5.1.2 Camera cable
Fig.
5: Inspections using camera cable
from above
The most effective method of inspecting things
such as chimney and downpipes is from above, for
example when standing on the roof. To do so, it is
necessary to connect a camera cable to t
he moni-
tor.
5.1.3 Cable reel
Fig. 6: Wöhler cable reel with camera
head connected
The Wöhler cable reel can store up to 30 m of
camera cable and proves extremely useful when
working with the cable. The monitor is secured to
the cable
reel using the connection for the telescop-
ic stand.
5.1.4 Camera viper
Fig. 7: Wöhler camera viper
If it is not possible to perform an inspection from
above, it will be necessary to connect a camera
viper
. It is far easier to handle
the camera rod when
used in conjunction with a Wöhler camera viper,
which can store up to 30 m of camera rod.

WARNING!
Risk of injury when handling the rechargeable
batteries improperly!
Never open the rechargeable battery housing.
Do not throw rechargeable batteries into a fire or
expose to high temperatures. There is a risk of
explosion!
If handled improperly, a liquid may emerge from
rechargeable batteries that can cause skin irritation. Avoid contact with the liquid. Rinse skin with
large amounts of water if it comes into contact
with the liquid. If the liquid comes into contact with
eyes, rinse with water immediately for 10 minutes
and consult a doctor immediately!
WARNING!
Danger of death by electrocution!
Never touch an electrical outlet with wet hands!
Do not expose the power pack to moisture!
Never pull the cable to remove the power pack
from the electrical outlet - it could rip out the cable!
Operate the power pack only when the mains
power supply is the same as the voltage stated on
the rating plate!
CAUTION!
Switch off the camera system before charging the
battery.
CAUTION!
If the camera is not used regularly, we recom-
mend to discharge the battery by powering on the

indicates the downward gradient of the pipe.

ward grade of 13°.

Camera head facing vertically upwards: + 90°
Camera head facing vertically downwards: -90°

the camera head aligns itself so that the display is
parallel with the ground above (this function is

16 Guide accessories
This section contains some recommendations based on our experience about the se-
lection of guide accessories for the inspection in tubes and ducts.
As all pipes and chimney systems are different, the user has to decide about the guide
accessory in every single case. For the selection of the correct tool it is important to
consider that the guide accessory has to facilitate the introduction and the extraction of
the camera head, as well as an adequate guidance. The danger of jamming or getting
stuck in the tube has to be avoided.

18.1 Replacing the dome of
the camera head
Fig.
31: Fitting the camera dome
NOTE!
Wöhler's Ø 40 mm pan&tilt camera head is supplied ex-works protected by a plastic dome, which
can be replaced if necessary. If it becomes
scratched, i
t is optional to fit this camera head with
a glass dome for use in dry working environments.
The Ø 51 mm camera head is always supplied
with a real glass dome, which it is possible to replace if required!
Apply silicone grease before fitting the new dome.
When fitting the replacement dome, make sure
you cover all of the thread to ensure it is properly
tightened. Otherwise, it cannot be guaranteed that
the camera head is properly sealed, and malfunctions can occur as a result of water and dirt penetration.
18.2 Monitor
Clean the monitor using a soft cloth.
