WARNING

 

– To avoid dangerous or fatal electrical shock, turn OFF power to motor before working on electrical connections. 

 

 

WARNING 

– 

Failure to bond pump to pool structure will increase risk for electrocution and could result in injury or death.  To reduce the 

risk of electric shock, see installation instructions and consult a professional electrician on how to bond pump.  Also, contact a licensed 
electrician for information on local electrical codes for bonding requirements.

 

 

 

Your Sand Master Pro Series high-rate sand filter is a high 
performance, totally corrosion-proof filter that blends superior 
flow characteristics and features with ease of operation. It 
represents the very latest in high-rate sand filter technology. It 
is virtually foolproof in design and operation and when 
installed, operated and maintained according to instructions, 
your filter will produce clear, sparkling water with only minimal 
attention and care. 

HOW IT WORKS 

Your filter uses special filter sand to remove dirt particles from 
pool water. Filter sand is loaded into the filter tank and 
functions as the permanent dirt removing media. The pool 
water, which contains suspended dirt particles, is pumped 
through your piping system and is automatically directed by the 
patented filter control valve to the top of the filter tank. As the 
pool water is pumped through the filter sand, dirt particles are 
trapped by the sand bed, and filtered out. The cleaned pool 
water is returned from the bottom of the filter tank, through the 
control valve and back to the pool through the piping system. 
This entire sequence is continuous and automatic and provides 
total recirculation of pool water through your filter and piping 
system.

 

After a period of time, the accumulated dirt in the filter causes 
a resistance to flow, and the flow diminishes. This means it is 
time to clean (backwash) your filter. With the control valve in 
the backwash position, the water flow is automatically reversed 
through the filter so that it is directed to the bottom of the tank, 
up through the sand, flushing the previously trapped dirt and 
debris out the waste line. Once the filter is backwashed 
(cleaned) of dirt, the control valve is manually resequenced to 
Rinse, and then Filter, to resume normal filtering. 

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, No. 

S160TPAK1, or S160TPAK3 (if supplied) 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 on Table 1. (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.  Wrap two turns of Teflon pipe sealant tape manufactured 

for plastic pipe on the ¼” NPT male end of gauge. 
Carefully screw pressure gauge, into 1/4"NPT tapped 
hole in valve body. Do not over tighten. 

d. Connect pump to control valve opening marked PUMP 

according to instructions. After connections are made, 
tighten valve flange clamp with screwdriver, tapping 
around clamp with screwdriver handle to help seat valve 
flange clamp. 

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 instructions. 

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

securely in place and all pipe connections are tight.
