When Wiring
When Transporting
Be careful when picking up and moving the indoor and outdoor units. Get a partner to help, and bend your knees when lifting to reduce strain on your back. Sharp edges or thin aluminum fins on the air conditioner can cut your fingers.
When Installing…
Select an installation location which is rigid and strong enough to support or hold the unit, and select a location for easy maintenance.
…In a Room
Properly insulate any tubing run inside a room to prevent “sweating” that can cause dripping and water damage to walls and floors.
Keep the fire alarm and the air
CAUTION
…In Moist or Uneven Locations
Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the outdoor unit. This prevents
water damage and abnormal vibration.
…In an Area with High Winds
Securely anchor the outdoor unit down with bolts and a metal frame. Provide a suitable air baffle.
…In a Snowy Area (for Heat Pump-type Systems)
Install the outdoor unit on a raised platform that is higher than drifting snow. Provide snow vents.
outlet at least 5 feet (1.5 m) away from the unit.
When Connecting Refrigerant Tubing
• Pay particular attention to refrigerant leakages.
• Ventilate the room immediately, in the event that is refrigerant gas leaks during the installation. Be careful not to allow contact of the refrigerant gas with a flame as this will cause the generation of toxic gas.
• Keep all tubing runs as short as possible.
• Apply refrigerant lubricant to the matching surfaces of the flare and union tubes before connecting them, then tighten the nut with a torque wrench for a leak-free connection.
• Check carefully for leaks before starting the test run.
WARNING
• When performing piping work, do not mix air except for specified refrigerant (R410A) in refrigeration cycle. It causes capacity down, and risk of explosion and injury due to high tension
inside the refrigerant cycle.
• If the refrigerant comes in contact with a flame, it produces a toxic gas.
• Do not add or replace refrigerant other than specified type. It may cause product damage, burst and injury, etc.
2
• Do not leak refrigerant while piping work for an installation or re-installation, and while repairing refrigeration parts. Handle liquid refrigerant carefully as it may cause
frostbite.
When Servicing
• Turn the power OFF at the main power box (mains) before opening the unit to check or repair electrical parts and wiring.
• Keep your fingers and clothing away from any moving parts.
• Clean up the site after you finish, remembering to check that no metal scraps or bits of wiring have been left inside the unit.
CAUTION
• Do not touch the air inlet or the sharp aluminum fins of the outdoor unit. You may get injured.
• Ventilate any enclosed areas when installing or testing the refrigeration system. Leaked refrigerant gas, on contact with fire or heat, can produce dangerously toxic gas.
• Confirm after installation that no refrigerant gas is leaking. If the gas comes in contact with a burning stove, gas water heater, electric room heater or other heat source, it can cause the generation of toxic gas.
WARNING
• This product must not be modified or disassembled under any circumstances. Modified or disassembled unit may cause fire, electric shock or injury.
• Do not clean inside the indoor and outdoor units by users. Engage authorized dealer or specialist for cleaning.
• In case of malfunction of this appliance, do not repair by yourself. Contact to the sales dealer or service dealer for a repair.
Check of Density Limit
The room in which the air conditioner is to be installed requires a design that in the event of refrigerant gas leaking out, its density will not exceed a set limit.
The refrigerant (R410A), which is used in the air conditioner, is safe, without the toxicity or combustibility of ammonia, and is not restricted by laws imposed to protect the ozone layer. However, since it contains more than air, it poses the risk of suffocation if its density should rise excessively. Suffocation from leakage of refrigerant is almost non-existent. With the recent increase in the number of high density buildings, however, the installation of multi air conditioner systems is on the increase because of the need for effective use of floor space, individual control, energy conservation by curtailing heat and carrying power, etc. Most importantly, the multi air conditioner system is able to replenish a large amount of refrigerant compared to conventional individual air conditioners.
Others
WARNING
• Do not sit or step on the unit, you may fall down accidentally.
CAUTION
• Do not touch the air inlet or the sharp aluminum fins of the outdoor unit. You may get injured.
• Do not stick any object into the FAN CASE. You may be injured and the unit may be damaged.
If a single unit of the multi air conditioner system is to be installed in a small room, select a suitable model and installation procedure so that if the refrigerant accidentally leaks out, its density does not reach the limit (and in the event of an emergency, measures can be made before injury can occur). ASHRAE and the International Mechanical Code of the ICC as well as CSA provide guidance and define safeguards related to the use of refrigerants, all of which define a Refrigerant Concentration Level (RCL) of 25 pounds (11.3 kg) per 1,000 cubic feet (28.3 m R410A refrigerant. For additional guidance and precautions related to refrigerant safety, please refer to the following documents:
International Mechanical Code 2012 (IMC-2012) (or more recently revised) ASHRAE 15 ASHRAE 34

AVOID:
● areas where leakage of flammable gas may be expected.
● places where large amounts of oil mist exist.
● direct sunlight.
● locations near heat sources which may affect the performance of the unit.
● locations where external air may enter the room directly.
This may cause “condensation” on the air discharge ports, causing them to spray or drip water.
● locations where the remote controller will be splashed with water or affected by dampness or humidity.
● installing the remote controller behind curtains or furniture.
● locations where high-frequency emissions are generated.
DO:
● select an appropriate position from which every corner of the room can be uniformly cooled.
● select a location where the ceiling is strong enough to support the weight of the unit.
● select a location where tubing and drain pipe have the shortest run to the outdoor unit.
● allow room for operation and maintenance as well as unrestricted air flow around the unit.
● install the unit within the maximum elevation difference above or below the outdoor unit and within a total tubing length (L) from the outdoor unit as detailed in the installation manual packed with the outdoor unit.
● allow room for mounting the remote controller about 3.3 ft. (1 m) off the floor, in an area that is not in direct sunlight or in the flow of cool air from the indoor unit.
● if the indoor unit is installed on the ceiling where the temperature or humidity inside is high (over 86°F(30°C)/RH: 70%), add insulating material to the surface of the unit to avoid dew condensation.
● keep the fire alarm and the air outlet at least 5 ft. (1.5 m) away from the unit.

3-3. Placing the Unit Inside the Ceiling
This unit is equipped with the drain pump. Check a tape measure or carpenter’s level. Before installing the ceiling panel, complete the work of drain pipe and refrigerant pipe installation.
(1) When placing the unit inside the ceiling, determine the
pitch of the suspension bolts using the supplied full-scale installation diagram. (Fig. 3-4) Tubing and wiring must be laid inside the ceiling when suspending the unit. If the ceiling is already constructed, lay the tubing and wiring into position for connection to the unit before placing the unit inside the ceiling.
(2) The length of suspension bolts must be appropriate for a
distance between the bottom of the bolt and the bottom of the unit of more than 45/64” (18 mm) as shown in Fig. 3-4.
(3) Thread the 3 hexagonal nuts and 2 washers (field supply)
onto each of the 4 suspension bolts as shown in Fig. 3-5.
Use 1 nut and 1 washer for the upper side, and 2 nuts and 1
washer for the lower side, so that the unit will not fall off the suspension lugs.
(4) Adjust so that the distance between the unit and the ceiling
bottom is 15/32” (12 mm) ~ 43/64” (17 mm). Tighten the nuts on the upper side and lower side of the suspension lug.
(5) Remove the protective polyethylene used to protect the fan
parts during transport.
(6) Check with a tape measure or carpenter’s level.

3-5. Installing the Drain Pipe
3-5-1. Before Performing the Installation Drain Piping
(1) Limitations of Raising the Drain Pipe Connection
CAUTION
The drain pipe can be raised to a maximum height of
2.79 ft. (850 mm) from the bottom surface of the ceiling. Do not attempt to raise it higher than 2.79 ft. (850 mm). Doing so will result in water leakage. (Fig. 3-6)
(2) Limitations of Drain Pipe Connection
CAUTION
Do not install the drain pipe with an upward gradient from the drain port connection. This will cause the drain water to flow backward and leak when the unit is not operating. (Fig. 3-7)
Do not install an air bleeder as this may cause water to spray from the drain pipe outlet. (Fig. 3-7)
Do not provide U-trap or bell-shaped trap in the middle of the drain pipe. Doing so will cause abnormal sound. (Fig. 3-7)
Make sure the drain pipe has a downward gradient (1/100 or more; downward from drain port connection). (Fig. 3-8)

3-5-2. Installing the Drain Hose
CAUTION
Do not apply force to the drain port when connecting the drain hose. Install and fix it near the indoor unit as close as possible.
Do not use adhesive when connecting the drain port pipe and the drain hose.
(1) How to Install the Drain Hose
1) First insert the supplied hose band into the drain port pipe. Then make sure the head of the screw is facing toward a technical engineer when placing the screw of the hose band at an upward angle.
2) Insert the soft PVC socket of the supplied drain hose to the drain port pipe. Do not use adhesive when connecting the drain hose to the drain port pipe. Insert it until the tip of the drain hose contacts the circular projection rib of the drain port pipe.
3) Move the hose band so that the center position of the hose band can be placed approx. 1-3/16” (30 mm) away from the external plate of the indoor unit. (Fig. 3-11)
4) Screw the drain hose tightly facing the screw of the hose band upward. (Torque: 22 - 30 lbf·inch (2.5 N·m - 3.4 N·m)) (If the screw is tightened beneath the drain hose, the troubles will be generated.) Pay attention not to make hose band overlap the circular projection rib and the sealed circulation projection of the drain port hose.
5) Move the drain socket showing in the direction of the arrow toward the drain hose and connect with the adhesive (approx. 0.07 oz (2g)).
6) Then connect the hard PVC pipe (field supply) on the opposite side of the drain socket. Apply the adhesive (approx. 0.07 oz (2g)) between the two parts. After connection, remove sticky adhesive left over the surface.
