The filter should never be buried at a depth over 48". If the filter must be placed below
ground deeper than 48", it will be necessary to place the filter in a vault. Placing the filter
more than 48" below ground without a vault could compromise the structural integrity of the
filter housing.

Maintenance:
The housing of the RH9521-12 is maintenance-free. It consists of non-corrosive plastic. The filter
mesh is virtually self-cleaning by the action of water flowing over the vertical mesh. Nevertheless, a
thin film will build up on the mesh over a period of time. Usually this does not effect the efficiency of
the appliance, but we recommend taking out the filter insert from time to time and spraying any
openings that have become clogged from the inside with a strong jet of water (garden spray or
high-pressure cleaner). Cleaning can also he carried out by hand using a small brush (not a wire
brush) and normal dishwashing liquid.
Removing The Filter:
• Lower the filter handle onto the top of the
filter, position the flat part under the lugs
and lift the filter out.
• Do not leave the filter handle attached after
use. It will impede the water flow and lower
the efficiency of the filter.
