10.6.5. CONNECT THE CABLE TO THE OUTDOOR UNIT
1. Remove the control board cover from the unit by loosening the screw.
2. Connecting cable between indoor unit and outdoor unit shall be approved polychloroprene sheathed 3 × 1.5 mm
type designation 245 IEC 57 or heavier cord.
3. Secure the cable onto the control board with the holder (clamper).
4. Attach the control board cover back to the original position with the screw.
10.6.6. PIPE INSULATION
1. Please carry out insulation at pipe connection portion as mentioned in Indoor/Outdoor Unit Installation Diagram. Please wrap
the insulated piping end to prevent water from going inside the piping.
2. If drain hose or connecting piping is in the room (where dew may form), please increase the insulation by using POLY-E FOAM
with thickness 6 mm or above.
DISPOSAL OF OUTDOOR UNIT DRAIN WATER
• If the drain elbow is used, the unit should be placed on a
stand which is taller than 3cm.
• If the unit is used in an area where temperature falls below
0° C for 2 or 3 days in succession, it is recommended not to
use a drain elbow, for the drain water freezes and the fan
will not rotate.
CHECK THE DRAINAGE
• Open front panel and remove air filters.
(Drainage checking can be carried out without removing the
front grille.)
• Pour a glass of water into the drain tray-styrofoam.
• Ensure that water flows out from drain hose of the indoor
unit.
EVALUATION OF THE PERFORMANCE
• Operate the unit at cooling operation mode for fifteen
minutes or more.
• Measure the temperature of the intake and discharge air.
• Ensure the difference between the intake temperature and
the discharge is more than 8°C.
