5. Refrigerant piping work
5.1. Refrigerant pipe (Fig. 5-1)
Piping preparation
• Refrigerant pipes of 3, 5, 7, 10 and 15 m are available as optional items.
(1) Table below shows the specifications of pipes commercially available.
(2) Ensure that the 2 refrigerant pipes are well insulated to prevent condensation.
(3) Refrigerant pipe bending radius must be 100 mm or more.
Caution:
Using careful insulation of specified thickness. Excessive thickness prevents
storage behind the indoor unit and smaller thickness causes dew drippage.

5.2. Flaring work
• Main cause of gas leakage is defect in flaring work.
Carry out correct flaring work in the following procedure.
5.2.1. Pipe cutting (Fig. 5-2)
• Using a pipe cutter cut the copper tube correctly.
5.2.2. Burrs removal (Fig. 5-3)
• Completely remove all burrs from the cut cross section of pipe/tube.
• Put the end of the copper tube/pipe to downward direction as you remove burrs in
order to avoid burrs drop in the tubing.
5.2.3. Putting nut on (Fig. 5-4)
• Remove flare nuts attached to indoor and outdoor unit, then put them on pipe/tube
having completed burr removal.
(not possible to put them on after flaring work)
5.2.4. Flaring work (Fig. 5-5)
• Carry out flaring work using flaring tool as shown at the right.

Firmly hold copper tube in a die in the dimension shown in the table at above.
5.2.5. Check (Fig. 5-6)
• Compare the flared work with a figure in right side hand.
• If flare is noted to be defective, cut off the flared section and do flaring work again.

- Making a duct flange prepared locally the shape of duct flange shown left is recommended installation of duct flange cut out the cutout hole do not knock it out install a duct flange to the cutout hole of the indoor unit with three 4 10 tapping screws which should be prepared locally installation of duct should be prepared locally prepare a duct of which inner diameter fits into the outer diameter of the duct flange in case that the environment above the ceiling is high temperature and high humid ity wrap the duct in a heat insulate to avoid causing dew drop on the wall 4
- Suspend the main unit as shown in the diagram 1 in advance set the parts onto the suspension bolts in the order of the washers with insulation washers without insulation and nuts double fit the washer with cushion so that the insulation faces downward in case of using upper washers to suspend the main unit the lower washers with insulation and nuts double are to be set later 2 lift the unit to the proper height of the suspension bolts to insert the mounting plate between washers and then fasten it securely 3 when the main unit can not be aligned against the mounting hole on the ceiling it is adjustable owing to a slot provided on the mounting plate fig 4 6 make sure that step a is performed within 27 32 mm damage could result by failing to adhere to this range 4
- Suspension structure give site of suspension strong structure fig 4 4 4
- The ceiling work differs according to the construction of the building building con structors and interior decorators should be consulted for details 1 extent of ceiling removal the ceiling must be kept completely horizontal and the ceiling foundation framework wooden slats and slat holders must be reinforced in order to protect the ceiling from vibration 2 cut and remove the ceiling foundation 3 reinforce the ends of the ceiling foundation where it has been cut and add ceiling foundation for securing the ends of the ceiling board 4 when installing the unit on a slanting ceiling interlock a pillow between the ceiling and the grille and set so that the unit is installed horizontally 1 wooden structures use tie beams single story houses or second floor beams two story houses as reinforcing members wooden beams for suspending air conditioners must be sturdy and their sides must be at least 6 cm long if the beams are separated by not more than 90 cm and their sides must be at least 9 cm lo 4
- Unit suspension procedures fig 4 5 4
- Using the gauge attached to the grille ensure that the bottom of the main unit is properly aligned with the opening of the ceiling be sure to confirm this otherwise condensation may form and drip due to air leakage etc confirm that the main unit is horizontally levelled using a level or a vinyl tube filled with water after checking the position of the main unit tighten the nuts of the suspension bolts securely to fasten the main unit the installation template can be used as a protective sheet to prevent dust from entering the main unit when the grilles are left unattached for a while or when the ceiling materials are to be lined after installation of the unit is finished as for the details of fitting refer to the instructions given on the installation template 4

- Function selection of remote controller if two remote controllers are connected set one to main and the other to sub for setting procedures refer to function selection of remote controller in the operation manual for the indoor unit 8
- Installation area area in which the remote controller is not exposed to direct sunshine area in which there is no nearby heating source area in which the remote controller is not exposed to cold or hot winds area in which the remote controller can be operated easily area in which the remote controller is beyond the reach of children 2 installation method 1 attach the remote controller holder to the desired location using two tapping screws 2 place the lower end of the controller into the holder the signal can travel up to approximately 7 meters in a straight line within 45 degrees to both right and left of the center line of the receiver in addition the signal may not be received if there is interference of light of fluores cent lights or strong sunlight 8
- Installing procedures 1 select an installing position for the remote controller fig 7 6 the temperature sensors are located on both remote controller and indoor unit s procure the following parts locally two piece switch box thin copper conduit tube lock nuts and bushings 8
- Perform wiring as shown in the diagram to the lower left procure the cable locally fig 7 4 make sure to use cables of the correct polarity only 8
