Service and maintenance
The ROTEX Sanicube / HybridCube is practically maintenance
free as a result of its design. No corrosion protection equipment
is required (such as sacrificial anodes). This means there is no
need for maintenance work such as changing the protective
anodes or cleaning the inside of the storage tank.
Regular inspection of the domestic hot water storage tank
guarantees a long working life and fault-free operation.
Tests performed during the annual service:
Ɣ
Carry out a functional inspection of the electric immersion
heater or booster heater by checking the temperature display
and the switching states in the individual modes:
– Without connection to a ROTEX heat pump: see
section 7.1.2
– With connection to a ROTEX heat pump: see chapter
"Operation" in the associated installation and operating
instruction.
Ɣ
If a solar system is connected and is in operation, switch it off
and empty the solar panels.
Ɣ
Visual inspection of the general condition of the domestic hot
water storage tank.
Ɣ
Visual check of the water storage tank level (filling level
indicator)
Î
If necessary, replenish water; determine the reason for
the low water level and remedy it.
Ɣ
Check the connection of the safety overflow and drain hose
for leaks, free drainage and gradient.
Î
If necessary, clean the safety overflow and drain hose and
relay it; replace damaged parts.
Ɣ
Visual check of connections and pipes. In the event of
damage, determine the cause.
Î
Replace defective parts.
Ɣ
Check all electrical components, connections, and cables.
Î
Repair damaged parts or replace them.
Ɣ
Check the water pressure of the cold water supply (<6 bar)
Î
and if necessary the fitting or adjustment of the pressure
reducer.
Clean the storage tank (annually)
Ɣ
The low-maintenance plastic must only be
cleaned
with a
soft cloth and a mild detergent
. Do not use cleaning agents
containing aggressive solvents, as this will damage the
plastic surface.
WARNING!
Live parts can cause an electric shock on contact and
cause fatal burns or injuries.
Ɣ
If there is an electric immersion heater / booster
heater or regulation and pump station installed in
the hot water storage tank then these components
must be isolated from the power supply before
starting the inspection and maintenance work (e.g.
fuse, main switch switched off and secured against
inadvertent switching on again).
WARNING!
All work performed on live components must be
carried out in accordance with the proper procedures,
otherwise there may be a danger to the life and health
of individuals and the function may be impaired.
Ɣ
Rectification of damage to live components may
only be carried out by heating specialists
authorised and recognised by the energy supply
company.
