• A place which provides enough space around the outdoor unit as shown in the diagram.
• A place which can bear the weight of the outdoor unit and does not allow an increase in noise level and vibration.
• A place where the operation noise and discharged air do not disturb neighbors.
• A place which is not exposed to a strong wind.
• A place free of combustible gases.
• A place which does not block a passageway.
• When the outdoor unit is to be installed in an elevated position, be sure to secure its feet.
• This air conditioner accepts a connection piping length of up to 25 m.
• There is no need to add refrigerant as long as the length of the connection piping is 15 m or less.
• You will need to add 20 g of refrigerant per meter of added connection piping for installations requiring connection piping to be
between 16 m to 25 m.
• An allowable height level is up to 10 m.
• A place where the drain water does not cause any problems.
Precautions for Adding Refrigerant
• Use a scale having a precision with at least 10 g per index line when adding the refrigerant. Do not use a bathroom scale or similar
instrument.
• Use liquid refrigerant when refilling the refrigerant. Since the refrigerant is in liquid form, it can fill quickly. Therefore, perform the
filling operation carefully and insert the refrigerant gradually.
• Holes are provided on the base plate of the outdoor unit to ensure that the
defrost water produced during heating operations is drained off efficiently. If a
centralized drain is required when installing the unit on a balcony or wall, follow
the steps below to drain off the water.
1.
Proceed with water-proofing by installing the water-proof rubber caps
j
in the
2 elongated holes on the base plate of the outdoor unit.
[How to install the water-proof rubber caps]
1) Place four fingers into each cap, and insert the caps into the water drain
holes by pushing them into place from the underside of the base plate.
2) Press down on the outer circumferences of the caps to ensure that they
have been inserted tightly.
(Water leaks may result if the caps have not been inserted properly, if their
outer circumferences lift up or the caps catch on or wedge against
something.)
2.
Install the drain nipple
i
and a commercially available drain hose (with 16 mm
inside diameter), and drain off the water.
(For the position where the drain nipple
i
is installed, refer to the installation
diagram of the indoor and outdoor units.)
• Check that the outdoor unit is horizontal, and route the drain hose at a
downward sloped angle while ensuring that it is connected tautly.
5 INSTALLATION OF OUTDOOR UNIT
Installation Location
CAUTION
1.
Install the outdoor unit without anything blocking the discharging air.
2.
When the outdoor unit is installed in a place always exposed to strong winds like on the coast or on a high story of a
building, secure the normal fan operation using a duct or a wind shield.
3.
Especially in windy areas, install the unit to prevent the admission of wind.
4.
Installation in the following places may result in trouble. Do not install the unit in such places.
• A place full of machine oil.
• A saline-place such as the coast.
• A place full of sulfide gas.
• A place where high-frequency waves are likely to be generated, such
as from audio equipment, welders, and medical equipment.
