• When working on the equipment, observe precautions in the literature and on tags, stickers, and labels attached to the equipment.

• Follow all safety codes. Wear safety glasses and work gloves. Keep quenching cloth and fire extinguisher nearby when brazing. Use care in handling, rigging, and setting bulky equipment.
  Read these instructions thoroughly and follow all warnings or cautions included in the literature and attached to the unit. Consult local building codes and National Electrical Code (NEC) for special requirements. Recognize safety information.

• This is a safety symbol

• When you see this symbol on the unit and in instructions or manuals, be alert to the potential for personal injury. Understand these signal words: DANGER, WARNING, and CAUTION. These words are used with the safety alert symbol. DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies hazards that could result in personal injury or death. CAUTION is used to identify unsafe practices which may result in minor personal injury or product and property damage. NOTE is used to highlight suggestions that will result in enhanced installation, reliability, or operation.

WARNING

ELECTRICAL OPERATION HAZARD

• Failure to follow this warning could result in personal injury or death.
• Before installing, modifying, or servicing the system, the main electrical disconnect switch must be in the OFF position. There may be more than 1 disconnect switch.

EXPLOSION HAZARD

• Failure to follow this warning could result in death, serious personal injury, and/or property damage.
• Never use air or gases containing oxygen for leak testing or operating refrigerant compressors. Pressurized mixtures of air or gases containing oxygen can lead to an explosion.

CAUTION

EQUIPMENT DAMAGE HAZARD

• Failure to follow this caution may result in equipment damage or improper operation.
• Do not bury more than 36 in. (914 mm) of refrigerant pipe in the ground. If any section of pipe is buried, there must be a 6 in. (152 mm) vertical rise to the valve connections on the outdoor units. If more than the recommended length is buried, the refrigerant may migrate to the cooler buried section during extended periods of a system shutdown. This causes refrigerant slugging and could possibly damage the compressor during the start-up process.

PARTS LIST

• If the outdoor unit is higher than the indoor unit, prevent rain from flowing into the indoor unit along the connection pipe by making a downward arc in the connection pipe before it enters the wall to the indoor This ensures that rain drips from the connection pipe before it enters the wall.

CLEARANCES – INDOOR

INSTALLATION TIPS

Ideal installation locations include:

Indoor Unit

• A location where there are no obstacles near the inlet and outlet area.
•  A location that can bear the weight of an indoor unit.
•  Do not install indoor units near a direct source of heat such as direct sunlight or a heating appliance.
•  A location that provides appropriate clearances.

Indoor Unit Installation

Prior to Installation

Before installing the indoor unit, ensure compatibility with the outdoor unit using the product data as a reference.

Select the Installation Location

Before installing the indoor unit, choose an appropriate location. The following are standards that should help you choose an appropriate location for the unit. Proper installation locations must meet the following standards:

• Good air circulation
•  Convenient drainage
• Noise from the unit will not disturb others
• Firm and solid—the location will not vibrate
• A site strong enough to support the weight of the unit
• A location at least 3.28 ft. (1m) from all other electrical devices (e.g., TV, radio, computer)
• DO NOT install the unit in the following locations:
• Near any source of heat, steam, or combustible gas
• Near flammable items such as curtains or clothing
• Near any obstacle that might block air circulation
• Near the doorway
• In a location subject to direct sunlight

Wall Holes: If there is no fixed refrigerant piping. While choosing a location, you should leave ample room for a wall hole (refer to the Drill wall hole for connective piping step) for the signal cable and refrigerant piping that connect the indoor and outdoor units. The default position for all piping is the right side of the indoor unit (while facing the unit). However, the unit can accommodate piping to both the left and right.

Attach the Mounting Plate to the Wall

• Carefully remove the mounting plate, which is attached to the back of the indoor unit.
• The mounting plate should be located horizontally and level on the wall. All minimum spacings (see Fig. 7) should be maintained.
• If the wall blocks, brick, concrete, or similar material, drill 0.2” (5mm,) diameter holes and insert anchors for the appropriate mounting screws.
• Attach the mounting plate to the wall.

Mounting Plate Dimensions

Different model sizes have different mounting plates. Ensure there’s enough room to mount the indoor unit.
The following measurements can be located on these figures

• Width of the mounting plate
•  Height of mounting plate
• Width of the indoor unit relative to the plate
• Height of indoor unit relative to the plate
• The recommended position of wall hole (both to the left and right of mounting plate)
• Relative distances between screw holes.

Correct orientation of Mounting Plate

DRILL HOLE IN WALL FOR THE INTERCONNECTING PIPING, DRAIN, AND WIRING

Refrigerant Line Routing

• The refrigerant lines may be routed in any of the four directions
• For maximum serviceability, it is recommended to have refrigerant line flare connections and the drain connections on the outside of the wall that the fan coil can be mounted on.

If piping is going through the back:

• Determine the pipe hole position using the mounting plate as a  template. Drill pipe hole diameter per values given in Figures 3−6. The outside pipe hole is 1/2−in. (13 mm) min. lower than the inside pipe hole, so it slants slightly downward.

Prepare the Refrigerant Piping

The refrigerant piping is inside an insulating sleeve attached to the back of the unit. You must prepare the piping before passing it through the hole in the wall. (Piping Angle) Refrigerant piping can exit the indoor unit from four different angles.

1. Left−hand side
2. Left rear
3. Right−hand side
4. Right rear

Prepare the Refrigerant Piping Dissemble the louver.

Dissemble the Louver

Open and fix the position of the panel. First, unscrew the two screws (see Fig. 15), then open the panel, and fix the position of the panel by the latch.

Hook Indoor Unit to Mounting Plate

Use the holder in the mounting plate to prop up the unit, allowing you enough space to connect the refrigerant piping, signal cable, and drain hose.

• Use Holder to Prop up the unit
• Connect the drain hose and refrigerant piping.
• Keep the pipe connection point exposed to perform the leak test.
• After the leak test, wrap the connection point with insulation tape.
• Remove the bracket or wedge that is propping with insulation tape.
• Using even pressure, push down on the bottom half of the unit. Keep pushing down until the unit snaps onto the hooks along the bottom of the mounting plate.

Panel Position

If there is no refrigerant piping embedded in the wall, perform the following steps:

• Based on the position of the wall hole relative to the mounting plate, choose the side from which the piping will exit the unit.
• If the wall hole is behind the unit, keep the knock−out panel in place. If the wall hole is to the side of the indoor unit, remove the plastic knock−out panel from that side of the unit (see Fig. 17). This creates a slot through which your piping can exit the unit. Use needle-nose pliers if the plastic panel is too difficult to remove by hand.

Knock Out Panel

• Use scissors to cut down the length of the insulating sleeve to reveal about 1.57in. (40mm) of the refrigerant piping. This serves two purposes:
• To facilitate the refrigerant piping connection process
• To facilitate Gas Leak Checks and enable you to check for
• Connect the indoor unit’s refrigerant piping to the connective piping that joins the indoor and outdoor units.
• Based on the position of the wall hole relative to the mounting plate, determine the necessary angle of your piping.
• Grip the refrigerant piping at the base of the bend.
• Slowly, with even pressure, bend the piping towards the hole. Do not dent or damage the piping during the process.
