Installation
Caution
Sharp edges and coil surface are potential injury hazard. Avoid from contact with them.
(1) INSTALLATION OF INDOOR UNIT
Preliminary Site Survey
• Electrical supply and installation shall conform to the local authority (eg. National Electrical Board).
• Voltage supply fluctuation must not exceed ±10% of the rated voltage. Electricity supply lines must be
independent of welding transformers which can cause high supply fluctuation.
• Ensure that the installation location is convenient for wiring and piping.
Standard Mounting
Ensure that the overhead supports are strong enough to hold the weight of the unit. Position the hanger rods
(wall mounting bracket for floor standing), and check for its alignment with the unit as shown in Figure A.
Also, check that the hangers are secured and the base of the fan coil unit is leveled in both horizontal
directions, taking into account the gradient for drainage flow as recommended in Figure B.
