INFORMATION
▪ Protection against bursting: the glycol will prevent the
piping from bursting, but NOT the liquid inside the
piping from freezing.
▪ Protection against freezing: the glycol will prevent the
liquid inside the piping from freezing.
NOTICE
▪ The required concentration might differ depending on
the type of glycol. ALWAYS compare the requirements
from the table above with the specifications provided by
the glycol manufacturer. If necessary, meet the
requirements set by the glycol manufacturer.
▪ The added concentration of glycol should NEVER
exceed 35%.
▪ If the liquid in the system is frozen, the pump will NOT
be able to start. Mind that if you only prevent the
system from bursting, the liquid inside might still freeze.
▪ When water is at standstill inside the system, the
system is very likely to freeze and get damaged.
Glycol and the maximum allowed water volume
Adding glycol to the water circuit reduces the maximum allowed
water volume of the system. For more information, see the installer
reference guide (topic "To check the water volume and flow rate").
Glycol setting
NOTICE
If glycol is present in the system, setting [E-0D] must be
set to 1. If the glycol setting is NOT set correctly, the liquid
inside the piping can freeze.
Freeze protection by freeze protection valves
About freeze protection valves
When no glycol is added to the water, you can use freeze protection
valves to drain the water from the system before it can freeze.
▪ Install freeze protection valves (field supply) at all lowest points of
the field piping.
▪ Normally closed valves (located indoors near the piping entry/exit
points) can prevent that all water from indoor piping is drained
when the freeze protection valves open.
NOTICE
When freeze protection valves are installed, set the
minimum cooling setpoint (default=7°C) at least 2°C higher
than the maximum opening temperature of the freeze
protection valve. If lower, freeze protection valves can
open during cooling operation.
For more information, see the installer reference guide.
5.2.4
To fill the domestic hot water tank
See the installation manual of the domestic hot water tank.
5.2.5
To insulate the water piping
The piping in the complete water circuit MUST be insulated to
prevent condensation during cooling operation and reduction of the
heating and cooling capacity.
Outdoor water piping insulation
NOTICE
Outside piping. Make sure the outside piping is insulated
as instructed to protect against hazards.

For piping in free air, it is recommended to use the insulation
thickness as shown in below table as a minimum (with λ=0.039 W/
mK).

For other cases the minimum insulation thickness can be determined
using the Hydronic Piping Calculation tool.
The Hydronic Piping Calculation tool is part of the Heating Solutions
Navigator

Please contact your dealer if you have no access to Heating
Solutions Navigator.
This recommendation ensures good operation of the unit, however,
local regulations may differ and shall be followed.

Electrical installation
DANGER: RISK OF ELECTROCUTION
WARNING
Rotating fan. Before powering ON the outdoor unit, make
sure that the discharge grille covers the fan as protection
against a rotating fan. See
grille" [ 4 9].
WARNING
ALWAYS use multicore cable for power supply cables.
CAUTION
Do NOT push or place redundant cable length in the unit.
NOTICE
The distance between the high voltage and low voltage
cables should be at least 50 mm.
