Installation
Cautio Caution
Sharp edges and coil surfaces are potential injury hazard. Avoid from contact with them.
(1) Installation of Outdoor Unit
Preliminary Site Survey
• Electrical supply and installation is to conform to local authority's (e.g. National Electrical Board) codes
and regulations.
• Voltage supply fluctuation must not exceed ± 10% of rated voltage. Electricity supply lines must be
independent of welding transformer which can cause high supply fluctuations.
• Ensure that the location is convenient for wiring, piping and drainage
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.
