Gardena 5900/4 inox Betriebsanleitung Seite 8

Intended use:
The GARDENA Submersible Pressure Pump is intended for the extrac-
tion of water from wells, shafts and other water reservoirs, for the opera-
tion of irrigation equipment and systems, also for pumping rainwater, tap
water and water containing chlorine. Art. 1771 / 1773 are also intended
for domestic water supply in private domestic gardens and allotments.
Liquids to be pumped:
The GARDENA Submersible Pressure Pump must only be used to pump
water. The pump is fully submersible (water-tight encapsulation) and is sub-
merged in water (for max. submersion depth, see 7. TECHNICAL DATA).
The pump is equipped with an integrated check valve, which prevents
automatic drainage of the pressure hose when the pump is shut down.
The product is not intended for long term use (continuous circulation
operation).
DANGER! Risk of injury!
The pump should not be used for the delivery of salt water,
muddy water, corrosive, easily inflammable or explosive liquids
(e. g. petrol, paraffin, thinners), oil, heating oil or foodstuffs.
1. SAFETY
IMPORTANT!
Read the operator's manual carefully before use and keep for future
reference.
Symbols on the product:
Read operator's manual.
General safety warnings
Electrical safety
DANGER! Electric shock!
Risk of injury due to electric current.
v The product must be supplied through a residual current device (RCD)
having a rated residual operating current not exceeding 30 mA.
DANGER! Risk of physical injury!
Risk of injury due to electric current.
v Disconnect the product from the mains before you maintain or replace
parts. Thereby the disconnected socket must be in the visual range.
Safe operating practices
The water temperature should not exceed 35 °C.
The pump must not be used when people are in the water.
Pollution of the liquid could occur due to leakage of lubricants.
Circuit breakers
Dry-running protection:
If the water level is too low, the pump switches off automatically.
v Submerge the pump deeper into the water.
Thermal protection switch:
In the event of an overload, the pump is switched off by the built-in thermal motor
protection. After sufficient cooling of the motor, the pump is operational again.
Leakage protection (only for Art. 1771 / 1773):
The event of leakage on the pressure side (e. g. leaking pressure hose or tap)
switches the pump on and off at short intervals. If the pump is switched on and
off more frequently than 7 x in 2 min. (with a leakage < 6 l/hr), the pump switches
off completely. When the leakage on the pressure side is eliminated, the pump
must be unplugged and plugged in again in order to be operational again.
Automatic venting
This pump is equipped with a vent valve which eliminates any air pockets in the
pump. Depending on the function, a small amount of water can escape below
the handle.
Additional safety warnings
Electrical safety
DANGER! Cardiac arrest!
This product makes an electromagnetic field while it operates. This
field may under some conditions interfere with active or passive medical
implants. To decrease the risk of conditions that can possibly injure or
kill, we recommend persons with medical implants to speak with their
physician and the medical implant manufacturer before you operate the
product.
Cables
If extension cables are used, these must comply with the minimum cross-
sections in the table below:
8
1768-20.960.01.indd 8
Voltage Cable length
230 – 240 V / 50 Hz Up to 20 m
230 – 240 V / 50 Hz 20 – 50 m
DANGER! Electric shock!
With a cut off mains plug, moisture can get into electrical parts via the
mains cable and cause a short circuit.
v Never cut the mains plug off (e. g. to feed through wall).
v Don't use the power cable for plugging off.
v If the supply cord is damaged, it must be replaced by the manufacturer,
its service agent or similarly qualified persons in order to avoid a hazard.
Mains plug and extension connections must be protected from water splashes.
Ensure that the electrical connections for plugs and sockets are made in areas
safe from flooding.
Protect the mains plug and the mains power cable from heat, oil and sharp
edges.
Observe the mains voltage. The information on the nameplate must be in
agreement with the data for the mains power grid.
The pump's mains plug must be disconnected before anybody enters the
swimming pool.
The mains power cable must not be used for fastening or transporting the
pump.
For submerging or lifting / securing the pump, please use the fastening rope.
Please regularly check the connecting line.
Before using, always subject the pump (especially the power cables and the
power connections) to a visual inspection.
A pump which is damaged should not be used. In the event of damage, have
the pump checked by GARDENA Service.
Do not disassemble the pump any further than the delivery condition.
Before use after maintenance, make sure that all parts are screwed together.
When using our pumps with a generator, the warnings of the generator
manu facturer must be observed.
Personal safety
DANGER! Risk of suffocation!
Small parts can be easily swallowed. There is also a risk that the poly-
bag can suffocate toddlers. Keep toddlers away when you assemble the
product.
Observe the minimum water level in accordance with the characteristics given
for the pump.
Only for Art. 1768: Allow the pump to run no longer than 10 minutes against
a closed pressure side.
Sand and other abrasive substances cause increased wear and reduce the
pump's output.
The pump must not be used to increase the pressure through the thread on
the inlet side.
Only the GARDENA floating suction system may be mounted on the thread on
the inlet side.
The float switch may only be operated outside the water.
The hose must not be disconnected during operation.
Allow the pump to cool down before troubleshooting.
2. ASSEMBLY
DANGER! Risk of injury!
Injury when the product starts accidentally.
v Disconnect the product from the mains before you assemble
the product.
The hose can be connected via the pump connection
tion nipple (2) [19 mm (3/4") / 25 mm (1")] or via the GARDENA Connection
System [13 mm (1/2") / 16 mm (5/8") / 19 mm (3/4")]. When using a 25 mm
(1") hose, the pump has the maximum delivery capacity.
With a parallel connection of more than one hose or connected devices,
the GARDENA 2- / 4-Way Valve (Art. 1210 / 1194) can be used.
