11.0 Connection of Drain Pipe
The unit needs a drain pipe to function correctly.
Remove the lid via the screws and decide which side the
drain pipe is to be connected. On the same side as where
the drain pipe is to be connected, fit a 135 degree elbow to
the copper pipe and connect a 22mm dia. plastic pipe to the
other side of the elbow and through the supplied “O” ring in
the outer wall. This is the drain pipe.
Seal the internal perimeter between the drain pipe and “O”
ring with silicone to prevent air leakage.
On the other copper pipe place the end stop as shown in
the diagram below and place the supplied rubber bung into
the opposite hole in the outer casing to prevent air leakage.
Replace the lid and hand tighten all the fixing screws.
