WARNING!
At normal atmospheric pressure and
ambient temperatures, liquid coolant
vaporises so suddenly that on contact
with skin or eyes it can cause the tis-
sue to freeze (danger of going blind).
Always wear safety goggles and
protective gloves.
Never allow refrigerant to escape into
the atmosphere (high pressure at the
point of the leak).
When removing the service pipes
from the filling connections, never
hold the connections in the direction
of your body. Residual refrigerant
could escape.
WARNING!
Under the cover of the Daikin Altherma
EHS(X/H) temperatures of up to 90 °C
can arise during operation. During oper-
ation, hot water temperatures > 60 °C
arise.
– Touching components during or after
operation leads to a risk of burns.
– Water discharged during mainte-
nance and servicing work can cause
scalding on contact with the skin.
Before carrying out servicing and
maintenance work, allow the Daikin
Altherma EHS(X/H) to cool down
sufficiently.
Wear protective gloves.

WARNING!
Live parts can cause an electric shock
on contact and cause fatal burns and in-
juries.
Before beginning work on live parts,
disconnect all of the systems circuits
from the power supply (switch off
main switch, disconnect fuse) and
secure against unintentional restart.
Electrical connection and work on
electrical components must only be
carried out by qualified electricians
in compliance with valid standards
and guidelines as well as the specifi-
cations of the energy supply
company.
Covers off equipment and
servicing flaps are to be replaced
as soon as the work is completed.
1. Remove the cover hood and thermal insulation
(see section 4.3).
2. Carry out a functional inspection of the Daikin Altherma
EHS(X/H), as well as all installed accessory components
(Backup-Heater, solar installation) by checking the
temperature display and the switching states in the individual
modes.
3. If a Daikin solar system of the DrainBack
connected and in operation, switch this off and empty the
solar panels.
4. When operating the Daikin Altherma EHS(X/H) in a bivalent-
alternative system; switch off all heat generators and
deactivate the bivalent control unit.
5. Visual check of general condition of the Daikin Altherma
EHS(X/H).
6. Visual check of the water storage tank level (filling level
indicator)
Top up the water if necessary (see section 7.3), deter-
mine the reason for the low water level and remedy it.
The Daikin Altherma EHS(X/H) is designed to be low-
maintenance. No corrosion protection equipment is re-
quired (such as expendable anodes). This means there
is no need for maintenance work such as changing the
protective anodes or cleaning the inside of the storage
tank.
7. Check the connection of the safety overflow and drain hose
for leaks, free drainage and gradient.
If necessary, clean the safety overflow and drain hose and
relay it; replace damaged parts.
8. Visual check of connections, lines and safety pressure relief
valve. In the event of damage, determine the cause.
Replace defective parts.
9. Check all electrical components, connections, and cables.
Repair damaged parts or replace them.
