrical cables connecting the indoor unit with the outdoor unit must be fixed to the wall with suitable ducts.
CAUTION
All refrigerant connections must be accessible, in order to permit either unit maintenance or removing it completely.
- Select the insulation of the refrigerant pipe.
◆ Insulate the gas side and liquid side pipe referring to the thickness according to the pipe size. - Indoor temperature of 30°C and humidity of 85% is the standard condition. If installing in a high humidity condition, use one grade thicker insulator by referring to the table below. - Insulator's heat-resistance temperature should be more than 120°C.
| Pipe Pipe size | Insulation Type (Heating/ Cooling) | RemarksStandard |
| [30°C, 85%] | High humidity [30°C, over 85%] |
| EPDM, NBR |
| Liquid pipe | ∅6.35 ~ ∅9.52 9t | 9t | | Internal temperature is higher than 120°C |
| ∅12.7 ~ ∅50.80 1 | 3t 13t | |
| Gas pipe | ∅6.35 13t | 9t | |
| ∅9.52 ~ ∅25.40 | 19t | 25t |
| ∅28.58 ~ ∅44.45 | 32t | |
| ∅50.80 25t | 38t | |
* When installing insulation in places and conditions below, use the same insulation that is used for high humidity conditions.
- High humidity places such as shoreline, hot spring, near lake or river, and ridge (when the part of the building is covered by earth and sand.)
- Restaurant ceiling, sauna, swimming pool etc.
- The ceiling frequently exposed to moisture and cooling is not covered.
e.g. The pipe installed at a corridor of a dormitory and
studio or near an exit that opens and closes frequently.
- The place where the pipe is installed is highly humid due to the lack of ventilation system.
◆ Install the insulation not to get wider and use the adhesives on the connection part of it to prevent moisture from entering. ◆ Wind the refrigerant pipe with insulation tape if it is exposed to outside sunlight. ◆ Install the refrigerant pipe respecting that the insulation does not get thinner on the bent part or hanger of pipe. - Add the additional insulation if the insulation plate gets thinner.
Drain pipe and Drain hose installation
- Install the drain pipe as shortly as possible.
- Give a slightly slant to the drainpipe for proper drainage of condensate water. There must be no gap on the connected part so that the drainpipe is not separated from the flexible hose.
- Insulate the drainpipe, and then fix it as indicated.
◆ Whole drainpipe should be insulated by 5t(or more) insulation to prevent water condensation.
* Flexible hose Installation
◆ Install horizontally
◆ Max. allowable axis gap
◆ Max. allowable bending angle
◆ Handle with using adhesive not to block the inside of flexible hose
Drainpipe Connection
- The drain pipe should be installed within 100mm from the flexible hose, lift up from 100mm to 550mm and lift down 20mm or more.
- Install horizontal drainpipe with a slope of 1/100 or more and fix it by hanger space of 1~1.5m.
- Install the air vent in the horizontal drainpipe to prevent water flow back to the indoor unit.
Note: You may not need to install it if there were proper slope in the horizontal drainpipe.
- The flexible hose should not be installed upward position, it may cause water flow back to the indoor unit.
- Install U-trap at the end of the drainpipe to prevent a nasty smell to reach the indoor unit.
Centralized Drainage
- Install main air vent at the front of the farthest indoor unit from the main drain when installed indoor units are more than 3.
- You may need to install individual air vent to prevent water flow back at the top of each indoor unit drainpipe.
Wire work
Power and communication cable connection
- Before wiring work, you must turn off all power sources.
- Indoor unit power should be supplied through a breaker (MCCB, ELB) separate from the outdoor power.
- The power cable should be made only of copper wires.
- Connect the power cable {1(L), 2(N)} among the units within the maximum length, and the communication cable (F1, F2) each.
- Connect F3, F4 (for communication) when installing the wired remote control.

(*1) Minimizing fan operation when thermostat is off
- Fan operates for 20 seconds at an interval of 5 minutes in heat mode.
(*2) 1: Fan is turned on continually when the hot water heater is turned on,
3: Fan is turned off when the hot water heater is turned on with cooling only indoor unit
Cooling only indoor unit: To use this option, install the Mode Select switch (MCM-C200) on the outdoor unit and fix it as cool mode.
(*3) When the following 2 or 3 is used as external heater On/Off signal, the signal for monitoring external contact control will not be output.
2: Fan is turned on continually when the external heater is turned on,
3: Fan is turned off when the external heater is turned on with cooling only indoor unit
Cooling only indoor unit: To use this option, install the Mode Select switch (MCM-C200) on the outdoor unit and fix it as cool mode.
- If Fan is set to off for cooling only indoor unit by setting the SEG9=3 or SEG15=3, you need to use an external sensor or wired remote controller sensor to detect indoor temperature exactly.
(*4) Default setting value
- 4Way Cassette, Mini 4Way Cassette: 5 °C
- Other indoor units: 2 °C
(*5) This function can be applied to 4 Way Cassette and Mini 4 Way Cassette only. If the air conditioner operates the heating mode immediately after finishing the cooling mode, the condensed water in the drain pan becomes water vapor by the heat of the indoor unit heat exchanger. Since the water vapor might be condensed on the indoor unit, which may fall into a living space, use this function to get rid of the water vapor out of the indoor unit by operating the fan (for maximum 20 minutes) even when the indoor unit is turned off after cooling mode is turned to heating mode.
- Do not install the electronic heater in the flow channel of the indoor unit fan.
