Drain Preparation; Hose Set-Up - RIDGID KJ-2200-C Operator's Manual

KJ-2200/KJ-3100 Water Jetting Machines
Fill the tank prior to starting the jetter. When starting
jetter, turn the tank valve off. As soon as the jetter is
started, open the tank valve. Monitor the tank water
level, and if needed, stop jetting to allow the tank to
refill. Do not allow the water level to fall below the hose
end.
Hot water can be used for improved cleaning. Do not
use water hotter than 140°F / 60°C – this can cause the
pump thermal overload to open. When using hot wa-
ter, use appropriate personal protective equipment to
reduce the risk of burns.
When using in cold weather, use precautions to pre-
vent water from freezing in the pump. This can dam-
age the pump.
Make sure that the inlet supply valve on the jetter is
closed and attach the supply hose to the jetter.

Drain Preparation

If working through a manhole, storm grate or other
large access, use pipe and fittings to create a guide for
the jetter hose from the drain opening to operation
point. This will prevent the jetter hose from whipping
around in the access and protect the hose from dam-
age.

Point

Hose Set-Up

Use care when routing jetter hoses. Routing hoses over
rough surfaces, sharp edges, crossing hoses, etc. can
damage the hose jacket, especially when the jetter is
used in the pulse mode. Keeping the jetter hose on the
reel will help to minimize hose damage.

90 cm of the drain opening. Do not allow excessive
amounts of hose outside of the drain to prevent
hose damage. If the hose reel cannot be placed
within 3 feet / 90 cm of the drain opening, extend
the drain opening back to the hose reel with similar
sized pipe and fittings.
