OPERATION
SET-UP
1. Locate the jet near the drain line on a level surface with drainage.
Tip: Ideally, the drain line should be cleared from the downstream
side, that is, from the street back toward the house. If you must
clear the line from the drain toward the street, you may need to
use a siphon pump to clear away excess water.
2. Check the oil level in the pump. If low, fill with SAE 30 weight non-
detergent oil.
3. Check the inlet filter to make sure it’s clean before each use. To
clean, unscrew filter cap, remove the screen and rinse thoroughly
with water. Then, replace screen.
4. Check that incoming water supply is clean and free of debris.
Turn the water source on for at least 15 seconds to remove any
possible debris in the water before connecting hose to water inlet.
5. Connect one end of a water supply hose (not included) to the wa-
ter supply and the other end to the water inlet of the jet machine.-
Water supply must be a minimum of 20 psi and not to exceed 100
psi. Caution: Water temperature must not exceed 140 degrees or
damage to the pump can occur. Use only heavy duty 3/4” hose of
2. Make sure the nozzle you are using matches the pump size. A
3000 psi pump requires a different nozzle orifice than a 1500 psi
pump. Mismatching nozzles with pump size will either cause too
little pressure, which may not clear the drain, or too much pres-
sure, which may damage the machine.
3. 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.
4. Use the nozzle selection guide to determine what nozzle you will
need for various applications. Examples: If a nozzle is stamped
#12, it is a JN-12, drilled for 1.7 GPM @ 1500 PSI with several
15° rear jets and one forward cutting jet.

JET ASSEMBLY
x
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.
x
Jet must be stored and operated in horizontal position. Never
store in upright position or oil may leak from pump. If low, fill with
SAE 30 weight non-detergent oil.
x
Jet 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 operator, special controls may be required for proper ma-
chine operation and operator safety
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 pre-
dominantly straight run since they are
longer than regular nozzles and may
get caught in tight bends.
Wide spray flushing nozzle cleans
inside of pipe thoroughly.
Powerful penetrating nozzle cuts
through grease and ice.
SPECIALTY NOZZLES
Spring leader nozzles and down head
nozzles are special nozzles to help
hose travel through the pipe when
there are a lot of Tee’s, curves, and
bends.
