4 Commissioning
4.1
Initial
commissioning
The Daikin Altherma EHS(X/H) may be commissioned only by
authorised and trained heating experts.
4.2 Re-commissioning
4.2.1 Requirements
– The Daikin Altherma EHS(X/H) is fully connected.
– The coolant system is dehumidified and filled with the speci-
fied amount of coolant.
– The heating and hot water systems are filled and charged at
the right pressure (see chapter 7.5).
– The storage tank is filled up to the overflow (see chapter 7.4).
4.2.2 Start-up
1.
Check the cold water connection and, where necessary, fill
the potable water heat exchanger.
2.
Turn power supply to Daikin Altherma EHS(X/H) on.
3.
Wait for the start phase.
4.
After the start phase has completed, in heating mode,
evacuate the heating system, check the installation pressure
and adjust where necessary (max. 3 bar).
5.
Carry out a visual inspection for leaks on all joints internally.
Seal any leaks that occur in a professional manner.
6.
Set the dial on the controller to the required operating mode.
7.
If a Daikin
solar system is connected, commission this in
accordance with instructions provided. After disconnecting
the Daikin
solar system, check the level in the buffer
storage tank once again.
WARNING!
●
A Daikin Altherma EHS(X/H) that is installed or
started incorrectly may not operate properly and is
dangerous for the health and safety of individuals.
CAUTION!
A Daikin Altherma EHS(X/H) not put into operation
properly can lead to damage to property and the envi-
ronment.
●
Minimum requirements regarding the quality of
filling and supplementary water:
– Water hardness (calcium and magnesium, cal-
culated as calcium carbonate):
≤
3 mmol/l
– Conductivity:
≤
2700
μ
S/cm
– Chloride:
≤
250 mg/l
– Sulphate:
≤
250 mg/l
– pH value (heating water): 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.
●
During system operation, the water pressure at the
pressure gauge must be checked at regular
intervals. If necessary, readjust by refilling
CAUTION!
Commissioning in frosty conditions can result in
damage to the entire heating system.
●
Only commission at temperatures below 0 °C when
a water temperature of at least 5 °C can be
guaranteed in the heating system and storage
tank.
Daikin recommends that you avoid operating the
system in extremely frosty conditions.
If the storage temperature falls below a certain
minimum value, the safety settings of the Daikin
Altherma EHS(X/H) prevent the operation of the heat
pump in the case of low external temperatures:
–
External temperature < -2 °C
, minimum
storage
temperature = 30 °C
–
External temperature < 12 °C
, minimum
storage
temperature = 23 °C
.
Without backup-heater:
The storage tank water must be heated to the minimum
required storage temperature by an external heater.
With backup heater (EKBUxx):
With an outdoor temperature < 12 °C and a storage tank
temperature < 35 °C, the backup heater (EKBUxx) is
switched on automatically on in order to heat up the
storage tank water to at least 35 °C.
Air Purge
(Can only be performed by an expert heating
technician.)
