3.6 Pressure test and filling the coolant circuit
RISK OF ENVIRONMENTAL DAMAGE!
Important information regarding the coolant used.
The complete heat pump system contains refrigerant
wi
th fluorinated greenhouse gases which damage the
environment if released.
Coolant type: R410A
GWP* value: 2087,5
* GWP = Global Warning Potential
Fill in the total coolant filling quantity on the
supplied label on the heat pump exterior unit (for
information consult the installation instructions for
the heat pump exterior unit).
N
ever allow coolant to be released into the atmos-
phere - always suction it off and recycle using a
suitable recycling
device.
Perform pre
ssure test with nitrogen.
Use nitrogen 4.0 or higher.
Maximum 40 bar.
Af
ter leak search is complete, completely drain.
Vacuum lin
es.
Pressure to be achieved: 1 mbar absolute.
Time: minimum 1 h
Che
ck whether additional coolant is needed for primer filling,
fill where necessary.
Open stop valve on exterior unit completely until the stop.
Tighten loosely.
Reas
semble valve caps.
Check whether the storage tank temperature sensors t
DHW1
and t
DHW2
are inserted to a depth of 80 cm.
3.7 Filling the system with water
Only fill the Daikin Altherma EHS(X/H) following the sequence
stated below and once all installation work is complete.
3.7.1 Checking the water quality and adjusting the
pressure gauge
Observe the information on the water connection and water
quality in accordance with section 3.3.
The correct minimum pressure markin
g must be set on the
pressure gauge installed by the customer before filling the
system for the first time:
Rotate the pressure
gauge glass in such a way that the
minimum pressure mark corresponds to the system
height +2 m (1 m water column = 0.1 bar).
3.7.2 Filling the hot water heat exchanger
Open the shutoff valve for the cold water supply pipe.
Open the hot water tap connections so that the draw-off
volume can be set as high as possible.
On
ce water has been discharged from the tap connections,
do not interrupt the cold water flow; this will ensure that the
heat exchanger will be fully vented and that any impurities or
residue will be discharged.
3.7.3 Filling the storage tank
See chapter 6.4.
3.7.4 Filling the heating system
See chapter 6.5.
