11. Check the system water pressure on the RoCon HP controller
of the Daikin Altherma EHS(X/H).
Top up the water in the heating system if necessary, until
the pressure display is within the permitted range
(see section 6.5).
12. Cl
ean plastic surface of Daikin Altherma EHS(X/H) with a
soft cloth and mild cleaning agent. Do not use any
cleaners with aggressive solvents (damage to the plastic
surface may occur).
13. Refit the cover (see section 6.2).
14. Servicing of the external unit and other heating components
connected to the Daikin Altherma EHS(X/H) should be carried
out as specified in the respective associated installation and
operating manuals.
15. C
omplete the confirmation of servicing in the supplied
operating manual of the Daikin Altherma EHS(X/H).
6.4 Filling and topping up the storage tank
CAUTION!
Filling the storage container with excessive water
pre
ssure or at too great a flow speed can result in
damage to the Daikin Altherma EHS(X/H).
Only fill with a water pressure
<6 bar and a flow
speed <15 l/min.
UK only!
CAUTION!
If filling or topping up the storage tank is done by
means of the boiler filling and drain valve, a temporary
filling loop must be used with the appropriate backflow
prevention device in accordance with clause G24.2,
Guidance to the Water Supply (Water Fittings)
Regulations 1999.
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 tempera
ture < -2 °C, minimum storage
temperature = 30 °C
Ex
ternal 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
ta
nk temperature < 35 °C, the backup heater (BUH) is
switched on automatically on in order to heat up the
storage tank water to at least 35 °C.
In order to accelerate the heating process with
the back-up heater, temporarily
Parameter [
Function Heating Rod] = "1" and
Set parameter [Power DHW] to the maximum
value of the back-up heater.
Switch the rotary switch to operating mode
and set the parameter [1x Hot Water] to "On".
Following successful heating, reset the parame-
ters to "Off".
Without installed solar system
Connect the filling hose with backflush prevention (1/2") to
the connection "DrainBack Solar - feed" (see fig. 6-2,
item 1).
F
ill the storage tank on the Daikin Altherma EHS(X/H) until
water comes out of the connection (fig. 6-2, ite
m 23), that
has been connected as the safety overflow.
Disconnect the filling hose with backflush prevention (1/2")
again.
With KFE filling connection or with installed solar
system (see also chapter 5.1)
Without solar system: KFE filling connection (accessory
KFE BA) at the filling and draining connection of the Daikin
Altherma EHS(X/H) (fig. 2-2 to fig. 2-5, item 10)
or
with solar system: Mount the KF
E filling connection
(accessory KFE BA) at the connection elbow of the
control and pump unit (EKSRPS3B).
Connect the filling hose with backflush prevention (1/2") to
the previously installed KFE cock.
F
ill the storage tank on the Daikin Altherma EHS(X/H) until
water comes out of the connection (fig. 6-2, item 23), that
has be
en connected as the safety overflow.
Disconnect the filling hose with backflush prevention (1/2")
again.
