11.1 Attached Accessories
11.2 Indoor Unit
11.2.1 Selecting the Location for the Indoor Unit Provide a check port on the piping side ceiling for repair and maintenance. Install the indoor unit once the following conditions are satisfied and after receiving the customer approval.
1 The indoor unit must be within a maintenance space. 2 The indoor unit must be free from any obstacles in path of the air inlet and outlet, and must allow spreading
of air throughout the room. 3 Mount with the lowest moving parts at least 8 ft (2.4 m) above floor or grade level.
* If the height from the floor to ceiling exceeds three meters, air flow distribution deteriorates and the effect is
decreased.
4 The installation position must be able to support a load four times the indoor unit weight. 5 The indoor unit must be away from heat and steam sources, but avoid installing it near an entrance.
Installation parts you should purchase ( )

6 The indoor unit must allow easy draining. 7 The indoor unit must allow easy connection to the outdoor unit. 8 Place the indoor unit according to the height from the ceiling shown in the illustration below. 9 The indoor unit must be from at least 9.8 ft (3 m) away from any noise-generating equipment. The electrical
wiring must be shielded with a steel conduit. 10 If the power supply is subject to noise generation, add a suppressor. 11 Do not install the indoor unit in a laundry. Electric shocks may result.
Note Thoroughly study the following installation locations
1 In such places as restaurants and kitchens, considerable amount of oil steam and flour adhere to the turbo
fan, the fin of the heat exchanger and the drain pump, resulting in heat exchange reduction, spraying, dispersing of water drops, drain pump malfunction, etc. In these cases, take the following actions: o Make sure that the ventilation fan for smoke-collecting hood on a cooking table has sufficient capacity so
that it draws oily steam which should not flow into the suction of the air conditioner. o Make enough distance from the cooking room to install the air conditioner in such place where it may not
suck in oily steam.
2 Avoid installing the air conditioner in such circumstances where cutting oil mist or iron powder exist especially in factories, etc.
3 Avoid places where inflammable gas is generated, flows-in, contaminated, or leaked.
4 Avoid places where sulphurous acid gas or corrosive gas can be generated.
5 Avoid places near high frequency generators.

POSITIONS OF AIR CONDITIONER BODY AND CEILING SURFACE
11.2.3 Refrigerant Piping Refrigerant is charged to the outdoor unit. For details, see the manual for installation work of outdoor unit. (Additional charging, etc.)
1 Brazing for piping. a. Execute brazing before tightening the flare
nut. b. Brazing must be executed while blowing
nitrogen gas. (This prevents generation of oxidized scale in copper pipe.)
2 When there is a lot of brazings for long piping, install a strainer midway of the piping. (The strainer is locally supplied.)
3 Use clean copper pipe with inner wall surface free from mist and dust. Blow nitrogen gas or air to blow off dust in the pipe before connection.
4 Form the piping according to its routing. Avoid bending and bending back the same piping point more than three times. (This will result in hardening of the pipe).
5 After deforming the pipe, align centers of the union fitting of the indoor unit and the piping, and tighten them firmly with wrenches.
6 Connect pipe to the service valve or ball valve which is located below the outdoor unit.
7 After completed the piping connection, be sure to check if there is gas leakage in indoor and outdoor connection.
Vacuum drying
After completing the piping connection, execute vacuum drying for the connecting piping and the indoor unit. The vacuum drying must be carried out by using the service ports of both the liquid and gas side valves.
CAUTION Use two wrenches and tighten with regular torque.
Do not overtighten, overtightening may cause gas leakage.

11.2.4 Indoor Unit Drain Piping During drain piping connection, be careful not to exert extra force on the drain port at the indoor unit. The outside diameter of the drain connection at the indoor unit is 1-1/4" (32 mm).
Piping material: Polyvinyl chloride pipe VP-25 and pipe fittings.
Be sure to perform heat insulation on the drain piping. Heat insulation material: Polyethylene foam with thickness more than 5/16" (8 mm) (local supply).
Drain piping must have down-slope (1/50 to 1/100); be sure not to provide up-and-down slope to prevent reversal flow.
Be sure to check no air trap on drain hose and to ensure smooth water flow and no abnormal sound.
The height of drain may be possible up to 29-1/2"
(750 mm).
When drain set piping, install as shown in the figure below.
Drain Test The air conditioner uses a drain up motor to drain water. Use the following procedure to test the drain up motor operation.
Connect the main drain pipe to exterior and leave it provisionally until the test comes to an end. Feed water to the flexible drain hose and check the piping for leakage. Be sure to check the drain up motor for normal operating and noise when electric wiring is complete. When the test is complete, connect the flexible drain hose to the drain port. Pour about 600-700cc of water in the drain pan of the indoor unit. (Pour from the position specified in the drawing
by using a water supply bottle or other suitable tool.) Press the drain pump test run on PCB to start the drain motor, and verify water drainage.
(The drain motor will automatically stop after operating for about five minutes.)

11.2.5 Heat Insulation
Be sure to perform heat insulation on the drain, liquid and gas piping. Imperfection in heat insulation work leads to water leakage.
1 Use the heat insulation material for the refrigerant piping which has an excellent heat-resistance (over 248F (120C)).
2 Precautions in high humidity circumstance. 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 73.4F (23C)), water drops are liable to fall. In this case, add heat insulation material according to the following procedure: o Heat insulation material to be prepared Adiabatic glass wool with thickness 3/8" to 1 3/16" (10 to
20 mm). o Stick glass wool on all air conditioners that are located in ceiling atmosphere. o In addition to the normal heat insulation (thickness: more than 5/16" (8 mm) for refrigerant piping (gas
piping: thick piping) and drain piping, add a further of 3/8" (10 mm) to 1 3/16" (30 mm) thickness material.
Wall seal
When the outdoor unit is installed on a higher position than the indoor unit, install the trap so as not to instill rain water into the wall by transmitting in piping.
Stuff the space among piping, the electric wire, and- the drain hose with Putty and seal the penetration wall hole. Make sure that rain water do not instill into the wall.
Overlap with heat insulator for piping.

2 Fitting the decorative panel o Temporarily secure the fixing screws (3
pcs.) before fitting the decorative panel. (For temporarily securing the front grille.)
o Place decorative panel on the screws (3 pcs.) before fitting, move decorative panel as illustrated and tighten all the screws (4 pcs.).
Check before hand the height from the ceiling to the unit.
The front grille fitting direction is determined by the unit direction.
Only use the screws with the length of 1-3/8" (35 mm) which is provided, to fix the decorative panel.
Do not use other screw which is longer it may cause damage to the drain-pan and other components.
3 Fit the decorative panel and ceiling wall together and confirm no gap in between. Readjust indoor unit height, if there is a gap between ceiling wall and decorative panel.
4 Open the indoor control box cover by removing 2 pcs of screw.
5 Insert firmly the connector of cosmetic louver to indoor pcb CN-STM1, CN-STM2 and CN-DISP. Be caution not to clamp the cord in between control board and control board cover.
6 After complete, install back removed part follow reverse procedure.
Be sure to hook the air inlet grill string, to prevent grill from falling and causing injury from it.
