CAUTION
Risk of burns on hot surfaces
Hot surfaces in heating systems can cause burns to the skin.
• Wear protective gloves.
• Please place appropriate warning signs in the vicinity of the device.
 Note!
Confirm that installation and start-up have been carried out correctly
using the installation, start-up and maintenance certificate. This action is
a prerequisite for the making of warranty claims.
– Have the Reflex Customer Service carry out commissioning and the
annual maintenance.
7.1 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. Commission the storage
tank 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 water-side connection of the device to the make-up supply has been
created and is operational.
• The connection pipes of the device have been purged and cleaned of
welding residue and dirt before commissioning.
• The entire facility system is filled with water and all gases have been vented
in order to ensure a circulation through the entire system.
• The electrical connection has been created according to applicable national
and local regulations.
7.2 Determining the P
controller
The "p " minimum operating pressure is determined by the location of the pressure
0
maintaining device. The controller calculates the switching points for the "PV"
control ball valve and the "PU" pumps from the minimum operating pressure.
