This lter is designed for use in domestic/residential swimming pool installations with
correctly sanitised fresh or salt chlorinated water. Suitable for use with sand or Zelbrite
lter media.
1. Locate the lter system as close to the pool as practical.
2. Place the lter on a level stable foundation, preferably a concrete pad or paving.
3. Position all equipment to provide ease of access for future
servicing.
4. Protect the lter and pump from weather and direct sunlight by
ensuring that they are properly housed.
5. Ensure there is sucient space to provide adequate ventilation to
electric pump motor.
6. Clean a new pool as well as possible before lling pool and
operating lter. Excess dirt and large particles of foreign matter in the system can
cause serious damage to the lter and pump.
7. Ensure pump is compatible with lter specications.

INSTALLATION & ASSEMBLY
Hazardous Pressure
Incorrectly installed or tested equipment may fail, causing severe injury
or property damage. Read and follow instructions in owner’s manual when
installing and operating equipment.
Have a trained pool professional perform all pressure tests.
All glued ttings and pipe work should be allowed to dry to atmosphere for
24 hours before closing the installation. Failure to do so could cause injury
or installation failure.
The ttings on these lters are constructed of ABS. Some PVC jointing
compounds are incompatible with ABS possibly causing failure to the
product. Check compound suitability prior to use.
WARNING
HAZARDOUS Pressure!
Can cause severe injury
or major property damage
from tank explosion.
Filter pumps require
hazardous voltage which
can cause shock, burn or
even death.
Disconnect power to
motor.
1. Stop pump.
2. Release all pressure
from system by turning
valve handle to waste.

INSTALLATION & ASSEMBLY
Installation & Assembly of Internal Components
Installation of lter should be only carried out by qualied personnel. Ensure that the
under-drain assembly (hub, laterals & tube) are properly assembled & installed prior to
adding lter media (sand).
1. The lter internals comprise of a collector hub and eight (8) laterals,
which are supplied packaged seperately with the collector hub and are stored inside
the lter tank prior to shipment.
2. Carefully inspect the laterals and hub prior to assembly for any
visible defects.
3. To assemble the laterals and hub please use the following steps. (The connection
between the hub and the lateral is completed inside the lter tank - refer to diagram
on following page)
For P221100 & P225100 Models only:
Push in and align the male tab on the lateral with the female slot in the hub. Rotate the
lateral clockwise until the tabs engage with an audible “click”. Repeat this process for all 8
laterals.
For P229200 & P233200 Models only:
Place the hub inside the neck of the lter tank. Begin by assembling the ‘F’ pieces, align
the lateral key with the hub and insert, turn to lock in place. Repeat with the 4 ‘F’ pieces.
Next, insert the large diameter laterals in the outer socket of the ‘F’ pieces. Repeat 4
times. Finally, insert the small laterals into the inner sockets. Repeat 4 times.

B. Insert assembly into
top of lter tank.
C. Hold assembly up near top
of tank and add remaining
laterals.
D. After all laterals
are securely
in sockets,

Loading Sand Media
1. To keep sand out off collector assembly, place
plastic sand shield over top of collector tube before
pouring sand into lter (See diagram).
2. To support laterals and prevent lateral breakage
during loadings, ll tank about half full of water
before loading sand.
3. Pour sand into lter, making sure that the sand is of
the correct type and quantity for the particular lter
model (Refer to lter label).
INSTALLATION & ASSEMBLY
Make sure gasket area on top of tank is free of
sand before installing valve.
4. Before installing valve, double-check that the correct quantity of sand has been
loaded.
5. Remove plastic sand loading shield and keep for future use.
Installation of Multi-Port Valve
1. Install o-ring on valve ange; make sure o-ring is clean, and has no nicks, tears, or
scrapes and lubricate with silicon based lubricant.
2. Make sure tank and valve anges are clean and free of sand; put valve on top of tank.
Vertical pipe of collector assembly inserts into base of valve.
3. Install clamp; make sure knob is positioned for easy access for lter maintenance.
Valve port labelled “Pump” should point toward pump.

4. Tighten clamp knob until clamp ends (under bolt) are 1/4” (6mm) apart.
Tap around outside of clamp with a mallet to help seat clamp.
5. Connect pipe from pump discharge to valve port labelled “PUMP”; use union half
provided. Assemble union as follows for leak free operation:
- o-ring and sealing surfaces must be clean.
- Assemble hand tight only (No wrenches).
- NO pipe compound or teon tape on unions.
6. Complete all plumbing connections, using 1 1/2” (P221100 & P225100) or 2” (P229200
& P233200) pipe to reduce pressure losses as much as possible.
- Pipe from valve RETURN port to pool return.
- Pipe from valve WASTE port to waste.
- Suction piping from pool to trap inlet on pump.
7. System is ready to start up.
8. If you notice a leak around the clamp area after
15-30 minutes of running, repeat steps 3-4.
Hazardous pressure. Clamp will not hold unless it is
seated properly! DO NOT START PUMP until clamp ends
are 1/4” (6mm) apart or less.
INSTALLATION & ASSEMBLY
If there are leaks from beneath valve/
clamp area, STOP PUMP, release all
pressure by turning valve handle to
‘waste’, remove clamp and valve and
clean sealing surfaces.
