4.3.4 To fill the space heating circuit
To fill the space heating circuit, use a field supply filling kit. Make
sure you comply with the applicable legislation.
NOTICE
▪ Air in the water circuit can cause malfunctioning of the
backup heater. During filling, it may not be possible to
remove all the air from the circuit. Remaining air will be
removed through the automatic air purge valves during
the initial operating hours of the system. Additional
filling with water afterwards may be required.
▪ To purge the system, use the special function as
described in the chapter "7 Commissioning" [4 36].
This function should be used to purge the heat
exchanger coil of the domestic hot water tank.
4.3.5 To fill the domestic hot water tank
1 Open every hot water tap in turn to purge air from the system
pipe work.
2 Open the cold water supply valve.
3 Close all water taps after all air is purged.
4 Check for water leaks.
5 Manually operate the field-installed pressure relief valve to
ensure a free water flow through the discharge pipe.
4.3.6 To check for water leaks
Before insulating the water piping, it is important to detect water
leaks, in particular small leaks. Small leaks can easily be overseen,
but can cause damage to the unit and surroundings over a longer
period of time.
NOTICE
After water piping installation, check all connections for
leaks.
4.3.7 To insulate the water piping
The piping in the complete water circuit MUST be insulated to
prevent reduction of the heating capacity.
Consider that the space heating piping can condensate during
cooling operation. Foresee adequate insulation for these pipes.

DANGER: RISK OF ELECTROCUTION
WARNING
ALWAYS use multicore cable for power supply cables.
CAUTION
Do NOT push or place redundant cable length in the unit.
NOTICE
The distance between the high voltage and low voltage
cables should be at least 50mm.
5.1 About electrical compliance
For the models EGSAH/X06+10DA9W(G), the following statement…
Equipment complying with EN/IEC 61000‑3‑12 (European/
International Technical Standard setting the limits for harmonic
currents produced by equipment connected to public low-voltage
systems with input current >16A and ≤75A per phase.).
…is valid in the following cases:
