3. Installation of outdoor unit
3.5 Selection of the best location
This Multi F unit is suitable for installation in a residential and commercial environmental situation.
If installed near a household appliance it can cause electromagnetic interference.
The units should be installed in a location that meets the following requirements:
① A robust and strong base which can support the weight of the unit and will not degrade easily
② If an awning is built over the unit to prevent direct sunlight or rain exposure, make sure that the discharge air of the con-
denser is not restricted.
③ It is recommended that the outdoor unit should be fenced to avoid animals or plants being exposed in the direct path of
the discharged air .
④ Ensure proper spaces between the unit and its surrounding as given in the figure.
⑤ Ensure that the water shall not cause any damage by overflowing in case of water condensation
⑥ The noise, vibration and hot discharged air of the outdoor unit should not annoy the surrounding environment.
⑦ Ensure that there is no damage to the pipes in long run as it may cause the refrigerant leakage.
⑧ In case the outdoor may have heavy snow :
a. Make foundation at a suitable height.
b. Fit a suitable hood or a awning over the unit.
⑨ Rooftop Installations : If the outdoor unit is installed on a roof structure, be sure to level the unit. Ensure the roof structure
and anchoring method are adequate for the unit location. Consult local codes regarding rooftop mounting.

CAUTION
1. Actually the R410A refrigerant is not toxic, nonflammable and odor free. Any how if the refrigerant is leaked then its
concentration may exceed the allowable limit depending on the related space volume.
Due to this, it is necessary to take measures for the volume size against leakage.
2. Do not install unit in following locations.
• Locations where sulfurous acids or this kind of other corrosive gases might be help to corrode of copper piping and
soldered joints, and can cause refrigerant leakage.
• Locations such as kitchens or cuisine which contain a lot of hot oil or steam or where oil may splatter to the product.
Can cause the unit to make leak or other serious problem.
• Locations where electromagnetic waves is prevalent. The electromagnetic waves may cause the control system to
malfunction or causing an abnormal operation.
• Locations where inflammable gas might leak, where combined gasoline, methane or other volatile substances, car-
bon dust and other incendiary substances are found in the atmosphere. Leaked gas may accumulate around the unit,
can cause an serious explosion.
