2. All installations must comply with local codes. Contact your electrician, plumber, utility company or the
selling distributor for specific details. To comply with
the National Electrical code (NFPA 70) and provide
additional protection from risk of electric shock, the
machines are equipped with a UL approved ground
fault circuit interrupter (GFCI) power cord.
RISK OF EXPLOSION:
DO NOT USE WITH
FLAMMABLE LIQUIDS.
CAUTION: To reduce the risk of injury, read operating instructions
carefully before using.
1. Read th e owner' s manua l
thoroughly. Failure to follow
instructions could cause malfunction of the unit and result
in death, serious bodily injury
and/or property damage.
WARNING: Flammable liquids
can create fumes which can ignite causing property damage or
severe injury.
WARNING: Risk of explosion -do not spray flammable liquids.
3. Risk of explosion - do not spray flammable liquids
or operate in an area where flammable or explosive
materials are used or stored.

Circuit Interuptor (GFCI). The
use of an additional extension
cord by the operator should not
be used as it will not provide protection to the op-
erator of electrical shock. The machine must be
electrically grounded. It is the responsibility of the
owner to connect this machine to a UL grounded
receptacle of proper voltage and amperage ratings.
Do not spray water on or near electrical components.
Do not touch machine with wet hands or while
standing in water. Always disconnect power before
servicing.
5. Grip cleaning wand or hose securely with both hands
before starting the cleaner. Failure to do this could
result in injury from a whipping wand or hose.

ASSEMBLY
Upon arrival, inspect the shipping crate for damages.
Uncrate and examine all parts. Note any damage to machine or components for claims against freight carrier.
Jets have antifreeze in the pump to protect it from freezing conditions during shipment and storage. If machine
will be stored and operated in a cold climate, follow
Freeze Protection instructions on page 9.

(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.
