Installation and

Operating Instructions

WARNING: Failure to follow these instructions and comply with all applicable
codes may cause serious bodily injury and/or property damage.

The installation of this product should be carried out by a person knowledgable
in swimming pool plumbing requirements following the installation instructions
provided in this manual.

Please pass these instructions on to the operator of this equipment.

Function

The lter uses special lter sand to remove dirt particles from pool water. The
lter sand is loaded into the lter tank and functions as the permanent dirt
removing media.

When the control valve is in the FILTER position, the pool water which
contains suspended dirt particles, is pumped through your piping system and
is automatically directed by the patented lter control valve to the top of the
lter tank.

As the pool water is pumped through the lter, dirt particles are trapped
by the sand bed, and ltered out. The cleaned pool water is returned from
the bottom of the lter tank, through the control valve and back to the pool

through the piping system.

This entire sequence is continuous and automatic and provides for total
recirculation of pool water through your lter and piping system.

After a period of time, the accumulated dirt in the lter causes a resistance
to ow, so the ow diminishes. This means it is time to clean your lter. With
the control valve in the BACKWASH position, the water ow is automatically
reversed through the lter so that it is directed to the bottom of the tank,
up through the sand, ushing the previously trapped dirt and debris out the
waste line. Once the lter is back-washed of dirt, set control valve to RINSE
position and run pump for about 30 seconds to 1 minute, and then to FILTER
to resume normal ltering.

IMPORTANT: Turn pump off before changing valve position.

Installation

Only simple tools (screwdriver and wrenches), plus pipe sealant for plastic
adapters, are required to install and service the lter.

1. The lter should be placed on a level concrete slab, very rm ground, or
equivalent. Position the lter so that the piping connections, control valve
are convenient and accessible for operation and service.

2. Loading the sand media. Filter sand media is loaded through the top
opening of the lter.

a. Loosen ange clamp and remove lter control valve (if previously

installed).

b. Cap internal pipe with plastic cap to prevent sand from entering it.

c. We recommend lling tank approximately 1/2 way with water to provide

a cushion effect when the lter sand is poured in. This helps protect the
under-drain laterals from excessive shock.

d. Carefully pour in correct amount and grade of lter sand. (Be sure centre

pipe remains centred in opening). Sand surface should be leveled and
should come to about the middle of the lter tank. Remove plastic cap

from internal pipe.

3. Assemble lter control valve to lter tank.

a. Insert lter control valve (with Oring in place) into the tank neck, taking

care that the centre pipe slips into the hole in the bottom of the valve.

b. Place two plastic clamps around valve ange and tighten just enough so

that the valve may be rotated on tank for nal positioning.

c. Carefully screw pressure gauge (with Oring in place) into tapped hole in

valve body. Do not over-tighten.
IMPORTANT! Nipple must be pierced for correct operation of gauge.
Ensure gauge is mounted with nipple at TOP. Failure to comply will
VOID WARRANTY.

d. Connect pump to control valve opening marked PUMP. After connections

are made, tighten valve ange clamps with screwdriver, tapping around
clamp with screwdriver handle to help seat valve ange clamp.

4. Make return to pool pipe connection to control valve opening marked
RETURN and complete other necessary plumbing connections, suction
lines to pump, waste etc.

5. Make electrical connections to pump per pump instructions.

6. To prevent water leakage, be sure all pipe connections are tight.

WARNING

This lter operates under high pressure. When any part of the circulating
system (eg. clamp, pump, lter, valves etc.) is serviced, air can enter the
system and become pressurised. Pressurised air can cause the lid or valve
to be blown off which can result in severe injury, death or property damage.

Turn pump off before changing valve position.

To prevent damage to the pump and for proper operation of the system,
clean pump strainer and skimmer baskets regularly.

DO NOT unscrew screws of ange clamp while pump is running.
