Note!
Confirm that installation and start-up have been carried out correctly
using the installation and commissioning certificate. This action is a
prerequisite for the making of warranty claims.
–
Have the Reflex Customer Service carry out commissioning and
the annual maintenance.
8.1
Checking the requirements for commissioning
The device will be ready for initial commissioning when the tasks described in
the "Installation" chapter have been completed. The system designer or an
assigned expert is responsible for carrying out the commissioning (e.g. by
Reflex's Customer Service). Commission the pressurisation system according to
the information in the corresponding installation manual. Note the following
information on initial commissioning:
•
The control unit is connected to the primary tank and the secondary tanks,
if provided.
•
The water connections of the tanks to the facility system are established.
•
The tanks are not filled with water.
•
The valves for emptying the tanks are open.
•
The facility system is filled with water and gas-vented.
•
The electrical connection has been created according to applicable
national and local regulations.

The start routine is used to set the required parameters for the device
commissioning. It commences with the first activation of the controller and can
be run only once. Parameter changes or checks are possible after the start
routine in the customer menu is exited, 10.2 "Configuring settings in the
