should be taken to ensure the unit's correct operation. When the unit is
H[SHFWHGWRRSHUDWHLQFRROLQJPRGHLQFRQGLWLRQVXQGHU&>)@LQ
snowy areas, in environments subject to strong winds or rain, install air inlet
and outlet ducting as shown in [Fig. 8.1.2].
Note:
1. Height of frame base for snow damage prevention (H) shall be twice as high
as expected snowfall. Width of frame base shall not exceed that of the unit.
The frame base shall be made of angle steel, etc., and designed so that
snow and wind slip through the structure. (If frame base is too wide, snow
will be accumulated on it.)
2. Install unit so that wind will not directly lash against openings of inlet and
outlet ducts.

4. When the unit is used in a cold region and the heating operation is
continuously performed for a long time when the outside air temperature
is below freezing, install a heater to the unit base or take other appropriate
measures to prevent water from freezing on the base.
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.

Precautions when routing the pipes and wires below the unit
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 [3-15/16 in] high so that the piping can pass under the unit.
