IMPORTANT!
Please Read Before Starting
This air conditioning system meets strict safety and operating standards. As the installer or service person, it is an important part of your job to install or service the system so it operates safely and efficiently.
For safe installation and trouble-free operation, you must:
●Carefully read this instruction booklet before beginning.
●Follow each installation or repair step exactly as shown.
●Observe all local, state, and national electrical codes.
●Pay close attention to all warning and caution notices given in this manual.
This symbol refers to a hazard or
WARNING unsafe practice which can result in severe personal injury or death.
This symbol refers to a hazard or
CAUTION
unsafe practice which can result in personal injury or product or property damage.
If Necessary, Get Help
These instructions are all you need for most installation sites and maintenance conditions. If you require help for a special problem, contact our sales/service outlet or your certified dealer for additional instructions.
In Case of Improper Installation
The manufacturer shall in no way be responsible for improper installation or maintenance service, including failure to follow the instructions in this document.
SPECIAL PRECAUTIONS
WARNING When Wiring
ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY A QUALIFIED, EXPERIENCED ELECTRICIAN SHOULD ATTEMPT TO WIRE THIS SYSTEM.
•Do not supply power to the unit until all wiring and tubing are completed or reconnected and checked.
•Highly dangerous electrical voltages are used in this system. Carefully refer to the wiring diagram and these instructions when wiring. Improper connections and inadequate grounding can cause accidental injury or death.
•Ground the unit following local electrical codes.
•Connect all wiring tightly. Loose wiring may cause overheating at connection points and a possible fire hazard.
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…
…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.
…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.
When Connecting Refrigerant Tubing
•Ventilate the room well, 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 poisonous gas.
•Keep all tubing runs as short as possible.
•Use the flare method for connecting tubing.
•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.
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.
CAUTION
•Clean up the site after you finish, remembering to check that no metal scraps or bits of wiring have been left inside the unit being serviced.
•Ventilate any enclosed areas when installing or testing the refrigeration system. Escaped 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 poisonous gas.

07-115 SSHP_II 5/7/07 3:59 PM Page 3
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. 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).
In a room where the density may exceed the limit, create an opening with adjacent rooms, or install mechanical ventilation combined with a gas leak detection device. The density is as given below.
Total amount of refrigerant (oz.)
Min. volume of the indoor unit installed room (ft.3)
< Density limit (oz./ft.3)
The density limit of refrigerant which is used in multi air conditioners is 0.3 oz./ft.3 (ISO 5149).
NOTE
1.If there are 2 or more refrigerating systems in a single refrigerating device, the amount of refrigerant should be as charged in each independent device.
For the amount of charge in this example:
Outdoor unit
e.g., charged
amount (22 lbs.) e.g., charged amount (33 lbs.)
Indoor unit
Room A Room B Room C Room D Room E Room F
The possible amount of leaked refrigerant gas in rooms A, B and C is 22 lbs.
The possible amount of leaked refrigerant gas in rooms D, E and F is 33 lbs.
2.The standards for minimum room volume are as follows.
(1) No partition (shaded portion)
(2)When there is an effective opening with the adjacent room for ventilation of leaking refrigerant gas (opening without a door, or an opening 0.15% or larger than the respective floor spaces at the top or bottom of the door).
Outdoor unit
Refrigerant tubing
Indoor unit |
(3)If an indoor unit is installed in each partitioned room and the refrigerant tubing is interconnected, the smallest room of course becomes the object. But when mechanical ventilation is installed interlocked with a gas leakage detector in the smallest room where the density limit is exceeded, the volume of the next smallest room becomes the object.

Precautions for Installation Using New Refrigerant
1. Care regarding tubing
1-1. Process tubing
●Material: Use C1220 phosphorous deoxidized copper specified in JIS H3300 “Copper and Copper Alloy Seamless Pipes and Tubes.”
●Tubing size: Be sure to use the sizes indicated in the table below.
●Use a tube cutter when cutting the tubing, and be sure to remove any flash. This also applies to distribution joints (optional).
●When bending tubing ø5/8" or smaller, use a bending radius that is 4 times the outer diameter of the tubing or larger.
Use sufficient care in handling the tubing. Seal the tubing ends with CAUTION caps or tape to prevent dirt, moisture, or other foreign substances
from entering. These substances can result in system malfunction.

1-2. Prevent impurities including water, dust and oxide from entering the tubing. Impurities can cause R410A refrigerant deterioration and compressor defects. Due to the features of the refrigerant and refrigerating machine oil, the prevention of water and other impurities becomes more important than ever.
2. Be sure to recharge the refrigerant only in liquid form.
2-1. Since R410A is a non-azeotrope, recharging the refrigerant in gas form can lower performance and cause defects of the unit.
2-2. Since refrigerant composition changes and performance decreases when gas leaks, collect the remaining refrigerant and recharge the required total amount of new refrigerant after fixing the leak.
3. Different tools required
3-1. Tool specifications have been changed due to the characteristics of R410A. Some tools for R22and R407C-type refrigerant systems cannot be used.

1-3. Type of Copper Tube and Insulation Material
Copper tubing for connecting the outdoor unit to the indoor unit is available in kits which contain the liquid and gas tubing, fittings and insulation. Consult your nearest sales outlet or A/C workshop.
If you wish to purchase these materials separately from a local source, you will need:
1.Deoxidized annealed copper tube for refrigerant tubing.
2.Foamed polyethylene insulation for copper tubes as required to precise length of tubing.
Wall thickness of the insulation should be not less than 5/16 in.
3.Use insulated copper wire for field wiring. Wire size varies with the total length of wiring. Refer to Section 5. “Electrical Wiring” for details.
CAUTION Check local electrical codes and regulations before
obtaining wire. Also, check any specified instructions or limitations.
1-4. Additional Materials Required for Installation
1.Refrigeration (armored) tape
2.Insulated staples or clamps for connecting wire (See your local codes.)

CAUTION
WARNING
1.This unit requires no additional refrigerant charge up to 100 ft. tubing length. In case of more than 100 ft., additional refrigerant charge is required. Refer to Table 1-11.
2.In case of multi type installation, indoor units should be installed within the same room. If multi type indoor units are installed in different rooms, temperature control may develop problems because thermostat operation must follow the thermostat condition of 1 indoor unit only (the main unit).
Always check the gas density for the room in which the unit is installed.
■ Check of limit density
When installing an air conditioner in a room, it is necessary to ensure that even if the refrigerant gas accidentally escapes, its density does not exceed the limit level. If the density might exceed the limit level, it is necessary to set up an opening between it and the adjacent room, or to install mechanical ventilation which is interlocked with the leak detector.
(Total refrigerant charged amount: oz.)
(Min indoor volume where the indoor unit is installed: ft.3) < Limit density 0.3 (oz./ft.3)
The limit density of refrigerant which is used in this unit is 0.3 oz./ft.3 (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 at the field. (For the refrigerant charge amount at shipment, refer to the unit’s nameplate.)
Minimum indoor volume & floor area relative to the amount of refrigerant is roughly as given in the following table.

2. SELECTING THE INSTALLATION SITE
2-1. Indoor Unit
AVOID:
●areas where leakage of flammable gas may be expected.
●places where large amounts of oil mist exist.
●direct sunlight.
●locations near inverter lamps which may affect the performance of the unit.
●locations near heat sources which may affect the performance of the unit.
●locations where external air may enter the room directly. This may cause “sweating” on the air discharge ports, causing them to spray or drip.
●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 the receiver in the indoor unit is exposed to the inverter lamp light. Faulty operation of the unit occurs.
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 Table 1-11.
●allow room for mounting the remote controller about 3 ft. off the floor, in an area that is not in direct sunlight nor in the flow of cool air from the indoor unit.
NOTE
Air delivery will be degraded if the distance from the floor to the ceiling is greater than 10 ft.

2-2. Outdoor Unit
AVOID:
●heat sources, exhaust fans, etc. (Fig. 2-1)
●damp, humid or uneven locations
DO:
●choose a place as cool as possible.
●choose a place that is well ventilated and outside air temperature does not exceed maximum 115°F constantly.
●allow enough room around the unit for air intake/ exhaust and possible maintenance. (Fig. 2-2)
●use lug bolts or equal to bolt down unit, reducing vibration and noise.
●if cooling operation is to be used when the outdoor air temperature is 23°F or below, install a duct on the outdoor unit.

● Concerning inlet-side distance “C” (Fig. 2-2)
CAUTION
The minimum for distance “C” is 6" if there are no obstructions on the outlet side (wall *1 side) and *2 or *4 is not present. In all other cases, the minimum for distance “C” is 8".
●If the unit is installed with the outlet side facing wall *1, then there must be no obstructions on 2 of the remaining 3 sides: *2, *3, *4.
●If wall *1 is on the outlet side (Fig. 2-2), or if obstructions are present on all 3 sides *2, *3, and *4 (Fig. 2-2), then the minimum distance for “A” and “B” is 80" (Fig. 2-3). Even if there is no wall on the outlet side, a minimum of 3.3 ft. is required.
Installation requirements
●provide a solid base (concrete block, 4" × 16" beams or equal), a minimum of 6" above ground level to reduce humidity and protect the unit against possible water damage and decreased service life. (Fig. 2-4)
●use lug bolts or equal to bolt down unit, reducing vibration and noise.

07-115 SSHP_II 5/7/07 3:59 PM Page 18
2-3. Air-Discharge Chamber for Top Discharge
Be sure to install an air discharge chamber in the field when:
●it is difficult to keep a space of min. 20" between the air discharge outlet and an obstacle.
●the air discharge outlet is facing a sidewalk and discharged hot air may bother passers-by. Refer to Fig. 2-5.
2-4. Installing the Unit in Heavy Snow Areas
In locations with strong wind, snow-proof ducting should be fitted and direct exposure to the wind should be avoided as much as possible.
■ Countermeasures against snow and wind
In regions with snow and strong wind, the following problems may occur when the outdoor unit is not provided with a platform and snow-proof ducting:
a)The outdoor fan may not run and damage to the unit may occur.
b)There may be no air flow.
c)The tubing may freeze and burst.
d)The condenser pressure may drop because of strong wind, and the indoor unit may freeze.
2-5. Precautions for Installation in Heavy Snow Areas
(1)The platform should be higher than the max. snow depth. (Fig. 2-6)
(2)The 2 anchoring feet of the outdoor unit should be used for the platform, and the platform should be installed beneath the air intake side of outdoor unit.
(3)The platform foundation must be firm and the unit must be secured with anchor bolts.
(4)In case of installation on a roof subject to strong wind, countermeasures must be taken to prevent the unit from being blown over.

3-3. Placing the Unit Inside the Ceiling
(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) The size of the opening for the indoor unit can be confirmed by attaching the full-scale installation diagram beneath the unit. (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 each suspension bolt must be appropriate for a distance between the bottom of the bolt and the bottom of the ceiling of 19/32 in. or more as shown in Fig. 3-4.
(3)Thread the 2 hexagonal nuts (field supply) and washers onto the 4 suspension bolts as shown in Fig. 3-5.
Use 2 sets of nuts and washers (upper and lower), so that the unit will not fall off the suspension lugs.
(4)Remove the protective cardboard used to protect the fan parts during transport.
(5)Adjust the distance between the unit and surface of the ceiling. (1-7/8 in.) (Fig. 3-4)

3-4. Installing the Drain Piping
(1)Prepare standard hard PVC pipe for the drain and use the supplied drain hose and hose band to prevent water leaks.
XThe PVC pipe must be purchased separately. The transparent part allows you to check drainage. (Fig. 3-6)
Tighten the hose clamps so CAUTION their locking nuts face upward.
(Fig. 3-6)
(2)After checking the drainage, wrap the supplied packing and drain pipe insulator around the pipe. (Fig. 3-7)
NOTE
Ensure the drain pipe has a downward gradient (1/100 or more) and that there are no water traps.
CAUTION
●Do not install an air bleeder tube, as this may cause water to spray from the drain tube outlet. (Fig. 3-8)
●If it is necessary to increase the height of the drain pipe, the section directly after the connection port can be raised a maximum of 19-11/16 in. Do not raise it any higher than 19-11/16 in., as this could result in water leaks. (Fig. 3-9)
●Do not install the pipe with an upward gradient from the connection port. This will cause drain water to flow backwards and leak when the unit is stopped. (Fig. 3-10)
●Do not apply force to the piping on the unit side when connecting the drain pipe. The pipe should not be allowed to hang unsupported from its connection to the unit. Fasten the pipe to a wall, frame, or other support as close to the unit as possible. (Fig. 3-11)
●Provide insulation for any drain pipe that is run indoors.

3-5. Checking the Drainage
After wiring and piping are completed, use the following procedure to check that the water will drain smoothly. For this, prepare a bucket and wiping cloth to catch and wipe up spilled water.
Do not supply power to the WARNING unit until the tubing and
wiring to the outdoor unit are completed.
(1)Take off the tube cover and through the opening, slowly pour about 43 oz. of water into the drain pan to check drainage.
(2)Do Test Run to check the drainage after completing installation. When performing Test Run, be sure to observe the Test Run procedure.
Refer to page 105.
Be careful since the fan will CAUTION start turning when checking
the drainage.
(3)After drain checking is finished, return the Operation Selector switch to the RUN position (ON position ) and remount the tube cover.
To mount the tube cover, use WARNING 5/16" (4 × 8 mm) tapping
screws. Do not use long screws as they may puncture the drain pan and cause water leakage.
