2.0 SAFETY

CAUTIONAny alterations to the product or its markings could diminish safety and constitutes a misuse of this product.

CAUTIONStrainers must be properly connected. Mismatched or damaged connectors may cause leaking or uncoupling under pressure, which may result in injury.

3.0 GENERAL INFORMATION3.1 LOW LEVEL STRAINERHigh volume low-level strainer is made of hard anodized and powder coated aluminum. Clog-resistant stainless steel fi lter has over twice as much fl ow area as a 6” hose. This keeps friction loss down to 0.5 psi (1” Hg) at 1500 gpm and reduces the potential for air vortexes to form as water sinks towards the 2.5” minimum usable depth. If desired, the low-level strainer can be held just under the surface of the water through the addition of the low density polyethylene (LDPE) fl oat. Oversized sealed ball pivot allows 45° range of hose angle without constricting the fl ow path. Optional Jet Siphon substantially increases suction lift capability. The Jet Siphon is also useful for tank shuttle operations, pump priming, and dewatering without the need for a trash pump.

3.2 BARREL STRAINERThe jumbo barrel strainer is made of durable molded nylon. The size and shape minimize pressure loss and promote a continuous draft by preventing air vortexes. The jumbo barrel strainer can be held just under the surface of the water through the addition of the low density polyethylene (LDPE) fl oat.

1.0 MEANING OF SAFETY SIGNAL WORDSA safety related message is identifi ed by a safety alert symbol and a signal word to indicate the level of risk involved with a particular hazard. Per ANSI standard Z535.6-2006, the defi nitions of the four signal words are as follows:

DANGERDANGER indicates a hazardous situation which, if not avoided, will result in death or serious injury.

WARNINGWARNING indicates a hazardous situation which, if not avoided, could result in death or serious injury.

CAUTIONCAUTION indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury.

NOTICENOTICE is used to address practices not related to personal injury.


3.3 USE WITH SALT WATERUse with salt water is permissible provided the equipment is thoroughly cleaned with fresh water after each use. The service life of the equipment may be shortened due to the eff ects of corrosion, and is not covered under warranty.

4.0 MAINTENANCEThe TFT strainer should be disconnected, cleaned, and visually inspected at least twice annually, or as water quality and use may require. Moving parts such as the pivoting outlet and couplings should be checked for smooth and free operation.As needed, the spherical pivot surface of the strainer body should be cleaned and coated lightly with a silicone-based grease such as Dow Corning 112. Wipe off excess grease as only a thin fi lm of grease is needed to overcome friction.Any scrapes that expose bare aluminum should be cleaned and touched up with enamel paint such as Rust-Oleum. Replace any missing or damaged parts before returning to service.Prior to reassembly, fastener threads should be cleaned and coated with a stripe of Loctite 242 (blue) removable thread locker to prevent loosening over time.

6.0 USE OF THE LOW LEVEL STRAINER6.1 USE WITHOUT JET SIPHON

1. Complete hose connections using hard suction hose2. Immerse the strainer in at least 6” of water3. Tie the strainer off to a robust object4. Engage the pump primer to completely fi ll the suction hose5. Adjust the strainer base to sit fl at 6. Commence pumping

6.2 USE WITH JET SIPHON

WARNINGDo not use LDH lay-fl at hose directly between the strainer outlet and fi re pump inlet as the sole water supply to a fi re. Lay-fl at hoses can be sucked fl at or kinked, which will interrupt the water supply and could result in serious injury or death to persons dependent on water fl ow.

• Always use hard suction hose between the strainer outlet and fi re pump inlet.• Use of lay-fl at hose with the strainer is appropriate only when using the jet siphon for transfer

to a non-pressurized tank, or for dewatering.The jet siphon can increase the water transfer up to 400% using the Venturi eff ect.Maximum jet siphon inlet pressure is 200 PSI (13.8 bar).

CAUTIONChanging fl ows or charging the jet siphon can cause the strainer to shift as hoses stretch, straighten, and become pressurized. Injury can result from shifting hoses or loss of water supply from tank damage. Tie off the strainer to a robust object before initiating fl ow. Charge the hose slowly and avoid abrupt changes in fi re fl ow.

Jet siphon coupling size: 1.5”Jet siphon nozzle diameter: 1”

1. Connect a fi re hose to the jet siphon2. Allow enough slack in the fi re hose to approach the inlet without kinks3. Complete the strainer discharge connections4. Immerse the strainer in at least 6” of water5. Tie the strainer off to a robust object6. Pressurize the jet siphon7. Adjust the strainer base to sit fl at8. Commence pumping


7.0 USE WITH FLOATThe optional fl otation device allows the strainer to collect clean water from ponds, lakes, and rivers. With the fl oat installed, the strainer inlet hangs below the water level to avoid sucking surface air and bottom debris. The fl oat is capable of supporting up to 30 ft of hose to extend well beyond safety ledges of residential ponds. The fl oat nests compactly over the strainer for storage. Disabling the swinging action of the fl oat pivot will change the buoyancy, resulting in loss of prime.

7.1 FLOAT REMOVALIt is not necessary to remove the fl oat when using the strainer for low level use. However, a tethered latching pin allows the fl oat to be removed or installed instantly if desired. To remove the fl oat, unlatch the pin and slide it out.
