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.

5.2.7

—

The piping in the complete water circuit MUST be insulated to

prevent condensation during cooling operation and reduction of the

heating and cooling capacity.
