Drain Preparation; Hose Set-Up - RIDGID KJ-2200 Mode D'emploi

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. – this can cause the pump
thermal overload to open. When using hot water, use
appropriate personal protective equipment to reduce the
risk of burns.
When using in cold weather, use precautions to prevent
water from freezing in the pump. This can damage 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 ac-
cess, use pipe and fittings to create a guide for the jetter
hose from the drain opening to operation point. This will pre-
vent the jetter hose from whipping around in the access and
protect the hose from damage.

Operation 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.

1. Select a jetter hose size appropriate for the drain
being cleaned. It is not generally recommended to
connect two jetter hoses together for cleaning drains.
The connection between the two hoses is less flexible
and can prevent passage through fittings See Jetter
Hose Selection Chart.
2. As needed, separate the hose reel from the mot -
or/pump assembly. Locate the hose reel within 3 feet
of the drain opening. Do not allow excessive amounts
of hose outside of the drain to prevent hose dam-
age. If the hose reel cannot be placed within 3 feet of
the drain opening, extend the drain opening back to
the hose reel with similar sized pipe and fittings.
3. Route a hose from the jetter to the IN fitting on the foot
valve. Use PTFE tape to seal the connection. Position
the foot valve for accessibility. You must be able to
control the jetter hose and the foot valve.
4. Connect the hose from the reel to the OUT fitting
on the foot valve.

5. Mark the jetter hose near the end to indicate when the
nozzle is getting close to the drain opening when
withdrawn. This will help prevent the nozzle from
coming out of the drain and whipping around. The dis-
tance depends on the configuration of the drain, but
should be at least 4'/1.2 m.
6. Remove the nozzle from the end of the jetter hose
and place the end of the jetter hose in the drain.
Open the inlet supply valve to purge the air and any
debris from the jetter and hoses. Allow water to flow
for at least 2 minutes.
7. Close the inlet supply valve.
8. Select a nozzle. Use nozzles specifically sized for the
jetter being used. Using incorrect nozzles can cause
poor performance (low operating pressure or low
flow) or may damage the jetter with excessively high
