Water Inlet; Water Outlet; Overflow - Theiling ROLLERMAT XC Operation Manual

Water inlet

1. Water inlet by Gravity
If operated by gravity, the Rollermat is placed below the aquarium or below the water
level of the pond in the filter sump.
From the overflow chamber of the aquarium or from the skimmer of the pond a pipe
with a diameter of 63 mm is connected to the water inlet of the Rollermat (1).
It is important, that the 63 mm pipe is just pressed into the tank union. If it is glued, it the
Rollermat cannot be disassembled for maintenance.

Water outlet

The water outlet may not be reduced. A 90 mm PVC pipe should be presses into the tank
union. From here a PVC pipe can be directed to the filter sump or pond. The pipe should not
be glued into the tank union. If it is glued, the Rollermat cannot not be disassembled.
Alternatively a 90 mm hose fitting can be pressed into the tank union and a hose may be
directed to the pond or aquarium.
In any case, the water must flow freely away from the outlet. Neither a PVC pipe nor a
flexible hose may be directed higher than the outlet of the Rollermat.

Overflow

The emergency overflow is a 40mm tank union. Here, you can press in a 40 mm PVC pipe.
From here the pipe is directed downwards in a free flow pipe. Alternatively a 40 mm hose
connection can be pressed into the tank union and a hose can be directed to the pond or
aquarium.
2. Water inlet by pump pressure.
If the Rollermat is supplied with water by a pump, the
maximum flow is 10.000l/h (e.g. River 8.000). The water
inlet has to be reduced by a reduction fitting to a 1.5" hose
connector. This connections should be glued.
The Rollermat is placed above the water level of the
aquarium or pond. The water flows back by gravity into the
aquarium or the pond.
