9 Service and maintenance
9.1 General overview of service and
maintenance
Regular inspection and maintenance of the heating system re-
duces energy consumption and ensures a long life and smooth
operation.
Tests performed during the annual service
– General condition of the heating system, visual inspection of
connections and pipes.
– Check and clean the condensate drain.
– Check of the water pressure for the cold water supply
(<6 bar), pressure reducer installation or adjustment as
required.
– Burner operation and burner settings.
– Visual inspection of storage tank water container fill level (see
chap. 9.2.2).
Top up water if required (see chap. 9.2.4) and also deter-
mine and remedy the cause for the low water level.
– Check the system water pressure on the RoCon BF controller
for the ROTEX GCU compact.
Top up water in the heating system until the pressure dis-
play is in the permissible range (see chap. 9.2.5).
Maintenance work to be carried out annually
– Cleaning the burner components, the combustion chamber
and the heating surfaces.
– External cleaning of the storage tank and the protective
cover.
– Replacement of the wearing parts if required).
– Documentation of the maintenance work in the operating
manual.
– Before restart of the ROTEX GCU compact after mainte-
nance work, the conditions for start-up according to chap. 5.2
must be checked and fulfilled.
9.2 Service and maintenance tasks
Cleaning the protective cover and storage tank
●
The low-maintenance plastic only needs to be cleaned with a
soft cloth and a mild detergent.
●
Do not use any cleaners with aggressive solvents (damage to
the plastic surface may occur).
9.2.1 Checking the connections and pipes
●
Remove the protective cover
●
Check all (flue) gas and water lines and connections for leaks
and integrity. If damaged, determine the cause and change
the damaged parts.
●
Check all components of the flue system for leakage and
damage. Repair damaged parts or replace them.
●
Check all electrical components, connections, and pipes.
Repair damaged parts.
Have the service and maintenance been carried out by
authorised and trained heating technicians once a year
and, if possible,
before the heating period
. This will
avoid malfunctions during the heating period.
ROTEX recommends an inspection and maintenance
contract to ensure regular inspection and maintenance.
WARNING!
Touching live parts can result in an electric shock and lead to
potentially fatal injuries and burns.
●
Before beginning maintenance work, disconnect the ROTEX
GCU compact from the power supply (fuse, switch off main
switch) and secure against unintentional restart.
CAUTION!
Danger of burning on hot surfaces.
●
Let the burner cool down for a reasonably long time before
maintenance and service work.
●
Wear protective gloves.
WARNING!
Improperly performed work on power or gas lines can endanger
life and health and hinder the operation of the ROTEX
GCU compact.
●
Damage repair to power and gas lines on the ROTEX
GCU compact may only be carried out by heating techni-
cians authorised and trained by the gas or power supply
company.
