Piping
Run discharge tubing to a suitable drain where it is unlikely to freeze during
operation. The highest point of the run must be less than 15m / 49ft above
the pump and not more than 0.3m / 1ft below to avoid siphoning (fig. 7). Ma-
ximum tube length is 100m / 330ft. Take care not to pinch or kink the tubing.
Secure or support the discharge tube to reduce noise. Push the rubber inlet
connector onto the drain hose (fig. 3) or collection tray stub. Secure with the
cable ties provided. Bend into position the breather support wire so tube
end is above collection tray if possible (fig.8).

Inspection and Maintenance
Inspect the filter for sediment and debris. When handling pump during in-
spection and maintenance, keep pump assembly reasonably upright and
level to prevent any water spills from entering the pump. In some instal-
lations it may be possible to service the pump while still attached to the
equipment. If necessary support the pump assembly to prevent excessive
strain on cables and connections. If cleaning is required, disconnect the fil-
ter housing by rotating 80° counter clockwise and carefully separate (fig.9).
Do not use detergents in servicing this product. Using a small tool carefully
lift the filter out of its location and rinse under a tap with clean water. If the
O ring is disturbed, clean O ring and mating surfaces and re-seat (fig.10). In-
