OPERATOR’S MANUAL
(15m) in length. If run without an adequate water supply, the pump will cavitate. Cavitation causes the pump
to vibrate, causing damage to the pump. Note: Lack of
water supply can lead to seal damage, causing a loss of
pressure and will void the warranty to the pump.
Maximum temperature from water source should not
exceed 140°F (60°C). Using water hotter than 140°F
(60°C) can cause damage to pump and void the warranty. If jet is being used to clear ice blockages, see
instructions on page 8.
Remove oil plug on top of pump and replace with dipstick
supplied.
Hose Selection Guide
Select the proper hose diameter for the line to be
cleaned. When using new hose, run water through it to
clean it out before attaching the nozzle.
PRE-OPERATION CHECK
Pump oil (SAE 30W non-detergent oil)
Cold clean fres h water suppl y (6 gpm • 5/8"
(15.875 mm) • 20 psi)
Hose, nozzle
Water filter (intact, non-restrictive)
SET-UP PROCEDURES
These machines are meant to be used at or near the
working area and under operator supervision. If machine
must be located out of sight of the operator, special controls may be required for proper machine operation and
operator safety.
Locate equipment on a solid level area with slopes for
drainage. Avoid areas where water can be sprayed at
machine. Before using the jet, make sure there are no
impurities in the incoming water supply. Turn the water
source on for at least 15 seconds, to remove any possible debris in the water before connecting hose to water
inlet swivel.
The inlet screen located inside the filter should be
cleaned before each use. To clean the inlet screen,
unscrew cap beneath the filter, remove the screen and
rinse thoroughly with water. Then replace screen.
Connect one end of a garden hose (not included) to
the water faucet — water supply not to exceed 100 psi
(6.9 Bar) and the other end to the water inlet of the jet
machine. (See component identification drawings on next
pages.) Use heavy duty 3/4" hose of no more than 50 ft.
When selecting hose size, consider that pressure is lost
as the water travels down the length of the hose. As the
length increases, the pressure decreases. In addition,
the smaller the diameter of the hose, the greater the
loss of pressure per foot will be. As an example, at 2
GPM (.13L/sec) a 1/4" (6.350 mm) hose will lose 180
lbs. (12.4 bar) of pressure over 100 ft. (30.5m) of hose,
yet a 3/8" (9.925mm) hose will only lose 25 lbs. (1.7 bar)
of pressure over the same length and at the same flow
rate. At 4 GPM, a 3/8" hose will lose 90 lbs. (6.2 bar) of
pressure over a 100 ft. (30.5m) length. The gauge reflects
pressure from the pump only, not pressure at the end
of the hose. It is important to select the largest possible
hose size in order to have as much pressure as possible
at the end of the hose.
Hoses of the same diameter may be coupled together
using the CC-1 coupling, but it is not recommended for
use in lines smaller than 8" (203mm) in diameter. The
long length of the hose connectors and coupling together
can get caught in bends in the line.
Coupling two different size hoses can be done through
the spray wand trigger or foot pedal.
It is not advisable to have two different hose sizes coupled
in a drain line. There is a tremendous loss of pressure
when combined, aside from the difficulty of getting around
bends.
The 3/8" (9.925 mm) and 1/4" (6.350 mm) hoses may
be attached to the fitting in the core of the hose reel
* Rotary Nozzles can be adapted to 1/8" and 3/8" hose using AD-3 or AD-4 adapters
using the swivel at one end of the hose. The 3/8" hose
may also be attached directly to the accessory outlet
by using a twist connect. The 1/4" and 1/8" (3.175mm)
hoses may be connected directly to the accessory outlet if an adapter fitting (AD-1 or AD-2) is used between
the hose and quick connect. Adapters may be ordered
separately.
Often, the 1/8" hose is used in conjunction with the spray
wand trigger to give the operator finger tip control. Remove the spray wand from the trigger and attach the
1/8" hose using the AD-3 adapter.
A foot pedal FP-1 valve is available that can be used as
a safety shut-off valve for all hose sizes. See foot pedal
section for installation and operating instructions.

Nozzles
A number of types of nozzles are available for drain
cleaning. Each has a different spray pattern. Some
nozzles may have a hole in the front to cut though the
stoppage. All will have holes in the back to drive the hose
down the line and clean the walls of the pipe. A tight spray
pattern (15°) has more driving power for long runs, a wide
spray pattern (40°) does a better job of cutting the grease
off the walls of the pipe. A combination of nozzles may
be required to clear a line. Always turn off the machine
and shut off valve before changing nozzles.
Make sure the nozzle you are using matches the pump
size. A 3000 psi (207 bar) pump requires a different
nozzle orifice than a 1500 psi (104 bar) pump. Mismatch-
ing nozzles with pump size will either cause too little
pressure which may not clear the drain, or too much
pressure which may damage the machine.
Check nozzles before and after each use for clogged
holes which can cause pressure to increase to dangerously high levels and damage the pump. A clogged hole
can be cleared by simply using the NCT Nozzle Cleaning
Tool.
Use the nozzle selection guide to determine what nozzle
you will need for various applications. Example: If a
nozzle is stamped #22, it is a JN-22, 15° rearjets, 2 GPM
(.13L/Sec) @ 1500 PSI (104 Bar) with a forward cutting
Optional:
Rotary nozzle scours
walls of pipe crystal clear
jet. Spring leader nozzles and down head nozzles are
special nozzles to help aid hose travel through the pipe
when there are alot of curves and bends.
Rotary Nozzles
Rotary nozzles are useful as a finishing tool. After the
line has been cleared, you may switch to the rotary
nozzle to more thoroughly clean the walls of the pipe.
Use these nozzles only in a predominantly straight run
since they are longer than regular nozzles and may get
caught in tight bends.

GENERAL'S JET SET
OPERATOR’S MANUAL
Check the labels of any substance you will spray. If
the label recommends any antidote or treatment,
___ be ready to use it.
___ Check that all lines and hoses are clear.
Check that the machine is connected to an adequate
___ water supply and that the water supply is on.
Check that traffic has not made the hose weak,
worn or damaged. Check the hose for pinching or
___ kinking. Replace any damaged hose.
___ Tighten all fluid connections securely.
OPERATING INSTRUCTIONS
Check all hoses for wear and damage. Tighten all
connections securely.
Check oil level of pump.
To begin, turn the water faucet on fully and purge air
from system.
Insert end of the jet hose 2 to 3 feet into the drain
line. Then open Jetter control valve.
Warning: Never point the end of the jet hose at a
person while operating.
Start-Up
1. Make sure that the Jetter control valve is turned on
and water is flowing through the nozzle.
2. Plug in GFCI power cord to proper receptacle and
voltage. CAUTION: Do not use additional extension
cord with machine to avoid electrical shock to the
operator.
3. Hold Jetter hose firmly to prevent it from whipping
around.
4. Turn motor switch on.
Vibra-Pulse
Pulsation makes the hose vibrate, helping the jet go
longer distances and around tight bends easier.
The pulse control valve is located on the front of the
pump. Simply turn the valve on to engage the pulse.
The pulse causes a pressure drop when it's engaged.
The pulse is most effective in a 1/8" hose. You'll note
less vibration with a 1/4" hose and almost none with a
3/8" hose. However the pulse is still effective, causing
the water to burst from the nozzle hundreds of times
per second.
If you are still having difficulty getting a hose around a
tight bend, switch to a smaller diameter hose.
Turn the pulse off before turning machine off.
Shut Down Instructions
After drain cleaning or spray washing is completed, run
clear water through the system. Always leave Jetter con-
trol valve in open position when turning off motor. Turn
off water supply and drain as much water from pump as
possible. Remove water supply hose from inlet. If you
are in a cold climate, see Freeze Protection.
Handy-Reel (Optional) HR-200
Position the reel at the drain site. Connect the jet machine to the inlet on the reel. Select and attach a nozzle
to the hose on the reel. Put the hose 2 to 3 feet into the
drain. Open the ball valve on the reel. Follow the start
up procedures.
Foot Pedal (Optional) FP-1
The foot pedal is used with any jet manufactured by
General (see page 5 or 6). It interrupts the flow of water
between the pump and the nozzle while leaving both
hands free to guide the hose. The pump will continue to
run in by-pass mode. Do not leave pump in by-pass for
more than a few minutes or the pump can be damaged.
(See Regulating Pressure Unloader on Page 9).
The foot pedal may be hooked up either at the machine
or remotely at the drain site. To use the foot pedal at the
machine, remove the hose going to the swivel on the
hose reel and attach it to the inlet side of the foot pedal.
Then, connect the accessory hose (6AHW) between the
outlet of the pedal and the swivel on the hose reel. Some
jet models may need the added length of the accessory
hose on the inlet side of the pedal.
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 the AD-1 as well. Then attach the smaller
hose (1/8" or 1/4") to the outlet side of the pedal. Use
the smaller hose to clear the drain line.
Spray Wand (Optional) SWA-1500
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 trigger 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. 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. 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.
Detergent Injector (Optional) CMA-1
Refer to Component Indentification for placement of
injector. The detergent injector is an option with the J1400 and J-1600.
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 counterclockwise.
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 Jetter control valve or trigger 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 J-1400
and J-1600 pump. Excessive temperatures will damage
the pump and void the warranty.
The machine also comes with thermal overload protection. 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.
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 container. 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 compressed 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.
Ice Blockages
High pressure water can be used to clear an ice blockage.
A 3000 psi (207 bar) gas Jetter 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 15° 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 temperatures.
Check PRESSURE HOSE for wear and damage. Damaged 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.
