OPERATOR’S MANUAL
SJDDG-3011 • 8.914-324.0 • REV. 7/12
For remote hookup, pull the hose from the hose reel to
the drain site. Attach the hose to the inlet of the pedal.
The pedal is designed for 3/8" hose fittings. If using a
1/4" hose, use adapter #8.705-129.0 as well. Then at -
tach the smaller hose (1/8" or 1/4") to the outlet side of
the pedal. Use the smaller hose to clear the drain line.
Ice Blockages
High pressure water can be used to clear an ice block-
age. A 3000 psi
(207 bar) gas jet can clear a 4" (102mm)
line at an approximate rate of one foot per minute. The
smaller electric jet will take twice as long. Ambient air
temperature will effect these times. Use a nozzle with a
forward jet. DO NOT allow the incoming water supply to
exceed 140°F
(60°C) or it could cause damage to the
pump. Remember to follow the cold weather precautions
found in the freeze protection section.
Spray Wand (Optional)
Follow the same procedures listed previously for safety,
set-up, operation and maintenance. To operate the spray
wand, connect the high pressure hose and trigger to the
machine. Turn on the water supply, then squeeze the trig-
ger to purge air from the system. Continue to squeeze
trigger as you start the machine.
Use caution when pressure washing. Wear goggles and
rubber gloves and boots. Analyze angle of spray and
anticipate angle of back splash. Do not point spray at
anyone including yourself. Do not put your hand in front
of water spray. It can penetrate the skin and cause a
need for amputation. It is best to start at a 45° angle at
a 7 to 10 ft.
(2 to 3m) distance from object to be cleaned.
Direct spray at close range can be powerful enough to
cause damage.
NOTE: Typical industry standard stipulates you hold the
high pressure spray nozzle approximately 6-8" from the
surface to be cleaned. When cleaning with a detergent,
apply from bottom up with an even left to right movement.
Rinse from top down with a similar motion. This will help
reduce potential streaking. Always apply soap to a dry
surface. This will enhance penetration and detergent
cling and reduce dilution of detergent with an already
wet surface.
If you have the dual-lance wand (optional) you may draw
detergents through the spray wand in conjunction with
the detergent injector mounted on the machine. First set
up the detergent injector system (see Detergent Injector).
Then simply turn the knob on the wand counterclockwise
so that water is flowing through the wide spray nozzle.
To spray water only, turn the knob to the clockwise po-
sition so that the water flows through the narrow spray
nozzle.
The spray wand option with the other jets may also be
used to spray detergent. To do so, simply turn the nozzle
on the end of the wand counterclockwise. As the spray
widens, more of the detergent will be drawn through the
wand. Turn the nozzle clockwise to reduce the detergent
flow and narrow the water spray pattern and return to
high pressure.
Detergent Injector (Optional)
The detergent injector is an option with the SJDDG-3011
and can be attached to the free end of the ball valve.
Do not attach detergent injector to the inlet side of the
pump. Detergents can damage pump.
To use the detergent injector, attach one end of siphon
hose to the injector and put the filter end in the detergent
solution. Be sure the end of the hose is at the bottom of
the container or bucket. Some models have adjustable
valves to control the amount of detergent drawn through
the hose.
Remember: Do not use corrosive material. See warn-
ing previously listed.
Regulating Pressure Unloader
The machine is equipped with a regulating pressure
unloader to prevent pressure overload in the event that
the nozzle is plugged or the ball valve or trigger is shut
off. When the machine is in the by-pass mode, the pump
will continue to run. However running in by-pass mode
for extended periods will cause damage to the pump;
no more than 5 minutes with the SJDDG-3011 pump.
Excessive temperatures will damage the pump and void
the warranty.
The machine also comes with thermal overload protec-
tion. When water temperature in pump increases to 140°F
(60°C) , the thermal relief valve will release hot water and
allow cool water to enter pump from fresh water supply.
To adjust unloader, loosen lock nut and turn the knob
clockwise to increase pressure and counterclockwise
to decrease pressure.
Caution: Do not overtighten
unloader. Tighten lock nut after adjustments are made.
