Warning: Read instruction manual before use. Operation of this device without understanding the manual and receiving proper training is a misuse of this equipment. Users who have not read and understood all operating and safety instructions are not qualified to operate this eductor. This manual should be kept available to all operating and maintenance personnel. This instruction manual is intended to familiarize firefighters and maintenance personnel with the operation, servicing, and safety procedures associated with the eductor.

2.0 Safety

• Quick-acting pattern control from straight stream to wide fog

• Fixed fog teeth

• Stainless steel spinning fog teeth available on some models

• Easily flushable while flowing to clear trapped debris

• Stainless steel shutoff ball

• Quick-change rear valve seat

Danger: An inadequate supply of nozzle pressure and/or flow will cause an ineffective stream and can result in injury, death or loss of property. See flow chart on pages 6 & 7 or call 800- 348-2686 for assistance.

Warning: This equipment is intended for use by trained personnel for firefighting. Their use for other purposes may involve hazards not addressed by this manual. Seek appropriate guidance and training to reduce risk of injury.

Warning: Nozzle reaction will vary as supply conditions change: such as opening or closing other nozzles, hose line kinks, changes in pump settings, etc. Changes in spray pattern or flushing will also affect nozzle reaction. The nozzle operator must always be prepared in the event of those changes. Failure to restrain nozzle reaction can cause firefighter injury from loss of footing and/or stream protection.

Warning: If nozzle gets out of control or away from operator, retreat from nozzle immediately. Do not attempt to regain control of nozzle while flowing water. Injury from whipping can occur.

Warning: Water is a conductor of electricity. Application of water solutions on high voltage equipment can cause injury or death by electrocution. The amount of current that may be carried back to the nozzle will depend on the following factors:

• Voltage of the line or equipment

• Distance from the nozzle to the line or equipment

• Size of the stream

• Whether the stream is solid or broken

• Purity of the water

Caution: Fire streams are capable of injury and damage. Do not direct water stream to cause injury or damage to persons or property.

2.1 Various Models and Terms
Selectable Flow: A nozzle with a discharge orifice that can be set to a user selected position. In each position the nozzle acts as a fixed orifice nozzle.
Fixed Flow: A nozzle with a discharge orifice that is a fixed opening size. The user can set the opening to flush positions, or on tip only models to the OFF position.
Tip Only: A nozzle without an intergal ball shutoff valve.
Quadrafog, Thunderfog nozzles are available in a variety of flow ranges and configurations. All models deliver the selected flow when the rated pressure is supplied to the nozzle. Flow settings and recommended hose sizes are:

2.2 General Information
NH (National Hose Threads per NFPA #1963) threads are standard on all nozzles. Other threads such as NPSH (National Pipe Straight Hose threads per ANSI/ASME #B1.20.7) can be specified at time of order.

Caution: Nozzle must be properly connected. Mismatched or damaged threads may cause nozzle
to leak or uncouple under pressure and could cause injury.

Caution: Do not couple aluminum to brass. Dissimilar metals coupled together can cause galvanic
corrosion that can result in inability to unscrew threads or complete loss of thread engagement.

3.0 Flow Characteristics

4.0 Nozzle Controls

4.2.2 Flush Setting
Debris may become trapped in the nozzle causing poor stream quality, shortened reach and reduced flow. To remove trapped debris, the nozzle can be flushed as follows: While still flowing water, rotate the selector ring into the flush position. This will open up the nozzle, allowing debris to pass through. Rotate the selector ring out of flush to continue normal operations. The nozzle operator must be prepared for a change in nozzle reaction when returning the nozzle from the flush position to retain control of the nozzle.

Warning: Large amounts or pieces of debris may be unflushable and can reduce the flow of the nozzle resulting in an ineffective flow. In the event of a blockage, it may be necessary to retreat to a safe area, uncouple nozzle and remove debris.

4.2.3 Shutoff Setting (Tip Only Models)
On tip-only models the selector ring has a shutoff setting to stop the nozzle flow. To shut off the nozzle, rotate the selector ring clockwise (as seen from the operating position behind the nozzle) into the "OFF" position. Rotate counterclockwise into a flow setting to open nozzle.

4.3 Pattern Control
The Quadrafog, Thunderfog nozzles have full pattern control from straight stream to wide fog. Turning the SHAPER clockwise (as seen from the operating position behind the nozzle) moves the SHAPER to the straight stream position. Turning the SHAPER counterclockwise will result in an increasingly wider pattern. Since the stream trim point varies with the flow, the stream should be 'trimmed' after changing the flow to obtain the straightest and furthest reaching stream. The nozzle reaction is greatest when the shaper is in the straight-stream position. The nozzle operator must be prepared for a change in reaction as the pattern is changed.

5.0 Fireground Use

PDP = NP+FL+DL+EL

6.0 Field Inspection

Caution: Any alteration to the nozzle and its markings constitutes a misuse of this product and could diminish safety.

All nozzles are factory lubricated with high-quality silicone grease. This lubricant has excellent washout resistance and long-term performance. If your department has unusually hard or sandy water, the moving parts may be affected. Foam agents and water additives contain soaps and chemicals that may break down the factory lubrication.

The moving parts of the nozzle should be checked on a regular basis for smooth and free operation and signs of damage. IF THE NOZZLE IS OPERATING CORRECTLY, THEN NO ADDITIONAL LUBRICATION IS NEEDED. Any nozzle that is not operating correctly should be immediately removed from service and the problem corrected.

10.0 Inspection Checklist

1. There is no obvious damage such as missing, broken or loose parts, damaged labels, etc.

2. Coupling is tight and leak free

3. Valve handle moves freely though full range and shuts off flow

4. Nozzle flow is adequate as indicated by pump pressure and nozzle reaction
