Jet-Set JM-1000™
6
SPECIAL APPLICATIONS
ICE BLOCKAGES
High pressure water can be used to clear an ice blockage. A 3000 psi
gas jet can clear a 4” line at an approximate rate of one foot per min-
ute. The smaller, electric jet will take twice as long. Ambient air tem-
perature will effect these times. Use a 15° nozzle with a forward jet.
DO NOT allow the incoming water supply to exceed 90°F (32°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 freez-
ing inside the components, it is important to winterize it whenever it is
subjected to freezing temperatures.
The best way to protect the system is to keep it out of the cold. Bar-
ring 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 jet 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. When preparing to operate
equipment for the next job, remove the anti-freeze. To do so, recon-
nect water source, turn jet 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 the nozzle from
the jet hose.
SHUT DOWN INSTRUCTIONS
After drain cleaning or spray washing is completed, run clear water
through the system. Turn off water supply and drain as much water
from the pump as possible. Remove water supply hose from inlet. If
you are in a cold climate, see Freeze Protection section.
PULSE
Pulsation makes the hose vibrate, helping the jet go longer distances
and around tight bends easier. Pulse causes the water to burst from
the nozzle hundreds of times per second. Pulse is most effective in
the 1/8” hose.
1. Select the correct jet hose size to match the line size you are
clearing. (See Hose Guide) Check all hoses for wear and dam-
age. Tighten all connections securely. Note: If you are using a new
jet hose, run water through it to flush out debris before connecting
a nozzle.
2. Select the correct nozzle and attach to the end of the hose. (See
Nozzle Selection Guide) Clean nozzles before and after each use.
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 shut-off valve at the end of the supply hose.
6. Allow water to run through the supply hose, through the jet, and
out of the jet hose to purge air from system before turning on the
machine.
7. Plug in GFCI power cord to proper receptacle and voltage.
8. While holding onto hose firmly to prevent hose from whipping
around, turn the jet power switch on.
9. Guide the jet hose into the drain line. Do not feed the hose con-
tinuously, but rather, move the hose forward and back to allow the
pressure to break up the stoppage and the water flow to flush it
away. If you are clearing the line from the upstream side, this may
take more time. Clearing the line from the downstream side allows
debris to flow away easily.
10. The JM-1000 includes full time Pulse. The vibration generated
helps to hose overcome the friction in the line and glide farther
down the line. See Pulse section.
11. When the jet hose encounters a bend, it’s advance will usually
slow or stop. The hose has a slight bend in it from the hose reel. It
may be necessary to manually feed or rotate the jet hose to work it
around the bends. If the hose won’t advance, put the hose in a
loop and rotate it a quarter to half turn so the curve of the hose
matches the pipe. It may also be necessary to pull the hose back
six inches and snap it forward to hop across a gap in the pipe
fitting.
12. Once you reach the stoppage, pass the hose back and forth
through the section several times to ensure the line is thoroughly
cleared. You may also switch nozzles to a wide spray or rotary
(optional) nozzle for wall to wall cleaning action.
OPERATION
NEVER POINT THE END OF THE JET HOSE AT A
PERSON WHILE OPERATING.
MAINTENANCE
Regular inspection is the key to preventing breakdowns and prolong-
ing the life of the equipment. Follow this simple procedure religiously.
DAILY
Check INLET STRAINER for debris before each use.
Check that the jet nozzles are not clogged or worn out.
Clean nozzles between each use.
WEEKLY
Check the pressure hose for wear and damage. Damaged hose
can be repaired at a local service dealer, or by your equipment
dealer.
DISCONNECT JETTER FROM POWER SOURCE
BEFORE PERFORMING MAINTENANCE OR MAKING
ANY ADJUSTMENTS.
