Caution:
Be very careful when carrying/moving the product.
- When installing the heat source unit, suspend the unit at the specified location
of the unit base. Stabilize as necessary so that it does not move to the side
and support it at 4 points. If the unit is installed or suspended with 3-point
support, the unit may become unstable and fall.
Warning:
•
Be sure to install unit in a place strong enough to withstand its weight.
Any lack of strength may cause unit to fall down, resulting in a
personal injury.
•
Have installation work in order to protect against strong winds and
earthquakes.
Any installation deficiency may cause unit to fall down, resulting in a
personal injury.
When building the foundation, give full attention to the floor strength, drain water
disposal <during operation, drain water flows out of the unit>, and piping and
wiring routes.
Precautions when routing the pipes and wires below the unit (Without
detachable leg)
When routing the pipes and wires below the unit, be sure that the foundation and
base work do not block the base through-holes. Also make sure the foundation
is at least 100 mm high so that the piping can pass under the unit.
