Installation

General Notes
1. When unpacking the filter, be sure the unit is complete and no visible shipping
damage has occurred.
2. Allow sufficient clearance around filter system for access and maintenance.
3. Provide adequate ventilation for pumping equipment, installed in conjunction with
filter.
4. Provide solid mounting for filter and pump. If installed outdoors, install the sys-
tem on a slab or solid concrete base to avoid risk of settlement. Filter systems
once located with sand and water can exceed a weight of 250 kg. If installed in-
doors, ensure doorway allows sufficient clearance should filter tank require re-
placing.
5. Installation of filters and pumps should be located as close to the pool as possible
to avoid excessive piping friction loss.
6. If system is installed below pool level it is important to install isolating valves to
prevent risk of flooding from back up water, from the pool or spa.
7. The proper sand selection is critical to good filter performance. Ensure that the
media is an approved form of Quartz Silica sand, glass or Zeolite.
8. The installation of filters requires no special tools.
9. Confirm that plumbing lines from pool are correctly identified. This will ensure
proper connection to markings on filter valve (i.e. "Pump", "Waste", and "Re-
turn").
Loading Sand Filter
Once the filter system has been positioned, the installation of filter sand may be un-
dertaken as follows:
1. Check filter size in order to determine necessary amount of sand required.
2. Double check that the internal system consisting of a lateral hub and stand pipe
are intact inside the tank.
3. Fill tank half full with water.
4. Place the disposable loading disc into the upper tank opening and the plastic
cover over stand pipe to stabilise the filter and stand pipe. It is important that the
stand pipe remains centred through the sand loading procedure to ensure align-
ment with valve assembly opening.
