INSTALLATION 

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

1.  The filter system should be installed, not more than 6 feet 

above pool water level, on 

a level 

concrete slab, very firm 

ground, or equivalent, as recommended by your pool 
dealer. Position the filter so that the piping connections, 
control valve and winter drain are convenient and 
accessible for operation, service and winterizing. 

2.  Assemble pump and pump mounting base, to the filter 

according to instructions packed with the base.  

3.  Loading  sand  media.  Filter  sand  media  is  loaded  through 

the top opening of the filter. 

a.  Loosen flange clamp and remove Filter Control Valve (if 

previously installed). 

b.  Cap internal pipe with sand shield to prevent sand from 

entering it. Be sure pipe is securely in place in bottom 
underdrain hub. 

c.  We recommend filling tank approximately 1/2 way with 

water to provide a cushioning effect when the filter sand 
is poured in. This helps protect the underdrain laterals 
from excessive shock. (Be sure the winter drain cap is 
securely in place on drain pipe). 

NOTE: Check to confirm all laterals are in the 
down position before loading with sand. (See 
Figure A.) 

d.  Carefully pour in correct amount and grade of filter 

sand, as specified. (Be sure center pipe remains 
centered in opening). Sand surface should be leveled 
and should come to within 6" of the top of the filter tank. 
Remove sand shield from internal pipe. 

4. Assemble Filter Control Valve to filter tank. 
a. Loosely pre-assemble both halves of the clamp with one 

screw and one nut, turning the nut 2 or 3 turns. Do not 
tighten. Wipe filter flange clean. 

b. Insert Filter Control Valve (with valve/flange O-ring in 

place) into the tank neck, taking care that the center pipe 
slips into the hole in the bottom of the valve. Install clamp 
around tank and valve flange and assemble second screw 
and nut. Tighten just enough so that the valve may be 
rotated on tank for final positioning. 

c.  Carefully screw pressure gauge, with pipe tape, into 

1/4"NPT tapped hole in valve body. Do not over tighten. 

d. Wrap two turns of Teflon pipe sealant tape manufactured 

for plastic pipe, on the Straight adapter (12 on Fig B) and 
the Elbow adapter (11), starting in the clockwise 
direction at the first full thread with a half width overlap 
for the full effective thread length. 

e. Carefully start the threaded Straight adapter (12) into the 

pump (16) discharge (Top Port) and hand tighten.  
Further tightening may not be needed to make a leak-
proof joint.  However, never tighten more than ½ to 1 ½ 
turns past hand tight to avoid failure due to over 
tightening the joint. 

f.  Carefully start the threaded Elbow adapter (11) into the 

Control Valve (1) port marked PUMP and hand tighten.  
Further tightening may not be needed to make a leak-
proof joint.  However, never tighten more than ½ to 1 ½ 
turns past hand tight to avoid failure due to over 
tightening the joint. 

g. 

Place two hose clamps (14) over clear hose (13).  Fit 
hose over straight and elbow adapters and secure with 
the clamps.  (HINT: If it is difficult to fit hose over 
adapters, place hose in hot water for several minutes.  
Be Careful HOT WATER can burn you).  After the hose 
connections are made, tighten valve flange clamp with 
screwdriver, tapping around clamp with screwdriver 
handle to help seat valve flange clamp.  Please be sure 
to place the vinyl protector caps over the ends of the 
screws.

 

5.  Make return to pool pipe connection to control valve 

opening marked RETURN and complete other necessary 
plumbing connections, suction lines to pump, waste, etc. 

6. Make electrical connections to pump per Pump Owners 

Guide instructions. 

7. To prevent water leakage, be sure winter drain cap is 

securely in place and all pipe connections are tight. 

 

INITIAL START-UP OF FILTER 

1.  Be sure correct amount of filter sand media is in tank and 

that all connections have been made and are secure. 

2.  Depress Vari-Flo control valve handle and rotate to 

BACKWASH* position. (To prevent damage to control valve 
seal, always depress handle before turning.) 

3. 

Prime and start pump according to pump instructions (be 

sure all suction and return lines are open), allowing the filter 

tank to fill with water.

 

 

 

WARNING:

 ALL SUCTION AND 

DISCHARGE VALVES MUST BE 
OPEN WHEN STARTING THE 
SYSTEM. FAILURE TO DO SO 
COULD CAUSE SEVERE PERSONAL 

INJURY.

  

 

Once water flow is steady out the waste line, run the pump for 
at least 2 minutes. The initial back-washing of the filter is 
recommended to remove any impurities or fine sand particles 
in the sand media. 
4.  Turn pump off and set valve to RINSE position. Start pump 

and operate until water in sight glass is clear

—about 1/2 to 1 

minute. Turn pump off, set valve to FILTER position and 
restart pump. Your filter is now operating in the normal filter 
mode, filtering particles from the pool water. 

5.  Adjust pool suction and return valves to achieve desired 

flow. Check system and filter for water leaks and tighten 
connections, bolts, nuts, as required. 

6. 

Note the initial pressure gauge reading when the filter is 

clean. (It will vary from pool to pool depending upon the 
pump and general piping system). As the filter removes dirt 
and impurities from the pool water, the accumulation in the 
filter will cause the pressure to rise and flow to diminish. 
When the pressure gauge reading is 8-10 PSI (0.55-0.69 
BAR) higher than the initial "clean" pressure you noted, it is 
time to backwash (clean) the filter (see BACKWASH under 
Filter Control Valve Functions.)

 

NOTE: During initial clean-up of the pool water it 
may be necessary to backwash frequently due to the 
unusually heavy initial dirt load in the water.
