WARNINGS AND IMPORTANT SAFETY PRECAUTIONS

Pump and DE Element Filter System Installation and User’s Guide
A pool or spa pump must be installed by a qualified pool and spa
service professional in accordance with the National Electrical Code and all
applicable local codes and ordinances. Improper installation may create an electrical hazard which
could result in death or serious injury to pool users, installers, or others due to electrical shock, and
may also cause damage to property.
ii
WARNINGS AND IMPORTANT SAFETY PRECAUTIONS
High Pressure from the DE element filter can cause severe injury or
major property damage due to tank separation.
Release all pressure and read instructions before working on the
DE element filter. If the filter lock ring is adjusted under pressure,
the tank can separate, causing serious injury or major property
damage.
Pumps improperly sized or installed or used in applications other
than for which the pump was intended can result in serious personal injury or
death. These risks may include but not be limited to electric shock, fire, flooding, suction
entrapment or serious injury or property damage caused by a structural failure of the pump or
other system component.
Never exceed the maximum stated pump flow rating.
Only use a pumping system rated for the corresponding flow. FAILURE TO DO SO
CAN RESULT IN HAIR OR BODY ENTRAPMENT WHICH CAN CAUSE SERIOUS
PERSONAL INJURY OR DEATH. If in doubt about the rating of your system, consult
a qualified pool service professional.
Pumps are not a substitute for properly installed and secured pool drain
covers. An ANSI/ASME A112.19.8 approved anti-entrapment drain
cover must be used for each drain. Pools and spas should utilize a minimum of two drains
per pump. Regularly inspect all covers for cracks, damage and advanced weathering. If
a cover becomes loose, cracked, damaged, broken or is missing, close the pool or spa
immediately, shut off the pump, post a notice and keep the pool or spa closed until an
appropriate VGB 2008 certified cover is properly installed. Covers deteriorate over time
due to exposure to sunlight and pool chemicals. This cover must be replaced within
seven (7) years from installation (or earlier if the cover becomes damaged in any way).
BEFORE WORKING ON FILTER!
(1) Stop pump.
(2) Open air release valve.
(3) Release all pressure from system.
PUMPS REQUIRE HIGH VOLTAGE WHICH CAN SHOCK,
BURN, OR CAUSE DEATH.
BEFORE WORKING ON PUMP!
Always disconnect power to the pool pump at the
circuit breaker from the pump before servicing the
pump. Failure to do so could result in death or
serious injury to service person, pool users or
others due to electric shock.
RISK OF ELECTRICAL SHOCK OR ELECTROCUTION:

Pump and DE Element Filter System Installation and User’s Guide

Pump and DE Element Filter System Installation and User’s Guide
Section 1
Pump and DE Element Filter Overview
This system operates under pressure and if assembled improperly or operated
with air in the water circulation system it can separate and result in an accident
causing serious bodily injury. A warning label has been affixed to the filter and
should not be removed. Keep safety labels in good condition and replace if
missing or illegible. (For free labels call, (919)-774-4151). Pumps and filters
should never be tested or subjected to air or gas under pressure. All gases are
compressible and under pressure create a danger. Serious bodily injury or
property damage could occur if the pump or filter is subjected to air or gas
pressure.
1
The system consists primarily of a centrifugal pump, a DE element filter, a
connecting hose and a mounting base. Your centrifugal pump is driven by an
electric motor. The motor is directly attached to the pump impeller. As the
electric motor turns it causes the water to flow. The water flows into the hair
and lint pot inlet and through the basket assembly to pre-strain large particles.
The flow then enters the center of the pump housing. The flow goes through
the impeller into the stationary diffuser, out the pump discharge port, through
the connecting hose and into the filter inlet port at the bottom of the filter. The
water is distributed evenly across the DE filter element. The dirt is removed
by the element and the clean water flows through the outlet port at the bottom
of the tank. The clean water then returns to the pool through the piping or
hoses.
After a period of time, dirt will accumulate in the filter element causing a
resistance to the flow of water through the filter. This resistance results in a
diminished flow of water and a rise in the pressure of the filter. Eventually the
filter element will have removed so much dirt and the filter pressure risen to such
a point that it will be necessary to clean your filter.
The function of the filter is to remove suspended matter from the water. It does
not sanitize the water. For sparkling clear water, the water must be sanitized as
well as chemically balanced. Pool chemistry is a specialized area, please consult
your local pool specialist for specific details. In general, proper pool sanitation
requires a free chlorine level of 2 to 4 ppm and a pH range of 7.2 to 7.8. Your
filtration system should be designed to meet your local health codes. As a
minimum, you must be sure that your system will turn over the total volume of
water in your pool at least twice in a 24 hour period.

Pump and DE Element Filter System Installation and User’s Guide
Failure to operate your filter system or inadequate
filtration can cause poor water clarity obstructing visibility
in your pool and can allow diving into or on top of obscured objects, which
can cause serious personal injury or drowning.
This filter operates under high pressure. When any part of the circulating
system (e.g., clamp, pump, filter, valves, etc.) is serviced, air can enter the
system and become pressurized. Pressurized air can cause the lid or lock
ring to separate which may result in serious injury, death, or property
damage. To avoid this potential hazard, follow these instructions.
1. Before the assembly, disassembly, or adjustment of the lid or lock ring or
any other service of the circulating system:
(a) Turn the pump off and shut off any automatic controls to ensure the system
is not inadvertently started during the servicing;
(b) Open manual air relief valve;
(c) Wait until all pressure is relieved, pressure gauge must read zero (0).
2. Whenever installing the filter lock ring, follow the filter lid and lock ring
installation instructions exactly.
3. Once service on the circulating system is complete, follow system restart
instructions exactly.
4. Maintain circulation system properly. Replace worn or damaged parts
immediately (e.g., lock ring, pressure gauge, relief valve, o-rings, etc.).
5. Be sure that the filter is properly mounted and positioned according to
instructions provided.
1. Read and understand all instructions before attempting to install,
operate or maintain your pump and DE filter system.
2. Provide space and lighting for routine maintenance access. Locate the
system close to the pool. Install electrical controls (e.g., on/off switches,
timers, control systems, etc.) at least five (5) feet from the filter. This will
allow you enough room to stand clear of the filter during system start up.
Systems that are unassembled should be assembled at this point. See
special instructions A through P.
A. Make sure all electrical breakers and switches to the pump are switched
off, and disconnect the communication cable from the pump before
installing the base.
B. Remove all individual components from carton and inspect for any visible
damage. If carton or parts are damaged contact seller or freight
company.
C. Place the system support base on the ground close to the final location of
the unit. See Figure 1.

tape on the threads and tighten no more than one (1) turn past hand tight.
Connect the flex hose to this adaptor with a hose clamp and tighten with a
screwdriver.
6. Install the High Flow™ manual air relief valve to the lid of the filter. The
High Flow manual air relief uses the O-ring only, there is no need for
thread sealing compound. Position the system to safely direct water
drainage. Rotate the High Flow™manual air relief valve to safely direct
purged air or water. Water discharged from an improperly position filter or
valve can create an electrical hazard as well as damage property.
7. Install the pressure gauge in the ¼” NPT threaded hole in the tank lid,
using SOXPEHUVtape on the threads.
8. Now, move the system to its final position. The system must be placed on
level solid earth. The entire system filled with water can weigh over one
hundred pounds. Position the system so that the instructions, warnings and
pressure gauge are visible to the operator. Also, position the system so
that the piping connections and drain port are convenient and accessible for
servicing and winterizing.
9. Provide sufficient clearance around the filter to permit visual verification
that the lock ring is properly installed. See Figure 10.

Pump and DE Element Filter System Installation and User’s Guide
High Pressure:
Improper tank lid and lock
ring assembly could cause
the lid to separate and cause
serious injury and/or major
property damage.
If doubt exists as to the pressure to which the system will be subjected,
install an ASME approved automatic Pressure Relief or Pressure
Regulator in the circulation system for the lowest working pressure of any
of the components in the system.
14. Use sealant on all tapered male connections of pipes and fittings. Use only
sealant compounds suited for plastic pipe. Support pipe to prevent strains
on filter, pump or valve. DO NOT USE PETROLEUM BASED
PRODUCTS
15. Never store pool chemicals within ten (10) feet of your pool filter or pump.
Pool chemicals should always be stored in a cool, dry, well ventilated area.
Chemical fumes and/or spills can cause serious
corrosion to the filter and pump structural components. Structurally
weakened components can cause filter, pump or valve attachments to
separate and could cause serious bodily injury or property damage.
The system’s centrifugal pump operates with electrical
voltage, and can generate both vacuum and pressure in the water
system. When properly wired and plumbed, this pump will operate in a
safe manner.
High voltage can cause serious or fatal injury. Always
install a suitable GFCI at the power source of this unit as an added
safety precaution. Article 681-31 of the NEC requires that a GFCI be
used if this pump is used with a storable pool.
16. Avoid over tightening the pipe threads when connecting fittings to pump or
filter. Proper procedure is to apply a pipe sealant to the thread and then
install hand tight plus one (1) turn. DO NOT OVER TIGHTEN.
When performing hydrostatic pressure tests or when testing for external
leaks of the completed filter and plumbing system, insure that the
Maximum Pressure that the filtration system will be subjected to DOES
NOT EXCEED THE MAXIMUM WORKING PRESSURE OF ANY OF
THE COMPONENTS CONTAINED WITHIN THE SYSTEM. In most
cases, the maximum pressure will be stated on each component of the
system.
