5.1.1 To check the water volume and flow rate
Minimum water volume
Check that the total water volume in the installation is higher than
the minimum water volume, the internal water volume of the outdoor
unit NOT included:
If… Then the minimum water
volume is…
Cooling operation 20l
Heating/defrost operation and…
Preheating on the tank is possible.
This is possible in the following
cases:
▪ EKHWP* tank + booster heater
▪ EKHWS*D* tank + booster heater
+ DHW pump
0l
Preheating on the tank is not
possible, but a backup heater
(internal or external) is present.
20l
Preheating on the tank is not
possible, and there is no backup
heater.
50l
NOTICE
When circulation in each space heating/cooling 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 (if applicable)) in the installation is guaranteed in all
conditions.
If operation is… Then the minimum required
flow rate is…
Cooling 20l/min
Heating/defrost when outdoor
temperature is above –5°C
Heating/defrost when outdoor
temperature is below –5°C
22l/min
Domestic hot water production 28l/min
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.
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 or operation).
See the installer reference guide for more information.
See the recommended procedure as described in "9.2 Checklist
during commissioning"[437].
5.1.2 Third-party tank requirements
In case of a third-party tank, the tank shall adhere to the following
requirements:
▪ The heat exchanger coil of the tank is ≥1.05m².
▪ The tank thermistor must be located above the heat exchanger
coil.
▪ The booster heater must be located above the heat exchanger
coil.
NOTICE
Performance. Performance data for third-party tanks
CANNOT be provided, and performance CANNOT be
guaranteed.
5.2 Connecting water piping
5.2.1 To connect the water piping
NOTICE
Do NOT use excessive force when connecting the field
piping and make sure the piping is aligned properly.
Deformation of the piping can cause malfunctioning of the
unit.
NOTICE
When connecting the field piping, hold the nut on the inside
of the unit in place using a spanner to provide extra
leverage.
