To Fill The Domestic Hot Water Tank; To Insulate The Water Piping; Electrical Installation; About Electrical Compliance - Daikin EBLA08E23V3 Installation Manual

▪ Install freeze protection valves (optional – field supply) at all
lowest points of the field piping.
▪ Normally closed valves (recommended – field supply) 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.

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 which can

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.
