Notice To Owner/Installer This unit is designed for installation by an experienced person. It is legal for a homeowner

to install it, however we highly recommend using a licensed HVAC technician for

installation. There is high-voltage DC power used inside and outside of the unit.

There are capacitors inside the unit that may contain dangerous levels of power even after the unit has been disconnected from its power source. The power must be

disconnected and all of the capacitors must be discharged before servicing the system.

Legal Information About Self-Installing R-410A Air Conditioners Can a homeowner install this system?

Yes, a homeowner with a vacuum pump, proper training, and equipment can install this unit. Unless you are experienced with installing air conditioners we recommend you hire a

professional installer. The person who installs the system must do all work in compliance

with local building and electrical codes.

Are there any restrictions on the purchase of R410A refrigerants? R-410A is not an ozone-depleting substance. At this time the purchase of R-410A

refrigerant is not restricted in the US. There is no technician certification requirement for those that purchase HFC refrigerants, such as R-410a or R-134a. If you are not licensed, some local HVAC supply companies may refuse to sell you R410A based on a misunderstanding of the law, or because they wish to discourage homeowners from working on their own systems.

Are there any restrictions on the use of R410A refrigerants?

Yes, it is illegal to knowingly vent or release these refrigerants. The venting prohibition applies to R410A, and all other HFC refrigerants, just as it does for ozone-depleting refrigerants like R-22.

Is EPA technician certification required to service R410A systems? No, at this time EPA technician certification is not required in order to service R-410a systems.

SELECT THE BEST LOCATION

Indoor unit

There should not be any heat source or steam near the unit. There should not be any obstacles blocking the air circulation. Choose a location where air flow is good. Choose a location where condensate drainage can be easily done and where noise prevention is taken into consideration. Do not install the unit near the en trance or exit of the room. Ensure the clearances indicated by arrows, from the wall, ceiling, fence or other obstacles. See figure 1. There should not be any direct sunlight on

the indoor unit. If unavoidable, sunlight prevention

should be taken into consideration.

Outdoor unit

If an awning is built over the unit to prevent direct sunlight or rain, be careful that heat radiation from the condenser is not obstructed. There should not be any animals or plants near the unit which could be affected by hot air discharged. Ensure the clearances indicated by arrows, from the wall, ceiling, fence or other obstacles. See figure 2

Do not place any obstacles on the unit that may interfere with the discharged air flow.

Placement of the outdoor unit

Anchor the outdoor unit with a bolt and nut 10 or 8 tightly and horizontally on a concrete or rigid mount. NOTE: Install the outdoor unit according to the dimension as indicated below: Outdoor Unit Dimensions (760 x 590 x 285) mm

FITTING THE INSTALLATION PLATE

NOTE: Fitting The Installation Plate

Ensure that the mounting wall is strong and solid enough to prevent vibration.

1. Fit the installation plate horizontally on structural parts of the wall with spaces around the installation plate. See figure 3

2. If the wall is made of brick, concrete or the like, drill eight (8) 5mm diameter holes in the wall and insert anchor clips for appropriate mounting screws.

3. Fit the installation plate on the wall with eight (8)

type A screws.

Fit the Installation Plate and drill holes in the wall according to the wall structure and corresponding mounting points on the installation plate. The installation plate is provided with the machine. (Dimensions are in mm unless otherwise stated) For correct orientation of Installation plate see figure 4.

DRILL A HOLE IN THE WALL

1. Determine left and right side hole positions according to the installation plate. The hole center is obtained by measuring the distance as shown in the diagram figure

2. Drill the piping plate hole with 65mm hole saw drill bit.

3. Drill the piping hole at either the right or the left side. The hole should be slightly slanted to the outdoor

side for condensate water drainage.

See figure 5 4 Always use conduit when drilling through metal grid, metal plate or the like.

CONNECTIVE PIPE AND DRAINAGE INSTALLATION

DRAINAGE

1. Run the drain hose sloping downward. Do not install the drain hose as illustrated in figure 6

2. When connecting the extension drain hose, seal the connecting part of extension drain hose with water proof tape, do not let the drain hose slack.

Connect the indoor unit first, then the outdoor unit.

CONNECTIVE PIPE INSTALLATION

1. For the left- hand and right-hand piping, remove the pipe cover from the side panel.

2. For the rear-right-hand and rear-left –hand piping, install the piping as shown in figure 7.

3. Bundle the tubing, connecting cable, and drain hose securely with tape, evenly, as shown in figure 8, on the right. Because the condensed water from rear of the indoor unit is gathered in a reservoir and is piped out of room, do not put anything else in the reservoir.

CAUTION Connect the indoor unit first, then the outdoor unit. Do not allow the piping to hang out from the back of the indoor unit.

Be careful not to let the drain hose slack. Use insulation such as Armaflex to insulate the line set. Be sure that the drain hose is located at the lowest side of the bundle. See figure 8.

If drain hose is located at the upper side it can cause drain tray to overflow inside the unit. Never intercross or wind the power wire with any other wiring. Run the drain hose sloped downward to drain out the condensed water smoothly.
