Level Hole Saw Core bits Hammer Drill Torque wrench Adjustable wrench Flat head screwdriver Philips head screwdriver Wire stripper Measuring tape Ratchet set Flaring tools Tube cutter Correct size copper tubing Correct size drain pipe Sleeve and bush Vinyl tape Saddle & Clamps to support refrigerant piping 6.
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.
RECOMMENDED HEIGHT AND LENGTH (MAXIMUM PIPING LENGTH & HEIGHT RECOMMENDED) If the refrigerant piping is longer than the recommended length, or if the height difference between the indoor and outdoor unit is greater than recommended, the capacity will drop and the compressor could malfunction. Select an installation location that is within the recommended parameters.
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 markingoff 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.
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.
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 condense on the surface of the pipes, resulting in heat loss. Narrow Pipe Wide Pipe Common insulation Separate insulation is essential PRECAUTIONS WHEN BENDING PIPES ! ! ! The air conditioner's performance will suffer if the piping is crushed.
(c) PRECAUTIONS WHEN CONNECTING PIPES: Connections will go more smoothly if the 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. Then tighten to the specified torque using a wrench. In particular, when tightening 1/4" diameter flare nuts, use the specified torque wrench First, 2 or 3 turns by hand Nipple Flair nut Fix in place.
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.
DRAIN PIPE CONNECTION The fan coil is equipped with a drain hose. It is tied together with the refrigerant piping. During installation, it is important to observe the following instructions to prevent water overflowing from the drain pan. ! Insure that the indoor unit is level and not tilted forwards or backwards. ! Insure that the drain hose does not rise above the drain pan. It should be sloping towards the hole. ! Route the drain hose through the same hole as the refrigerant pipes.
Outdoor unit Holder for Control board connecting cable cover ELECTRICAL WIRING to power supply LOCATION OF TERMINAL BLOCK: The terminal block on the indoor unit is located next to the PCB. Cable access is through the back of the unit. For the condensing unit, the terminal block is located behind the control panel. Holder to power supply cord connecting cable WIRING CONNECTION: ! ! ! ! ! ! ! All wiring and grounding must comply with the local Electric Codes.
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.
AUXILIARY CONTROL Figure below illustrates the auxiliary control on the fan coil. This can be used to operate / control the air conditioner when the remote controller is not available or lost. Test Use to operate the air conditioner under "COOL" mode. All other functions will not be effective. The air conditioner will automatically stop operating after 30 minutes. This is to test if the air conditioner is in working condition.
REMOTE CONTROL OPERATION CONTROLS AND INDICATORS Figure below illustrates the various controls and indicators of the LCD wireless remote control.
MODEL: AMW 45, 60
OPERATING INSTRUCTIONS Before operating the unit for the first time, it is necessary to install the batteries in the remote controller. ! Batteries are located at the back of the remote controller (Model AMW25, 30) and at the front of the remote controller (Model AMW45, 60).
MODEL: AMW 45, 60 ! ! ! ! ! ! ! Start air conditioner. Point the remote controller at the fan coil and press "ON/OFF" button. Select operation mode. Press "Mode" button to select any of the following modes: "Cool", "Dry" or "Vent". Temperature setting. Press "+" or "-" button to set desired temperature. Select fan speed. Press "Fan control" button to select desired fan speed. Select airflow direction. Press "Louver control" button to set position of horizontal vane or set it to auto swing. Set Timer.
CARE AND MAINTENANCE ! The air conditioner requires proper care and maintenance for efficient operation. A periodic inspection and cleaning may be available from your dealer or distributor. Be sure to ask about this service at the time of installation. The user can also perform some of the care and maintenance. Please follow these instructions. ! Be sure to disconnect the power supply before undertaking any inspection. ! Open the RETURN AIR GRILLE and remove the air filters.
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.
