▪ In case of an installation site where sides A+B+C+D have
obstacles, the wall heights of sides A+C have no impact on
service space dimensions. Refer to the figure above for impact of
wall heights of sides B+D on service space dimensions.
▪ In case of an installation site where only the sides A+B have
obstacles, the wall heights have no influence on any indicated
service space dimensions.
▪ The installation space required on these drawings are for full load
heating operation without considering possible ice accumulation. If
the location of the installation is in a cold climate, then all
dimensions above should be >500 mm to avoid accumulation of
ice in between the outdoor units.
INFORMATION
The service space dimensions in above figure are based
on cooling operation at 35°C ambient temperature
(standard conditions).
INFORMATION
Further specifications can be found in the technical
engineering data.

Wiring diagram: Outdoor unit
Refer to the wiring diagram sticker on the unit. The abbreviations
used are listed below:
INFORMATION
The wiring diagram on the outdoor unit is only for the
outdoor unit. For the indoor unit or optional electrical
components, refer to the wiring diagram of the indoor unit.

Symbols (see below).
2
Refer to the installation or service manual on how to use
BS1~BS3 push buttons and DS1~DS2 switches.
3
Do NOT operate the unit by short-circuiting protection device
S1PH.
4
Refer to the installation manual for connection wiring to
indoor–outdoor transmission F1‑F2 and outdoor‑multi
transmission Q1‑Q2.
5
When using the central control system, connect outdoor–
outdoor transmission F1‑F2.
6
The capacity of the contact is 220~240V AC – 0.5 A (rush
current needs 3 A or less).
7
Use dry contact for micro current (10 mA or less, 15 V DC).
8
When using the optional adapter, refer to the installation
manual of the optional adapter.
