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.
8.2.8 To fill the domestic hot water tank
1 Open every hot water tap in turn to purge air from the system pipe work.
2 Open the cold water supply valve.
3 Close all water taps after all air is purged.
4 Check for water leaks.
8.2.9 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).
Piping length (m) Minimum insulation thickness (mm)
<20 19
20~30 32
30~40 40
40~50 50
For other cases the minimum insulation thickness can be determined using the
Hydronic Piping Calculation tool.
The Hydronic Piping Calculation tool also calculates the maximum hydronic piping
length from the indoor unit to the outdoor unit based on the emitter pressure drop
or the other way around.
The Hydronic Piping Calculation tool is part of the Heating Solutions Navigator
which can be reached via https://professional.standbyme.daikin.eu.
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.
