SELECTION OF LOCATION Select a convenient location where: INDOOR UNIT ! The cool air can reach every corner of the area to be cooled. ! The unit is away from any direct heat source ! Easy and short routing of the refrigerant and drain pipes to the exterior. ! There are no flammable gas, alkaline or acid present in the air. ! Air circulation is not obstructed, preventing good air circulation. ! The structure where the unit is installed should be strong enough to support the weight of the u

MOUNTING INSTALLATION PLATE: The fan coil can be installed using any of the four methods described below. Determine which is the most suitable method. Position the installation plate on the wall making sure that it is parallel to the ground. This can be done by aligning the marking- off line with a thread and weight as shown in figure on the right. This is to ensure that the condensate water does not overflow from the drain pan. Mount the installation plate with the 4 screws provided.

INSTALLATION OF FAN COIL: The extended liquid and suction pipes and drain hose are hidden inside a slot at the back of the fan coil. This allows the hole on the wall to be either on the right or left side of the fan coil. RIGHT SIDE HOLE POSITION: The piping and drain hose are routed straight through the hole. LEFT SIDE HOLE POSITION: The piping and drain hose run from the right side to the left side of the unit, hidden in the slot at the back of the unit before routing through the hole

REFRIGERATION PIPING & DRAINAGE PREPARATION OF PIPING Fan coil and side discharge condensing units are equipped with flare connections. Improper flaring and brazing may cause refrigerant to leak out of the system. Follow these instructions carefully in preparing the refrigerant piping. ! Ensure that all piping is of the correct size. ! Measure the distance between the indoor and outdoor units' refrigerant connections, together with all the curves necessary. Add a few inches as slack. ! Lay

PIPING INSULATION Insulation Liquid and suction lines must be insulated separately. In a cooling only type air conditioner, both pipes become cold during operation. This can cause moisture to Narrow Pipe Wide Pipe condense on the surface of the pipes, Common insulation resulting in heat loss. Separate insulation is essential PRECAUTIONS WHEN BENDING PIPES ! The air conditioner's performance will suffer if the piping is crushed. ! Bend pipes using the pads of your thumbs to prevent the

(c) PRECAUTIONS WHEN CONNECTING PIPES: Connections will go more smoothly if the First, 2 or 3 turns by hand large pipe is connected first, followed by the small pipe. Hold the nipple and the flare nut straight and lightly turn the nut two or three turns by hand to ensure that the threads are aligned. Nipple Flair nut Then tighten to the specified torque using a wrench. In particular, when tightening 1/4" diameter flare nuts, use the specified torque wrench Always look at arrow on

AIR PURGING This procedure is used to remove air from inside the piping connecting the indoor and outdoor units, as well as the air inside the indoor unit. If air purging is not carried out, air will beocme mixed into the refrigerant cycle, causing the pressure to rise to abnormally high levels, increasing power consumption and reducing the capacity of the unit. Also, moisture in the air can cause insulation failure in the compressor motor and deterioration of the refrigerant oil, resultin

OPERATING INSTRUCTIONS OPERATING TIPS: Observe the following points for economical and safe operation: ! Keep the room temperature at a comfortable level. Too much cooling is unhealthy and results in excessive consumption of electricity. A temperature setting of 75°F (24°C) is usually sufficient during the day. During the night, set the temperature a few degrees higher as the body temperature is reduced when a person is asleep. ! Adjust the vertical and horizontal louvers to provide unifo

TROUBLE SHOOTING The following are normal and should not be treated as defects. ! Hissing sound, like flow of water from the unit. This is the sound of the refrigerant at the expansion device, which can be heard from time to time depending on the indoor and outdoor ambient conditions. ! The unit does not cool for a few minutes after it restarts. This is because a time delay mechanism built into the unit prevents the compressor from starting for a few minutes. This is to protect the compre
