INSTALLATION INSTRUCTIONS
SE FLOWSTAR PUMP STATION - 221337
» After commissioning, fi ll in the log on the last
page of this manual.
» Hand the manual over to the end user. Instruct
the end user to keep the manual in close
proximity to the system.
» Instruct the end user to have the solar station
serviced and repaired by a specialist only. The
controller settings must not be changed by the
end
user.
» Explain to the end user the function of the system
and of the safety devices. Point out to the end
user that the shell must remain mounted during
operation and that the check valve with temperature
gauge and the ball valve in the fl owmeter must be
open.
1.5 General safety instructions
Before installing and commissioning the product, you must
read and observe the following safety instructions:
A. Danger of scalding due to escaping vapor
If the system pressure is too high, hot solar fl uid will escape
from the pressure relief valves and can result in scalding.
Flush and fl l the system only if the collector temperatures
are below 150F (70C).
Connect a discharge line to the safety assembly. Observe the
instructions regarding the pressure relief valve.
B. Risk of burns
The valves, fi ttings and the pump may heat up to more
than 212 °F (100 °C) during operation.
C. Personal injry and material damage caused by excess
pressure
Closing the ball valves both in the return and supply line of
the solar circuit, will disconnect the safety assembly from
the heat exchanger. Heating the storage tank can result in
the formation of high pressures, which may lead to material
damage and personal injury.
In operation, the ball valve with temperature gauge and the
ball valve at the fl owmeter must always be open.
Close the ball valve only when service is required.
1.6 General instructions regarding solar fl uid
Propylene glycol is hazardous in the case of ingestion. It is
an irritant when it comes into contact witht he eyes or skin.
Always wear chemically resistant protective gloves and
safety glasses with side-shields when handling propylene
glycol mixtures.
1.7 Frost damage
Observe the instructions and specifi cations of the antifreeze
from the manufacturer.
It often happens that solar thermal systems cannot be
completely drained after fl ushing. Thus, there is a risk of
frost damage when fl ushing with water. Therefore, the solar
thermal system should only be fl ushed and fi lled with the
solar fl uid used later on.
Strictly follow the instructions of the antifreeze manufacturer
for operating a solar thermal system. All components in
the solar station are resistant to a percentage of propylene
glycol of up to 50%.
Determine quantity according to system volume. See
instructions of the collectors, storage tank and expansion
tank.
2 Description of the product
This solar pump station is designed to be mounted in one
of two ways. Both mounting options are discussed in the
manual. It can be mounted either on a wall support and
held by clip springs, or on a Stiebel Eltron solar storage tank
using a tank mounting kit.
