Start-up

WARNING!
A DAIKIN EKHHP that is installed or started in-
correctly may not operate properly and is dan-
gerous for the health and safety of individuals.
The DAIKIN hot water heat pump may only be
started up by authorised and trained heating ex-
perts.
CAUTION!
A DAIKIN EKHHP not put into operation
properly can lead to damage to property and the
environment.
● Observe the relevant regulations of
technology to prevent creation of corrosion
products and deposits. Minimum require-
ments regarding the quality of filling and
supplementary water:
– Water hardness (calcium and magnesium,
calculated as calcium carbonate):
≤ 3 mmol/l
– Conductivity: ≤ 1500 (ideal: ≤ 100) μS/cm
– Chloride: ≤ 250 mg/l
– Sulphate: ≤ 250 mg/l
– pH value: 6.5 - 8.5.
● If the above-mentioned minimum water
quality requirements set by the local water
supply company cannot be guaranteed,
suitable water treatment measures must be
taken.
● The domestic water quality must comply with
the EU Guideline 98/83 EC and the
regionaly-applicable regulations.
CAUTION!
If the DAIKIN EKHHP is started when the
storage tank is not completely full a reduction
in output may arise when heating, or to
destruction of the integrated Booster Heater
(BSH) and may cause an electrical fault.
● DAIKIN EKHHP only to be operated with full
storage tank.

5.1 Start-up

5.1.1 Requirements:

– The DAIKIN EKHHP system is set up and completely con-
nected.
– The coolant system is dehumidified and filled with the speci-
fied amount of coolant.
– The hot water distribution network is bled and has the correct
pressure applied (see Section 4.7).
– The storage tank is filled up to the overflow (see Section 9.2).
– Optional accessories have been mounted on and connected
up.
After the DAIKIN EKHHP was installed and connected com-
pletely, it will need to be undergo a one-time adaptation to the in-
stallation environment to be carried out by technical personnel
(configuration of optional accessories, setting the parameters).
After this configuration is complete, the installation is ready for
operation and the operator can make additional custom configu-
rations on it.
The heating expert must instruct the user, generate the commis-
sioning report and fill it in.

5.1.2 Start the system

● Check all the points on the enclosed checklist. Document the
test result.
● Switch on the power supply at the distributor box of the house
installation for the DAIKIN hot water heat pump.
● Switching DAIKIN EKHHP on.
● Perform a test run:
– Allow the temperatures to be displayed (see
Section 7.2.3).
– Test the hot water generation function. Select a higher set
hot water temperature so that the heating function is acti-
vated (see Section 7.3.1).
● Sign the check list, together with the operator.
Only if it is possible to answer all items on the check list by Yes,
is it allowed to commission and hand over the DAIKIN hot water
heat pump to the operator.
