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
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 at right.)
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 the winter, there is risk of slipping due to freezing,
and depending on the installation set up there is risk of drain water running overhead.)
Please consult us if installing drain elbows.
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 elbow.
REFRIGERANT INSTALLATION
For indoor unit refrigerant piping installation, refer to the Installation Instruction manual that comes with that indoor
unit. Do not reuse existing piping, install new piping.
1. Precautions during refrigerant installation.
Use clean pipes with no dust inside.
The pipe may corrode with the presence of fluorine dust which will adversely affect the refrigerant piping
system due to deterioration of the refrigerant oil, etc.
This unit is specifically for R410A. Ensure to adhere to the
following items and install accordingly:
• Use pipe cutters and flaring tools which are specially
designed for use with R410A.
• When connecting with flaring tools, coat the flare section
with ether-based oil.
• Ensure to use flare nuts supplied with the unit when
connecting this unit.
• Only for storing or for open pipes.
• Set the lower limit of the allowable pipe length to 5m.
If the pipe is shorter than 5m, the refrigerant may become
overfilled and a problem such as abnormal high pressure
could occur.
2. The local pipes can protrude from any four directions.
Make holes in the pipe panel for the pipes to penetrate it
and lay the pipes accordingly.
• It is recommended to apply additional substance to the
cut area for anti-rust protection.
Ensure to install pipe panels to prevent rain water from getting into the unit.
Close the gap at the pipe connected area with putty or heat insulator (locally supplied).
• If an insect or small animal enters the outdoor unit, there is the risk of shorting in the product electronic casing.
