CONNECTIONTOTHE AQUARIUM WATER SUPPLY
Water flow:
There is no correct flow direction through the unit. Either port
may be used as the inlet or outlet.
Connection with flexible hose
The V

diameter flexible hose. If you are using one of the three larger sizes, the smaller
sections of the hosetails must be cut off to ensure sufficient water flow and to
prevent possible damage to the pump. We recommend that you use the largest
diameter hose available. As it is easier to cut the hosetails while they are attached to
the unit, attach them using the female threaded lock nuts and gaskets provided. Ensure
that the gaskets are seated correctly between the flat face of the hosetails and the flat
face of the inlet/outlet ports. Using a hacksaw, carefully cut off the excess hosetail,
ensuring that the sections are cut off at the second ridge and that the cut follows the
line of the ridge.
Once trimmed, hand tighten the lock nuts to secure the hosetails to the inlet/outlet ports.
Do not use jointing compound or PTFE tape. Secure the hosepipe to the hosetail
with a stainless steel hose clip.
The hosetails supplied are made from a translucent material which will glow when the
unit is operating correctly. (NB. glow only visible in low levels of light.)
Connection using rigid pipe
This unit may also be rigid plumbed in either of the following ways:-
1.
Using TMC universal rigid pipe adaptors
available from your aquatic
supplier (part no. PCADRPACTO4)
.
These should be fitted as shown in the diagram below.
A. If using 40mm solvent weld plastic pipe the adaptor will be glued into the
pipe. It is essential to fit the lock nut before you solvent weld the adaptor
into the 40mm pipe. When solvent welding the two parts, sufficient space
(20mm as shown) must be left between the adaptor and the 40mm pipe
to allow the lock nut to be undone.
B. If using 1” solvent weld pipe the pipe will be glued into the adaptor at the
first stepped stage.
C. If using 32mm solvent weld pipe the pipe will be glued into the adaptor at
the second stepped stage.
Important:
Once you have solvent welded the two parts they must be left to
fully cure before making the final connection between the rigid pipe adaptor
and the V
2
ecton. When attaching the plumbed rigid adaptors to the unit ensure
that the gaskets are seated correctly between the flat face of the pipe adaptor
and the flat face of the inlet/outlet ports. Do not use a jointing compound or
PTFE tape.
For USA rigid plumbing you should use the 1” pipe option above.
