Always switch the system on and off using the power controls.
Never lower tractors or other heavy equipment into manholes while personnel are working in the
manhole.
To avoid risk of burns do not touch lightheads when they are switched on or immediately after switch
off. Leave ample time for them to cool before handling.
Clean and sterilize equipment at regular intervals.
Explosion Proof (EX) camera systems have been certified by approved certification authorities. Users
of such systems must ensure that they are operated and serviced according to the instructions
contained in the User and Maintenance manuals. It is the responsibility of the user to decide if the
systems are suitable for use in a particular environment.
Guidance Notes for using CCTV equipment in sewers
All equipment should be properly maintained and should be checked before use to ensure it is
functioning safely.
Select and cone off area to be surveyed. Use appropriate signs for directing traffic flow.
Remove manhole covers from survey area. Where reasonably practicable at least one manhole
above and one below the length of pipe to be surveyed should be removed.
If personnel are to enter the manhole, insert an approved gas monitor, on a line, to test the
atmosphere at the pipe level where manhole covers have been raised.
If all the above tests are negative, leave a gas monitor in the sampling mode at the beginning and end
manholes of the area to be surveyed.

P571 flexicoiler Operation Manual iii
Place the survey vehicle and other associated equipment no less than 5 feet (1.5 meters), horizontally,
from the end of the manhole.
Proceed with surveying as per CCTV manufacturers' instructions.
In the event of an alarm on the gas monitor, DO NOT ENTER MANHOLE.
Persistent alarms may require jetting operations or opening more manholes above and below the area
to be surveyed to increase ventilation.
When the survey has been completed, the above sequence of operations should be reversed and, in
particular, the removal of the gas monitors should be left until the end.
Please ensure all personnel observe the NO SMOKING rule throughout the time the manhole covers
are removed.

Section 2 - Preparation and connection
1. Introduction
This Section details the correct procedure to safely prepare and connect the P571 flexicoiler System.
WARNING: Risk of explosion.
Do not use any Explosion Proof equipment if there is damage to the body or any other part. The explosion
proof certification maybe violated rendering the equipment unsafe to use in a hazardous environment. Contact
your Pearpoint representative immediately.
Cautions:
1. Any repair work to Explosion Proof equipment must be carried out by an approved person, only.
2. Before proceeding to connect your system, read the section below on flame paths.
2.1.1 Flame paths
At all stages of operation, particular attention must be given to flame paths because the condition of all
flame paths affect the safe operation of the equipment. Within this manual there are illustrations which
show the locations of the flame paths for all of the Explosion Proof items of the system. You will note
that they are, without exception, the external mating surfaces of revolving joints.
The critical features are:
The surface finish of the mating faces
The gap between the mating faces
The length of the mating faces
You must not, as part of any operational or maintenance procedure, do anything which will:
Roughen the surface finish on the face
Change the width of the gap between the mating faces
Reduce the length of the mating faces
If you know, or suspect, that any of the critical features have been adversely affected during surveying
operations, you must take immediate steps to correct the problem. However, this type of problem would
normally occur only as a result of severe impact damage or if there had been an explosion within the
device.
If equipment returned for maintenance has suffered an internal explosion, it is imperative that all the flame
paths are checked before returning it to use. Damage to the surface finish can only occur as a result of
careless assembly since once the equipment is assembled all of the mating surfaces are protected.
Damaged flame paths cannot be reworked. A new, replacement part must be fitted.
It is important to inspect flame paths at regular intervals. We suggest six months as the maximum
interval to ensure that the surface finish and dimensions are correct. If the equipment has been stowed
with its protective caps in place and has not suffered impact damage, it is unlikely that there will be any
damage to the flame paths.
To summarize: Equipment which is carefully assembled and disassembled during survey work should
not suffer damage to flame paths. During surveying, flame paths may suffer damage as the result of
internal explosion or if visible impact damage occurs.

3. Equipment preparation
This section details the preparation to the P571 flexicoiler which is necessary prior to commencing the
survey. Most of the checks are to ensure that the equipment is safe to use. Other checks, if carried out
correctly, will ensure that the equipment operates correctly during the survey.
2.3.1 P571 preparation
WARNING: Risk of explosion.
Do not use the P571 flexicoiler if there is damage to the body or any other part. The certification may be
violated rendering the equipment unsafe to use in a hazardous environment. Contact your Pearpoint
representative immediately.
WARNING: Risk of injury.
Heavyduty gloves and safety goggles should be worn when handling rod. Any abrasions or damage on the
rod outer covering can cause injuryto unprotected hands.
Figure 2.1 P571 flexicoiler - Preparation
1. Check the power cable (Item 1) for damage and security. If the cable or plug is damaged in any
way it must be replaced.
2. Inspect the frame (Item 2) to ensure that there is no damage or distortion. Inspect all welds for signs
of cracking. If any damage is apparent, contact your Pearpoint representative for advice.
3. Check the condition of the hub connector. Ensure it is secure and not damaged or dirty. If the
connector has been damaged, contact your Pearpoint representative for advice.
4. Remove all rod from the coiler and inspect for damage. If the rod is damaged, water may leak
through the outer covering and damage the equipment. Contact your Pearpoint representative
for advice.
NOTE: It is also necessary to calibrate the rod before use. This will ensure that the rod counter will give
accurate measurements. See Section 3 for details.

P571 flexicoiler Operation Manual 11
5. Check the security of the monitor locking hand wheel (Item 5). Turn the hand wheel anticlockwise to
loosen and push the monitor to the upright position. Turn the hand wheel clockwise until hand tight
to secure the monitor. The monitor should remain in the upright position.
CAUTION: Equipment Damage.
If the monitor fails to remain upright, there could be a fault in the hand wheel mechanism. This must be
repaired otherwise damage to the monitor may result. Contact your Pearpoint representative for advice.
