Preparation

5.1

Overview: Preparation

This chapter describes what you have to do and know before going
on-site.
It contains information about:
▪ Preparing the installation site
▪ Preparing the refrigerant piping
▪ Preparing the water piping
▪ Preparing the electrical wiring
5.2

Preparing installation site

5.2.1 Installation site requirements of the
outdoor unit
▪ Provide sufficient space around the unit for servicing and air
circulation.
▪ Make sure the installation site withstands the unit's weight and
vibration.
▪ Make sure the area is well ventilated. Do NOT block any
ventilation openings.
▪ Make sure the unit is level.
▪ Make sure to install the unit in a machine room that is free of
moisture. The unit is designed for indoor use only.
▪ Select the location of the unit in such a way that the sound
generated by the unit does not disturb anyone, and the location is
selected according the applicable legislation.
Do NOT install the unit in the following places:
▪ In potentially explosive atmospheres.
▪ In places where there is machinery that emits electromagnetic
waves. Electromagnetic waves may disturb the control system,
and cause malfunction of the equipment.
▪ In places where there is a risk of fire due to the leakage of
flammable gases (example: thinner or gasoline), carbon fibre,
ignitable dust.
▪ In places where corrosive gas (example: sulphurous acid gas) is
produced. Corrosion of copper pipes or soldered parts may cause
the refrigerant to leak.
