SAND FILTRATION WORKING PRINCIPLE
Incoming water from the piping system is automatically directed by the multi-port valve to the top of the
filter bed. As the water is pumped through the filter sand, dirt and debris are trapped by the filter bed, and
filtered out. The filter water is returned from the bottom of the filter tank., through the multi-port and back
through the piping system .
PREPARATION BEFORE INSTALLATION
1. Position the filter as close to the swimming pool / spa as possible.
2. The filter should be placed on a level concrete slab, very firm ground, or equivalent. Ensure that the
ground will not subside to prevent any strain to the attached plumbing.
3. Position the filter so that the piping connections, Multi-Port Valve and winter drain is convenient and
accessible for operation, servicing and winterizing.
4. Ensure that the compliance label is facing the front to allow easy identification in the case of
service difficulties.
INSTALLATION
WARNING:
This product should be installed and serviced only by a qualified professional.
1. Put the filter tank on the base. Turn the filter tank to the right to tighten it. Position the outlet drain plug
so it is facing outside for easy operation.
2. Before filling the filter media into the filter vessel, do a visual check of the laterals. Look for broken or
loose laterals. Replace if necessary. The laterals of side-mount valve sand filter are all installed.
3. Match the Raised Point of the laterals to Folding Umbrella lateral holder, insert the laterals and turn
90º clockwise. Listen for a sound to confirm the lateral is in place.
4. Make sure the air release hose is running along side the body of the lateral holder. One end of the
air release hose
MUST
be out of the sand.
DO NOT
bury the air release hose in the sand.
5. To eliminate stress on the laterals, fill the filter vessel with enough water to provide a cushioning
effect when the filter sand is poured in.
6. Use Sand Shield to protect the filter top mount and make sure the central stem pipe has been fully
covered.
7. Carefully pour the exact amount of sand into the filter vessel.
DO NOT
allow sand to go into the stem
pipe.
DO NOT
damage the filter top mount or it can cause a leak.
8. Put the O-Ring on the top mount valve and then connect the valve on the filter vessel. The
stem pipe should be straight and aligned with the top mount valve. Tighten the flange clamp on the
valve.
NOTE
: The flange clamp should be in place and tight or it could cause injuries.
9. To connect the pump to the base, use the screws from the pump hardware pack.
10. Adjust the valve position. The pressure hose connects to the pump output/input valve.
11. The other two connection ends of the valve connect to the swimming pool and the drain outlet hose.
