Start-up and taking out of service
5.1
Start-up
The instructions for integration into the hydraulic system, start-
up, operation of the control systems and rectifying faults and mal-
functions are contained in the installation and maintenance in-
structions of the (RPS4 and RPS3 25M) control system and
pump unit.
5.2
Decommissioning
5.2.1 Temporary shutdown
By switching off the Solaris R4 control unit at the main switch or
disconnecting the mains plug from the power supply, the ROTEX
solar system can be shut down temporarily.
If there is a danger of frost:
– put the ROTEX solar system back into operation
or
– suitable antifreeze measures must be applied to the con-
nected heating system and hot water storage tank (e.g.
draining).
5.2.2 Final shutdown
●
Take the ROTEX solar system out of operation (see
Chapter 5.2.1 "Temporary shutdown").
●
Disconnect the ROTEX solar system from all electrical and
water connections.
●
Dismantle the ROTEX solar system in accordance with the
assembly instructions (Chapter 4 "Installation") in reverse
order.
●
Dispose of the ROTEX solar system properly.
Recommendations for disposal
WARNING!
The solar system cannot be started until all
hydraulic and electrical connections have been
completed.
An incorrect start-up will adversely affect the
function and may damage the complete system.
Installation and start-up must therefore must
conducted by ROTEX-authorised and trained
heating experts.
Before start-up, the protective conductor re-
sistance and proper connection must be
checked.
CAUTION!
Setting up in frosty conditions can result in
damage to the entire system.
●
Start-up at outside temperatures below 0 °C
only when a water temperature of at least
5 °C is guaranteed in the solar circuit (e.g.
prior heating of the hot water storage tank).
ROTEX recommends not operating the instal-
lation in extremely frosty conditions.
CAUTION!
A heating system which is shut down can freeze
in the event of frost and may suffer damage.
●
Drain the heating system that is shut down if
there is danger of frost.
CAUTION!
Pumps switched off for a lengthy period can
seize.
For temporarily shut-down solar systems, the
protective function against seizing pumps
(pump kick function) is also deactivated.
●
When restarting, check the pump is working
correctly. In most cases, seized pumps can
be freed again manually.
If there is a risk of frost for a few days only, the excellent
heat insulation of the ROTEX hot water tank means that
it need not be drained as long as the storage tank tem-
perature is observed regularly and not permitted to fall
below +3 °C. This does not, however, provide any protection
against frost for the connected heat distribution system.
Thanks to the environmentally friendly design of the
solar system, ROTEX has complied with requirements
for environmentally sound disposal. During the disposal
process, the only waste created is that which can be
used for material or thermal recycling.
The materials used that are suitable for recycling can be sorted
into individual types.
