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 ...
domestic hot water tank
3‑way valve
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.

Preparing water piping

3.2.1

To check the water volume and flow rate

Minimum water volume
If
The system contains a backup
heater
The system does NOT contain a
backup heater
(a) The internal water volume of the outdoor unit NOT
included.
NOTICE
When circulation in each space heating 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.
Minimum flow rate
Check that the minimum flow rate (required during defrost/backup
heater operation) in the installation is guaranteed in all conditions.
NOTICE
If glycol was added to the water circuit, and the
temperature of the water circuit is low, the flow rate will
NOT be displayed on the user interface. In this case, the
minimum flow rate can be checked by way of the pump
test (check that the user interface does NOT display error
7H).
NOTICE
When circulation in each or certain space heating loops is
controlled by remotely controlled valves, it is important that
the minimum flow rate is guaranteed, even if all valves are
closed. In case the minimum flow rate cannot be reached,
a flow error 7H will be generated (no heating/operation).
See the installer reference guide for more information.
