3 Preparation
3.1 Preparing the installation site
3.1.1 Installation site requirements of the
outdoor unit
Mind the spacing guidelines. See figure 1 on the inside of the front
cover.
The symbols can be interpreted as follows:
A,C Left side and right side obstacles (walls/baffle plates)
B Suction side obstacle (wall/baffle plate)
D Discharge side obstacle (wall/baffle plate)
E Top side obstacle (roof)
a,b,c,d,e Minimum service space between the unit and obstacles A,
B, C, D and E

INFORMATION
If shut-off valves are installed on the unit, provide a
minimum space of 400mm at the air inlet side. If shut‑off
valves are NOT installed on the unit, provide a minimum
space of 250mm.
If the system contains a domestic hot water tank, meet the following
requirements:
Maximum allowable distance
between outdoor unit and …
Distance
domestic hot water tank 10m
3‑way valve 10m
The outdoor unit is designed for outdoor installation only, and for
ambient temperatures ranging 10~43°C in cooling mode, –25~25°C
in space heating mode, and –25~35°C in domestic hot water
operation mode.
3.2 Preparing water piping
NOTICE
In case of plastic pipes, make sure they are fully oxygen
diffusion tight according to DIN 4726. The diffusion of
oxygen into the piping can lead to excessive corrosion.
3.2.1 To check the water volume and flow rate
Minimum water volume
Check that the total water volume in the installation is minimum 20l,
the internal water volume of the outdoor unit NOT included.
INFORMATION
In critical processes, or in rooms with a high heat load,
extra water might be required.
NOTICE
When circulation in each space heating/cooling loop is
controlled by remotely controlled valves, it is important that
the minimum water volume is guaranteed, even if all of the
valves are closed.
