Rotex GasSolarUnit Series User Manual

[ 49 ]
Check for unrestricted draining by observing,
for example, the way the cleaning fluid drains
out of the combustion chamber.
Note: The condensate that is
channelled into the cylinder from
the boiler and the flue is slightly
acidic. It is routed into the unpressurised
area of the cylinder. That way ensures,
that in normal operation, the cylinder is
always full. A long-acting neutralising
agent in the cylinder ensures that the
liquid draining from the cylinder is
p
H
-neutral. Any residues remain in the
unpressurised area of the cylinder.
Sedimentation does not normally occur in
the drain line, if the condensate line is
correctly installed, i.e. with a constant
slope.
Nevertheless, check that the drain is
unrestricted and that the cylinder is full.
Chapter 6: Inspection and maintenance
6.1 Inspection and maintenance work
Regular inspection and maintenance of your
heating system lowers the energy
consumption and safeguards a long service life
as well as the trouble-free operation of the
system. For those reasons, have the system
inspected and serviced annually by a
competent heating contractor. The service
should, where possible, be carried out before
the heating season. That prevents faults
during the heating season from occurring.
As part of the annual inspection, the current
state of the heating system should be
established through visual inspection, tests
and measurements.
Maintenance includes activities, that should
be carried out subject to demand, to maintain
the design condition of the system. That
includes, for example, cleaning of the burner
components, the combustion chamber and
heating surfaces, the replacement of wearing
parts and the burner adjustment.
To safeguard that this is done regularly,
we recommend you take out a
maintenance contract.
Specifically, the following work should be
carried out annually:
1. Removing the silencer hood
Inspection and maintenance require the
removal of the silencer hood from the ROTEX
GasSolarUnit.
Caution: Risk of burning
Burner and boiler components
below the silencer hood can be
very hot. Let the equipment cool down
sufficiently before touching these
components or wear protective gloves.
Warning: Electric shocks can
cause severe burns and life-
threatening injuries. Switch OFF
the mains power supply before removing
the silencer hood.
The silencer hood sits at the top of the cylinder
and can be lifted off easily after undoing the
two fixing screws (Fig. 6.1.1).
2. Checking the connections and
cables/leads
Check all components in contact with gas and
water for leaks/soundness as well as potential
damage; replace, if required.
Check all electrical and electronic components,
connections and cables and casing
components for potential damage; repair, if
required.
If faults with the electrical or gas supply are
discovered, ask a qualified electrical
contractor/gas fitter to remedy the fault.
3. Cleaning the condensate drain and checking
the cylinder fill level
Open the condensate drain (connection and
drain lines) and check for contamination;
clean, if required and re-seal (Fig. 6.1.2).
If a Solaris system is connected and in
operation, switch that system OFF and wait,
until all collectors have drained.
It must be apparent when connecting the
overflow connection that the cylinder is
completely full. If there is no water at the top
edge, top up the cylinder with water.
Determine and remedy the reason for the low
level (e.g. leak in the Solaris system).
1. Step 4: Remove the fixing screws
2. Step 4: Tilt the hood
3. Step 4: Lift the hood forward and up
