Filling, Topping Up The Heating System - Daikin Altherma EHSX04P50D Installations- Und Wartungsanleitung

7 Inspection and maintenance
INFORMATION
If the storage tank temperature falls below specific min-
imum values, the safety settings of the Daikin Altherma
EHS(X/H) prevent the heat pump from being operated at
low outside temperatures:
- Outside temperature < -2 °C, minimum storage tank tem-
perature = 30 °C
- Outside temperature < 12 °C, minimum storage tank tem-
perature = 23 °C
Without backup heater:
The storage tank water must be heated to the required
minimum storage tank temperature with an external heater
booster.
With backup heater (EKBUxx):
At an outside temperature of < 12 °C and a storage tank
temperature of < 35 °C, the backup heater (EKBUxx) is
automatically switched on to heat the storage tank water to
at least 35 °C.
▪ To speed up the heating process with the backup
heater, temporarily set the [Config. of external heat
source] parameter = "1" and [Ext. hot water power] para-
meter to the maximum value of the backup heater
[→ Main menu → Settings → Ext. Source].
▪ Select the [1x Hot Water] parameter in the "User" menu
and switch it on. After the heating has completed, switch
off the parameter again [→ Main menu → User → 1x
Load].

Filling, topping up the heating system

DANGER: RISK OF ELECTROCUTION
During the filling process, water can escape from any leak-
ing points and can cause an electric shock if it comes into
contact with live parts.
▪ Before the filling process, de-energise the Daikin
Altherma EHS(X/H).
▪ After the first filling and before switching on the Daikin
Altherma EHS(X/H) at the mains switch, check whether
all electric parts and connection points are dry.
WARNING
Polluted domestic water is hazardous to health.
▪ When filling the heating system, make sure that heating
water cannot flow back into the domestic water pipe.
