DANGER
Risk to life
– Cables and components of photovoltaic
installations are always live during inci-
dence of light. Touching live parts can
lead to electric shock and is prohibited.
Do not perform any cleaning work in the
vicinity of power lines or other electrical
installations.
Direct your special attention to the han-
dling of the telescopic lance in the vicin-
ity of power lines.
WARNING
Risk of falling! When performing cleaning
work in greater heights.
– Use personal protective equipment, ap-
proved fastening points must be availa-
ble and used.
Please observe the following standards
concerning safe work with protective
equipment: e.g. EN 358, EN 361,
EN813, EN1497
There is a tripping hazard due to the
safety rope and the high-pressure
hose. Always ensure that the high-pres-
sure hose and the safety rope are care-
fully placed down.
Appropriate climbing aids (e.g. scaffold
or lifting platforms) must be in place.
Ensure that the admissible roof load is
not exceeded during cleaning work
from the roof. In case of any uncertain-
ties, contact the builder.
Be particularly careful with corrugated
sheets made of asbestos cement or bi-
tumen, light domes or glass roofs as
well as old or damaged roof tiles. They
may only be stepped on if there are
special access or working boards.
Keep handles, steps, rails, platforms,
and ladders free of dirt.
Do not perform cleaning work in strong
winds.
Danger of slipping!
– Do not step on the roof in damp weather
conditions.
Risk of injury!
– Never touch the rotating brush with your
fingers.
– Prior to starting cleaning work on the
roof, a sufficiently large area on the
ground must be cordoned off by means
of barrier tape and/or "Caution roof
work" signs.
Persons might get injured by falling ob-
jects. Keep persons out of the cleaning
area while cleaning.
Wear suitable protective gloves, safety
goggles and safety gear during work.
CAUTION
Risk of breakage!
– Do not step on the modules, they can
get damaged by stepping on them.
In case of high outside temperatures, it
is recommended to preheat the water
(max. 40 °C) to avoid tensions in the
glass due to high temperature differ-
ences. Preferably perform cleaning
when the modules are not exposed to
sunlight.
8
Risk of damage!
– Soiled and dry brushes can damage the
module surface. Always keep bristles
free of dirt or sand.
Do not hit or scratch the surface with
the telescopic lance or the cleaning
brush.
Do not push brushes over dry modules.
Do not perform cleaning work in minus
temperatures.

Preparation
Securing the cleaning area
 Prior to starting cleaning work on the
roof, a sufficiently large area on the
ground must be cordoned off by means
of barrier tape and/or "Caution roof
work" signs.
Attaching the high-pressure hose to
the telescopic lance
Illustration
 Completely push the telescopic lance
together.
Illustration
 Unscrew the connection thread from
the telescopic lance.
Illustration
 Fully uncoil the high-pressure hose and
lay it out lengthwise.
 Insert the thin end of the high-pressure
hose in the guide of the telescopic lance
until it exits the front of the lance.
Illustration
 Screw the connection thread onto the
high-pressure hose. Use soluble metal
adhesive (e.g. Loctide 243).

Note: Use a hexagon key SW 6 for
tightening.
Illustration
 Screw the connection thread approx.
1.5 cm into the thread of the telescopic
lance and fix by a locknut.
Note: Ensure that the nut does not pro-
trude into the thinner thread.
Illustration
 Connect the high-pressure hose to the
telescopic lance.
Caution: Operating the cleaning brush-
es directly on the trigger gun of the
high-pressure cleaner leads to damage
of the drive of the cleaning brushes and
is thus prohibited!
Information for working with a spray
lance: If a standard or flexible spray lance
(special accessories) can be used due to
the cleaning conditions, a ball tap (special
accessories) must be installed between the
high-pressure hose of the high-pressure
cleaner and the spray lance instead of the
trigger gun, see Chapter "Special accesso-
ries".
Connecting the cleaning brushes
with distributor and telescopic
lance (iSolar 800 only)
Illustration
 Screw the cleaning brushes onto the
connection of the distributor, do not
tighten them yet. Mind the brushes' di-
rection of rotation!
 Place the brushes on a flat surface for
installation and tighten the brushes.
 Screw the distributor with the installed
brushes onto the connection of the tele-
scopic lance and tighten it.
Connecting the cleaning brush with
telescopic lance (iSolar 400 only)
Illustration
 Screw the cleaning brush onto the con-
nection of the telescopic lance and
tighten it.
Connecting the high-pressure
cleaner to the telescopic lance
Illustration
 Connect the high-pressure hose of the
high-pressure cleaner to the telescopic
lance.
Note: Unscrew the hand spray gun
from the high-pressure hose first.
 If a ball tap (special accessories) is in-
stalled between the high-pressure hose
of the high-pressure cleaner and the
spray lance, you can work with the
standard spray lance of the high-pres-
sure cleaner or with the special acces-
sory flexible spray lance.
Operations
Tips for cleaning
– Moisten the first row of modules using
the water hose. This removes stubborn
soiling and the scrubbing of the brush
on a dry surface is avoided.
– Cleaning from the roof ridge: Clean the
modules from top (telescopic lance re-
