3. The "SM/SMBW" Series Filter has been listed and approved by the National Sanitation foundation. This booklet will enable you to install and operate your pool filter in the correct manner. Correct installation and operation will result in the trouble free operation of a quality product, as well as prevent unnecessary repairs.

4. Model SMBW Filter System a. Standard SM Series Filter with built-in backwash

valve. Simplifies plumbing installations.

U.S. Patent No. 4,414,109 4,328,833

5. Model SM Filter System a. Standard SM Series requires separate valves for

backwash.

CAUTION

Before starting any filter system, be sure the pump has been adequately primed by filling the strainer on the pump with water. Failure to do so will result in pump seal problems. When installing in conjunction with a heater, a one-way check valve

should be used between the filter and heater to prevent the backflow of hot water from damaging the filter internals.

B. WHAT IS DIATOMACEOUS EARTH AND HOW DOES IT FILTER WATER?

1. Diatomaceous earth is the skeletal remains of microscopic one-cell aquatic plants called diatoms, also known as diatomite, D.E., and more properly diatomaceous earth.

2. Under the microscope, these minute diatoms show an amazingly intricate design and variety of forms, such as discshaped, boat-shaped, needle-like and many have a lace-like porous structure.

3. When used as a filter aid, the diatomaceous earth is mixed with water to form a slurry for filter 'precoat'. This mixture is introduced into the filter system by means of a slurry pot, or by pouring directly into the surface skimmer with the pump running. The minute diatoms are deposited on the outer surface of the filter elements, forming a 'strawpile' layer or cake by interlacing and overlapping, and thus providing countless microscopic channels which entrap suspended impurities, but allow clear water to pass through without clogging.

4. We recommend the use of D.E. which is sold and labeled for use with swimming pools and spas. These grades of D.E. typically have a median particle size of 34 microns, which is ideal for most applications.

WARNING

Failure to operate your filter system or inadequate filtration can cause poor water clarity obstruction visibility in your pool and can allow diving in shallow pool area, or diving into or on top of obscured objects which can cause serious bodily injury or drowning.

C. FILTER PRECOATING INSTRUCTION:

1. Mix the Diatomaceous Earth in a pail of water to form a slurry, then pour the mixture directly into the surface skimmer with the pump running. Insure that the right quantity of D.E. is used as shown in the table.

SECTION II. FILTER INSTALLATION.

A. GENERAL INFORMATION

THIS FILTER OPERATES UNDER HIGH PRESSURE. WHEN ANY PART OF THE CIRCULATING SYSTEM, e.g., CLAMP, PUMP, FILTER, VALVE(S), ETC. IS SERVICED, AIR CAN ENTER THE SYSTEM AND BECOME PRESSURIZED. PRESSURIZED AIR CAN CAUSE THE LID TO BE BLOWN OFF WHICH CAN RESULT IN SEVERE INJURY, DEATH, OR PROPERTY DAMAGE. TO AVOID THIS POTENTIAL HAZARD, FOLLOW THESE INSTRUCTIONS.

1. BEFORE REPOSITIONING VALVE(S) AND BEFORE BEGINNING THE ASSEMBLY, DISASSEMBLY, OR ADJUSTMENT OF THE CLAMP 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 THE AIR RELIEF VALVE; (C) WAIT UNTIL ALL PRESSURE IS RELIEVED.

2. WHENEVER INSTALLING THE FILTER CLAMP FOLLOW THE FILTER CLAMP 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., clamp, pressure gauge, valve(s), O-rings, etc.

5. BE SURE THAT THE FILTER IS PROPERLY MOUNTED AND POSITIONED ACCORDING TO INSTRUCTIONS PROVIDED.

WARNING

1. New pools have a tremendous amount of debris due to dirt in the lines, plaster dust, etc. This debris will be removed by the filter and will require daily backwashing of the filter until it is removed. Check the pressure gauge daily and backwash the filter when the pressure increases 8 - 10 psi over the initial reading. It will require several backwashings before the pool is clean. Thereafter, the normal filter cycle will be several weeks in a properly designed system. The filter cycle is lengthened or shortened by contamination loads.

2. When installing backwash lines, it is recommended to install a vacuum breaker where the backwash line is over 40 feet long, or if the line discharges 10 feet or more lower than the water level of the pool. Operating at excessive vacuum levels can cause the tank to implode, which voids the warranty.

3. A check valve is recommended between the filter and heater to prevent hot water backup from damaging the filter internals.

4. The maximum operating pressure of the tank is 50 psi. Never operate the unit above this pressure or attach a pump to this filter that has a shut off pressure higher than 50 psi.

5. Never install a chemical feeder or ozonator upstream of the filter. Always locate downstream with a check valve between the feeder and the filter.

6. A positive shut off valve is not recommended downstream of the filter and/or heater. If the system is ever run with such a valve closed, the internal air vent becomes inoperative and an explosive situation could exist. Running the system with no flow can seriously damage the equipment.

7. Clean your filter when pressure reads between 8-10 psi higher than the original starting pressure. Your filter pressure reading will increase as it removes dirt from your pool. However, this buildup of pressure will vary due to different bathing loads, temperature, weather conditions, etc.

a. MY ORIGINAL STARTING PRESSURE IS ___________ psi (pounds per square inch). I

SHOULD BACKWASH (CLEAN) THE FILTER AT __________ psi.

8. Check carton for any evidence of damage due to rough handling in shipment. If carton or any filter components are damaged, notify freight carrier immediately.

9. The filter should be mounted on a level concrete slab. Position the filter so that instructions, warnings and the pressure gauge are visible to the operator. It also should be positioned so that the piping connections, control valve and drain port are convenient and accessible for servicing and winterizing.

Rev. C 7-6-01 3 P/N 075122

10. Provide space and lighting for routine maintenance access. Do not mount electrical controls over filter. 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.

11. Allow sufficient clearance around the filter to permit visual verification that the clamp is properly installed around the tank flanges, see Figure 1.

12. Allow sufficient space above the filter to remove the filter lid for cleaning and servicing. This distance will vary with the model of filter you are using. See Table 1. for the required vertical clearance.

B. TO OPERATE FILTER

WARNING

1. Set rotary valve handle in the filter position.

2. Open air relief valve on top of filter. STAND CLEAR OF THE FILTER.

3. Start pump and wait until a steady jet of water emerges from air relief valve, then close valve.

4. Introduce the required amount of Diatomaceous Earth into filter, see page 2.

5. Filter will operate efficiently until pressure gauge indicates time for backwashing.

C. TO BACKWASH (CLEAN) FILTER

CAUTION

To prevent equipment damage and possible bodily injury and/or property damage, always turn the pump off before changing the valve positions.

1. Pressure backwashing is accomplished in three easy steps: a. Turn pump off.

b. Rotate handle of rotary valve 90

ST AND CLEAR OF THE FIL TER.

c . Turn pump on. d. Backwash for approximately two minutes or until effluent

appears clean. When backwashing is complete, turn pump off, rotate handle back to filter position and you are ready for filter operation again. Precoat filter with D.E. as shown on page 2.

as shown in Figure 2.
