Installation of MCM unit
Preliminary site survey
ó Electrical supply and installation shall conform to the local authority (e.g. National Electrical Board).
ó Voltage supply fl uctuation must not exceed ± 10% of the rated voltage. Electricity supply lines must be independent
of welding transformers which can cause high supply fl uctuation.
ó Ensure that the installation location is convenient for wiring and piping.
Standard Mounting

mounting bracket for fl oor 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 fan coil unit is leveled in both horizontal directions, taking into account the
gradient for drainage fl ow as recommended in Figure A.
