bottom connection on the outlet assembly
using the hosetail and jubilee clip supplied
(
Fig 8A). Remember that the end of this
hose must not be more than one metre
higher than the Saturn Booster.
Filter Bypass Hose:
T
he filter bypass hose must be the same
diameter as your pond pump hose and
connects to the bottom connection on the
i
nlet assembly using the hosetail and jubilee
clip supplied (Fig 8B).
Turning the Saturn Booster on for the first
time
O
nce you have connected the power cable
to your mains electrical supply in accordance
with the Safety and Electrical Instructions
a
bove you are ready to start.
•
Make sure the flush-away handle is
pushed fully down to ensure there isn’t a
leak path out of the flush-away hose.
• Turn on the pond pump. Within a couple
o
f minutes water will start filtering
through the Saturn Booster and into your
filter system.
! If there isn’t any water flowing through
t
o your filter system after a couple of
minutes, double check that the pond
pump is working, and that the Saturn
Booster’s inlet hose is correctly connected
to the top connection on the inlet
assembly.
• Turn on the Saturn Booster power supply.
The Saturn Booster will now backwash
the internal mesh filter removing solid
waste that will settle in the bottom of
the vessel.
• Check that there isn’t any water flowing
from the flush-away hose and filter
bypass hose.
! If water is flowing out of the flush-away
hose check that the flush-away handle is
pushed right down. If water continues to
flow from the hose, raise and lower the
flush-away handle a couple of times in
case some debris is trapped in the valve.
! If water flows out of the filter bypass
hose this is because the pressure in the
Saturn Booster is too high. There are
three possible causes:
1) Your pond pump is delivering too
much flow/pressure. Provided you still
have reasonable flow to your filter
system, this is not a problem, however
fitting a valve in the pond pump hose to
restrict the flow to the Booster will stop
the overpressure valve from operating all
the time (Fig 9).
2) The flow of water from the Saturn
Booster outlet to the pond is being
restricted. Check all hoses between the
Saturn Booster and your filter system are
clear of obstruction. Check that your
filter system is not restricting the flow.
3) The difference in height between the
Saturn Booster and Biofilter is too great.
If your filter system is, for example, at the
top of a waterfall, ideally position the
Saturn Booster at the same height.
• Confirm that the flush-away valve is
working by lifting the flush-away handle
and checking that water flows from the
flush-away hose. If the flow of water
from the hose is a lot less than that
flowing into your filter system, check the
flush-away hose for obstructions and also
double check that it is not raised more
than one metre above the Saturn
Booster.
2. OPERATION AND
MAINTENANCE
O
peration:
F
lushing out waste
A
t least once every week the waste should
be flushed out. This is done by lifting the
flush-away handle (Fig 10). When the flush-
a
way handle is fully-raised, the water flow is
redirected to the flush-away hose.
Usually, all of the waste will be flushed out
within fifteen seconds. This can be
c
onfirmed by looking at the visible portion
of the translucent hosetail and waiting for
the water flowing through the hosetail to
c
lear.
W
hen complete, lower (Fig 11) to redirect
the flow to your filter system. If water
continues to flow from the waste hose, raise
a
nd lower the flush away handle a couple of
times to dislodge any debris that may have
become trapped in the valve.
Pressure Sensitive Relief Valve (Blue)
Depending on the flow rate and debris, the
b
lue valve can move down during normal
operation. This indicates that it is regulating
the pressure. If your installation has a high
level of debris being pumped from your
pond, the blue valve will stay partially open.
In this situation, it is recommended that the
Booster waste is flushed away daily. During
flushing the valve will rise fully, but will fall
partially soon after completion. In these
conditions although the Saturn Booster will
continue to remove high levels of debris,
reducing the flow rate can increase
performance further. With the improved
filtration provided by the Saturn Booster,
reducing the flow rate can often lead to
improved water clarity and quality as a
result of lower flow velocity through the
mechanical filter, increased dwell time for
biological action, and increased exposure to
the UVC (where fitted). Fitting a valve in the
pond pump hose (fig 9) is a simple way to
adjust the flow.
Another cause for high debris levels is if the
in-pond pump is placed on the bottom of a
dirty pond (see point 3 in ‘Installation’).
If the Booster has not been desludged for
some while, and the blue valve has moved
down, raise and lower the flush-away
handle 5 times, leaving it raised for just a
couple of seconds each time before flushing
out all the waste for 15 seconds. This will
ensure that any debris that has built up will
be dislodged and flushed out.
Blanket weed treatment
If you have treated your blanket weed with
a proprietory blanket weed treatment, this
causes the blanket weed to fragment which
can then enter the Booster and block the
mesh filter. To avoid this, remove the
Booster from your filter system and
reconnect your pond pump hose directly to
your filter. The Booster can be re-connected
once the suspended blanket weed has been
removed from your pond. This can take
between 4-6 weeks.
Winter Storage
If the unit is not run all year round, protect
if from frost in the winter by draining and
storing the unit in a dry place.
To drain, pull up the flush handle to empty
some of the water, and then gently tilt the
Saturn Booster until most of the water is
emptied.
Maintenance
The Booster is designed for continuous
operation and should not require any
maintenance.
In the unlikely event that you experience a
problem, please use the ‘check-list’ below to
i
dentify the cause.
ATTENTION
AUTOMATIC CUT-OUT. To help ensure your
Booster’s motor long life and to prevent
d
amage, it is fitted with automatic thermal
o
verload protection. This switches off the
motor if it overheats. If this occurs, switch
off the power at the mains supply to the
motor. Check for the cause. Usually it will be
due to no water flow through the Booster.
C
heck that the pond pump is running
c
orrectly and water is flowing through your
filter system. Wait 15 minutes for the motor
to cool down and automatically reset. Then
switch on the mains supply to the motor. If
the problem persists, there is a problem with
t
he motor and should be investigated
f
ollowing the same sequence as if the blue
filter valve is staying down.
The valves on the inlet assembly can be used
t
o help determine the problem. The filter
bypass valve is red, and in normal operation
the valve is fully down, and can not be seen
through the clear cap. The pressure sensitive
relief valve is blue, and in normal operation
should still be high enough to be seen
through the translucent blue cap (Fig 24).
Note: The two caps are different in design
and must be replaced with the identical part
i.e. blue cap to blue valve and clear cap to
red valve. The caps use a bayonet lock
system. To remove a cap use the spanner
provided (‘A’ Fig 1). Turn the cap
approximately 20º anti-clockwise, lift up
slightly, and then turn clockwise to remove
(Fig 23).
Possible Problems:
If the blue Filter valve stays fully down
(permanently), and very little waste is being
flushed out, it is likely that the backwashing
has become ineffective and the mesh filter
has become blocked:
• Check the power supply to the Saturn
Booster. If this is OK:
• Turn off the pond pump and the power
supply (to the Saturn Booster)
• Firstly, check that the blue valve is clear
of debris by removing the blue cap. If
debris is holding the valve open, remove
it and re-test for correct operation. If
there is still a problem carry out the
following checks.
• Remove the Saturn Booster’s lid by
undoing the eight bolts with t he Allen
key supplied (Fig 12).
• Turn on the Booster power supply. Water
should flow from both ends of the cream
rotor causing the rotor to rotate.
• If there isn’t any water flowing out of
the ends of the rotor, the backwashing
pump is defective and needs replacing
(see ‘Replacing Pump’).
• If water is flowing out of the ends of the
rotor but the rotor isn’t rotating, the
rotor may have become partially blocked
and will need to be stripped down to
clear the blockage (see ‘Unblocking
Rotor’).
• If everything appears in order, then clean
the parts using a garden hose to remove
any debris and reassemble.
If the red valve is up and water flows back
into the pond through the filter bypass
