Installation Operating Manual

5Installation

5.1 Assembling the tools

All tools are supplied ready to be used. Once the tools have been unpacked, please

check the content for completeness.

5.2 Preparatory work

It makes sense to clarify some points before use. Knowledge of the following points is

helpful during preparations and when adjusting the wire rope and chain scraper:

•Layout of the pipes

•Inner pipe diameter of the channel where work will be performed

•Pipe material of the channel where work will be performed

•Type of foreign material in the pipe

•Planned flushing direction →We recommend that you work against the direction

of flow.

•Any type of gradient in the channel where work will be performed

•Access points to the channel

5.3 Setting up the work area

Prior to working with a wire rope or chain scraper, the following procedures must be

followed:

Set up barriers and safety equipment (warning triangle, block off the area, etc.)

The work area must be blocked off and secured so that there is no risk of falling

or other traffic-related dangers.

The necessary information on the wastewater flowing through the manhole must

be obtained (chemicals, gas, vapors, etc.)

Measuring instruments such as explosive gas meters, oxygen meters, gas warning

devices, etc. must be readily available.

You must ensure that the appropriate nozzle sizes for cleaning the pipes are avail-

able. The application range of each nozzle is listed in the "Technical data" section

on Page 14.

Operating Manual Installation

The layout of the pipes (manhole drawings) must be known before starting the

work so that the nozzle can be prevented from emerging at a pipe end. Support

personnel must be on hand to monitor possible emerging points.

Have the liability waiver signed by the customer to protect against any claims for

damages.

If the tools are heavy, then a tripod winch is required to lower the wire rope or

chain scraper into the manhole. It should not be lowered into manhole by the

hose.

5.4 Adjusting the wire rope and chain scraper to the channel diam-

eter

A wire rope or chain scraper must always be adjusted to the inner diameter of the

pipe where work will be performed.

Chain lengths are selected to ensure that the ends are always scraping against the

pipe wall. The only exception is if the work is to be performed in an ovoid profile. Re-

fer to Drawing 1 for the 10.200R example. This prevents the tool from rotating too

fast during operation and causing unnecessary damage to the tool and the channel.

The skids can be adjusted on some articles in the wire rope and chain scraper series;

in others, the skids and the chains are replaced based on the channel pipe diameter.

Figure 1 Blocked off & signed work area

Installation Operating Manual

When adjusting the skid and cage settings, always use the largest possible setting for

the inner channel diameter being worked on.

To correctly install your wire rope or chain scraper, please refer to the pages specifi-

cally about your product in Section 8. You will find tool-specific information on the

chains, ropes and skids to be used and how to adjust them there.

CAUTION

Always use the correct chain or rope length. The chains or

ropes must drag along the pipe wall, and they must not strike

the wall! Otherwise, the pipe wall or the product could be-

come damaged.

Operating Manual Operation

6Operation

6.1 How to operate the tools

1. Flush all loose debris from the pipe prior to working with a standard nozzle. Loose

debris can interfere with the work. If need be, you must use a pointed nozzle or

a Bulldog, with their specialized center spray features, to clear the pipe of roots.

2. The chain scraper is screwed onto the hose unrolled from the vehicle. The thread

size depends on the size of the tool and can be found in the section “1.1 Technical

data” on Page 14.

3. Push the wire rope or chain scraper at least half of its length into the pipe to be

cleaned. If possible, you should work against the direction of flow.

4. Increase the pressure on the wire rope or chain scraper up to 100–120 bar (while

paying attention to any loss of pressure in the hose).

5. Keep an eye on the forward motion while unrolling the hose and pay attention to

the noise from the work. If you notice any irregularities, refer to Troubleshooting

in Section 6.6 on Page 21.

6. Also allow water to run when retracting the wire rope and chain scraper so that

the nozzles do not become clogged.

7. Close the manhole cover once work is completed.

Normally, the nozzle will turn in a counter-clockwise direction when in use. Mean-

while, the connecting thread will turn in a clockwise direction. This prevents the nozzle

from detaching itself from the connecting thread during operation.

6.2 Cleaning easily damaged pipes

Work on pipes that are made of one of the following materials should be performed

with the utmost care due to their low mechanical strength properties:

Plastic (PE, PVC, and more…)

Clayware

Glass fiber-reinforced plastic (GFK)

Continue to run the water at low pressure when retracting the

tool. This prevents wastewater from entering the interior of

the nozzle, which can lead to failure.

Operation Operating Manual

6.3 Cleaning pipes with minor damage

Slightly damaged pipes usually exhibit cracks in the pipe wall. If detected, always con-

tact the customer or the appropriate authorities.

When working inside a slightly damaged pipe, extreme caution must be used. Use of

the tool is always at your own risk! enz® technik ag waives all liability!

6.4 After use

After you have completed work, you must still do the following:

1. Rinse the tool with fresh water.

2. Spray OIL SPRAY BIO (Item no. C191) on the entire tool. Then manually turn the

rotor several times.

3. Then check the tool for traces of wear and replace any defective parts if needed.

6.5 Completing the work process

If possible, use a special camera to inspect the cleaned pipes. Look out in particular for

any damage and ensure that no liquids can escape into the environment.

All manholes must be closed after the cleaning has been completed.

CAUTION

If the pressure is too high, the cleaning jet can damage or

cause a break in the pipe wall. This could result in interrup-

tions to the work or material damage.

DANGER

When cracks are washed out, pipe fragments can break off

and the material surrounding the pipe may be flushed out.

When in doubt, you should not use the product. Using it in

these circumstances can result in collapsed channels and ac-

companying injuries or death.
