Gravity Fed Installation Section
IMPORTANT…
For gravity fed installations, you will need to swap pipes
D
and
E
for eachother,
(
no cutting required
) and change the configuration of the inlet, outlet fittings and valves.
The return pipe
D
although crucial for a pump fed system would impede a gravity unit when
slight fouling of debris occurs in the Pod.
1.
Remove the overflow assembly and safely
store the 3 screws which secure it. Fig. 7
2.
Remove the stainless steel perforated pipe
by pulling gently. Fig. 8
3.
Loosen the upper clip on the rubber
connector Fig. 9
Fig. 7 Fig.8
4.
Invert the Pod and remove the 2 screws
and plastic pipe support bracket Fig. 10
5.
Pull the pipe assembly from the Pod body.

NOTE
–
The return pipe
D
is part of a pipe
assembly comprising of a 90 degree elbow
and two lengths of pipe. The return pipe
D
(as delivered), is longer than the outlet pipe
E
.
Turn the assembly around 180 degrees
and replace the shorter length as the return
pipe and the longer length as the exit pipe.
You have now swapped E for D over for
each other.

7. The assembly is refitted by pushing the
shorter pipe through the inverted Pod’s
central exit hole. Fig. 11
8. Tighten up the rubber connector to form
a watertight seal, on the now shorter pipe
D
.

9. Refit the steel pipe with the perforations
at the top,
not
at the bottom. Fig. 13

The Pod must be situated at pond water level. That is to say, that when the circulating pump
is switched off, water is level with the overflow assembly. This level will lower when in
operation. (see Fig. 14)
The 2 rubber connectors on the inlet and outlet ports must be swapped over so that on the
inlet you will have the 4 inch (90-115mm) rubber connector
E
(Fig.1.1) to take your pipe work
from the pond and on the outlet you will have the 1.5 inch (40mm) connector for your return
pressure line.
