4. TRANSPORT AND INSTALL THE OUTDOOR UNIT
Transporting
1. Transport the outdoor unit in its original packaging as close as possible to the installation location.
2. In the event that the unit needs to be lifted or suspended, use a rope or belt and use cloth or wood as padding to avoid damaging the unit.
3. Use the side handles to carry the unit and be careful not to touch the fan with your hand or any objects.
Installation
CAUTION
Route the tubing so that it does not contact the compressor, panel, or other parts inside the unit. Increased noise will result if the
tubing contacts these parts.
When routing the tubing, use a tube bender to bend the tubes.
In cold-weather regions, in order to prevent drainage water from freezing, do not install the drain socket cap.
Also take steps to prevent water from accumulating around the unit.
1. Read the “Select the outdoor unit installation location” thoroughly before installing the outdoor unit.
2. When installing to a concrete or solid surface, use M10 or a W 3/8 bolts and nuts to secure the unit. Ensure that it installed upright on a horizontal plane.
(Use an anchor bolt for the installation as shown in the diagram below.)
3. Avoid installing on the slanted roof.
4. In the even where the roof is at risk of receiving oscillations or vibrations, secure the unit with a seismic isolating mount or vibration absorbing rubber.
5. The drain water will be discharged from the unit during heating or defrosting
operation mode.
Select an appropriate location with good drainage system.
(In winter, there is a risk of slipping caused by freezing depending on the installation
location.)
* Ensure a height of 15 cm or more at the feet on both sides of the unit.
* Precautions for Installation in Heavy Snow Areas.
The platform should be higher than the maximum snow depth + 50 cm.
(In this case, leave clearance below the unit for the drain tube, and to prevent
freezing of drainage water in cold-weather regions.)
* Please consult us if installing the drain socket (Field supply).
* When using a drain tube, install the drain socket (Field supply) onto the drain hole.
Seal the other drain hole with the rubber cap (Field supply). For details, refer to the
instruction manual of the drain socket (Field supply).
After completing the installation work of the drain socket, make sure that the water
does not leak from any part of connection.
* In cold regions (where the outdoor temperature can drop to below 0° for 2 to
3 consecutive days), the drain water may freeze and may prevent the fan from
operating. For this case, do not use the drain socket (Field supply).

5. REFRIGERANT INSTALLATION
For indoor unit refrigerant tubing installation, refer to the installation instruction manual that comes with that
indoor unit. Do not reuse existing tubing, install new tubing.
1. Precautions during refrigerant installation.
Use clean tubes with no dust inside.
The tube ma
y corrode with the presence of fluo
rine dust which will adversely affect the refrigerant
tubing system due to deterioration of the refrigerant oil, etc.
This unit is specifically
for R32. Ensure to adhere to the following items and install accordingly:
•
•
•
•
Only for storing or for open tubes.
•
Set the lower limit of the allowable tube length to 5m.
If the tube is shorter than 5m, the refrigerant may become ov
erfilled and a pro
blem such as
abnormal high pressure could occur.
•
Carefully handle the liquid refrigerant, as it may cause a frostbite.
•
Do not release refrigerants during the tubing works for installing, re-installing and repairing
refrigeration parts.
2. The local tubes can protrude from any four directions.
Make holes in the tube panel for the tubes to penetrate it and lay the tubes accordingly.
•
It is recommended to apply additional substance to the cut area for anti-rust protection.
Ensure to install tube panels to prevent rain water from getting into the unit.
Close the gap at the tube connected area with putty or heat insulator (field supply).
•
If an insect or small animal enters the outdoor unit, there is the risk of shorting in the
product electronic casing.
[Remove the front panel]
(1) Remove the 2 mounting screws.
(2) Slide the front panel using your hands downwards to release the pawls.
Then remove by pulling the panel towards you.
