Selecting the Best location / General Mounting
Selecting the best location
Do’s
•
Place the unit where air circulation will not be blocked.
•
Place the unit where drainage can be obtained easily.
•
Place the unit where noise prevention is taken into consideration.
•
Ensure there is sufficient space from the ceiling and floor.
•
Ensure there is sufficient maintenance space.
•
Locate the indoor unit in a location where it can be easily connected
to the outdoor unit / heat recovery unit.
don’ts
• Avoid installing the unit near high-frequency generators.
• Do not install the unit near a doorway.
• The unit should not be installed near a heat or steam source, or
where considerable amounts of oil, iron powder, or flour are used.
(These materials may generate condensate, cause a reduction in
heat exchanger efficiency, or the drain to malfunction. If this is a
potential problem, install a ventilation fan large enough to vent out
these materials.)
Installing in an Area Exposed to Unconditioned Air
In some installation applications, areas (floors, walls) in some rooms may be exposed to unconditioned air (room may be above or next to an
unheated garage or storeroom). To countermeasure:
•
Verify that carpet is or will be installed (carpet may increase the temperature by three [3] degrees).
•
Add insulation between the floor joists.
•
Install radiant heat or another type of heating system to the floor.
general Mounting
Wall-mounted indoor units have several options on how the piping and wiring can
be routed (see figure at right). Whichever way the piping and wiring are routed out
of the indoor units, the mounting wall on which the indoor unit is installed should
be strong and solid enough to protect it from vibration.
•
Mount the installation plate on the wall using four (4) Type “A” screws. If mount-
ing the unit on concrete, consider using anchor bolts.
•
Always mount the installation plate horizontally. Measure the wall and mark the
centerline using thread and a level.
If the unit is installed near a body of water, the installation parts are at risk of corroding. Appropriate anti-corrosion methods should be
taken for the unit and all installation parts.

Figure 35: Choice of Piping / Wiring Routes.
The unit should not be installed where sulfuric acid and flammable
or corrosive gases are generated, vented into, or stored. There is
risk of fire, explosion, and physical injury or death.
the unit may be damaged, may malfunction, and / or will not operate as designed if installed in any of the conditions listed.
