Do not insert your fingers or other objects into the unit, high speed rotating fan may cause injury.
Do not sit or step on the unit, you may fall down accidentally.
Keep plastic bag (packaging material) away from small children, it may cling to nose and mouth and prevent breathing.
When installing or relocating air conditioner, do not let any substance other than the specified refrigerant, eg. air etc mix into refrigeration cycle (piping). Mixing of air etc. will cause abnormal high pressure in refrigeration cycle and result in explosion, injury etc.
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.
Do not add or replace refrigerant other than specified type. It may cause product damage, burst and injury etc.
For R410A model, use new piping, flare nut and tools which is specified for R410A refrigerant. Using of existing (R22) piping, flare nut and tools may cause abnormally high pressure in the refrigerant cycle (piping), and possibly result in explosion and injury. For R32 and R410A, the same flare nut on the outdoor unit side and pipe can be use.
Since the working pressure for R32/R410A is higher than that of refrigerant R22 models, replacing conventional piping and flare nuts on the outdoor unit side are recommended.
Thickness for copper pipes used with R410A must meet the requirement. Refer to 1 GENERAL piping thickness table in outdoor unit installation manual. It is desirable that the amount of residual oil less than 40 mg/10 m.
Engage authorized dealer or specialist for installation. If installation done by the user is incorrect, it will cause water leakage, electrical shock or fire.

PRECAUTION FOR USING R410A REFRIGERANT
· The basic installation work procedures are the same as conventional refrigerant (R32, R22) models.
However, pay careful attention to the following points:
Do not perform flare connection inside a building or dwelling or room, when joining the heat exchanger of indoor unit with interconnecting piping. Refrigerant connection inside a building or dwelling or room must be made by brazing or welding. Joint connection of indoor unit by flaring method can only be made at outdoor or at outside of a buidling or dwelling or room. Flare connection may cause gas leak and flammable atmosfere.
The appliance shall be stored, installed and operated in a well ventilated room with indoor floor area larger than Amin (m²) [Refer to Check of Density Limit] and without any continuously operating ignition source. Keep away from open flames, any operating gas appliances or any operating electric heater. Else, it may explode and cause injury or death.
Refer to "PRECAUTION FOR USING R410A REFRIGERANT" in outdoor unit installation manual for other precautions that need to pay attention to.
Check of Density Limit
WARNING CAUTION
Always check the gas density limit for the room in which the unit is installed.
Pay special attention to any location, such as a basement, etc., where leaking refrigerant can accumulate, since refrigerant gas is heavier than air.
When installing an air conditioner in a room, it is necessary to ensure that even if the refrigerant gas accidentally leaks out, its density does not exceed the limit level for that room. If the density could exceed the limit level, it is necessary to provide an opening between the unit and the adjacent room, or to install mechanical ventilation which is interlocked with a leak detector.
(Total refrigerant charged amount: kg)
(Min. indoor volume where the indoor unit is installed: m³)
Limit density 0.44 (kg/m³)
The limit density of refrigerant R410A which is used in this unit is 0.44 kg/m³ (ISO 5149). The shipped outdoor unit comes charged with the amount of refrigerant fixed for each type, so add it to the amount that is charged in the field. (For the refrigerant charge amount at shipment, refer to the unit's nameplate.) Minimum indoor volume & floor area as against the amount of refrigerant is roughly as given in the following table.
Checking of limit density
Density limit is determined on the basis of the size of a room using an indoor unit of minimum capacity. For instance, when an indoor unit is used in a room (floor area 15 m2 × ceiling height 2.7 m = room volume 40.5 m3), the graph at right shows that the maximum overall refrigerant charge amount of limit density (0.44 kg/m3) that is not required to install a ventilation fan should be calculated as follows.
Due to the room volume, Maximum overall refrigerant charge amount
= (room volume) × (limit density) = 40.5 (m3) × 0.44 (kg/m3) = 17.82 kg
m2
m3
85 229.5
80 216.0
75 202.5
Overall refrigerant charge amount for this system is 72.709 (kg). The formula for the minimum room volume should be determined as follows.
Required minimum room volume = (overall refrigerant charge amount) ÷ (limit density) = 72.709 (kg) ÷ 0.44 (kg/m3) = 165.25 (m3)
Required minimum floor area = (minimum room volume) ÷ (ceiling height) = 165.25 (m3) ÷ 2.7 (m) = 61.2 (m2)
Therefore an opening for ventilation is required.

2-4. Installing the Drain Piping
2-4-1. Before Performing the Installation Drain Piping
(1) (Prepare standard hard PVC pipe (O.D. 32 mm) for the drain and use the supplied drain socket to prevent water leaks. The PVC pipe must be purchased separately. When doing this, apply adhesive for the PVC pipe at the connection point. See section "2-4-2. Installing the Drain Pipe".
(2) Limitations of Drain Hose Connection
(3) Ensure the drain pipe has a downward slant (1/100 or more).
CAUTION Do not make a trap in the middle of the supplied drain pipe. Doing so will cause abnormal sound.
Downward slant Min. 1/100
Trap prohibited
Correct
Incorrect
(4) The drain pipe with a trap should be installed away from the indoor unit. (5) Do not attach any air purge equipment.
If attached, drain water may result in splashing out of the drain pipe. (6) When the drain piping is completed, perform the water leak test and check for a
water leak. If detected, it may result in water leakage or condensation. (7) When the drain piping is completed, perform the drainage test if the water drains smoothly. If not draining smoothly, it may result in water leakage or condensation. (8) When the drain piping work is finished securely, wrap the insulation material around the indoor side drain pipe. At this time, do not wrap together with the refrigerant tubing. If wraped together, the drain pipe is lifted and water drainage will not be operated. Consequently, the water comes out of the drain pan and it can lead to water leakage.

4 REFRIGERANT PIPING
Must ensure mechanical connections be accessible for maintenance purposes. The liquid tubing side is connected by a flare nut, and the gas tubing side is connected by brazing.
4-1. Connecting the Refrigerant Tubing
Cautions During Brazing
· Replace air inside the tube with nitrogen gas to prevent copper oxide film from forming during the brazing process. (Oxygen, carbon dioxide and Freon are not acceptable.)
· Do not allow the tubing to get too hot during brazing. The nitrogen gas inside the tubing may overheat, causing refrigerant system valves to become damaged. Therefore allow the tubing to cool when brazing.
· Use a reducing valve for the nitrogen cylinder. · Do not use agents intended to prevent the formation of oxide film. These agents adversely affect the refrigerant and refrigerant
oil, and may cause damage or malfunctions.
4-2. Connecting Tubing Between Indoor and Outdoor Units
(1) Tightly connect the indoor-side refrigerant tubing extended from the wall with the outdoor-side tubing. Indoor Unit Tubing Connection

(2) To fasten the flare nuts, apply specified torque.
Torque wrench
· When removing the flare nuts from the tubing connections, or when tightening them after connecting the tubing, be sure to use a torque wrench and a spanner. If the flare nuts are over-tightened, the flare

Spanner
may be damaged, which could result in refrigerant leakage and cause injury or asphyxiation to room
occupants. · For the flare nuts at tubing connections, be sure to use the flare nuts that were supplied with the unit,
Outdoor unit
or else flare nuts for R410A, R32 (type 2). The refrigerant tubing that is used must be of the correct wall thickness as shown in the table
below.
Tube diameter ø12.7 (1/2")
Flare nut tightening torque (approximate) 55±6 N·m {550±60 kgf·cm}
Min. tube thickness 0.8 mm (Material Temper - O)
ø19.05 (6/8")
1.2 mm (Material Temper - O)
ø22.22 (7/8")
1.0 mm (Material Temper - 1/2 H · H)
· Because the pressure is approximately 1.6 times higher than conventional refrigerant R22 pressure, the use of ordinary flare nuts (type 1) or thin-walled tubes may result in tube rupture, injury, or asphyxiation caused by refrigerant leakage.
· In order to prevent damage to the flare caused by over-tightening of the flare nuts, use the table above as a guide when tightening. · When tightening the flare nut on the liquid tube, use an adjustable wrench with a nominal handle length of 200 mm.
4-3. Insulating the Refrigerant
CAUTION Be sure to perform heat insulation on the drain, liquid and gas piping. Imperfection in heat insulation work leads to water leakage.
(1) Selection of heat insulation materials for refrigerant tube. When using heat insulation materials (field supply), kindly check for its sizes and performance.
· Material for insulation material: Polyethylene foam. · Heat transfer rate: less than 0.051W/m·K. · Material withstand temperature: 120°C or above (gas tubing).
For other tubing 80°C or above · Must be easy to use, age resistance and not easily absorb moisture. · Be sure to match the below insulation material size with tube sizes.
Piping size, mm (In) 12.7 (1/2")
Thermal insulation size (I.D.) 14 ~ 16 mm
Thermal insulation Thickness
19.05 (3/4")
20 ~ 24 mm
Insulation thickness must be 10mm or greater
ø22.22 (7/8")
22 ~ 25 mm
(2) Taping the flare nuts
· Wind the white insulating tape around the flare nuts at the gas tube connection. · Then cover up the tubing connection with tube insulator (field supply) and fill in the
gap with black insulation tape. · Finally fasten with clampers (field supply)
Flare insulator (Field supply) Flare union
Unit side
NOTE
If noise bothers you from the area between indoor and outdoor units' connection pipes, it is effective to wind the soundproofing materials (field supply) to reduce noise.
Tube insulator (Field supply) Flare nut Heat resistant 120°C or above
CAUTION After a tube has been insulated, never try to bend it into a narrow curve because it can cause the tube to break or crack. Never grasp the drain or refrigerant connecting outlets when moving the unit.
(3) Taping the tubes · Refrigerant tubes (and electrical wiring if local permit) should be taped together with armouring
tape in 1 bundle. Keep the drain hose separate from refrigerant tube to prevent condensation. · Wrap the armouring tape from bottom of the outdoor unit to the tubing here it enters the wall.
Overlap half of each previous turn. · Clamp the tubing to the wall, using 1 clamp approx. per each meter apart.
NOTE
Do not wind the armouring tape too tightly since this will decrease the heat insulation effect. Also ensure that the condensation drain hose splits away from the bundle and drips clear of the unit and the tubing.

(4) Finishing the Installation
· After finishing insulating and taping over the tubing, use sealing putty to seal off the hole in the wall to prevent rain and draft from entering.
(5) Precautions in high humidity circumstances
· This air-conditioner has been tested according to the "JIS Standard Conditions with Mist" and have been confirmed that there are no faults. However, if it is operated for a long time in high humid atmosphere (dew point temperature: more than 23 °C ), water drops are liable to fall. In this case, add heat insulation material according to the following procedures: 1. Heat insulation material to be prepared. Adiabatic glass wool with thickness 10~20mm
2. Stick the wool on all air-conditioners that are located in the ceiling atmosphere
3. In addition to the normal heat insulation (thickness: more than 10mm) refrigerant piping, add a further of 10~30 mm thickness material.
Apply putty here Tubing
4-4. Additional Precautions for R410A models
For connection joint of all models Please make flare after inserting flare nut (locate at joint portion of tube assembly) onto the copper pipe. (In case of using long piping) Connect the piping
· Align the center of piping and sufficiently tighten the flare nut with fingers. · Further tighten the flare nut with torque wrench in specified torque as stated in the table.
Spanner or Wrench
