5. Remove the Stand Pipe Blocker and clean the
Sand Tank neck carefully.
6. Connect the Multi-Port Valve to the Sand Tank by
using the O-Ring and the Flange Clamp Set.
Note
:
the direction of PUMP port on valve needs to face
pump out port.
7. Connect the Sand Tank to the Pump with Hose,
Hose Clamps and Hose Adaptors.
Plumbing
1. Make sure the filter is worked under the work
pressure and using a pressure control valve when
the system is using a booster pump.
2. If the pump position is higher than the water level,
it requires to install the back water control valve.
3. If the pump position is lower than the water level,
it requires installing an isolation valve. It could stop
the water return back when people do the general
inspection.
4. Minimize the length of pipe and the number of
fittings to minimize friction loss to ensure maximum
efficiency.
5. Connect all plumbing to the Multi-Port Valve taking
care that all joints are glued or tightened securely
to prevent leaking.
6. To prevent breakage and damage to the pump and
Multi-Port Valve, use only pipe sealants specifically
formulated for plastics.
7. Ensure solvents are not excessively applied to
fittings as this could run into O-Rings and create
sealing problems.
8. Do not over tighten fittings or adapters.
CHAPTER 3
: MULTI-PORT VALVE OPERATION
1.
Filter
: Position for filtering the body of water.
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 filtered water is
returned from the bottom of the filter tank, through
the Multi-Port Valve and back through the piping
system.
2.
Backwash
: Position for cleaning the filter media.
Water flow is reversed by the Multi-Port Valve
through the filter bed so that water flow is directed
to the bottom of the tank and up through the filter
bed, flushing the previously trapped dirt and debris
out the waste line.
3.
Rinse
: Position for flushing the filter system.
The water flow is directed by the Multi-Port Valve
through the filter bed and out the waste line. This
process settles the filter media bed into place and
ensures any dirt or debris is rinsed out of the filter,
preventing possible return to the Swimming Pool or Spa.
4.
Waste
: Position for bypassing the filter bed to
Waste. The water flow is directed by the Multi-Port
Valve straight to the backwash outlet, bypassing the
entire filter bed. This Multi-Port Valve position is used
to lower the water level or for vacuuming water with
high dirt loads.
