Halsted Rain Frogmouth Filter User manual

Page 1
Important Information:
These instructions and dimensions are provided for guidance only. They may require
adapting to individual site requirements and the design of the tank system.
When the filter is installed to provide the tank overflow, the rainwater divert and overflow
pipe must be horizontal and level.
If the downpipe is over 4 m to Frogmouth entry, install an elbow entry to reduce the velocity
of rainwater flowing from the roof line.
It is recommended that the push fit adaptors are secured with PVC cement/glue or a screw
fixing. The adaptors can be painted to match the colour of the downpipe. They should be
washed in soapy water and prepared with a primer coat before painting.
