JET HOSE
1.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 4 GPM, a 3/8” hose will lose 90 lbs. of pressure over a
100 ft. 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.
2.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” in diameter. The long length of the hose connectors and coupling together can get caught in bends in the line. 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.
4.Use the nozzle selection guide to determine what nozzle you will need for various applications. Examples: If a nozzle is stamped #52, it is a JN-52, drilled for 4 GPM @ 3000 PSI with several 15° rear jets and one forward cutting jet.
Powerful penetrating nozzle cuts through grease and ice.
Wide spray flushing nozzle cleans inside of pipe thoroughly.

JET NOZZLES
1.A variety of jet nozzles are available for drain cleaning. Each has a different spray pattern and purpose. Some nozzles may have an orifice in the front to cut through 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 of the walls of the pipe. A combination of nozzles may be required to clear a line. Always turn off the machine and turn off output valve before changing nozzles.
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 pressure, 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.
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.
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.
CHAIN SAW NOZZLES
Chain saw nozzles spin at up to 10,000 rpm to rip through roots. Lengths of chain can be quickly and easily switched for different diameter pipes.

6.Connect one end of a water supply hose (not included) to the water 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 no more than 50 ft. 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.
7.Maximum temperature from the water source should not exceed 140°F (60°C). Using water hotter than 140°F (60°C) can cause damage to the pump and void the warranty. If jet is being used to clear ice blockages, see instructions on Ice Blockages.
8.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.
JET 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.
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.
Gas jets are shipped with oil in the engine. Consult motor manufacturer’s manual for correct weight and amount.
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 machine operation and operator safety
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 nondetergent oil.
3.Check the oil level in the engine. If low, fill with oil weight recommended in the motor manufacturer’s manual.
4.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.
5.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.
OPERATION
NEVER POINT THE END OF THE JET HOSE AT A
PERSON WHILE OPERATING.
1.Select the correct jet hose size to match the line size you are clearing. (See Hose Section Guide) Check all hoses for wear and damage. Tighten all connections securely.
2.Select the correct nozzle and attach to the end of the hose. (See Nozzle Selection Guide) Note: If you are using a new jet hose, run water through it to flush out debris before connecting a nozzle.
3.Insert the jet hose 2 to 3 feet into the drain line before turning on machine.
4.Turn on the water supply valve fully to allow for maximum flow.
5.Turn on the jet output valve and allow water to run through the supply hose, jet, and jet hose to purge air from system before turning on the machine.
6.Make sure that the output valve is turned on and the water is flowing.
7.Start the engine using the Engine Start-up procedures listed below.
GAS ENGINE START-UP
1.Make sure that the ball valve is turned on and water is flowing.
