10.3.5. 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
2
flexible cord, type designation H05 RN-F or heavier cord.
3. Secure the cable onto the control board with the holder
(clamper).
4. Confirm the SV Switch at AUTO position. (CU-MC145KE,
CU-3MC205KE)
5. Attach the control board cover back to the original position
with the screw.
10.3.6. 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.
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.
