8  Installation and commissioning

DANGER

Electrical energy!

Risk of death from electric shock.

•  Work on parts carrying live voltage must be carried out by 

qualified electricians only.

•  Disconnect the power supply of the system and secure it 

to prevent it from being switched on again before carrying 
out any installation, maintenance, cleaning or repair work.

NOTICE

The installation and commissioning of

the FRG3015-F RV must be carried out only by 
trained personnel who have been authorized by the 
manufacturer. 

!

!

 

CAUTION

When repairing the unit or replacing

parts, be sure to observe the specified installation posi-
tions and flow directions of the parts being replaced!

!

!

 

CAUTION

Material damage!

Pressure shocks may occur if the stop valve is opened 
or closed quickly.

•  Always open and close the stop valves slowly and in a 

controlled way.

8.1  Installation

All screw fittings must be checked and tightened if 
necessary prior to installation and commissioning!  
For the torques of the fitting see „5 Technical data“ on 
page 4�

WARNING

Hot water!

Risk of severe scalding.
Do not reach into the hot water when emptying the 

FRG3015-F RV. Ensure that the FRG3015-F RV has 

cooled down before carrying out maintenance, cleaning 

and repair work.

During installation it must be ensured that:
•  the cables from the pump and temperature limiter 

are not damaged or kinked 

•  the sensor capillary tube is not damaged or kinked
•  The cables must not be under tension�

1.  Fit the control station to the manifold with the 1" nuts and 

associated seals. 

The control station can be fitted on the right or left of 
the manifold by turning the eccentric screw fitting (5, 
Fig� 8-1), also upside down�

2.  Fit the temperature limiter to the supply collector pipe on 

the manifold.

3.  Connect the control station to the power supply.

Further information about electrical connection of the 
control station can be found in the separate documen-
tation for the assemblies�

4.  Set the temperature on the (optional) temperature limiter 

to approx. 55 °C.

NOTICE

To ensure that the pump runs only when

heat is required, the manufacturer recommends con-
necting the pump to a pump relay (e.g. the pump logic 
of an electrical control distributor that also controls the 
actuators). Alternatively, the pump can be operated with 
a timer switch. 

8.2  Temperature limiter

In the event of a fault, the temperature limiter switch-
es off the circulation pump and so avoids overheating 
of the surface heating system�

•  The temperature limiter must be fitted to the supply of the 

heating circuit manifold.

•  Set the temperature on the (optional) temperature limiter to 

approx. 55 °C.

8.3  Initial commissioning

All screw fittings must be checked and tightened if 
necessary prior to installation and commissioning!

Torques of the fittings:

¾" fittings: 35 Nm
1" fittings: 55 Nm

1.  Connect the control station to the pipe network.
2.  Fill, flush and vent the heating system.

The non-return valves (4 and 8, Fig� 3-1) in the mixer 
bypass prevents any short circuit when flushing�

NOTICE

Flushing is permitted only in the direction

of flow of the heating circuits, i.e. the water must enter 
through the flow manifold and come out of the return! 
The drain must always be open, as otherwise the high 
water pressure could damage the heating system.  
The instructions on flushing in the operating manual for 
the heating circuit manifold must also be observed.
