INSTALLATION INSTRUCTIONS
SE FLOWSTAR PUMP STATION - 221337
Before decommissioning, wait until the solar fl uid has
cooled down below 122F (50C).
6.1 Draining the solar installation
Complete draining allows components in the pump station
to be replaced.
1. Disconnect the controller from the power supply and
secure it against being switched on again.
2. Open the check valve to the 45 position.
3. Connect a heat-resistant hose to the drain valve. Make
sure that the solar fl uid is collected in a heat-resistant
container.
4. Open the drain valve.
5. To accelerate the draining of the solar circuit, open the
bleeding device at the collectors.
6. If discarding the solar fl uid, dispose of it observing any
local regulations.
6.2 Replacing the pump
1. After performing the draining process as in 6.1,
disconnect the pipe joint between the pump station and the
storage tank.
2. Dismount the fl owmeter connection to the pump.
3. Dismount the pump connection from the upper
assembly.
4. Install the new pump, making sure to include new
gaskets.
5. Mount the fl owmeter.
6. Connect the pump station to its original connections.
Repeat the commissioning process as described in section 4.
7 Spare parts
2. Observe the fl ow via the fl owmeter.
2. Re-mount the front shell on the solar station.
3. Set the controller to automatic mode.
5 Cleaning
Clean the pump station only from the outside with a damp
cloth. Never use scouring or sand-containing cleaning
agents.
6 Maintenance and decommissioning
Before maintaining and decommissioning the system, read
and observe the following safety instructions.
A. Risk of electric shock
Disconnect all electrical devices in the solar circuit from
the power supply before carrying out maintenance work or
decimmissioning.
Ensure that the electrical devices cannot be switched on
again.
B. Risk of burns and scalding.
The valves and fi ttings may heat up to more than 212
(100C).
