Page 3: Safety Instructions
Safety instructions These instructions are intended exclusively for authorised profes- sionals. To avoid accidents and damage due to incorrect operation, carefully read through these operating instructions before you start working with the freshwater station. If you carry out any alterations to the construction of the freshwater station or the safety devices, you may invalidate your right to make guarantee claims. -
Page 4: Mode Of Operation
The cooled tank water is returned to bottom layer of the buffer tank. The speed control of the primary circuit pump takes place in the FRISTAR controller based on the measurements of the volume flow sensor in the hot water pipe (temperature T... -

Page 6: Installation
If the tank is operated at a temperature higher than 70°C a pre-mixer that restricts the tem- perature to less than 70°C must be used in the primary circuit. The VMS pre-mixing set is suitable for both Fristar models (left pump, right pump). Figure: Connection for Fristar with right pump Thread 3/4“... -

Installation Mounting position: Only vertical Pull off the cowling in a forwards direction. If necessary: Interchange the right/left connections (see chapter "Interchanging con- nections"). Mark the fastening points, insert rawlplugs, fasten the station to the wall. Fitting and connection of the pipe connections (3/4" outside thread connector). Plan for as short as possible pipes in the primary circuit (tank ->... -

Page 9: Connection Of A Circulation Line
Connection of a circulation line The plate heat exchanger is provided with a connection for a circulation line. To lead the circulation line through to the heat exchanger, the isolation cap must be cut out to suitable dimensions.

Page 10: Interchanging Connections
Interchanging connections For optimum matching of the pipelines to the freshwater station it is possible to interchange the connections (right/left). Doing this does not change the circulation line heat exchanger openings or the venting of the primary circuit. Version Version "Pump right"... -
Page 11: Cascade Switching
Cascade switching At most, a maximum of 4 FRISTAR fresh water stations may be used in parallel in cascade switching. The first module is fed directly, all others stations are added with stop valves, if necessary. These valves must open or close in at least 30 seconds. -
Page 12: Cascade Switching Control With Uvr61-3R Or Uvr63
Cascade switching control with UVR61-3R or UVR63 Controllers UVR61-3R and UVR63 have exactly the same settings. Step-by-step instructions for UVR61-3R: Menu Access to menu Men with Code 64, to menu Par with ENTER Code 32. Adoption of the volume flow on sensor FTS9-150DL as EXT DL external sensor E1. -
Page 13: Control Of Cascade Switching With Uvr1611
Figure with fresh water stations version, version “Pump on the right“ Circulation pump The circulation pump is connected only to the always ready FRISTAR 1 and must not gener- ate a flow larger than 18 l/min. If the system is to be switched via UVR61-3R or UVR63, three FRISTAR modules at most are possible. -
Page 14: Circulation Pump (Optional)
Circulation pump (optional) If an external circulation pump is connected then it will work in pulse mode. If water is drawn, the circulation pump runs with the run time (20 or 40 seconds) set with the selector switch. After the end of the run time, pump start-up is permitted only after a 10 minutes break. Electrical circuit diagram Plug for volume flow sensor VFS Primary... -
