I. Product Safety

Important:

Before installing and operating this equipment, read & study this manual
thoroughly. In addition, the following points should be adhered to ensure
the safety of equipment and personnel:

1. All personnel who may be expected to use this equipment
must be thoroughly trained in its safe and proper use.

2. Before flowing water from this device, check that all
personnel (fire service and civilian) are out of the stream
path. Also, check to make sure stream direction will not
cause avoidable property damage.

3. Become thoroughly familiar with the hydraulic characteristics
of this equipment and the pumping system used to supply it.
To produce effective fire streams, operating personnel must
be properly trained.

4. Whenever possible, this equipment should be operated from
a remote location. Do not needlessly expose personnel to
dangerous fire conditions.

5. Never attempt to view or change the SM-1000-HF, SM­1000E-HF, SM-2000-HF, or SM-2000E-HF foam nozzle
proportioning rate settings while the nozzle is in operation.

6. The nozzle must be properly mated and tightened. Failure
to do so could result in leaks or may cause injury or death.

7. After each use and on a scheduled basis, inspect equipment
per Maintenance on page 5 instructions.

NOTE: The 55 gallon drum of foam concentrate should be positioned as
close to the monitor as possible without interfering with the desired travel
of the monitor.

1. Attach the nozzle to the monitor discharge. Hand tighten with the foam
inlet nipple down.

2. Remove the small bung hole plug from the 55 gallon drum & install the
vacuum breather. Use Teflon tape or pipe thread sealant to seal the
threads.

3. Remove the large bung hole plug and install the pickup tube. Use Teflon
tape to seal the threads. Tighten so that the 2.0 threaded connection at
the top is pointed at the nozzle.

4. Make sure the rubber gaskets are in place before connecting one end of
the pickup hose to the nipple on the nozzle, and the other to the male
thread on the pickup tube. Tighten both connections.

5. Tighten the nozzle onto the monitors discharge using a spanner wrench.

The proportioning rate on the SM-1000-HF and SM-1000E-HF can
only be adjusted or viewed when the water supply valve is close.

1. Firmly grasp the flood plate/baffle head assembly.

2. Rotate until the desired proportioning rate arrow is pointing at
the foam inlet port. See Figure .

3. Listen for audible click noise indicating that the nozzle is in the
detented position.

Note: It may be necessary to use a strap wrench in order to rotate
the assembly into place. Use care to avoid damage to the nozzle.

2. Pattern Control

Manual

1. Grasp the handle firmly.

2. Rotate clockwise for straight stream. Rotate counter-clockwise
for full fog. The full stroke of the pattern requires 180° of input
rotation.

Motor

Male Contact

Female Contact

The SM-1000E-HF and SM-2000E-HF nozzle uses a 11-15 VDC/1-2
Amp motor to adjust pattern control. Positive power to the male
contact with respect to the female contact will generate a fog pattern.
Positive power to the female contact will generate a straight stream.

IV. Maintenance

A) Cleaning

The nozzle should be flushed thoroughly after each use. This is
accomplished by flowing the nozzle with a clean water source for both
water and foam inlets. Ensure the nozzle is set to the largest
proportioning rate.

B) Pilot Assembly

Caution:

Do not allow the piston head and baffle head to turn. If necessary, use a
strap wrench to secure it while moving the pilot valve assembly.

Figure 5 - Pilot Valve Assembly

1. Using a 5/
plate.

2. With the aid of a pair of channel lock pliers, remove the pilot valve
assembly by turning it counter clockwise.

3. Using an air nozzle and pressurized air source, blow through the holes
in the spring adjustment nut to remove any small debris.

” Allen wrench, remove the four screws that retain the flood

4. Submerge the pilot valve assembly in warm soapy water. While
submerged, depress and release the spring-loaded pilot several times.

Do this by inserting a ¼” wood dowel (or plastic end of a pen) into the

open end of the pilot guide stem.

5. Remove the assembly from the soapy water. Using an air nozzle and
a pressurized air source, blow air through the holes in the spring
adjustment nut to remove any debris.

6. Apply a light coating of grease to the pilot valve assembly threads and
stem.

7. Re-insert the pilot valve assembly making sure that the o-ring in the
back of the baffle head is aligned with the pilot valve port in the piston
head. Screw the pilot valve assembly in clockwise by hand until it is
firmly tight.

8. Apply a drop of Loc-Tite removable thread locker to each retaining
screw. Insert the screws through the holes in the flood plate and into
the baffle-head. Tighten the screws firmly using the 5/32” Allen wrench.

C) Storage

After use, the nozzle should always be stored so that the tip is pointed
downward. This will allow the water to drain from the nozzle.

D) General

 On a monthly basis, operate the pattern control through a full range of

motion from full fog to straight stream.

 If required, apply a light coating of lithium grease to the nozzle body in

the area where it contacts the pattern control sleeve.

 Inspect and clean the pilot assembly as outlined in Section IV

Maintenance B) Pilot Assembly. Do this quarterly or as dictated by

water conditions and frequency of use.

 Periodically check that fittings are leak free and replace gaskets as

required.
