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.
Detergent Injector (Optional)
Refer to Component Indentification for placement of
injector. The detergent injector is an option with the
SJHE-1500 and SJPE-1650.
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. Turn the nozzle on the end of the wand coun-
terclockwise.
REMEMBER: Do not use corrosive material. See
warning previously listed.
Adjusting Pressure Unloader Valve
The machine is equipped with an adjustable pressure
unloader to prevent pressure overload in the event that
the nozzle is plugged or the Jetters control valve or trig-
ger gun 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 SJHE-
1500 and SJPE-1650 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 pressure unloader turn the knob clockwise to
increase pressure and counterclockwise to decrease
pressure. Caution: Do not exceed operating pressure.
Ice Blockages
High pressure water can be used to clear an ice blockage.
A 3000 psi (207 bar)gasJettercancleara4"(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.
Freeze Protection
To protect your machine from severe damage caused
by water freezing inside the components, it is important
to winterize it whenever it is subjected to freezing tem-
peratures.
The best way to protect the system is to keep it out of
the cold. Barring that, the next best way is to flush the
system with anti-freeze. To do so, simply attach a short
garden hose (not to exceed four feet) to inlet on the
pump and put other end into the anti-freeze container.
Be sure to remove the nozzle from the hose. Turn the
machine on to draw anti-freeze into the system. When
anti-freeze flows out of the end of the hose, turn the
machine off. With optional spray wand and trigger gun
follow above procedure. Cycle trigger on/off so that the
anti-freeze will flow into unloader and detergent injector
section of machine.
When preparing to operate equipment the next time,
remove the anti-freeze. To do so, reconnect water source,
turn pump on and direct flow of anti-freeze back into con-
tainer. Be careful not to dilute anti-freeze with incoming
water supply. Anti-freeze, if kept relatively undiluted can
be used again and again.
Hoses can also be protected from freezing by using com-
pressed air to clear them of residual water. Remember
to remove nozzle from jet hose and hold trigger of spray
wand in open position.
MAINTENANCE
Regular inspection is the key to preventing breakdowns
and prolonging the life of the equipment. Follow this
simple procedure religiously.
DAILY
Check that the water supply is adequate.
Check that the nozzle on the spray wand is not clogged
or worn out.
Check that the PUMP OIL LEVEL is within operating
range on dipstick or sight glass.
Check the INLET FILTER.
Check GFCI function.
WEEKLY
Check PRESSURE HOSE for wear and damage. Dam-
aged hose can be repaired at a local service dealer or
by your equipment dealer.
Maintenance Schedule
Use the following maintenance schedule at the stated
intervals or when your routine turns up a problem.
Pump Crankcase Oil Change: Service after the 1st
month or after 50 Hours. Then service every year or 500
hours. Use SAE 30W Non-Detergent Pump Oil to full
mark on dipstick or to center of sight glass.
