5. REFRIGERANT INSTALLATION
1. Precautions during refrigerant installation.
Use clean pipes with no dust inside.
The pipe may corrode with the presence of
fl
uorine dust which will adversely affect the refrigerant piping system due to deter ioration
of the refrigerant oil, etc.
This unit is speci
fi
cally for R32. Ensure to adhere to the following items and install accordingly:
•
Use pipe cutters and
fl
aring tools which are specially designed for use with R32.
•
When connecting with
fl
aring tools, coat the
fl
are section with ether-based oil.
•
Ensure to use
fl
are 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 3m.
•
Carefully handle the liquid refrigerant, as it may cause a frostbite.
•
Do not release refrigerants during the piping works for installing, re-installing and repairing refrigeration parts.
For indoor unit refrigerant piping installation, refer to the installation instruction manual that comes with that indoor 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 dam aging 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 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 mou nt 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 belo
w 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.

Precautions when operating the 2/3-way valve for piping installation
Do not open the 2/3-way valve until the piping installation is completed.
•
It is closed during shipment.
•
When removing or tightening the gas tube
fl
are nut, use 2 adjustable wrenches together:
one at the gas tube
fl
are nut, and the other at part A.
Refer to the following table for the tightening torque of the 2/3-way valve
fl
are nuts.
•
If the nuts are over tightened, they may cause the
fl
ares to break or leak.
Do not add additional force to the valve’s cover.
•
Using spanners on the cover or valve itself (other than the hexagonal parts) may cause gas leakage.
Avoid using spanners on the cover or parts other than the hexagonal part of the valve.
