Product Usage Instructions
1. Safety Precaution
Cautions for units utilizing refrigerant R410A:
- Do not use the existing refrigerant piping to prevent lubricant deterioration.
- Use low residual oil piping to avoid lubricant deterioration.
- Store the piping indoors and seal both ends until just before brazing to prevent contamination.
- Apply ester oil, ether oil, or alkylbenzene oil in a small amount to flare and flange connections.
- Charge refrigerant from the liquid phase of a gas cylinder to maintain efficiency.
- Do not use refrigerant other than R410A to prevent deterioration of refrigerant oil.
- Use a vacuum pump with a reverse flow check valve to prevent the flow back of vacuum pump oil into the refrigerant cycle.
2. Parts Names and Functions
Detailed information on the various parts and their functions can be found in the manual.
3. 4-Way Air Flow System
The air conditioner features a 4-way air flow system for efficient cooling and heating distribution.
FAQs
- Q: Can I use refrigerant other than R410A in the air conditioner?
- A: No, using refrigerant other than R410A can cause deterioration of the refrigerant oil and may lead to system inefficiency.
- Q: How should I store the refrigerant piping?
- A: Store the piping indoors and ensure both ends are sealed until just before brazing to prevent contamination.

SAFETY PRECAUTION
Cautions for units utilizing refrigerant R410A
Do not use the existing refrigerant piping.
The old refrigerant and lubricant in the existing piping contain a large
amount of chlorine which may cause the lubricant deterioration of the new
unit.
Use “low residual oil piping”
If there is a large amount of residual oil (hydraulic oil, etc.) inside the
piping and joints, deterioration of the lubricant will result.
Store the piping indoors, and both ends of the piping sealed until just before
brazing. (Leave elbow joints, etc. in their packaging.) If dirt, dust orr

Charge refrigerant from liquid phase of gas cylinder. If the refrigerant is
charged from gas phase, composition change may occur in refrigerant and the
efficiency will be lowered.
Do not use refrigerant other than R410A.
If other refrigerant (R22, etc.) is used, chlorine in refrigerant can cause
deterioration of refrigerant oil, etc.
Use a vacuum pump with a reverse flow check valve.
Vacuum pump oil may flow back into refrigerant cycle and that can cause
deterioration of refrigerant oil, etc.
Use the following tools specifically designed for use with R410A refrigerant.
The following tools are necessary to use R410A refrigerant.
Tools for R410A
Gauge manifold
Flare tool
Charge hose
Size adjustment gauge
Gas leak detector
Vacuum pump adaptor
Torque wrench
Electronic refrigerant

Handle tools with care.

Use the specified refrigerant only.
Never use any refrigerant other than that specified. Doing so may cause a
burst, an explosion, or fire when the unit is being used, serviced, or
disposed of. Correct refrigerant is specified in the manuals and on the spec
labels provided with our products. We will not be held responsible for
mechanical failure, system malfunction, unit breakdown or accidents caused by
failure to follow the instructions.
Ventilate the room if refrigerant leaks during operation. If refrigerant comes into contact with a flame, poisonous gases will be released.

[1] Cautions for service
(1) Perform service after recovering the refrigerant left in unit completely.
(2) Do not release refrigerant in the air. (3) After completing service,
charge the cycle with specified amount of refrigerant. (4) When performing
service, install a filter drier simultaneously.
Be sure to use a filter drier for new refrigerant.
[2] Additional refrigerant charge
When charging directly from cylinder (1) Check that cylinder for R410A
available on the market is syphon type. (2) Charging should be performed with
the cylinder of syphon stood vertically. (Refrigerant is charged from liquid
phase.)

WAY AIR FLOW SYSTEM
4-1. PLACEMENT OF THE AIR OUTLETS
· For this grille, the blowout direction comes in 11 patterns. Also, by
setting switch on the controller board to the appropriate settings, you can
adjust the airflow and speed. Select the settings from Table1 according to the
location in which you want to install the unit.
- Decide on the pattern of the airflow direction.
<Table 1>

Note1. For 3- and 2-direction settings, please use the air outlet shutter
plate (option).
2) According to the number of air outlets and height of the ceiling to install
the unit, be sure to set up the switch (SW21) on the circuit board to the
appropriate setting. · Correspondence of ceiling heights to the number of air

At the time of installation, use the duct holes (cut out) located at the
positions shown in following diagram, as and when required. · A fresh air
intake hole for the optional multi-functional casement can also be made.
Note: The figures marked with * in the drawing below represent the dimensions of the main unit excluding those of the optional multifunctional casement. When installing the optional multifunctional casement, add 135 mm to the dimensions marked on the figure. When installing the branch ducts, be sure to insulate adequately. Otherwise, condensation and dripping may occur.

· Whenever the indoor unit is operating, the duct fan also operates. (1)
Connect the optional multiple remote controller adapter (PAC-SA88HA-E) to the
connector CN51 on the indoor controller board. (2) Drive the relay after
connecting the 12 V DC relay between the Yellow and Orange connector lines.

NOTES:
1. At servicing for outdoor unit, always follow the wiring
diagram of outdoor unit.
2. In case of using MA-Remote controller, please connect
to TB15. (Remote controller wire is non-polar.)
3. In case of using ME-Remote controller, please connect
to TB5. (Transmission line is non-polar.)
4. Symbol [S]of TB5 is the shield wire connection.
5. Symbols used in wiring diagram above are,
: terminal block,
: connector.
6. The setting of SW2 differs in the capacity and model.
For the detail, refer to the table 1.
7. Make sure to turn off the indoor and the outdoor units
before replacing indoor controller board.

1 Check if the drain float switch works properly. 2 Check if the drain pump
works and drains water properly in cooling operation. 3 If no water drains,
confirm that the check code 2502 will not be displayed 10 minutes after the
operation starts. Note: The drain pump for this model is driven by the
internal DC motor of controller board, so it is not
possible to measure the resistance between the terminals.

i-see Sensor
Turn the power ON while the i-see Sensor connector is connected to the CN4Z on indoor controller board. A communication between the indoor controller board and i-see Sensor board is made to detect the connection.
Normal: When the operation starts, the motor for i-see Sensor is driven to rotate the i-see Sensor. Abnormal: The motor for i-see Sensor is not driven when the operation starts.
