Ensure that the overhead supports are strong enough to hold the
unit's weight. Position hanger rods and check for alignment with
the unit. Check that hangers are secure and that the base of fan-coil
unit is level in the two horizontal directions, taking into account
the gradient recommended for drainage flow as shown.
Check the gradient recommended for drainage flow as follow.

Location For Installation
Install the outdoor unit in such way that air distributed by the
outdoor unit cannot be drawn in again (as in the case of short
circuit of discharge air). Allow sufficient space for maintenance
around the unit.
Ensure that there are no obstruction of air flow into or out of the
unit. Remove obstacles which block air intake or discharge.
The location must be well ventilated, so that the unit can draw and distribute plenty of air.
A place capable of bearing the weight of the outdoor unit and isolating noise and vibration.
A place protected from direct sunlight. Otherwise use an awning for protection, if necessary.
A place where smooth drainage of rain water and water formed by defrosting is acceptable.
A place where the unit will not be buried in snow.
A place where air outlet port is not exposed to strong wind.
A place where the air discharge and operating sound level will not annoy the neighbours.
The location must not be susceptible to dust or oil mist.
If the condensing unit is operated in an atmosphere containing oils (including machine oils), salt (coastal area),
sulfide gas (near hot spring, oil refinery plant), such substances may lead to failure of the unit.
Installation Clearance
Outdoor unit must be installed such that there is no short circuit of the discharge air or obstruction to smooth air flow.

When two or more outdoor units are installed in a location, they
must be positioned such that one unit will not be taking the
discharge air from another.
This also applies when two or more units are installed one above
the other. The units must all face the same direction, or opposite
direction (back to back), such that air short circuit does not occur.
